• Where can I find my output video file after execution of ffmpeg command

  7 août 2019, par Giri Aakula

  I run this command to capture my screen

  ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

  I didn’t find the output.mp4 file anywhere in my HDD. I checked in the bin folder of ffmpeg it is not there.
  I searched the whole PC I didn’t find it anywhere. Can anyone please help me out to find the file.
  The console output is

  C:\Users\USER>ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

• libavformat : add side_data copy in concat demuxer

  15 décembre 2021, par Gerard Sole

  libavformat : add side_data copy in concat demuxer
  Adds support for concat demuxer to copy the side data information
  
  from the input file to the resulting file. It will behave like the
  
  metadata copy, where the metadata of the first file is kept in the
  
  the output file.
  Extract the current code that already performs the stream side_data
  
  copy into a separate method and reuse the method in the concat demuxer.
