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 !
