    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

  • libav :0: : cabac decode of qscale diff failed at 4 26 ? While UDP Streaming in Gstreamer

    28 juin 2016, par Prasanth Kumar Arisetti

    I would like to stream the webcam data over UDP in mpegts format.

    At Sending End: :

    gst-launch-1.0 -v v4l2src device=/dev/video1 ! videoconvert ! video/x-raw,width=720,height=576,framerate=25/1,format=I420 ! videoparse width=720 height=576 framerate=25/1 ! x264enc bitrate=2048 ref=4 key-int-max=20 byte-stream=true tune=zerolatency speed-preset=3 sliced-threads=true threads=4  ! video/x-h264,stream-format=byte-stream,profile=main ! queue ! mpegtsmux ! rtpmp2tpay ! udpsink host=192.168.2.149 port=8888 sync=true async=false qos=true qos-dscp=46

    At Receiving End: :

    GST_DEBUG=4 gst-launch-1.0 -v udpsrc port=8888 caps=application/x-rtp,media=video,encoding-name=MP2T buffer-size=524288 ! rtpmp2tdepay ! tsdemux name=demuxer  demuxer. !  queue max-size-buffers=0 max-size-time=0 ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink qos=true sync=true async=false

    For few seconds, video is coming good, but after that it is getting disturbed, and not at all coming, struck at single frame.

    And when i used GST_DEBUG=4, i observed below error :

    0:00.000000000, position 0:00:10.397114020, duration 99:99:99.999999999

    But, if I stream the Data to localhost, then it is perfectly working.

    After setting cabac=false on x264enc,

    0:00.000000000, position 0:00:14.796602703, duration 99:99:99.999999999

    What is the problem here ? is this because of network bandwidth or any other else ? And how to solve this problem ?
