Anyone is concerned by jitter problems ?

I made a lot of config for very differents computers, and the result is always the same.
Maybe different on Seven, but it adds other bugs.

Confirmed - on both fixes!
Thank you very much indeed.

On my laptop, it has an Intel X3100 graphics adaptor. It doesn't support DXVA acceleration of AVC, but I just wanted to try the mpc-hc.ini I have on my main laptop.

Setup:
Windows 7 64-bit
MPC-HC 1775 32-bit
EVR-Custom Presenter
Auto-load subtitles
Microsoft DTV-DVD Video decoder

http://img405.imageshack.us/img405/3394/84845244.jpg

What is of note is that the DXVA line says: "MPEG-2 variable-length decoder" with "Playing [DXVA]" also displaying.
I assure you the file is AVC/H.264 and it is also in the screenshot.

What is happening here?

Keiyakusha · 3rd May 2010, 02:21

Microsoft DTV-DVD Video decoder supports partial acceleration so "Playing [DXVA]" is probably right. It is possible that your graphics adapter can do that.
As for "MPEG-2 variable-length decoder" - have no idea. Maybe some bug... Someone else probably can comment on that.

namaiki · 3rd May 2010, 02:36

Curiously, it might actually be hardware(?) de-interlacing or something. I tried with and without vsfilter and with dxva enabled (vsfilter disabled) there was no combing of the video.

I guess since updating to a newer graphics driver DXVA playback produces artifacts. Using the non-DXVA internal filters the video is fine. It looks like this:

System OS is Windows 7 x64, MPC-HC build 1.3.1249.0, graphics card is an AMD Radeon 4870, graphics driver version is 10.4. Output settings is EVR+custom.

PS: Just checked and used ffdshow for decoding with hardware acceleration enabled. Same artifacts. So it's a driver issue. Probably not MPC-HC's fault.

PS2: reverted back to driver version 10.3. artifacts gone.

Aaah. btw, right now seeking with ffdshow+hw shows the same artifacts for a split second. so the bug in 10.4 seems to be that the driver is ignoring I-frames or so constantly...

Driver issue or not but checking in ffdshow can't tell you much since it uses the same code as MPC-HC

Snowknight26 · 4th May 2010, 01:41

No point in submitting bugs for r1249. Try updating MPC-HC first..

This is issue with 10.4 driver. You can download last version MPC-HC and set Disable DXVA for SD in video decoder Properties.

People work on parts that they are interested in.

Yes. I see.
So I don't grumble about MPC-HC.
I just hope MPC-HC will make better.
Gabest's MPC is a mythology.

It seems that you see something that others do not.

Perhaps you could try some experiementation on code yourself.

The internal x264 decoder must be buggy or something, cause I get lots of broken "squares" on the screen (not all time time, but every few seconds. Sorry I cannot find better words to describe it

When I unchecked H264 DXVA in options and let FFDShow handle it, it was all good.

namaiki · 4th May 2010, 08:56

Octo-puss" What is your GPU, what version of windows and what graphics drivers?

Create a new ticket and provide a sample and your system's specifications.

Right.

ATI 5850, Catalyst 10.4, Windows7 64bit, MPC-HC build 1824.

namaiki · 4th May 2010, 11:43

Octo-puss, just curious but what happens if you use the Microsoft DTV-DVD Video Decoding filter instead of the MPC Video Decoder (set as prefer in external filters)

Oh hell! Did you even read the last posts?

It's the graphics card driver, revert to 10.3. DXVA is broken in the driver, no matter what decoder you use. You obviously have hardware acceleration disabled in ffdshow.
