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.
Really great explanation. Thank you.
