Thanks a lot for the PR! I do like the idea of and the changes you've made regarding consolidating the code. I have a few comments though:
-
When recording "System Audio", the microphone track will be included. This doesn't make much sense in my opinion, but maybe there are scenarios where you'd want both of those? This was avoided when using a separate audio-specific file writer; I think you could probably just check
if recordMic && !audioOnlyininitMedia()here instead -
I think there's a bug in here, as recording (sometimes..? I think it was working at first but now it consistently) causes a crash
Edit: This appears to have been an issue with my code, sorry! -
See my comment about the file format 👍

This actually doesn't work! While the file ending appears correct, the actual format in the file will be wrong. (So, for example, when recording Opus, you'll get a file with an AAC stream in a file named .ogg)

No worries at all! Likewise, happy new year :)

use a single AVAssetWriter to write both audio and video so that we can capture the mic in both scenarios.
