  • ffmpeg concat videos with different timebase

    2 août 2019, par Kris Roofe

    I use

    ffmpeg.exe -f concat -i file_path_list_txt -c copy out_out.mp4

    to concat

    for file in 1265_*; do ffmpeg -i $file -crf 30 -b:a 23k -b:v 96k -threads 3 -y 'out_'$file; done

    compressed video.

    When I play the generated video, the player shows the video length is much longer than the sum of compressed video pieces. And at the linkage between slices,the frame can play a very long time,time on the player is going on,but the frame is still.

    I use ffprobe to show the original video pieces and compressed video pieces. And found the original videos with same tbr,tbn,tbc, while the compressed not.

    Original videos :

    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, progressive), 1600x1144, 134 kb/s, 8.17 fps, 600 tbr, 600 tbn, 1200 tbc (default)
    
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, progressive), 1600x1144, 138 kb/s, 9.73 fps, 600 tbr, 600 tbn, 1200 tbc (default)

    Compressed videos :

    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1600x1144, 174 kb/s, 8.17 fps, 8.17 tbr, 245050 tbn, 16.33 tbc (default)
    
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1600x1144, 127 kb/s, 9.73 fps, 9.73 tbr, 1750800 tbn, 19.45 tbc (default)

    And when I concat, in the console,ffmpeg show below info :

    [mp4 @ 000001fe0193b700] Application provided duration: 2585263321 / timestamp: 6303355764 is out of range for mov/mp4 format
    
[mp4 @ 000001fe0193b700] pts has no value
    
[mp4 @ 000001fe0193b700] Application provided duration: 2585443321 / timestamp: 6303535765 is out of range for mov/mp4 format
    
[mp4 @ 000001fe0193b700] pts has no value

    In my situation the video pieces are generated time by time, and I don’t know when it stops, so I cannot do concat before compress. Each time a video piece generated I comress it and append it.
