This plugin uses GPU hardware accelerated video decoding on Windows via Direct3D 12 Video.
See: https://learn.microsoft.com/en-us/windows/win32/medfound/direct3d-12-video-overview
At present this plugin supports the following codecs, provided there is support by your GPU
(via vendor provided extensions) with some limitations:
H.264 / AVC
- Only Baseline, Main and High profiles are supported
- Constrained Baseline profile can be used (no FMO, ASO and RS)
- PAFF and MBAFF are not supported (interlaced video)
H.265 / HEVC
- Only Main and Main10 profiles up to level 6.3 are supported
NOTE on usage:
==============
By default, even with this plugin enabled, its use is disabled on Windows due to the
vast combinations of GPUs and driver implementations.
It can be enabled via CVar / .ini file
To enable via ini file add
[ConsoleVariables]
ElectraDecoders.bDoNotUseD3D12Video=false
to the respective platform's ini file.
To enable by default at compile time, override the method
protected virtual bool bIsDefaultIgnoredOnPlatform
{
get
{
return false;
}
}
from the base D3D12VideoDecodersElectra.Build.cs build script in the platform build
scripts where you want it enabled.
For testing you should confirm operation by setting the console variable
`ElectraDecoders.bDoNotUseD3D12Video`
to `false`.
To disable the plugin right at Startup() you can use the CVar / ini setting:
[ConsoleVariables]
ElectraDecoders.bDisableD3D12Video=true
This acts as a master switch. When disabled `bDoNotUseD3D12Video` has no effect.
