  • Resize video using FFmpeg C API

    28 février 2012, par cr_az

    I 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 20

    Should I use sws_scale function in order to resize frame ? Is there any other (easier ?) way to resize video file using FFmpeg C API ?
