  • ffmpeg ffserver - create a mosaic from two 720p webcam feeds

    28 juillet 2015, par der_felix

    for a project i would like to take the video feeds (NO audio) of two logitech c920 webcams, put them side-by-side and stream them.
    the c920 is able to compress the video feed with h264 itself(if enabled) and delivers 1080p with upto 30fps.
    the stream is then loaded in an android app by a ffmpeg library and rendered to the screen.

    what i already know :
    i know that i can take multiple streams or input files and create a mosaic stream via the filter_complex module.
    http and h264 seem to be good for streaming, but other configurations are also welcom if they are faster/better.

    the question :
    but how can i start the cameras with v4l2, set the camera resoltution and camera internal encoding and use these streams to create the mosaic ?
    the mosaic should be unscaled (=2560x720px).

    and i very often get the error code 256 but didnt find a solution what it means.

    the system : laptop with usb3, ubuntu 15.04x64 ffmpeg 2.7.1 and ffserver 2.5.7

    thanks for your help

  • Is there a media server which just receives any rtsp streams and serves them ?

    7 mai 2015, par Given92

    I have some rtmp streams served over nginx-rtmp-module and the number of them will be changed dynamically.

    But for the limit of client, I have to serve them in rtsp protocol. Obviously, It’s not supported by nginx-rtmp-module. So I plan to run a rtsp server in the same device, and convert the rtmp stream into rtsp stream with ffmpeg, then send the rtsp stream to the rtsp server. So that client could play the stream from the rtsp server.

    The trouble is that I could not found a stable server which just receive any rtsp streams and serve them.

    There is an example that fits all my need but it’s a little unstable.

    I run it in verbose mode and send stream with :

    ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>
    </name></name>

    and play the stream with :

    gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>
    </name></server>

    The video does not appear and there are some repeated warnning like this :

    WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.
    Additional debug info:

    When I try :

    gst-launch-1.0 playbin uri=rtsp://<server>/<name>
    </name></server>

    it is stuck and no video appear :
