  • ffmpeg to encode MKV or MP4 with segmented Parts in one file

    28 juillet 2014, par Phil

    Is it Possible to create an MP4 or MKV file where the Video, Meta and Audio Data is segmented and placed alternated in a single File ? (By segmented I don’t mean different Video or Audio Tracks.)

    So that it looks like something like this :
    [meta][video][audio][meta][video][audio]…

    I searched for "segmenting", "clustering", and other buzz words. But the most searches ended up in an HTTP-Livestreaming where One File is segmented in single files.
    That Segmenting Technology is okay (so you can stream it). But I don’t want these segments in single Files, i want them to be in one single MKV or MP4 File.

    Maybe someone has any clue.

  • FFmpeg av_read_frame not reading frames properly ?

    16 juin 2019, par Sir DrinksCoffeeALot

    Alright, so I’ve downloaded some raw UHD sequences in .yuv format and encoded them with ffmpeg in .mp4 container (h264 4:4:4, 100% quality, 25fps). When i use ffprobe to find out how many frames are encoded i get 600, so that’s 24 secs of video.

    BUT, when i run those encoded video sequences through av_read_frame i only get like 40-50% of frames processed before av_read_frame returns error code -12. So I’m wild guessing that there are some data packages in middle of the streams which get read by av_read_frame and forces a function to return -12.

    What my questions are, how should i deal with this problem so i can encode full number of frames (600) ? When av_read_frame returns value different from 0 should i av_free_packet and proceed to read next frame ? Since av_read_frame returns values < 0 for error codes, which error code is used for EOF so i can insulate end of file code ?
