  • ffmpeg rotate and trim video 4k horizontal -> 2k vertical

    19 juillet 2015, par Flash Thunder

    I was looking for solution, but seems that the ones that google finds are not valid anymore... I think that you have to use mapping for that, but not sure how...

    I need to rotate horizontal 4K video and trim it (leaving center part), so the output would be vertical 1080p. Could anybody give me a hand with that ?

    Of course I need to keep the best possible quality.

    PS. ffmpeg compiled from git-8250943 (2015-07-17)

  • Attach file to mp4 video with ffmpeg

    9 mai 2017, par Bird

    I’m trying to attach or embed a kml file to a mp4 video ; or, I’m trying to find out if this is possible at all. Based on the wikipedia page on video containers, it looks like mp4 containers support file attachments, so theoretically it seems possible.

    I’ve tried this command :

    ffmpeg -i input.mp4 -attach site1.kml -metadata:s:t:0 mimetype=application/vnd.google-earth.kml+xml output.mp4

    which returned :

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted  

    If I change the output file to output.mkv it works (based on this question), but I’d really like to maintain the mp4 container.

    Edit : I’ve figured out a way to parse a kml file into a srt subtitles file and embed that in the mp4 container, then extract and recreate the kml all using Python. But, it would be much cleaner to just attach the kml.

    Anyone know if this is possible ?

  • Extract Less Keyframes (ffmpeg)

    6 juillet 2019, par Barnee

    I’m trying to extract keyframes from a large video I have. The problem I’m seeing is that it is extracting far too many, leaving me with many very similar images.

    Below is what I am currently using (from terminal)

    ffmpeg -i video.mov -vf "select=eq(pict_type\,I)" -vsync vfr thumb%04d.png -hide_banner

    What would be great is if there was a way I can either make it only output 1 in 5 keyframes. Or what would be even better is if there is a way I can make it only output if the frame is over x% different from the previous one.
