most browsers can directly display a HTTP MJPEG Stream... while they can´t display h.264 via RTSP without the help of plugins...
I have a security cam that can only stream h.264 via RTSP so I can´t view the live video on my browser (nor iPhone etc.) and I do not want to install any APPs or Plugins...
But I have a Linux Server... I would like to retrieve the h.264 on my server and restream it in MJPEG, so I can browse to my server and see the MJPEG stream via HTTP...
After three days googling around and trying a lot with live555, ffmpeg, VLC and other tools I still did not get it running...
What is the right way to achieve my goal (with free tools like ffmpeg, live555 or whatsever needed...)?
thanks for any help.
I found the answer by myself... using vlc it was important to use quotation marks :sout'....' which I did not know... now it works as expected..

Im new i streaming so sorry for stupid questions, I tried to find info in web but nothing seems to work.
What Im trying to do
I have IP Cam that puts out RTSP stream to internet its IP is: rtsp://89.79.16.127:2550
When Im accessing that stream in windows VLC (win xp) every thing works (you can tryit for yourself)
Now I have dedicated linux debian serwer with ip: 109.95.153.133
I want to setup VLC serwer that will grap rtsp feed from camera IP and restream it via my serwer, so I can show that stream on my website (located on that dedicated serwer)
Can You help mi accomplish that?
Open VLC, select Open location from clipboard
Enter the proper camera url. For example, the axis M7014 streams in H264 so its url will look like rtsp://Camera-IP/axis-media/media.amp?codec=h264
Enter the login at the prompt or encode it to the rtsp link
rtsp://user:pass#Camera-IP/axis-media/media.amp?codec=INFO.)
If the stream is playing on the screen it means you support this codec. If not, then you shouldn't try to transcode it. For example, the axis M7014 uses an H264 variant that only quicktime fully supports.
The previous steps were to determine if you can transcode or if you should just forward the traffic.
Menu-Stream, select your RTSP as a source, then add an RTSP destination and stream. If you cant see the video play you can only forward it to a player that can. beware, some RTSP headers might get tweaked and disable the ability to pause video. I can looking for a fix right now.
I'm writing an Chrome Packaged App that needs to be able to play a lot of local video files. I can use the tag to play files encoded in h.264 and mp3, but not much else. I'll require playback of at least DivX videos and AC3 audio. Is there any way to do this using the HTML5 platform or otherwise using some kind of plugin?
There are alternatives, but in my opinion the final solution is not going to be very good.
1 - You can try to use a plug-in, for example:
VLC Plug-in - sorry, I have not enough reputation to post more than 2 links :(
Divx Web Player - sorry, I have not enough reputation to post more than 2 links :(
But then you need to rely on the user installing the plug-in. For VLC, the plug-in is not compatible with the latest versions of Mac OS X.
2 - Encode to H.264 or VP8 from a server with an ffmpeg or using a cloud video provider.
3 - Encode from the client side using JavaScript! There is a port of the ffmpeg on javascript (http://bgrins.github.io/videoconverter.js/). I didn't try this method with large files.
4 - Encode from the client side using a Native Client component (https://developers.google.com/native-client/dev/). But seems a daunting task to me.
If you are going to go with the first option, assure that your audience is going to install/configure your player and that their OS are supported.
VLC ported to NaCL would be a great first step.
According to a poster on https://forum.videolan.org/viewtopic.php?f=5&t=107178, libVLC has been ported to NaCL, but I am not familiar with VLC internals so I could not say how far this gets you in terms of being able to decode different streams.
I'm interested in setting up a streaming video server (perhaps on a cloudfront server) with videojs. I understand that flash video can be streamed, however, is it possible to stream video using videojs and a different codec? (like h246). I tried looking through the videojs documentation and forums but did not find any additional info.
Video.js has limited support for RTMP streaming in Flash, but hopefully more in the next few months.
HTTP Live Streaming (HLS) is the most supported streaming format for HTML5 (iOS, Safari, latest Android). Video.js can support that on the devices that support HLS natively.
I think you would have to transcode the h264 file on the fly to get the effect you want. Subsonic is a program which will read your file structure, display your videos and music in a webui, transcode the audio/video and stream it--but it uses jwplayer, not videojs.
However, it is opensource, so if you want to try to modify that, I'm sure it would be possible.
I have a http streaming link which gives me .flv streaming feed. I want to convert that and access in my iPhone program. How can i do that? I want to have a desktop software like VLC and input this streaming feed URL and convert to iPhone supported and stream again to iPhone. I tried VLC with H.264 and Mpeg-1 audio, but seems to be it doesn't give the supported format, so as iPhone program doesn't play the video.
Could someone please guide me how can i setup a desktop software which can stream iPhone supported file?
Thanks in advance.
I think even the great VLC can't convert FLV on the fly...(or even do anything with FLV). As far as streaming goes, you'll probably be limited to the local network (Wi-Fi). I'd start with the simple way—create an ad-hoc file server on the desktop, then use AVPlayer's initWithURL method to find that video.
On the desktop, you could query the IP address of the computer, and ask the user to enter that URL (along with an optional port assignment and file component, like http://192.168.0.2:2234/streamingVideo.mp4) onto the iDevice, then convert to NSURL.
What exactly is the http streaming link? This matters a lot as in order to stream to the iPhone you need to use HTTP Live Streaming which requires some different bits than a typical flash media, or more properly RTMP, server. Typically you need two different streaming architectures or some expensive boxes.
Are there any open source projects in any language and other recourses that I need to look at in order to implement flv to 3gp conversion? It's better to be streaming, I mean return first portion of 3gp before last portion of flv is downloaded.
Or are there any similar services already implemented - my goal is to have something like
http://converter.org?source=sourceUrl.flv&targetFormat=3gp that I can feed to 3gp player, in my case - on iPhone, and not wait until server downloads entire flv.
UPDATE: ffmpeg does really good job here, just
ffmpeg -i input.flv output.mp4
and that's it. But output file can be used only after conversion is done. Streaming is still an open question. There is ffserver that does some sort of streaming but I could not make it work.
I'm not sure if it is possible, but if there's one thing that should do it.
it's http://www.ffmpeg.org/ ..
it can convert anything to anything on an online platform. don't know if it supports streaming but definitely the best solution for online video conversion
Well this one might be a little late to the party but to stream video online you'll need a Media Streaming Server to deliver the video over a specific streaming protocol (i.e. HTTP,HTTPS,RTSP,RTMP). I've also been looking for such a "real-time" transcoding service but the closest thing I've found so far is the Video CDN's which are quite pricy, and also limited in formats/support. What would be really nice is for one of the media servers to add in a real-time transcoding feature. At the time of this writing no such service exists that I know of.
The top 10 most popular options for Media Streaming Servers are (IMHO):
VideoLAN - VLC Media Player (good for quick tests and proof-of-concept)
Kaltura - Open Source video platform
Real Media - Helix Universal Streaming Server (may be best bet for 3GP over RTSP)
Apple - Darwin Streaming Server / Quicktime (Live) Broadcaster (best for iPhone/iPad)
Red5 - Open Source Flash Streaming Server
Adobe - Flash Streaming Server
Wowza - Media Server
FluMotion - Open Source Multimedia Streaming
Microsoft - Windows Media Server (AVI, WMV, Silverlight & other formats)
FreeCast - An OGG Theoris (video) and OGG (audio) streaming/conversion platform
As you can see there are many options for streaming and you can start as simply as hosting the video on the same server and delivering to Desktop computer browsers via HTTP (the easiest way to get started with this is trial & error). Each offers different features in terms of protocols supported and transcoding, but none are truly real-time as you mention where you could feed in a source video and get an output video in the format of you choosing (i.e. 3GP). My personal choice would be to start with VLC for small-scale tests on a home network, since it is basically a swiss-army knife for desktop video that can also act as a server for any of the formats it can playback (though it may be more complicated to get this to stream to the public internet and even harder to go all the way to a single device on a private carrier network, some info is available from people who've tried):
http://forum.videolan.org/viewtopic.php?f=4&t=45782
Some basic transcoding instructions to go to MP4 (required for iPhone/iPad/iPods):
http://wiki.videolan.org/MPEG-4
I also agree about FFMPEG being by far the best solution for video conversion, as it also supports 3GP and you can at least start playing around with conversion on your own test server, you might want to try the following PHP Classes project:
http://www.phpclasses.org/package/5977-PHP-Manipulate-video-files-using-the-ffmpeg-program.html
In my experience that was an excellent contribution to speed web interaction with FFMPEG's mostly command-line and sometimes clunky interface. Who knows, maybe you'll build the first real-time transcoding service, I'd be the first to signup as a customer and/or as a contributor to help you on that!
