  • DirectShow RTSP SourceFilter with MPEG-4 Video Stream

    5 octobre 2011, par 6.45.Vapuru

    I create a simple direct show source filter using FFmpeg.I read rtp packets from RTSP source and give them to decoder. It works for h264 stream.

    MyRtspSourceFilter[H264 Stream] ---> h264 Decoder --> Video Renderer

    The bad news is that it does not work for MPEG-4. I can able to connect my rtsp source filter with MPEG-Decoder. I got no exception but video renderer does not show anything. Actually just show one frame then nothing [just stop]... Decoders and Renderers are 3rd party so i can not debug them.

    MyRtspSourceFilter[MP4 Stream] ---> MPEG-4 Decoder --> Video Renderer

    I can able to get rtp packets from MPEG-4 RTSP Source using FFmpeg sucessfully.There is no problem with it.

    It seems that i have not set something(?) in my Rtsps Source
    Filter which is not necessary for H264 stream but may be important for
    MPEG-4 stream

    What may cause this h264 stream and MPEG-4 stream difference in a direct show rtsp source filter ? Any ideas.

    More Info :

    — First i try some other rtsp source filters for MPEG-4 Stream...Although my rtsp source is same i see different subtypes in their pin connections.

    — Secondly i realy get suspicious if the source is really MPEG-4 SO i check with FFmpeg...FFmpeg gives the source codec id as "CODEC_ID_MPEG4".

    Update :
    [ Hack ]

    I just set m_bmpInfo.biCompression = DWORD('xvid') it just worked fine...But it is static. How to dynamically get/determine this value using ffmpeg or other ways...
