How can i do Facebook Live (page) using FFMPEG - facebook

SOLVED & EDITED -
Catch: Doing live stream on Facebook with FMMPEG.
In past it was easy i did many times as facebook was using rtmp.
But now facebook is using RTMPS so i am getting different errors i have tried 100 commands.
I have a image test.png and a audio file test.m4a (its a podcast) and facebook stream key is 1234.
( i have tried 100 types of commands so cant post here and cant post errors aswell.)
so please can someone help me to go live on my facebook page with image+m4a file.
i prefer centos but i will manage ubuntu if you prefer.
Regards..
Solved : See my answer might help someone.

SOLVED
Hope it will be useful for someone.
I was trying with all possible results from google and stackoverflow.
nothing worked.
Then i did my own way and it worked after 2 hour.
i will stream video out.mp4 from my server on Facebook.
Install FFMPEG4 ( older version has issue with rtmps )
ffmpeg -re -y -i out.mp4 -c:a copy -ac 1 -ar 44100 -b:a 96k -vcodec libx264 -pix_fmt yuv420p -tune zerolatency -f flv -maxrate 2000k -preset veryfast "rtmps://live-api-s.facebook.com:443/rtmp/key"
You can stream on as many platforms as you want.
PS. if you want to stream image+audio replace our.mp4 .
but i used ffmpeg to make video from m4a file ( it will stream without lag) & buffer)

If you are on CentOS or Redhat, you may find it difficult to intall ffmpeg. Or your installation can miss some of the libraries/protocols required by ffmpeg to be able to do FB live. For this purpose, running docker image would be a great idea:
Install docker and pull ffmpeg docker image
Run docker ffmpeg image with necessary arguments
For Installing docker, run following commands:
remove older version of docker if installed
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
install docker yum repository
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
install docker and start/enable docker service
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo systemctl enable docker
Reference : https://docs.docker.com/engine/install/centos/
To run ffmpeg for FB live, run following command:
docker run -v $(pwd):$(pwd) -w $(pwd) jrottenberg/ffmpeg -re -y -i [VIDEO_FILE] -c:a copy -ac 1 -ar 44100 -b:a 96k -vcodec libx264 -pix_fmt yuv420p -tune zerolatency -f flv -maxrate 2000k -preset veryfast "rtmps://live-api-s.facebook.com:443/rtmp/[KEY]"
replace [VIDEO_FILE] with the file you want to stream live to fb and [KEY] with the stream key from facebook. Reference : https://hub.docker.com/r/jrottenberg/ffmpeg/
Please note that you need to visit facebook live page (https://www.facebook.com/live/producer/) before you can run the above command.

Thanks Mate for your answer. even you are late anyway i did something similar.
I have already figured it by using DOCKER.
using Restreamer : https://datarhei.github.io/restreamer/
It work on both centos & Ubuntu
Aslo i tried it manually it was very difficult to install and setup but i did that and will not recommended.

Docker-compose: /usr/local/bin/docker-compose : line 1: Not: command not found

i'm trying to install Docker-compose on my Raspberry Pi 3+ which installed Raspbian buster.
I followed instruction on docker.com. After I entered command : sudo curl -L https://github.com/docker/compose/releases/download/1.20.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose.
It show a table for downloading
Result
It seems nothing downloaded, just have a file docker-compose saved in /usr/local/bin/docker-compose. When I opened it, it empty. Then I enter command docker-compose -v, it displayed error /usr/local/bin/docker-compose : line 1: Not: command not found.
Anyone have solution?
UPDATE:
Added the following command to my answer to download the LATEST version without specifying any version number at all so the download can be scripted.
curl -L "https://github.com/docker/compose/releases/download/$(curl https://github.com/docker/compose/releases | grep -m1 '<a href="/docker/compose/releases/download/' | grep -o 'v[0-9:].[0-9].[0-9]')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
It's a bit untidy, but it works. If you have a more elegant way than mine, ping it to me in the comments and I'll update my answer.
Just need to set the perms on the file:
chmod +x /usr/local/bin/docker-compose
Use the file command to validate that you pulled the correct arch for your system.
Intro:
Although docker-compose can be installed from a repo per the accepted answer, apt-cache show docker-compose reveals that as of 20211201 the repo version is only v1.25; about 2 years behind the current v2.1.1 release. In order to take advantage of more modern docker file versions, I needed to get the Github download working.
Short Answer:
The Docker documentation for Docker-Compose is WRONG. They forgot to preface the version number in the command with a "v"; consequently the download fails. Apparently this has been wrong for ages...
Longer Answer:
I ran the below command from the Docker-Compose documentation, and substituted the version "2.1.1" for "1.29.1" per Docker's guidance:
To install a different version of Compose, substitute 1.29.2 with the
version of Compose you want to use.
sudo curl -L "https://github.com/docker/compose/releases/download/2.1.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
The resulting download was 9 KB for a 23 MB binary. Clearly the link was bogus. So I went to the root of the address used in the command "https://github.com/docker/compose/releases" and right-clicked on the version of Docker-Compose that I wanted and chose "Copy Link Address"
This revealed the link Docker was telling folks to use didn't have a "v" prefaced before the version number in the https:// address part of the command.
Solution:
Preface a "v" before the version number you want in the link as below and the command executes successfully:
sudo curl -L "https://github.com/docker/compose/releases/download/v2.1.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
BTW, I too was downloading docker-compose for a Raspberry Pi using the aarch64 binary for Ubuntu 20.04 LTS. However, the missing "v" fix for the broken download address should work for any platform.
This is because on a raspberry pi the url part of the command results in
https://github.com/docker/compose/releases/download/1.24.1/docker-compose-Linux-armv7l
Looking at the latest stable release at https://github.com/docker/compose/releases/tag/1.24.1 you can see there is no download for the armv7l architecture so the file is empty because there is nothing to download.
Will update answer once I figured out how to install docker-compose on Raspian.
Edit:
Via apt-get. Note: Currently (Nov. 8 2019) this installs version 1.21 which is not the latest available.
sudo apt-get install docker-compose
Via pip3. (Installs latest)
sudo apt-get install python3-pip
sudo pip3 install docker-compose
And then restart your system with
sudo shutdown -r

ubuntu 16 install gstreamer but gstreamer-plugins-base-1.0.pc file is not found anywhere

(Using ubuntu 16 0n my mac pro.)
To integrate gstreamer and pocketsphinx, I need three .pc files as the offical website says:
gstreamer-1.0.pc
gstreamer-base-1.0.pc
gstreamer-plugins-base-1.0.pc
I start a new empty ubuntu 18.
install the gstreamer through
$ sudo apt-get install libgstreamer1.0-dev
But only two of the three important .pc files exist after the previous command.
If I cd to /usr/ and run :
sudo find . -print | grep -i 'gstreamer-plugins-base-1.0'
the terminal returns empty( not found).
At the same time,
sudo find . -print | grep -i 'gstreamer-base-1.0'
and
sudo find . -print | grep -i 'gstreamer-1.0'
will give me correct paths.
Where is the missing gstreamer-plugins-base-1.0.pc file? Thank you.
If there are only two but not three of the .pc files, the configuration of pocketsphinx will not work.
**sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev**
helped me generate the missing gstreamer-plugins-base-1.0.pc file.
Those two are needed.

How to upgrade docker-compose to latest version

I have installed docker-compose using the command
sudo apt install docker-compose
It installed docker-compose version 1.8.0 and build unknown
I need the latest version of docker-compose or at least a version of 1.9.0
Can anyone please let me know what approach I should take to upgrade it or uninstall and re-install the latest version.
I have checked the docker website and can see that they are recommending this to install the latest version'
sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
But before that, I have to uninstall the present version, which can be done using the command
sudo rm /usr/local/bin/docker-compose
but this can be used only when the installation was done using curl. I am not sure if the installation was done by curl as I have used
sudo apt install docker-compose
Please let me know what should I do now to uninstall and re-install the docker-compose.
First, remove the old version:
If installed via apt-get
sudo apt-get remove docker-compose
If installed via curl
sudo rm /usr/local/bin/docker-compose
If installed via pip
pip uninstall docker-compose
Then find the newest version on the release page at GitHub or by curling the API and extracting the version from the response using grep or jq (thanks to dragon788, frbl, and Saber Hayati for these improvements):
# curl + grep
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*\d')
# curl + jq
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
Finally, download to your favorite $PATH-accessible location and set permissions:
DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION
The easiest way to have a permanent and sustainable solution for the Docker Compose installation and the way to upgrade it, is to just use the package manager pip with:
pip install docker-compose
I was searching for a good solution for the ugly "how to upgrade to the latest version number"-problem, which appeared after you´ve read the official docs - and just found it occasionally - just have a look at the docker-compose pip package - it should reflect (mostly) the current number of the latest released Docker Compose version.
A package manager is always the best solution if it comes to managing software installations! So you just abstract from handling the versions on your own.
If you tried sudo apt-get remove docker-compose and get E: Unable to locate package docker-compose, try this method :
This command must return a result, in order to check it is installed here :
ls -l /usr/local/bin/docker-compose
Remove the old version :
sudo rm -rf docker-compose
Download the last version (check official repo : docker/compose/releases) :
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
(replace 1.24.0 if needed)
Finally, apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Check version :
docker-compose -v
If the above methods aren't working for you, then refer to this answer: https://stackoverflow.com/a/40554985
curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" > ./docker-compose
sudo mv ./docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
Based on #eric-johnson's answer, I'm currently using this in a script:
#!/bin/bash
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
output='/usr/local/bin/docker-compose'
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$(uname -s)-$(uname -m) -o $output
chmod +x $output
echo $(docker-compose --version)
it grabs the latest version from the GitHub api.
Here is another oneliner to install the latest version of docker-compose using curl and sed.
curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose
Do it in three steps. (showing for apt-get installs)
Uninstall the last one. e.g. for apt-get installs
sudo apt-get remove docker-compose
Install the new one (https://docs.docker.com/compose/install/)
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
and then
sudo chmod +x /usr/local/bin/docker-compose
Check your version
docker-compose --version
Simple Solution to update docker-compose
This will remove the existing binary of docker-compose and install a new version.
sudo cd /usr/local/bin && sudo rm -rf docker-compose
sudo sudo curl -SL https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
sudo chmod +x docker-compose
for the latest version visit https://github.com/docker/compose/releases and replace the latest one with v2.1.1
I was trying to install docker-compose on "Ubuntu 16.04.5 LTS" but after installing it like this:
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
I was getting:
-bash: /usr/local/bin/docker-compose: Permission denied
and while I was using it with sudo I was getting:
sudo: docker-compose: command not found
So here's the steps that I took and solved my problem:
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo ln -sf /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
use this from command line: sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Write down the latest release version
Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Then test version:
$ docker-compose --version
If you installed with pip, to upgrade you can just use:
pip install --upgrade docker-compose
or as Mariyo states with pip3 explicitly:
pip3 install --upgrade docker-compose
Using latest flag in url will redirect you to the latest release of the repo
As OS name is lower case in github's filename, you should convert uname -s to lower case using sed -e 's/\(.*\)/\L\1/'.
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s|sed -e 's/\(.*\)/\L\1/')-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose
On mac (also working on ubuntu):
sudo curl -L "https://github.com/docker/compose/releases/download/<release-version>/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
NOTE: write the as here:
https://github.com/docker/compose/releases
Use,
$ sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose
$ docker-compose -v
Docker Engine and Docker Compose Plugin
Since Microsoft took over Docker they worked on porting docker-compose to their Docker Engine CLI plugins. For future support and updates I would recommend using docker compose plugin (Notice the missing dash) which can be install via the docker-compose-plugin package. The following instructions assume that you are using Ubuntu as Distro or any Distro thats using apt as package manager.
Installation Preparations
Update your mirrors:
sudo apt-get update
Make sure the following packages are installed:
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
After that add the official Docker GPG Key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
And finally add the the stable repository:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Also make sure Docker Engine and other needed dependencies are installed:
sudo apt-get install docker-ce docker-ce-cli containerd.io
Installation of docker compose plugin
sudo apt-get install docker-compose-plugin
Any future updates of the plugin are easily applied via apt.
For further reference take a look at the official installation instructions of Docker Engine and Docker Compose.
After a lot of looking at ways to perform this I ended up using jq, and hopefully I can expand it to handle other repos beyond Docker-Compose without too much work.
# If you have jq installed this will automatically find the latest release binary for your architecture and download it
curl --silent "https://api.github.com/repos/docker/compose/releases/latest" | jq --arg PLATFORM_ARCH "$(echo `uname -s`-`uname -m`)" -r '.assets[] | select(.name | endswith($PLATFORM_ARCH)).browser_download_url' | xargs sudo curl -L -o /usr/local/bin/docker-compose --url
On ubuntu desktop 18.04.2, I have the 'local' removed from the path when using the curl command to install the package and it works for me. See above answer by Kshitij.
In my case, using Windows + WSL2 with Ubuntu 20.04, was necessary only this:
sudo apt update
and then:
sudo apt upgrade
Centos/RHEL
Follow my answer below if you're using Centos7 with an x86-64 architecture. This answer is also available in my github.
Stop Your Docker Containers
I noticed other answers did not talk about stopping your docker containers/images instances before attempting to upgrade gracefully. Assumptions are inevitable but can be costly. Onward we go!
Options to update Docker-Compose
There are 2 options to upgrade docker-compose if you first downloaded and installed docker-compose using the Curl command.
Using Curl, jq package, and Github's direct URL to the docker-compose repository.
Using Curl, Sed, and Github's direct URL to the docker-compose repository.
Note: some of the commands below require "sudo" privileges.
Demonstration
The script below was saved to a file called "update_docker_compose.sh". You need to give this file executable permissions.
Like so:
chmod +x update_docker_compose.sh
"docker_docker_compose.sh" file content:
#!/bin/bash
# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022
# Stop current docker container running
docker stop containerID
# Remove current docker network running
docker rm containerID
# Remove image of target application(s)
docker image rm imageID
# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f
# This step depends on the jq package.
# Uncomment jq package installation command below if using Centos7 x86-64.
# sudo yum install jq
# Declare variable to get latest version of docker-compose from github repository
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'
# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)
# Execute curl command to carry download and installation operation
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$get_local_os_build -o $target_install_dir
# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir
# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)
Edit the script with variables specific to your environment
The script above has a few variables you need to edit with values specific to your docker environment. For instance, you need to replace container ID and image ID with the values that the following commands output.
docker ps
and
docker images output
Once you finalize creating the file (including the edits). Switch to the directory that contains the file. For example, if you created the file in /home/username/script/update_docker_compose.sh
cd /home/username/script
Last, run the script by executing the following
./update_docker_compose.sh
Option 2
Create a script file name "update_docker_compose.sh"
Edit the file and add the following content:
#!/bin/bash
# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022
# Stop current docker container running
docker stop containerID
# Remove current docker network running
docker rm containerID
# Remove image of target application(s)
docker image rm imageID
# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f
# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'
# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)
# Execute curl and sed command to carry out download and installation operation
# compose_latest_version=$(curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$get_local_os_build") -o $target_install_dir
# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir
# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)
Edit the script with variables specific to your environment
The script above also has a few variables you need to edit with values specific to your docker environment. For instance, you need to replace container ID and image ID with the values that the following commands output.
docker ps
and
docker images output
Once you finalize creating the file (including the edits). Switch to the directory that contains the file. For example, if you created the file in /home/username/script/update_docker_compose.sh
cd /home/username/script
Last, run the script by executing the following
./update_docker_compose.sh
This is the method of installing docker compose version 2.12.x
Update debian package manager
# apt-get update
# apt-get install docker-compose-plugin
Then install the plugin manualy
DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
mkdir -p $DOCKER_CONFIG/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.12.2/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose
Give permisson of execution of file
chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
Last test the installation
docker compose version
// Docker Composer Version v2.12.2
If you have homebrew you can also install via brew
$ brew install docker-compose
This is a good way to install on a Mac OS system
Most of these solutions are outdated or make you install old version.
To install the latest
sudo apt install jq
DOCKER_COMPOSE_VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
sudo curl -L "https://github.com/docker/compose/releases/download/$DOCKER_COMPOSE_VERSION/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Well, my case was pretty weird. I am using wsl2, and Docker Desktop (Windows 11). I stop getting this error after rename the folder "docker" to "config-dev-server" and update de Dockerfile like this this:
COPY ./docker/apache/apache2.conf /etc/apache2/apache2.conf
to
COPY ./config-dev-server/apache/apache2.conf /etc/apache2/apache2.conf
With a newer Docker Desktop for Mac 3.3.0, you don't need to install Docker Compose as a seperate package. Docker Compose comes as a first class citizen installed with Docker by default. Check out the below CLI:
docker compose version
Docker Compose version 2.0.0-beta.1%

Where to get the eligible library tag file in Android O

In https://source.android.com/devices/architecture/vndk/deftool, it mentions that Google provides a tag file to classify the framework shared libraries, including LL-NDK, SP-NDK, VNDK, VNDK-SP and etc. However, after searching on this website and googling it, I'm not able to find the tag file. Where does Google provide it?
Thanks
Jincan
I found how to get such files.
You must get the file of vendor.img and system.img, for that is a file for deploying at "vendor partition" and "system partition" at a device.
Step 1
Please visit to Driver Binaries for Nexus and Pixel Devices.
There are images for two devices.
taimen (Pixel 2 XL)
walleye (Pixel 2)
Step 2: Method for file expand
Please read README.md.
There is undermentioned code
$ simg2img system.img system.raw.img
$ simg2img vendor.img vendor.raw.img
$ mkdir system
$ mkdir vendor
$ sudo mount -o loop,ro system.raw.img system
$ sudo mount -o loop,ro vendor.raw.img vendor
$ sudo python3 vndk_definition_tool.py vndk \
--system system \

libx264 fails on HTTP Live Streaming (FFmpeg)

I want to live stream with HTTP Live Streaming, but I have problem with libx264 or maybe something other.
My hardware and software environment:
Macbook Pro
VirtualBox with Ubuntu 16.04
Nginx and FFmpeg (in Ubuntu)
I am able to stream a static video file (in Ubuntu with Nginx and FFmpeg).
The FFmpeg command is as following:
$ffmpeg -i /my/sample/video.mp4 -codec:v libx264 -f hls /output/file.m3u8
But when it comes to webcam (live streaming), Mac OS Safari fails to open the stream. I used the following command:
$ffmpeg -i /dev/video0 -codec:v libx264 -f hls /output/file.m3u8
I guess it's the problem of libx264 because when I use mpeg2video encoder, Mac OS Safari indeed can play the stream:
$ffmpeg -i /dev/video0 -codec:v mpeg2video -f hls /output/file.m3u8
I know there is a library called video4linux2, should I use video4linux2 for capturing my webcam? But I don't know the appropriate FFmpeg command for HTTP Live Streaming (I tried FFserver but there is error something like cannot rename hls)
anyone shed some light on my problem?
I have figured it out!
The reason why Mac OS Safari cannot open a HTTP Live Streaming encoded by libx264 is because the default codec in Mac OS does not support the default output by libx264!
Simply add -pix_fmt yuv420p to the FFmpeg command and everything works fine:
$ffmpeg -f video4linux2 -i /your/webcam/path -codec:v libx264 -pix_fmt yuv420p /output/file.m3u8
