"Подготовка качественных GIF-файлов из видео при помощи FFmpeg" Отправлено Аноним, 18-Май-15 00:23
It is actually quite easy using a videofilter with select. This is quite sensitive to video changes: -vf "select=gt(scene\,0.0098)" whereas this is not so sensitive: -vf "select=gt(scene\,0.3)" EDIT (added your command) so your command would look like: ffmpeg -f video4linux2 -s 800x600 -r 15 -i /dev/video1 -maxrate 800k \ -minrate 1k -bt 800k -bufsize 2M -filter \ drawtext='text=%{localtime }:fontfile=/usr/share/fonts/truetype/DejaVuSans-Bold.ttf'  \ -vf "select=gt(scene\,0.3)" -shortest -c:v libx264 out.mp4 -y P.S. You need to explicitly state the codec libx264 and not just tell it -f h264 and why on earth would you be using avi???
