  • Why container and codec has different time base ?

    19 juillet 2019, par theateist

    I used ffmpeg to get video info. The output is

      Duration: 00:05:57.00, start: 0.000000, bitrate: 611 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 808x610, 609 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc

    The time base is used to somehow(this is also my another question) calculate when to decode and show the frame, right ? So whose time base is used, container (12800) or codec (50) ?

    The another question is why tbn=12800 and not 90000 ?

  • How to do filter twice at different time ffmpeg

    29 décembre 2022, par Мохамед Русланович

    Am trying to implement overlay twice but at different position and different time
Here is what am trying to do :
i just duplicate the filter

    


    ffmpeg -t 50 -y -i film.mp4 -stream_loop -1 -i gif.gif -filter_complex "


[1]colorchannelmixer=aa=1,scale=iw*2:-1[a];[0][a]overlay=x='200':y='300':shortest=1:enable='between(t,0,10)';

[1]colorchannelmixer=aa=1,scale=iw*2:-1[b];[0][b]overlay=x='200':y='300':shortest=1:enable='between(t,15,20)'"  

-acodec copy output_task_3.mp4


    


    But only the first overlay is been implemented, the seconds is not !

    


    how to archive this ?

    


    Now i wrote a PHP script that dose this filter once each time, and repeat proccess then merge all videos, but this is taking so long.
