![]() ![]() in terms of need to integrate with Media Foundation pipeline (if necessary), however the performance gain is not so likely: stock Media Foundation decoders with hardware decoding enabled add reasonably small overhead. It might offer better flexibility, presumably the complexity is higher esp. It is possible to use IHV SDK to talk to decoders otherwise. Translate santacIous AUTHOR New Here, So which is used in version 14.5 when exporting as in this video. The bottom line is that stock decoders is the suggested method to consume hardware backed decoding. NVENC remains the default with supported Nvidia GPUs, but somewhere in the Preference settings you must manually make the selection on first launch whether to use Nvenc (default) or QuickSync. For the formats not covered by DXVA2 and/or stock decoders IHVs do ship dedicated decoders in form factor of asynchronous hardware MFTs (M-JPEG, VP8 formats, for example). ![]() Dedicated true hardware MFT decoders would not offer any real advantage. IHVs do not ship separate hardware MFTs for H.264 and H.265 because the mentioned stock decoder MFTs are already integrating hardware decoding capabilities in efficient way. H.264 Video Decoder MFT and more recent H.265/HEVC Video Decoder MFT have a different structure: they combine software decoder as a fallback code path, utilize hardware decoder via internal use of DXVA2 API and are synchronous decoders. Encoder Comparison NVENC x264 Quicksync QSV VP9 and AV1 on twitch. Indeed, hardware MFTs have a documented requirement to be asynchronous. Nvenc Discord Ability to use NVENC (Nvidia GPU) instead of CPU while sharing screen. Elaborating follow up questions in the comments below, there is nothing wrong in H.264 Video Decoder MFT being a synchronous MFT. If you are looking for hardware-assisted decoder, the Media Foundation API offers that via H.264 Video Decoder, which is capable of taking advantage of DXVA2 API, which in turn uses hardware capabilities to decode H.264 video. Intel Quick Sync Video H.264 Encoder MFT is also an encoder object. Microsoft H.264 Video Encoder is for encoding. ![]()
