1853448 - Support HEVC via Windows MFT
bugzilla.mozilla.org
RESOLVED (alwu) in Core - Audio/Video: Playback. Last updated 2023-09-30.

We will support HEVC playback via Media Foundation transform (MFT).

HEVC playback will be supported via the Media Foundation Transform (MFT) and WMF decoder module will check if there is any avaliable MFT which can be used for HEVC then reports the support information.

HEVC playback can only be support on (1) users have purchased paid HEVC extension on their computer (SW decoding) (2) HEVC hardware decoding is available on users’ computer

For now, I’d like to only enable HEVC for the media engine playback, but keep the HEVC default off on the MFT. Because the media engine is an experimental feature, which is off by default, it’s fine to enable HEVC for that.

HEVC playback needs hardware decoding, and it currently only support on Windows. HEVC playback check would be run when the task is in the mda-gpu, which has the ability for hardware decoding. On other platforms, HEVC should not be supported.

    So fuck users that do don’t use Windows right? Firefox contributing to the fragmentation of the web and pushing users to surveillance software is the exact opposite of what it should be doing.
