I've seen the same error, but it appears at random. Looking in main.py where the exception occurs, when I examine self.vid_info, playabilityStatus shows status = "ERROR" and reason = "This video is unavailable".

[Cortlando]

So I checked what happens when I run my script and I also see that in self.vid_info, playabilityStatus shows status = "ERROR" and reason = "This video is unavailable". I took the same video that the exception was thrown on using this code yt = YouTube('https://www.youtube.com/watch?v=t5OPuC-HpaE') and I see that playableStatus = 'Ok'. So I wonder if the issue has something to do with how the playlist object works/ looping through the playlist object?

[meen6thi]

I should also note that when I have run my script again after seeing this error while iterating a Playlist or Channel object, that it has always successfully retrieved the title for the video where I previously saw the error.

This seems to happen randomly, and isn't a rate-limiting thing - I've added sleeps between fetches, and run the script multiple times. Each time it falls over on a different video.

[andyskipper]

I've done a bit more digging on this - the issue seems to be that YouTube is running random tests for the prevention of media plays on third-party applications. That means that, randomly, it'll reply with "The following content is not available on this app". My assumption is that this is because every instantiation of a pytube.YouTube object goes through the steps to enable streaming or downloading, even if what you need is only metadata and not the stream itself.

Is there a way to force the YouTube object to only retrieve metadata, without preparing the object for streaming/downloading?

[bahree]

Bumping this. I have tried at multiple times for downloading - using a script that has worked in the past; I see the same behavior where this is randomly not working depending on how YouTube renders it I am guess as @andyskipper calls out. Curious if anyone has any ideas or suggestions on a fix? Thanks.

I have tried retry mechanisms as referenced in #1473 but to no avail...

Furthermore after implementing retry with sleep, it's seems Youtube has throttled me longer term - now I cannot fetch any videos.

If anyone has any ideas, do let us know.

Also #1466 and #1473 should likely be merged.

I have the same problem. It takes about 100 - 150 tries (While True) to "find" the video.

#1575 works like a charm. Fixes the issue without performance hits.
