Can we revise this to also better accommodate audio?

Leaning towards Volume Normalised aac 256k for stereo using this tool: https://github.com/slhck/ffmpeg-normalize
almost like a 'default' approach to stereo implementation of any video file (ultimate fallback). Yes this might modify audio that doesn't require it, but in the interest of compatibility, this hammer smashing approach might just be okay. (It's not as necessary as video to preserve quality IMO).

Honestly though, after thinking about this, as much as we might be able to 'game the system' with a third party streamer such as Plex, we are walking on tricky territory.

e.g. I'm really starting to think I need more control over something like hls or mpeg dash AND control over the media player decision making process. From what I have gathered, it might be possible to store multiple audio streams under the same mp4, set all disposition to none (no default audio streams) and rely on Plex to decide upon the 'audio stream that requires less transcoding'.

But honestly, I would much rather disable partial transcoding all together in order to properly debug something like this more easily.

But again, it comes back to the decision making done by the streamer... I need to more control. So this is why such a blunt force is being used atm (convert ALL to aac 256k volume normalised stereo)...

Essentially, this is where Plex fails imo. I need more control and I'm not going to force files in a way to adhere to stupid rules, where you still have to heavily rely on end user settings (of which you have no control over, they could change, mess up!)

So we will go with the All In AAC convert rule and call it a day as far as audio is concerned.

We would really need our own streaming app to really push the limits here properly.

Here is a condensed version that ignores h264 10 bit candidates and transforms. Honestly starting to think this is best to avoid confusion at this stage. I don't really think many devices that can ONLY support h264, will support h264 10 bit HDR. I could be wrong, but it might just be best to leave such scenarios for better capable processors and more appropriate codecs (hevc etc.)

**CURRENTLY ASSUMING SINGLE VIDEO STREAM AND SINGLE AUDIO STREAM PER VIDEO CONTAINER (no multiple audio streams, no alternative language audio streams, no subtitles)
