• tag 0x34363278/'x264' is not supported with codec id 28 and format 'mp4 / MP4 (MPEG-4 Part 14)'

  9 septembre 2017, par Recep şen

  I am trying to read a video from .mp4 file and write into new .mp4 file but it gives me this error after I run :

  OpenCV : FFMPEG : tag 0x34363278/’x264’ is not supported with codec id
  28 and format ’mp4 / MP4 (MPEG-4 Part 14)’

  OpenCV : FFMPEG : fallback to use tag 0x00000021/’ !???’

• flutter_ffmpeg - Can we trim a part of the video in flutter while recording

  16 février 2021, par Mayur Agarwal

  I am making a flutter app, in which a user can record a video and pause in between, and when the user pauses the video a clip is formed.
So if the 4 clips are there, then 4th clip can be removed from the video (according to the time of the last clip).
By a clip I just mean the time interval between two continuous pauses. The video is being recorded continuously.
There's a way to trim a video after it's being record, for example,

  


   ffmpeg -ss 00:01:00 -i input.mp4 -to 00:02:00 -c copy output.mp4


  


  But I think it's possible only when the video is recorded.

  


  So, Is there any way to to trim a video (using flutter_ffmpeg) or the last clip, while the recording is paused ?
