PeerTube v3.1.0-rc.1

Describe the problem to be solved
I'm trying to transcoding vp9+opus or vp9+flac in one video, but peertube default not use -strict experimental, it's cause error exception on ffmpeg v4.2.x

Describe the solution you would like:
Add -strict experimental when peertube make m3u8 file command.

hi @meredith2u,

Could you show us your custom transcoding profile definition? Could you show us your error? Could you explain why adding -strict experimental would solve your problem?

Per our deps documentation:

only LTS versions of external dependencies are supported. If no LTS version matching the version constraint is available, only release versions are supported.

Ffmpeg's latest release is 4.3.2. Please upgrade first.

In FFmpeg 4.2.x transcoding opus into mp4 format required command -strict experimental
So, I add command in config, then FFmpeg success doing transcoding job, then peertube next step is make m3u8, in that time, FFmpeg showing error message, I think that peertube when make m3u8 command may not include -strict experimental.

In FFmpeg 4.3.x transcoding flac into mp4 format will showing same type of exception.
