  • avcodec/motion_est : Attempt to fix "short data segment overflowed" on IA64

    avcodec/motion_est : Attempt to fix "short data segment overflowed" on IA64

    This decreases the MV related encoding table sizes
    
This should have little effect on real world video encoding performance

  • mediastreamvalidator "Error injecting segment data" and Can't deal with multiple sample timings per sample buffer

    14 juin 2018, par Dathan Vance Pattishall

    So using ffmpeg

    /usr/local/bin/ffmpeg -i track.m4a -vn -c:a aac -b:a 192k  -f segment -segment_list 93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.m3u8 -segment_time 120 -segment_format_options movflags=faststart  93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.%03d.m4a

    a playlist file is created where

    #EXTM3U
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-ALLOW-CACHE:YES
    
#EXT-X-TARGETDURATION:121
    
#EXTINF:120.000726,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.000.m4a
    
#EXTINF:119.883175,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.001.m4a
    
#EXT-X-ENDLIST

    Then using mediastreamvalidator I get the following output which leads me to believe there are errors which I have no idea how to fix. I am assuming that ffmpeg is jacking up the segmenting.
