  • lavd/v4l2 : do not fail when VIDIOC_ENUMSTD returns ENODATA

    18 août 2014, par Andre Wolokita
    lavd/v4l2 : do not fail when VIDIOC_ENUMSTD returns ENODATA

    As of September 14 2012, v4l_enumstd() will return ENODATA
    
when a device’s std field is set to 0. That is, the device
    
does not have a standard format. In order to properly
    
handle this case, v4l2_set_parameters should catch the
    
ENODATA code and break instead of failing.
    

    Below is the v4l2-core commit describing this change.

  • avcodec_decode_video2 returns positive number when got_picture_ptr is 0

    22 août 2017, par dafnahaktana

    According to the documentation : here, avcodec_decode_video2 should return 0 if no frame could be decompressed. The got_picture_ptr should also be set to zero if no frame could be decompressed.

    I ran this function on a h264 video and I got positive return value while the got_picture_ptr was set to 0. Maybe that the documentation is not updated ?

  • NAL Type STAP-A and retrieve the sps and pops

    2 mars 2016, par H. BY

    I wrote a RTP server to receive the RTP packets which are sent by command ffmpeg -i test.mp4 rtp rtp ://ip:port (client) and the server could get the nal type 24 (STAP-A).
    And I want to use the server to retrieve the spa and pps from the first nal(type 24) instead of info from ffmpeg command.
    Is it possible SPS and PPS would be aggregated in one nal ?

    for example

    [RTP header][nal header(type 24)][nal1 header][nal1 size][nal1 payload][nal2 header][nal2 size][nal2 payload]...

    thanks
