Expected Behavior
If possible, remuxed HEVC recordings in OBS made with the hardware encoder should use hvc1 so as to be usable by system software directly after remuxing.
Current Behavior
Currently, remuxed HEVC recordings in OBS must be retagged with e.g. ffmpeg as hvc1 before built-in software (QuickTime, Final Cut, etc.) can open them.
Steps to Reproduce
Any remuxed recording made with the VT HEVC Hardware Encoder in OBS has this issue.
Anything else we should know?
Filed at Pat's request over at https://github.com/obsproject/obs-studio/pull/7010 .
Making remuxing use hvc1 for HEVC by default should work (since at this time you're not supposed to record to MP4 directly anyway).
Right now the tag is just set to 0: https://github.com/obsproject/obs-studio/blob/12d1f1c3358f7231244db0b971a333445e346f80/libobs/media-io/media-remux.c#L152-L154
Hi there,
This issue was solved over a year ago, but somehow, I still have it in OBS 30.0.2 for Windows (the latest version as of today). I do recordings in HEVC using NVENC, and it works fine, except I can't play the video stream with QuickTime on my Mac.
I tried adding the "hvc1" tag with ffmpeg, and it worked, so I suppose this is the same issue.
Just in case, here are my OBS settings:
Thanks,
Denis
