EVRCapture

babgvant — Mon, 14 Nov 2011 14:07:00 GMT

EVRCapture is a POC application that demonstrates the following DirectShow concepts for working with capture devices:

Use the PSI Parser filter to configure the MPEG-2 Demultiplexer both initially and as the media type changes
Split output stream with for display and file capture
Build a capture graph configuring crossbars and capture/encoder filters (Hauppauge Colossus and HD PVR are demonstrated).
Get screen captures from the EVR

DXVA is working!

Good new for those who jumped on Sage 6.5.1 for the EVR. They've got hardware acceleration working!

Don't know when 6.5.2 is coming, but hopefully not too long from now. Until then, here's a screen cap :)

MPEG2-TS[H.264 16:9 1080p@24fps, AC3/640Kbps@48kHz 5.1]

UPDATE:

No waiting involved, the fix can be downloaded from this thread.

SageTV 6.5.1 Beta with EVR support is available

Not much more to say.

Get it here.

UPDATE:

While the EVR is exposed, it doesn't actually work (VMR does). There are lots of other reasons to give it a go, I am...

Not quite what I was hoping for, but definitely a big step in the right direction.

UPDATE 2:

openning an elevated cmd prompt and running regsvr32.exe STVEVRPrstr.dll from the sagetv folder (c:\programfiles\sagetv\sagetv) fixes the EVR issue.

SageTV getting EVR support

Good news for Vista* SageTV users, I got an email last week** letting me know that Sage should be starting a beta with EVR support (6.5.x?) this week.

I can't wait to get the visual quality, and CPU offload that the EVR brings in an easy to use 10' interface (EVRPlay works, but its 10' interface didn't do so well my last SAF poll). If only I could get my HD PVR working, I'd be in HD heaven.

* It seems that XP users can also get the EVR by installing .NET 3.5; I haven't tested it, but a recent change to EVRPlay seems to indicate that it works.

** Reflexively, I assumed that it was something that carried an implicit NDA; occurred to me today that it might not be the case, so I asked. Real transparency takes some getting used to :)
