Error 702 with AV1 HDR10+ Content for MKV (The case for upgrading ffmpeg)

[MrGrackle]

Wonderful! After 3 years of my manually updating files every week, I may not have to do it anymore if the dev can get in the habit of doing it. Much appreciated.

Also, we need an updated YoutubeToMP3Process.exe every week using the latest YT-DLP nightly source (preferred) or the most recently released stable.
Others that need updating are MediaInfo, Shaka-packager, Aria2c, and Atomic Parsley. And while you're at it, update CEF (Chromium) every time a new version comes out.

As for mp4box, I lost interest in it after it was found to be causing 702 errors. Perhaps take a look again at Bento4? SF used to use it. I'm not a developer, so, I'm not aware of the advantages of either program compared to the other.

Yeah, yt-dlp needs to be updated more often, not after it has already been obsoleted by new code.
Is Bento4 a completely different program? I notice Peacock downloads always show the Bento handler.
I too would be leery of mp4box getting updated. They would obviously have to do it right. If it come out on a Thursday update I would steer the hell away.
