Video throttling and/or 403s during playback with Android client about youtube-local HOT 7 CLOSED

I believe it's because both those projects download in 10MB chunks

Here's Invidious: https://github.com/iv-org/invidious/blob/9dfa268204f20b6eba65d3f0977a590e3fbfc120/src/invidious/routes/video_playback.cr#L120 (HTTP_CHUNK_SIZE is 10485760 which is ~10MB)

And here's yt-dlp: https://github.com/yt-dlp/yt-dlp/blob/4d9280c9c853733534dda60486fa949bcca36c9e/yt_dlp/extractor/youtube.py#L3671

Unfortunately I don't really know how to implement this into youtube-local, but I think this is the core of the issue.

Also, you should also pass 'params': '8AEB', in the root of the JSON request, as this lets the Android client play YouTube Stories.

@ImportTaste Current chunk size is 262144 bytes, set in line 116 in server.py if you want to try it. Can't check if it works until tomorrow night

Edit: Those are the TCP chunks, so that would be the wrong value to change. Looking more closely, now I see what you're pointing at is that they split up the single range request into multiple range requests in 10 MB chunks, so we would need to split it up into a for loop like they do.

That seems to be the case. it's beyond my ability to implement, but I hope I was of some help regardless.

It appears that's not the issue. As it is, video file requests using av-merge.js already split the requests into small range requests. Additionally, I ran an experiment where I inserted urls from yt-dlp into youtube-local, and the video played fine without 403s, so something is wrong with the URLs themselves. Looking into it

The params was the problem, thanks for pointing that out. Latest release fixes it

There's an age-restricted video that is exhibiting the same throttling behavior that I experienced with this issue. Is it related to #146?

Yes, because for those it uses the TVHTML5_SIMPLY_EMBEDDED_PLAYER client instead of the ANDROID client. Android doesn't require decryption. TV embedded does, and one encryption thing is that nsig which causes the video to be throttled
