Dear all, I'm capturing an MJPEG stream to a file like this:
ffmpeg -f mjpeg -i http://axis/mjpg/video.mjpg -c:v copy -f mjpeg foo.mjpeg The input stream has a frame rate of 25 FPS. I'd like to drop the output frame rate to 1 frame per second; that is, to write approximately every 25th frame from the input stream to foo.mjpeg. Unfortunately simply adding -r parameter does not work: ffmpeg -f mjpeg -i http://axis/mjpg/video.mjpg -c:v copy -f mjpeg -r 1 foo.mjpeg If I re-encode to e.g. Matroska container like this: ffmpeg -f mjpeg -i http://axis/mjpg/video.mjpg -r 1 foo.mkv I get the desired result, but I'd prefer to avoid re-encoding because of quality degradation. Any suggestions how to do this? Thanks, Petteri. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
