• Edit H264 video stream header information ("start_pts" and "start_time")

  27 juin 2020, par David

  I have a video clip that appears to be slightly corrupted. Does not play on VLC but works on Potplayer. I used FFprobe to get information on the video.

  


  The problem appears to be with the start points of the video stream :

  


  time_base=1/90000
start_pts=585050940
start_time=6500.566000
duration_ts=585050940
duration=6500.566000
bit_rate=3123218


  


  I'm just wondering whether it is possible to manually edit the "start_pts" and "start_time" to 0 ? Is there any specific software to do this ? Due to large size of video file, I couldn't load it in Notepad++.

  


  Full ffprobe output shown below :

  15 octobre 2020, par For Fun

  I want to know how I can remove encode settings from the mediainfo with mkvpropedit or ffmpeg ?

  


  İn this post :
How can I remove metadata from a flv file ?
I found this command :

  


  ffmpeg -i INPUT -c copy -bitexact -map_metadata -1 -bsf:v 'filter_units=remove_types=6' OUTPUT


  


  for only h264 AVC !

  


  so how can you do this for h265 HEVC ?
What is exact command do i need to use ?

  


  I want to know how I can do this by just to simply copy -c copy the file ?

  


  İ want to remove this :
