Another issue: The black screen
This happens (for me) when:
1. i start watching tv
2. i stop watching tv.
3. i start watching tv again
Now.. screen is black, but audio can be heard

See log2.rar for details

Note:
At 17:56:18 i stopped tv (step 2)
At 17:56:49 i started tv again (step 3)

vmr9.log shows some errors:
19-07-2007 17:56:50 [d98]ERR: Could not get IMFClock interface

i finally found the bug. it was a stupid mistake: dividing by the count of drawn frames in some IQualProp function. this would lead to divisions by zero when this method was called before a frame was drawn.

i will post updated sources (then already using multimedia timers instead of sleep for smoother playback) later tonight.

 

[Frodo]

great!

frodo: if you want to test it, just remove the Log() line in get_Jitter(...) near the end of EVRCustomPresenter.cpp.

edit: another thing i just noted: VMR9 deinterlacing is accidently commented out in VMR9.cs:563 (my fault). could you please uncomment it, and surround the call to SetDeinterlaceMode in VideoPlayerVMR9.cs:224 with "if ( !GUIGraphicsContext.IsEvr )". Thanks, Eabin

What sort of video hardware is required for EVR? I already run Vista 32bit, and I have an XFX 7900GT. I was told by someone in the IRC channel that I would need an 8500 or better, but I don't see why, I use EVR in KMPlayer in Vista, and it works just fine.

Indeed, EVR will work but without a DX10 video card you will not get any hardware accelleration.

OK, I get it now. It was you Comm, btw, who told me this in IRC.
(I'm _Spekkio_ there)

However, I installed PowerDVD 7, and ever since, I've stopped using CoreAVC because PowerDVD7's performance was superior. Are you sure my card cant take advantage of PureVideo. I know I don't have the superior VP2 these newer midrange cards have, but I have the VP1 (same as the 8800GTX), so shouldn't I get some performance benefit, even if it's not as good as what a VP2 card would?

 

[Eabin]

VP1 will accelerate H264 videos too, just not the full pipeline, but you will see improvements over software rendering. under vista you will need EVR to get the benefit - under XP it works with VMR9 and DXVA1 too.
