I want to stream a video over my local network (a wireless router setup),
I followed the steps at http://www.howtogeek.com/118075/how-to-stream-videos-and-music-over-the-network-using-vlc/
But the client is not able to open the video file
Giving the error -
No suitable decoder module:
VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this.
Even on the same machine, sometimes i get the same error and sometimes it plays
I am not able to understand what am i missing :P
EDIT: I am using a .mp4 file as source, and the generated string is
:sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:http{mux=ffmpeg{mux=flv},dst=:8080/} :sout-keep
On the Destination Setup -> Transcoding page the profile selected by default says Video - H.264 + MP3 (MP4).
Click the Edit selected profile button, go to the Audio codec tab and change the Codec option to either MP3 or MPEG 4 Audio (AAC).
This should help avoiding the unknown codec error.

I want to play the video simultaneously while it is downloading via unitywebrequest. Will AVPro video support this? If so please provide me some guidance, as i am new to unity and avpro video. I can able to play the video which is downloaded fully through FullscreenVideo.prefab in AVPro demo. Any help will be much appreciated.
There are two main options you could use for displaying the video while it is still downloading.
Through livestream
You can stream a video to AVPro video using the "absolute path or URL" option on the media player component, then linking this to a stream in rtsp, MPEG-DASH, HLS, or HTTP progressive streaming format. Depending on what platforms you will be targeting some of these options will work better than others
A table of which file format supports what platform can be found in the AVProVideo Usermanual that is included with AVProVideo from page 12 and onwards.
If you want to use streaming you also need to set the "internet access" option to "required" in the player settings, as a video cannot stream without internet access.
A video that is being streamed will automatically start/resume playing when enough video is buffered.
This does however require a constant internet connection which may not be ideal if you're targeting mobile devices, or unnecessary if you're planning to play videos in a loop.
HLS m3u8
HTTP Live Streaming (HLS) works by cutting the overall stream into shorter, manageable hunks of data. These chunks will then get downloaded in sequence regardless of how long the stream is. m3u8 is a file format that works with playlists that keeps information on the location of multiple media files instead of an entire video, this can then be fed into a HLS player that will play the small media files in sequence as dictated in the m3u8 file.
using this method is usefull if you're planning to play smaller videos on repeat as the user will only have to download each chunk of the video once, which you can then store for later use.
You can also make these chunks of video as long or short as you want, and set a buffer of how many chunks you want to have pre-loaded. if for example you set the chunk size to 5 seconds, with a buffer of 5 videos the only loading time you'll have is when loading the first 25 seconds of the video. once these first 5 chunks are loaded it will start playing the video and load the rest of the chunks in the background, without interrupting the video (given your internet speed can handle it)
a con to this would be that you have to convert all your videos to m3u8 yourself. a tool such as FFMPEG can help with this though.

I have an HDMI source connected to a Chinese HD HDMI Encoder box. Playback to VLC on my PC works (open network stream http://192.168.0.150:80/hdmi)
Stream is NOT leaving my local network (on purpose)
I cannot get a signal to display on my Google Nexus Player or my NVidia Shield via Cumulus TV app. (The point being to integrate the feed into the Google Live Channels app) I have tried adjusting several of the settings to no avail. Should I be trying a specific format? I tried the Fiddler (didn't see anything descriptive in that tool) but still have no definitive answers. I am pretty sure this device only produces a H.264 bitstream, which works in the PC version of VLC, but I have no luck on my androidTV devices (to include VLC). I can also get playback on my android PHONE in VLC...
seeking help/ troubleshooting advice...
main stream settings are:
H.264 Level： high profile Encoding frame rate： 30[5-30]
Bitrate control：vbr Key interval： 30[5-200]
Encoded size： auto MinQp： 3[1-51] MaxQp： 32[MinQp-51]
MaxBitrate： 8000[16-12000]
Audio bitrate：192000 Audio channel：L+R
Audio Codec：AAC Resample：Disable Package：B HTTP： Enable /hdmi (begin with "/")
HTTP Port：80[1-65535] Change TS ID：Disable
transport_stream_id： 300[256-3800]pmt_start_pid： 480[256-3800]
stream_start_pid： 481[256-3800]RTSP： Disable Multicast IP： Disable
RTMP server ip： Disable ONVIF：Disable Enable
It looks like your encoder can stream three different formats:
Http - probably HLS
RTMP
RTP/RTSP
Now the question is which formats do your clients support and is the format on the above list.
You could install Fiddler on your PC (web app debugger) to verify that your streaming box actually serves HLS.
Since you know that VLC plays your stream you could try to install VLC on your Google Nexus player: https://play.google.com/store/apps/details?id=org.videolan.vlc
Hello All I have been working on a project for a while:
I have a non standard MP4 video file I want to play off a server in a IPhone App (I am using Flash builder to create it).
Due to a combination of server problems (not correctly identifying MIME type and cant be changed) and IPhone limitations (e.g. not being able to force the iplayer to play files with wrong extension), I have had to setup a process that reads the file in, saves it locally and then point the video player at the local file.
Although this sort of works, i am having an issue with some of the files that are large (94mb for a 17 min video) and a slow server - which takes 120 seconds to transfer the whole file.
I thought that if you started playing the video, then the transfer rate would be faster than the playback rate so the video would play ok.
However sometimes the video just crashes, which i am guessing is a result of the video reading beyond what has been written.
If the video played the internal file using progressive download I think it would probably not crash but resume once more date had been read but understand that progressive download is triggered by a url extension beginning with HTTP://
Can you make an internal file play using progressive download ? I know this would not normally be expected as logically the system would expect a local file to already be download ?
Any help appreciated
Thanks
Toby
try this to know download file is complete or not
HCDownload
it is very easy to use only write its delegate method.

I am using Flash Media server 4.5 and i read the tutorial if i want to stream the live feed, i may need to use the media live encoder. but what i found in media encoder is i have to manually setup everything and it only support camera devices.
But in my case i have multiple video files keep received from another program, my goal is use the Flash Media server to perform a live boardcasting with these video file one by one.
That means when client watching the streaming, they will not notice the server is play mov1, then mov2, then mov4, then mov5... and so on.
Also can FMS dynamically create a new streaming session (invoke by code), so that when client A uploading some video files to the server, the FMS open a new streaming session only stream cilent A video files?
Can FMS achieve such purposes? any tutorial provided would be very helpful!
Edit for Open Bounty
I want to basically deliver a live stream of video where a list of videos are source. I am currently using Flash Media Server with Cloudfront CDN to deliver content. So if I have video1, video2, and video3. I want to play them back to back as a live stream (so no skipping ahead in video), is it possible to do this? Bounty goes to clever workaround. Think of this as a television channel.
i have been working on the live streaming technologies for the past 1and half year . There is no option in flash live encoder for any file encoding.
1.To encoder your file you can use your dvd player devices or some thing else which supports usb devices playback options.and use the dvd player output to broadcast using flash media live encoder.
2.And the another set is to setup windows media encoder that supports file encoding(no need od dvd player) but it supports only windows media services.
At present i live webcast video file in this way only for my company http://www.malar.tv/live.php
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.
