  • 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.

  • ffmpeg , copy 1st video "codec info" into 2nd video (change 2nd video codec)

    12 juillet 2016, par Tomer

    I’m having 2 videos.
    1st video is the master, it’s codec info needs to be encoded on the 2nd video.
    Means, 2nd video codec will be same as the 1st one.

    I’m having 15 "1st videos" for "Master" codec info and one file that needs to be converted to the various codecs that each file contain.

    Folder contains those files "1st video" :

    2CIF.h264 , 4CIF.h264 , 5MP.h264 , CIF.H264 , CUSTOM.h264 , CUSTOM2.h264 , 
    
D1.h264 , HD1080.h264 , HD720.h264 , QVGA.h264 , QXGA.h264 , S5020_HD720_15FPS_1Min.mp4 , 
    
SVGA.h264 , UXGA.h264 , VGA.h264

    and the "2nd video" that needs to be converted is : TOM.MP4

    An output of HD720.h264 for example is :

    Input #0, h264, from 'HD720.h264':
    
  Duration: N/A, bitrate: N/A
    
    Stream #0:0: Video: h264 (Main), yuv420p, 1280x720, 25 fps, 25 tbr, 1200k tbn, 50 tbc

    An output of TOM.MP4 is :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'TOM.mp4':
    
    Stream #0:0(eng): Video: h264 (Baseline) (avc1 / 0x31637661), yuv420p, 1280x
    
720, 14013 kb/s, 30.01 fps, 30 tbr, 90k tbn, 180k tbc (default)

    what will be the right way to convert those files ?

    I need to verify those settings ( got them through MediaInfo )
