• Dynamic Location Offsetting while Desktop Video Capture in FFMPEG [closed]

  18 février 2024, par Zen Of Kursat

  Is there a way to dynamically change offsets during screen capture ?

  


  But these offset values are static (eg. 66 and 77) and we cannot change these values during video recording. Simply, I am trying to record screen with according to mouse coordinates which are of sure changing while video recording starts.

  


  For example :

  


  ffmpeg -f gdigrab -framerate 30 -offset_x 77 -offset_y 66 
       -video_size 1920x1080 -i desktop output.mp4

  This error caused the compilation to stop after line 53

  


  How can I set up to avoid this compilation error

  


• Importing sub module of FFmpeg in Android

  3 mars 2024, par M. Usman Khan

  I was able to import the "full" module of FFmpeg library in Android like this :

  


  api 'com.arthenica:ffmpeg-kit-full:6.0-2'


  


  But this was adding about 90mb to my app. So I tried to import only "min-gpl" like

  


  api 'com.arthenica:ffmpeg-kit-min-gpl:6.0-2'


  


  But instead of decreasing, this actually increased my app size further (about 100mb).

  


  Am I not doing it right ?
