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

[mikelebron]

Latest build broke m4a (Apple Lossless)... I new I was not going crazy!

I have all internal filters enabled in MPC-HC Build 1420 using default renderer.

It states there is no supported codec..


question... Does MPC-HC play m4a (apple lossless) format? I thought it did..

It only supports ALAC in M4A when you have QuickTime (or QT Lite) installed. It also only only works with 32-bit MPC-HC.

[fastplayer]

In the status bar text like "Playing" or "Paused" keeps flickering/refreshing from time to time. Why?

[mikelebron]

Hmmm... I will check to see if my QT was uninstalled... but I know it was working in a prior build (32 bit)

Very odd it would stop working with the newer build...

Anyway for me to verify if the codec is installed properly? Are there any splitters required for them to play properly (ie Haali, etc.)?

[flanger216]

MPCAudioRenderer works for me but it has some limitation as of now: Volumn Control does not work and it does not support rendering 32bit float PCM data. As far as I know Vista/7 audio rendering stack works with 32bit float audio data so if MPCAudioRenderer supports this data format, an unnecessary conversation won't occur.

For now the renderer only uses a WASAPI exclusive connection, so volume control isn't supposed to work... by design. Also, a 32bit float connection in a bitmatched environment (again, since this is a WASAPI exclusive connection) is neither feasible nor necessary: there aren't any unnecessary conversions, because the Windows mixer is taken out of the loop entirely.

[thuan]

ic, didn't know it use WASAPI, but personally I prefer to be able to change my volume from the player and I don't need perfect bitmatched, as long as it's inconceivable lost. I will keep on using normal DS then for now.

[Keiyakusha]

If I'll put ffdshow raw video filter (which will resize SD to HD) in between of decoder and renderer, it seems another colorimetry coefficients will be used. I can correct this with haali renderer, but how can I control this in EVR-CP? Or maybe I should control this from ffdshow? In my case both input and output in raw video filter is YV12.

[clsid]

The renderer assumes it needs to use BT.709 colors when the input video has HD resolution. But since you are resizing SD video, your input is BT.601.

You can use the BT.601 -> BT.709 shader to correct the colors.

[Keiyakusha]

Sorry I probably bad in explaining. This shader does the opposite thing. As I understand BT.601 is for SD. When its upscaled renderer thinks BT.709 should be applied. I want to make it BT.601 again or better just prevent any conversion.

EDIT:
For example:
This is SD without upscaling (http://imgur.com/yU0Mk.jpg)
This is with upscaling (http://imgur.com/q2FGO.jpg)
And this is with upscaling + shader (http://imgur.com/McQLz.jpg)

[clsid]

Then someone needs to add a new shader that does the inverse conversion.

[Snowknight26]

MPCVideoDecFilter.cpp:998 should be changed to say "too many reference frames", not "too much ref frame."


While we're at it, line 998:
if (m_nCompatibilityMode & 1) MessageBox (NULL, _T("DXVA : too much ref frame"), MPCVD_CAPTION, MB_OK);
should be changed to
if (m_nCompatibilityMode & 1) MessageBox (NULL, _T("DXVA : too many reference frames"), MPCVD_CAPTION, MB_OK | MB_SETFOREGROUND);


Line 993:
if (m_nCompatibilityMode & 1) MessageBox (NULL, _T("DXVA : SAR is not supported"), MPCVD_CAPTION, MB_OK);
to
if (m_nCompatibilityMode & 1) MessageBox (NULL, _T("DXVA : SAR is not supported"), MPCVD_CAPTION, MB_OK | MB_SETFOREGROUND);


Untested though..

Ever since I decided to futz around with Windows 7, I cannot get DXVA working properly in MPC-HC. When playing back videos with subtitles, I get frame drops and the audio either crackles/stutters/skips. This happens with compliant and non-compliant DXVA encoded videos.

Setup:
Core 2 Solo 1.4Ghz
Intel X4500mhd
Windows 7 32-bit
Latest Intel and Realtek Drivers.

The audio problem occurs either using MPC-HC internal decoder or Microsoft's DTV-DVD Decoder. I've tried various version of MPC-HC to no avail.

This is something I noticed this morning...the audio problem goes away when I switch the renderer to EVR instead of EVR Custom Pres. With EVR, the video plays back perfectly fine. It looks to be something with rendering the subtitles thats causing the problem.

This is annoying me because this never happened under Vista. Has anyone else run into this problem with a setup similar to mine?

[xiaonan04]

nVidia series 8(9)xxx for H.264 only
ATI Radeon HD series for H.264 and VC-1 decoding
Windows XP users, select Overlay Mixer, VMR7, VMR9 or VMR9 renderless
Vista users, select EVR or EVR custom renderer
Windows XP users, select VMR9 renderless
Vista users, select EVR custom renderer
In "Options / Playback", tick the checkbox "Auto-load subtitles

[THX-UltraII]

I see that a new output is available in the MPC-HC settings called 'MPC Audio Renderer'. What does this exactly do? Is Reclock not needed/usable any more with this setting?

[Abradoks]

I can correct this with haali renderer, but how can I control this in EVR-CP? Or maybe I should control this from ffdshow?
You can convert to RGB with ffdshow, or use Colormatrix to correct coefficients. If you prefer shaders, here is simple "BT.709 -> BT.601":
sampler s0 : register(s0);

float4 main(float2 tex : TEXCOORD0) : COLOR
{
float4 c0 = tex2D(s0,tex);
return float4 (0.00792238*c0[2] + 0.0784776*c0[1] + 0.9136*c0[0], -0.0671271*c0[2] + 1.17217*c0[1] - 0.10504*c0[0], 0.9582*c0[2] + 0.0322218*c0[1] + 0.00957823*c0[0], 0);
}

I re-wrote "BT.601 -> BT.709" some time ago. Maybe someone will find it useful too. Comment describes were final coefficients come from. "BT.601 -> BT.709":
sampler s0 : register(s0);
float4 p0 : register(c0);

#define height (p0[1])
#define width (p0[0])

float4 main(float2 tex : TEXCOORD0) : COLOR
{
// original pixel
float4 c0 = tex2D(s0,tex);

// activate conversion only when VMR uses wrong colorspace (cropped or downscaled HD)
//if (height > 719) {return c0;}
//if (height < 600 && width < 1025) {return c0;}

// r=c0[0], g=c0[1], b=c0[2]

Tetsuo55 , I have one question:
In the bug tracker (http://sourceforge.net/apps/trac/mpc-hc/report/1) I notice that every week, the number of bugs listed by users increase but when I read the timelime (http://sourceforge.net/apps/trac/mpc-hc/timeline) I notice that each version correct some problems but these problems are not written in the bug tracker and those written in the bug tracker are not corrected. Even bugs in red colors (the most important) are not corrected even after many months.
My question is: Does bugs listed in the bug tracker will be soon corrected ?

Excuse me but It is just a question and not a complaint.

MPC-HC is a volunteer project, most volunteers only fix problems they are interested in.

Most of the problems on the tracker are very complicated and take a lot of time to fix, most devs do not have that amount of time available.

Currently we have devoted dev time to fixing crashes and outdated libraries, this will result in a bunch of bugfixes.

Try select disable subtitle animation under 'Subtitles' in MPC-HC options, and make sure 'sub pics to buffer' is 3.

[Keiyakusha]

I will try it later, thanks!

[xelox]

Try select disable subtitle animation under 'Subtitles' in MPC-HC options, and make sure 'sub pics to buffer' is 3.

I have tried that. But, that does not solve the problem at all.

It's really strange that it only happens with Win7 and not Vista...unless there is something that Win7 is doing that Vista didn't.

So far, the best combination was using Win7 default sound drivers, MPC-HC svn 1000 and MS DTV-DVD decoder. But, MPC-HC still showed frame drops and audio still popped, crackled, stuttered, etc. at points.

Thank you very much but I have another question:
Why, in the bug tracker, do you have an order of priority if developers don't fix these problems and don't use these priorities? What is the interest of these priorities (red, yellow, grey and blue)?

I thought that bugs referenced in red would be corrected in priority, and after bugs in yellow and after bugs in grey and after bugs in blue.

For example, ticket 16 exists since more than one year (numoranscer is the author for information). In the old bugtracker priority was 9 (the higher) and now priority is red (the higher) and no fix.

I understand that this project is a volunteer projet (and you make a wonderful job) but I ask myself the interest of a bugtracker if the problems referenced here are not corrected and why problems corrected by volunteers developers are not referenced in the bug tracker.

[swp]

I have a very strange problem - please help!

Config:
Windows 7 64 bit
MPC-HomeCinema.1.3.1249.0.(x86)
ATI 5850 - HDMI Audio - multichannel PCM - Onkyo 605 (used for movies - set in playback/output)
SB Xfi - headphone (used for everything else)


Now almost everything works fine - including 24p playback without tearing etc. - except one thing:
xvid (avi) movies with mp3 audio have a strange popping sound when playing with MPC HC. Same thing with zoom player and ffdshow.

The movie plays OK with winamp and WMP12 with the same audio config, i.e., the movie itself + ATI HDMI audio out + receiver should be OK,

If I play with MPC HC but set the audio output to the XFi then the same movie plays OK.

In all it seems to be some strange issue between MPC HC - ATI HDMI Audio - multichannel PCM

Two additional strange observations:
When playing with ATI HDMI Audio settings I set 24bit 192 kHz. Then there was no noise for a while then even worse after around 30 secs
I even tried to use AC3filter to encode the output from MPC HC and send encoded stream through ATI HDMI Audio to the receiver. In this case there was no noise, but the playback was "ragged" - sound - stop - sound - stop ....


I am really lost and would really appreciate some help...
Thanks!

If you heard about anything like this plz. let me know to at least have something to experiment with...

[DMD]

I apologize for the two questions, but I have not read the whole thread.

1 - I have a 32-bit Windows 7 must also install DirectX 9 or are included in DirectX 11?

2 - What are the best setting for playback for Blu ray disc

THANKS

[namaiki]

1 - I have a 32-bit Windows 7 must also install DirectX 9 or are included in DirectX 11?

You have to install it. It is not included.


question
We don't use the priority system for bug fixing order, but rather for old vs new bugs

[DMD]

You have to install it. It is not included.
Thanks will instantly

[tetsuo55]

Thank you very much but I have another question:
Why, in the bug tracker, do you have an order of priority if developers don't fix these problems and don't use these priorities? What is the interest of these priorities (red, yellow, grey and blue)?We do order the bugs for stuff that has to be fixed before the version number can be increased, but that only means the next version will take a long time to be released

I thought that bugs referenced in red would be corrected in priority, and after bugs in yellow and after bugs in grey and after bugs in blue.It does mean that in a way, it means the red ones have to be fixed before a new version, like 1.4 can be released.

For example, ticket 16 exists since more than one year (numoranscer is the author for information). In the old bugtracker priority was 9 (the higher) and now priority is red (the higher) and no fix.This bug appears to be very difficult to fix, devs have tried a couple of times already. We hope someone who is not on the project will provide a fix for us.

I understand that this project is a volunteer projet (and you make a wonderful job) but I ask myself the interest of a bugtracker if the problems referenced here are not corrected and why problems corrected by volunteers developers are not referenced in the bug tracker.The bug tracker is primarily used to keep a list of known bugs, and though providing as much data as possible, we hope that users will provide patches for these problems (this happens quite regularly, but usually not for difficult bugs like #16)

No crashes here with 1443 on XP. I have only tried some mpeg files, not DVDs.

[mark0077]

Not sure exactly what build recently introduced this but when I minimize mpc and restore it again I get an ugly audio blip. Reproducable every time. Will go back through older builds to see where it came in.

Using wasapi out from reclock and evr-cp with nvidia card. Anyone else seeing this.

[DMD]

Wonder if you can set before playing any files or Blu ray disc, the option to choose audio and subtitles.
Avoiding a time to manually set the selection when playback is started, going in the path Navigate> Audio Language or Navigate>Subtitle Language

Thanks

I just tried the latest version with Windows 7 support.
Is not possible to use the right click menu on the taskbar as a recent played files history (just like happens with the Windows Explorer icon)?
