[Libav-user] How to changes resolution to output file.

[ABDALLAH Moussa]

Hello,

I am trying to record a stream video to a output file mkv. I set my camera with the resolution 1280x720 and I would like to change it with ffmpeg on my program how can I do that please ?

I have success to change the framerate but I failed  with the resolution or other option like bit_rate :

        ivst->r_frame_rate.num=25;
        ivst->r_frame_rate.den=1;
        ovst->r_frame_rate      = ivst->r_frame_rate;
        ovst->avg_frame_rate    = ovst->r_frame_rate;
        ivst->codec->bit_rate = 3000000;
        ovst->codec->bit_rate = 3000000;
        ivst->codec->height = 320;
        ivst->codec->width = 240;
        ovst->codec->height = 320;
        ovst->codec->width = 240;

Thanks you for your help !
