Cannot play 8k youtube video
Firefox fails to play 8k video from youtube: 1. https://www.youtube.com/watch?v=VaHSocnkSy4 2. Select '8k' quality from the gear popup or fullscreen on a large monitor with a fast network connection. 3. Youtube shows 'tv noise' and "An error occurred. Please try again later." Console says: Media resource mediasource:https://www.youtube.com/3387eab3-2666-4b79-8adc-09b928d9cddb could not be decoded.
Possibly we just need to bump the allowed video frame size.
Yep.

At least they give me Opus audio. :)
This may find some bugs in our software fallback paths, but there's only one way to find out.

Comment on attachment 8683875 [details] [diff] [review] Bump maximum video size to accept 8k. Review of attachment 8683875 [details] [diff] [review]: ----------------------------------------------------------------- Do we even need a limit anyway? IMHO this should be set by the various PDMs instead as it depends on the platform

(In reply to Jean-Yves Avenard [:jya] from comment #4) > Do we even need a limit anyway? Limits are any easy way to reject malicious files trying to OOM firefox with gigapixel video zip-bombs. > IMHO this should be set by the various PDMs instead as it depends on the > platform Ideally we support the same profiles everywhere. Where a particular platform isn't capable of some resolution we should fall back to software or fail independently of this check, no?
