Re: [FFmpeg-user] All the video captures are made at a resolution of 176x144

I already achieved it after a little research, using this command: ffmpeg -f video4linux2 -input_format h264 -video_size 1280x720 -i /dev/video0 -vframes 1 -f mjpeg menu%d.jpg ffmpeg version 3.4.1-1+b2 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7 (Debian 7.2.0-19)
