Part Number: AM5728

Tool/software: Linux

Hi

  I am in the development board to execute the following order to the network to send rtp package

   root@am57xx-evm:# gst-launch-1.0 -v -e videotestsrc  ! 'video/x-raw,width=1280,height=720,framerate=30/1' ! queue ! ducatih264enc ! queue ! h264parse ! queue ! rtph264pay ! queue ! udpsink host=192.168.0.42 port=5000

    Hello,

    The pipeline that you are using, it seems  you are streaming elementary stream.
    You could try to mux the stream before sending it.

    Please check these links regarding VLC and playing h264 elementary stream:
    reolink.com/.../
    forum.videolan.org/viewtopic.php
    You could search for more how h264 elementary stream could be played via VLC as well.

    Hello：
    Can you provide an example of capture + h264 encoding + RTSP send?

    TI__Guru* 80190 points
    Hello,

    Have you tried to add mux element?
    The pipeline will be something like :

    .........h264parse ! queue ! qtmux ! udpsink host=192.168.0.42 port=5000

    Please check this guide there are example pipelines:
    processors.wiki.ti.com/.../Processor_Training:_Multimedia

    Also check this link it could be helpful there is an example capture -> streaming, capture->save in the file and live preview and the same time.

    So I do not know whether the error is from my sending command or vlc receiving command?

    Hello,

    Could you try to ping PC->board and board->PC.
    If you are using udpsink in gstreamer pipeline could you try :
    vlc -vvv udp://ip:port

    On your board it seems that gstreamer is running:

    Hello,

    In additional you could try to receive the video stream by using gstreamer on PC side instead of VLC.

    Hello:
    Can you provide a detailed gstreamer command on PC side instead of VLC?

    Hello,

    I am sorry for the delay.

    This depends on what is the gstreamer version that you have on PC.

    In case that you have installed gstreamer version 0.10 you could try with:
    gst-launch-0.10 udpsrc port=5000 ! 'application/x-rtp, media=(string)video, clock-rate=(int)90000, payload=(int)96' ! rtph264depay ! ffdec_h264 ! xvimagesink sync=false

    In case of gstreamer version 1.0:
    gst-launch-1.0 udpsrc port=5000 ! 'application/x-rtp, media=(string)video, clock-rate=(int)90000, payload=(int)96' ! rtph264depay ! avdec_h264 ! xvimagesink sync=false

    In both cases the video that you are streaming is mux in some format you should add demuxer in the pipeline on PC side.

    The pipelines above should decode elementary stream(the pipeline in your first post).

    Hope this helps.
