403 error on most video downloads

[AlexanderBooth84]

I'm trying to download 1080p videos using the latest release but it seems to silently fail falling back to the 360p version no matter what settings I use.

Using the video_test.js example with no config changes but adding some console logging to the failed function in dl.js I'm seeing:

dl: failed - vformat=0, aformat=0 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=0, aformat=1 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=0, aformat=2 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=0, aformat=3 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=0, aformat=4 { msg: { msg: 'failed', fail: 'video', reason: 403 } }
dl: failed - vformat=1, aformat=0 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=1, aformat=1 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=1, aformat=2 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=1, aformat=3 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=1, aformat=4 { msg: { msg: 'failed', fail: 'video', reason: 403 } }
dl: failed - vformat=2, aformat=0 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=2, aformat=1 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=2, aformat=2 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=2, aformat=3 { msg: { msg: 'failed', fail: 'audio', reason: 403 } }
dl: failed - vformat=2, aformat=4 { msg: { msg: 'failed', fail: 'video', reason: 403 } }

I can't see how the recent changes would cause this so perhaps something has changed at the YT end?

Hi. Yes, another barrier from Youtube. There is a work around to this by spoofing an alternative client to the standard web client. I will push a PR soon.

PR #66 published. Worked when testing. Let me know if it helps.

The video downloads seem to work ok but only if you use a cookie and user-agent.

However the search functionality seems to be broken.

You can see this with the example application that yields the following.

Around the end of last month, Youtube started making it increasingly necessary to have a logged-in cookie to access video info. It is not a problem unique to ytcog.

As for search, there are quite a lot of similar problems in this project that I will patch shortly in v2.6

In the meantime, I am working on a new innertube project that will eventually replace this project.

Thanks for the update. Your efforts are much appreciated. Great project.
