Free software is not necessarily free. Even when the sources are released under a free software license (such as GPL), the compiled versions can be charged. But anyone is free to get the sources and compile them. That said, MakeMKV is not a free software, and it is only partly open-source. It's a freeware (for the DVD rip/decrypt part) and a shareware (for the bluray rip/decrypt part). Thanks for correcting me on MakeMKV being only partially open-source, pehache.

[FFmpeg-user] Can v360 use cuda or GPU
I found conflicting info on the web and couldn't understand the source. Does v360 utilize GPU (cuda) ? My test with just adding '-hwaccel cuda' to a -filter_complex (hstack and v360) chain does not throw error and shows ffmpeg on GPU, but the speed is same as using CPU. ___ 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] Handling alternating stream title and similar metadata
Some audio streams may have StreamTitle metadata that will change from time to time. How do you record that changing information so that you can later show the title when the recording is being played? Are there some standard tags that can be used to denote e.g. current program name or current song name? Can they be used with different output file formats such as Opus?

I do not see what is the use of using -copyts, if that resets the timestamps anyway with -start_at_zero.
