    9 juillet 2013, par Pasquale C.

    i have a problem.
    I would to do a live streaming with ffmpeg from my webcam.

    1. I launch the ffserver and it works.

    2. From another terminal I launch ffmpeg to stream with this command
      and it works :

      sudo ffmpeg -re -f video4linux2 -i /dev/video0 -fflags nobuffer -an http://localhost:8090/feed1.ffm

    3. In my configuration file I have this stream :

      <stream>
      
Feed feed1.ffm
      
Format webm
      
 NoAudio
      
 VideoCodec libvpx
      
 VideoSize 720x576
      
 VideoFrameRate 25
      
 # Video settings
      
    VideoCodec libvpx
      
    VideoSize 720x576           # Video resolution
      
    VideoFrameRate 25           # Video FPS
      
    AVOptionVideo flags +global_header  # Parameters passed to encoder 
      
                                    # (same as ffmpeg command-line parameters)
      
    AVOptionVideo cpu-used 0
      
    AVOptionVideo qmin 10
      
    AVOptionVideo qmax 42
      
    #AVOptionVideo quality good
      
    PreRoll 5
      
     StartSendOnKey
      
    VideoBitRate 400            # Video bitrate
      
 </stream>

    4. I launch the stream with

      ffplay http://192.168.1.2:8090/test.webm
      It works but I have a delay of 4 seconds and I would to minimize this delay because is essential for my application.
      Thanks

  • Revision 2424ba3d8b : Added a test vector that exercises lpf deltas From frame 2, the lpf deltas are

    17 décembre 2013, par Yaowu Xu

    Changed Paths :
     Modify /test/test-data.sha1


     Modify /test/test.mk


     Modify /test/test_vectors.cc


     Modify /test/test_vectors.h



    Added a test vector that exercises lpf deltas

    From frame 2, the lpf deltas are all cleared for for even frames, and
    a set of values are set and used for odd frames. The intention is to
    exercise decoding code around lpf delta/update decoding.
