 |
|
Hi,
is there a way to use ffmpeg to split a video file into chunks of given file size? I have a lot of big .mkv files and I need to turn them into .mp4 files no bigger than 4GB. ffmpeg takes care of remuxing, but I'd like to also split them in one step. Currently I use mkvmerge to split them first and then remux with ffmpeg, which takes twice as long time as it needs. Any ideas? |

| Code: | | ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi |
That's the way to split by timings, don't know if there's a way to do it by size. From there, should be possible to adept it to a single step.
