Media Player Classic Home Cinema (MPC-HC) - DXVA!

[tetsuo55]

Hello Everyone.

We have a Release Candidate ready for testing.

VS2008 builds:
http://xhmikosr.1f0.de/index.php?fol...hjX21zdmMyMDA4

VS2010 buils(SSE2 cpu required):
http://xhmikosr.1f0.de/index.php?fol...hjX21zdmMyMDEw

Please test for codec regressions specifically(so files that worked before).
Please only report regressions compared to recent nightly builds.

GPU-Z showed 90-92% video decoder usage.

I guess one would need either VP3 or VP4 to decode them smoothly.

I tried a VP3 and it didn't work, so on to VP4.

not related: I tried the monkey clip with a 4500MHD.

Using the Microsoft DTV-DVD Decoder(DXVA), I can't recall exactly what happened, but either it didn't play properly or it was lagging.

Using the MPC Decoder (DXVA), it can play at ~60fps, but the 4500MHD + MPC Decoder has a bug where it produces artifacts on certain videos. I think it's skipping deblocking which would mean that it's skipping a step and load would probably be less when decoding.

Note that you used the word "decoder". I did not "stick it in". Please do not blame me for your inability to distinguish between a player and a decoder. I tried to correct the record for others viewing the thread, just as Superb did.

Congrats!

Are you sure it wasn't a custom renderer issue? Did you try w/ WMP12? When looking in GPU-Z (while playing), does the video decoder engine gets maxed out?
I thought VP3 would be able to play it as well.

You can go to the decoder's options and change the "skip deblocking" to "Never". That way you would know if that what allows the video to play at 60fps...

I have not. I might try it tomorrow if I can get my hands on the laptop with VP3 again. (Mine is the 9600M GT(VP2)/4500MHD - annoying hybrid graphics) With the VP2 card, it looks like the video goes fast and slow. However in splash player (also no stats) it looks fine and the system doesn't even sweat.

The Intel GPU doesn't report load. The VP3 card I didn't check, but I guess I will tomorrow.

I think that option only applies to software decoding.

Also, curiously enough, Splash player seems to be able to play the monkey file(ken_ross_02-1920x1080_60fpsRef4.mts) very smoothly with the VP2 card, but Splash player doesn't have stats.

[Superb]

Alright. Waiting to hear more VP3 testing results.

[v0lt]

We have a Release Candidate ready for testing.

Help me and I will add full support for PCM-sound for 'in24', 'in32', 'fl32', 'fl64' in mov-files.

Splash Pro v1.1 had - let's say a bug - and although is starting at 60fps, after a few frames goes down below 30fps
Splash Pro v1.2 is faster with AVCHD clips. It uses - I think - some kind of buffering and is moving between 40 fps to 60 fps, in loops.

You can benchmark Splash, using FRAPS.

Splash Player lite + 4500MHD is ~39-45fps.

MPC-HC (MPC Decoder - DXVA) + 4500MHD is ~59-60fps.

Download Splash Pro v1.2 trial.

For MPC-HC use internal stats.

That is what I have done. I will post VP3 results later, but that should be it. As far as I can tell, MPC-HC's DXVA doesn't seem to have a performance issue.

edit: the PC with VP3 which I have access to has Windows Vista, so I don't think there is any point in testing it's WMP.

[Superb]

~40-45 is about what I got w/ VP2 & Microsoft DTV-DVD Video Decoder (DXVA). It feels a bit smooth, but obviously not.

aleksoid might be able to help you.

If you come on IRC maybe someone else can help.
We would also like to ask you, do you want to come on the mpc-hc team?

Been using MPC-HC as a media player a long time now, but now decided to try and use it to view DTV.
My conf is Win 7 Ultimate 32bit, Terratec Cinergy T XXS USB DVB-T card and v2491 mpchc (using EVR for the testing).
Haven't used any previous ver of mpchc for dtv playback, so I'm not quite familiar with it.

Anyway, after some fiddling around, I still haven't quite got it to play dtv. As a remark, MCE7 and other DVB BDA players (DVBDream 1.5 for instance) play dtv very well.


Under Options, I have selected the following:
http://img715.imageshack.us/img715/9655/optionsm.jpg

Under Network providers, there are also options like: Microsoft ATSC NP (=Network provider ), Microsoft DVBC np, Microsoft DVBS NP and Microsoft NP. I have also tried the last one (MS NP). Under Tuner and Receiver there are no other options.

Now, the scanning doesn't receive any channels using the default range of 474000-858000 (BW:8000), even though during the scan the F-meter (F stands for what? ) seems to pick up signal, although the Q-meter doesn't show anything and no channels are found. If I set the range to 666000-666000 (that's MUX1 here, CH45), it doesn't also find any channels, if i set the range to smth like 642000-666000 (ch42-ch45), it finds programs on CH45 (on 2nd or 3rd attempt), but doesn't stop there, it still scans up to 858000 or smth.

Now, the programs/channels found, the viewing part.
This picture should be worth more than a 1000 words:

Should there be so many filters loaded?

[djsolidsnake86]

anyone can talk to developers about the proces that remain in background after exit mpc?
i have e8400, hd4850 and madvr 0.30

I see that behavior too. In fact there are two different problems :
1) The values set for the frequency range and the bandwidth are currently not taken into account. It not a big problem : this one line patch should correct the problem.
2) Sometime all the channels of a multiplex are missed by the scan, I don't know why because it works when I try to do step by step debugging.

Is akapuma required to post his request for supporting long description tags in the bug tracker to get any reply?

[XhmikosR]

Whatever everyone reports here will get lost after a few hours since this thread has become so big. So, always use the trac to report bugs or make new feature requests.

[renq]

How about support for LCN?
