Screen Saver Freezes on certain videos (404)

[amirHizkiya]

Hi,

After running the screen saver for a while I would come back to my TV either being stuck on a black screen or a frozen picture.

Took me a while to investigate, but searching through Logcat it seems as though the app is hitting a 404 on some videos and just bugs out.

Maybe we can we remove those videos from the playlist, but more importantly maybe we can gracefully handle a 404 to just skip to the next video.

Note: I'm still trying to track down the videos, it seems to be coming from either the
2018 4K or 2019 4K playlist. I'll update if I get anymore information. I think one is Los Angeles and one is Hong Kong.

Edit: Note sure where its coming from.

Maybe this will help.

Thanks for the report, but this project is in maintenance mode.

If you'd like to submit a fixed playlist I'd be glad to approve though.

[amirHizkiya]

Gotcha. I think the playlists are downloaded direct from Apple so I don't think I have access to them.

[cachapa]

Exactly, so if there are 404 errors, then that either means the playlist is wrong (we might be fetching an old version) or something else is going on.

[amirHizkiya]

Oh. I thought that maybe it was a 404 on the video itself because its not all videos.

[cachapa]

That's what I meant. If some videos are no longer loading, we may be fetching from an old playlist which is pointing to videos that are no longer there.

I doubt Apple is using a playlist where some videos are throwing 404s, so the most likely explanation is that there is a new playlist somewhere which doesn't have that problem.

The issue is that Apple also tends to change their playlist format over time, so it's not guaranteed that the fix will be as simple as updating the playlist URL.
Worth a try though.

Hey I use this app all the time on my chromecast and its great, so thanks for making it. I also have these 404 issues and found a couple links that might have more updated versions of the playlists if you are still interested. Hope this is helpful.
