Proposal

Hello, I'm interested in knowing if it would be possible to support custom video codecs on Android.

Uses cases

To allow developers to have more control in what format a video is saved so they can optimize for their use case a bit better.

(In my case, it would be important to only use mpeg4 even tho it it's not the most efficient, due to the legal stuff with h264 en & decoders)

Thoughtprocess

I tried to go through your native code and figure out if it would be possible. Sadly, I have 0 experience in native development...

From what I've gathered, it seems to be possible on the iOS side, you already seem to support some. However, on Android, it seems to be more difficult since CameraX doesn't support codec specifications if I understood it correctly.

I would be interested in trying to help implement that if you think it can be done.

(I'll add doc links I found later, I'm currently on mobile)
