Resize video using FFmpeg C API
28 février 2012, par cr_azI am trying to resize video file on Android device using FFmpeg. Remark : I cant use FFmpeg as binary - in my case it should be used as shared library (only FFmpeg C API is accessible).
I did not find any documentation regarding video resizing, however it looks like algorithm is following :
10 OPEN video_stream FROM video.mp4
20 READ packet FROM video_stream INTO frame
30 IF frame NOT COMPLETE GOTO 20
40 RESIZE frame
50 WRITE frame TO converted_video.mp4
60 GOTO 20Should I use sws_scale function in order to resize frame ? Is there any other (easier ?) way to resize video file using FFmpeg C API ?
