Support copy codecs in peertube runner

[ilfarpro]

Describe the current behavior

I'm sorry. this could be not a bug or maybe just not implemented yet...

When I use Peertube without runner it can do job optimize-to-web-video and next to it new-resolution-to-hls job with "copyCodecs": true option. Peertube runner can't do that for some reason. It leads to significant increase in time because runner should encode original resolution 2 times:

1. to optimize video to web (highest resolution)
2. encode highest resolution again

Please take a look at screenshosts to see more.

This is how Peertube without runner behaves. It can copy codecs and save a ton of time.

But Peertube runner encodes 2 times the same resolution and it takes 2x time.

Maybe it's related to this line of code.

PeerTube/apps/peertube-runner/src/server/process/shared/process-vod.ts

Line 118 in da992cb

copyCodecs: false,

Steps to reproduce

1. Install latest peertube runner
2. Uload a video
3. Transcode that video :)

Describe the expected behavior

I expect peertube runner to copy codecs for highest resolution when it does it's HLS version. Peertube already can do that, let's make runner be able to do it too, please 🙏
