Captions are not being displayed

[alive4ever]

Captions aren't being displayed since the timedtext api returns zero length 200 status code for caption requests.

This also affect subtitle download feature of this web app, which got exception because the watch/transcript route doesn't handle zero length response gracefully.

I tested your build recently and caption still doesn't show up.

Hi, thanks for testing my build.

The available build(s) on my repo doesn't have this change integrated.

I've pushed a new test build with all my local changes integrated just now. The latest test release is tagged as v2.8.12-playground14_feature-my-local-changes.

After using your latest build now video doesn't even show up.

UPDATE:
Clean your untracked with 'git clean -f -d -x' and disable 'Use ytcfg for innertube api request' in setting.
thanks for the updated build 👍

Yes, I expected periodic clean up of data directory to be performed.

Please enable discussion tab on your fork, in case people need to ask something.

Done. I've posted first information in my repo.

But this httpx module require more tests with "integrated 360p".

This is a known issue on my end. The integrated stream will only be delivered after fetching whole resources, which take a lot of memory and waiting time.

The recommendation is to turn off prefer_uni_sources settings if using httpx.
