  • -12909 error decoding h264 stream with intra-refresh

    2 juillet 2024, par ciclopez

    I'm making an iOS app that decodes an h264 stream using video-toolbox. I create the stream with ffmpeg on a PC and send it to an iPhone using RTP. It's working nicely when I use this command to create it :

    



    ffmpeg -y -f:v rawvideo -c:v rawvideo -s 1280x720 -pix_fmt bgra -r 30 -an -i - -pix_fmt yuv420p -c:v libx264 -tune zerolatency -preset fast -b:v 5M -refs 1 -g 30 -profile:v high -level 4.1 -f rtp rtp://192.168.1.100:5678


    



    The iPhone receives and displays all the frames. However, when I enable intra-refresh

    



    -intra-refresh 1


    



    decoding fails with error code -12909 (-8969 on simulator) when VTDecompressionSessionDecodeFrame() is called.

    



    I take care of processing UDP packets to extract NAL Units, so I triple checked this process and discarded a problem with this part of the code.

    



    I didn't find any info about Video-toolbox not supporting intra-refresh, so the question is, does Video-toolbox support intra-refresh ? and if it does, am I missing something in the ffmpeg side that makes the stream not supported by Video-toolbox ?
Do I have to add something to the CMVideoFormatDescriptionRef apart from creating it with SPS and PPS data using CMVideoFormatDescriptionCreateFromH264ParameterSets() ?

    


  • AV Foundation or FFmpeg tutorials [closed]

    30 novembre 2012, par time

    I want to edit video on iPhone, so I search and found that there are two ways : AV Foundation and FFmpeg. The problem is that I am unable to find any tutorial to start working with them. Could someone please provide me with some links ?
