Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Thank you for that. It worked perfectly. And thank you for the book - it looks like there's realms of good stuff in it. Looks like a text book to me.. probably won't be able to read it but will have to dip in and out of it to find things when I need them. Congratulations on it... wish I'd achieved something like that... :) Don't understand your batch file either, though I used to write DOS batch files all the time back then in the day... I think the command set and syntax maybe have changed a bit anyway thanks very much... :) - Remember Brandolini's Law and look around.

Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Personally I tend to do this sort of thing with JScript on Windows. It's not the loveliest interpreter, but then at least you have something approaching a real programming language to do all your string manipulation!

Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Michael, you could use this: %~ni <- this means the filename without the extension, so instead of renaming, just use: ffmpeg -i %1 -y %~n1 or ffmpeg -i %1 -y -c copy %~n1 On Mon, Oct 21, 2019 at 10:28 AM Michael Koch wrote: > > > > > set OUT=%IN:mkv=mp4% > > please note that this renaming will give unexpected results if "mkv" is > also part of the filename, for example > aamkv.mkv will be renamed to > aamp4.mp4 > > If someone knows a solution to this problem, please let us know. > > Michael > ___ > ffmpeg-user mailing list > ffmpeg-user@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-user > > To unsubscribe, visit link above, or email > ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe". ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-user] How to use ffmpeg in batch mode?
set OUT=%IN:mkv=mp4% please note that this renaming will give unexpected results if "mkv" is also part of the filename, for example aamkv.mkv will be renamed to aamp4.mp4 If someone knows a solution to this problem, please let us know.

Hi. If you are only changing the container and don't want to transcode the contents, be sure to add -c copy in the ffmpeg line of the example (haven't tested it but it seems fine), so it looks like this: ffmpeg -i %IN% -y -c copy %OUT% Br.
