MediaStream class for playing compressed audio about directxtk

[AlvisDEV]

This is what we really need. When will this great feature be published? Is there any plan to make a video renderer?

What is it exactly you are wanting to achieve here?

The XAudio2MFStream and XAudio2AsyncStream samples on GitHub already implement basic streaming, but this work item is for having some kind of helper that does the XAudio2MFStream thing in a portable way across Xbox One, PC, and UWP. If you are just looking for a PC solution, see the sample.

Video is problematic because there's really no Microsoft solution that is portable across Xbox One, PC, and UWP: each has a slightly different solution especially if you want 'down-level' support for Windows 7. The vast majority of games just use something like Bink.

I do work on UWP and windows 7 desktop. So stream audio helper for both UWP and Desktop is needed.
For video, I don't need "down-level" support, basic video playback is fine. I am now focus on media foundation to check is there any solution for both windows 7 and UWP.

What do you mean by 'basic video playback' exactly? Full-screen cut-scene rendering or render-to-texture that you then put onto objects?

BTW, Windows 7 desktop is down-level support these days :)

Full-screen or windowed rendering

With XAudio 2.9 already supporting xWMA compression, and the XAudio2Redist providing xWMA support for Windows 7 and Windows 8.1, the work I did on SoundStreamInstance already addresses the majority of this work item.

Video was always a bit out of scope for DirectX Tool Kit, but there are some samples available for some of those scenarios:

• VideoTextureUWP
• VideoTextureUWP12
• VideoTexturePC12
