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

Perhaps EVR-Custom hasn't taken into account a situation where the monitor is set to less Hz than the video being played.

[Keiyakusha]

what are the differences between his and alexins versions?
Maybe version of some compilers can be a bit different but the most noticeable difference is the name of the person who compiled it.

[XhmikosR]

It also takes like half a second to pause and resume the video with r2153 using the mouse. I've already informed Alekdoid1978.

Can someone with a 24P display look into this?

[Aleksoid1978]

There's a bug with 2153, in MKVs with chapters(not ordered/linked chapters), when you press Page Down to jump to the next chapter or right-click, Navigate, Jump To, Select a particular chapter to jump to, after a few seconds of playback it pauses. Bug does not happen with 2152, so the problem started with 2153. Please revert 2153.

Upload short sample for test.
Changes in 1253 do not relate to work with MKV and chapters.

I've studied the source code of the custom EVR renderer a bit, and it tries to set the output format of the EVR mixer to anything but RGB. Despite this, it always renders into RGB textures, so obviously the output can only be RGB. It doesn't make any sense, and I think this behavior is erroneous. According to an MSDN article (http://msdn.microsoft.com/en-us/library/bb530107(VS.85).aspx#allocatingdirect3dsurfaces), the output format you set and the one you actually use must match.

By the way, I believe this also explains why the 10-bit video path is so buggy. Yes, the GPU drivers have faults (the mixer should return an error code instead of crashing the entire application), but MPC tries to do something which is not really supported. For example, my NVIDIA NVS 5100m reports that 10-bit RGB mixer output is not supported, but it seems to be working anyway (only with progressive content). MPC should definitely check whether 10-bit output is truly supported before using it. However, I doubt that there are any such GPUs at the moment. The bottom line is, this feature in MPC is pretty much broken. The only valid solution I see is to use a non-EVR/VMR renderer that natively supports a full 10-bit video rendering path.

It seems that the drivers are too tolerant (lazy), but MPC should not rely on this. If the MPC developers agree, I will gladly help to fix this.

I thought it was OK to just go ahead and make your own build? Just do it and offer it up to test I say (But then I don't know the rules on open source stuff so ignore me if I am being flippant about it) :)

I beg your pardon.

In the link http://www.xvidvideo.ru/media-player-classic-home-cinema-x86-x64/
versions are still svn 2099, where you can download the most recent ones?

THANKS

@stasi

You can get XhmikosR builds here (http://xhmikosr.1f0.de/).

That link is just one page back...

[ryrynz]

Do people know how to use search and actually read anything from the thread at all?

[XhmikosR]

And a few pages back I explain that the crash on exit happens with all the builds, it's just that with MSVC2010 it happens more often for some people that it did with MSVC2008. So if someone is a programmer and can help fix this, please do so. :)

[hajj_3]

is Hardware decoding enabled in the latest MPC-HC V2099 with an ATI card using ATI 10.7 drivers that were released yesterday or is vlc 1.1.1 the only free player with hardware decoding for ATI cards?

[namaiki]

I believe MPC-HC has worked since Catalyst 10.4 for most videos.

[cengizhan]

Regarding the pause issue. For me there was always something wrong with the pause and resume. Open a big mkv file from a slow medium like dvd/flash disk. press pause, then play, then pause, then play. Program says paused but video plays. After that you have to restart the program to fix the issue.

You are right, pause and seek have always been problematic, maybe this new level of problem can help the developers locate the exact cause.is Hardware decoding enabled in the latest MPC-HC V2099 with an ATI card using ATI 10.7 drivers that were released yesterday or is vlc 1.1.1 the only free player with hardware decoding for ATI cards?DXVA has worked for years, but im not sure if 10.7 fixes the standard def corruption bug

[Snowknight26]

Nope, still broken.

On an unrelated, and apparently fruitless note, preferred filters aren't always loaded even when a connection can be made. For example:

File A contains two tracks, a FLAC track (track A) that's decoded by the chain source splitter -> madFlac -> ffdshow audio decoder and B, decoded by source splitter -> ffdshow. ffdshow audio decoder is set to preferred and accepts both uncompressed audio (for track A) and the original format of track B. Pressing A in MPC-HC, which goes to the next audio track by default), switches from track A to track B. Track B is still being decoded by ffdshow, so so far so good. However, if you press A again, track A is played but this time instead of being handled by the normal chain, ffdshow is no longer present and madFlac connects straight to the audio renderer.

This behavior is especially problematic when ffdshow is set to downmix or upmix uncompressed audio as MPC-HC can't do it on its own. But oh well, apparently bugs in this thread aren't even looked at so I'm just wasting my time typing this. :)

[crewxp]

random quick question. is there any way to set mpc-hc to run in the background of the monitor, forced fullscreen? I know VLC has something like this, but it disables windows aero.

aka: So I can run a video as a 'wallpaper'

this would be a neat feature since dreamscape was discontinued.

[oddball]

ffdshow for processing refuses to load with CoreAVC in MPC HC. Using Windows Media Player I can get CoreAVC to load and use ffdshow's processing. But I want to use MPC HC.

Any ideas?

[namaiki]

Try add both as preferred in External Filters list.

[oddball]

OK I seem to have broken MPC's internal decoder fiddling with filters. Even though the internal decoders are ticked I get an error on playback. I tried reinstalling MPC and doing a system restore but it's still busted. "Media Player could not render some of the pins in the graph" etc. I tried to register MPCVideoDec.ax again but no joy.

Any ideas?

BTW your suggestion worked.

[THX-UltraII]

Am I correct that BR (BDMV/CERTIFICATE folder) still is not supported fully by MPC-HC?

I tried to open a directory and select the BDMV folder. Sometimes this seems to work and the movie starts playing but sometimes it doesn t work and the movie begins to play with the directors comment.


ps. I ve checked ONLY MPEG PS/TS in the internal filters of mpc-hc

You can load the MPLS for the main movie and that'll work just fine. I use eac3to to give me the most likely candidates. If you do an open DVD on the BD, MPC-HC will make a best guess, but, as you've seen it doesn't always get it right.

[nevcairiel]

Running the "index.bdmv" usually works just fine.

Whats the MPLS? and what do you mean by using eac3to?

EDIT: do you mean to first convert my movie to a .m2ts file with http://forum.slysoft.com/showthread.php?t=25818
I know this is possible but it takes ages to convert. I was just hoping that MPC-HC can handle a BD structure folder.

[SamuriHL]

Whats the MPLS? and what do you mean by using eac3to?

The MPLS is the playlist for different parts of the disc. The main movie will have one. You can scan the BD structure with eac3to and it will list the most probable candidates for the main movie MPLS file.

Ok, so MPC-HC does not support it fully at this moment. I think I ll convert them to .m2ts for the time-beeing then.

Wait, huh? That's not what I said at all! :) It usually does just fine on BD structures. But there are some discs that have screwy layouts that have different MPLS for the movie that add "special features" mixed into the main movie. Sometimes MPC-HC gets a bit confused and picks the wrong playlist by default. It's simple enough to open an MPLS. They're in your BD structure. It's MUCH quicker to find the MPLS of titles that don't automatically get picked up correctly than to convert it to m2ts.

is an MPLS a folder or a file?

[SamuriHL]

is an MPLS a folder or a file?

Look in your BDMV\PLAYLIST folder. It's a file. There's going to be tons of them in there, but, you can usually identify it with bdinfo or eac3to just running it on your bd folder.

[dbone1026]

If you only plan on using MPC HC for BluRay playback you might as well just use Clown_BD to grab the main movie, that way you don't have to worry about multiple playlists or grabbing the wrong movie.

That's a fair enough assessment.

[zegames]

Add files to Windows Media Player list, go to menu File > Save Playing List as.. and save all possible formats: Playlist1.asx, Playlist1.m3u, Playlist1.wpl

Now, try to open each one in MPC, only m3u format will work. Can someone confirm this 'bug'? or this is a normal behavior? I'm asking it, because in MPC options > Formats you can associate with several playlist formats, including all cited by me.

Other thing, saving playlist from MPC will result in a format similar to m3u (.mpcpl), except for the full path for files. Playlist generated by Windows Media Player will result in relative path, what is fantastic for use in any computer, good to send all files to flash drive. Good suggestion? Can be implemented?

[tetsuo55]

Can anyone confirm that on ATI, With Catalyst 10.7, SD resolution h264 DXVA does not work on MPC-HC but DOES work on VLC?

[sneaker_ger]

Can anyone confirm that on ATI, With Catalyst 10.7, SD resolution h264 DXVA does not work on MPC-HC but DOES work on VLC?

HD 5850, Win 7 x64, CAT 10.7
SD: artifacts in both players
HD: works fine in both players

[oddball]

OK all fixed again. Is there any way to use ffdshow processing on DXVA?

[SamuriHL]

I use ffdshow dxva on everything. Just add it in external filters and set it to preferred and uncheck the internal filters.

[Keiyakusha]

He probably wants to use ffdshow's postprocessing. No, not possible.

[oddball]

OK just checking. Works with CUDA and CoreAVC though so no biggie :)

[JarrettH]

I don't know how good an idea this is, I was trying to get dxva+dvds+evr+subtitles working last night to no avail, but I just ended up searching for some subtitles online instead. It would be neat if MPC could automate this somehow.

[burfadel]

Ok, here's an interesting question...

Most CPU's should be capable of handling HD h264 decoding correct? For DXVA decoding, obviously the CPU use will be very low as the decoding is done on the graphics card. What is the difference in the amount of electrical power consumed by the computer between DXVA deconding and CPU decoding.

Of course, I realise that this varies greatly with different system configurations, I'm just referring to a generalised scenario.

[Keiyakusha]

So, where is the question? About most CPUs? Everything with single core, old dual cores, some notebooks etc. can't play HD fine. Don't know if this is "most" or no.
Of course decoder should be taken into account. Some software decoders can be twice slower than others.

Power consumption may be lower if we talking about passively cooled low-end gpus. Otherwise it can be higher. Also CPUs always using some amount of power even if they do nothing. It may be twice lower than when they do some computing but you still should take this to account.

So, if CPU has no problems with decoding, most people don't need dxva.

[crewxp]

Just thought about this...(regarding my previous question)

If the feature is not built in mpc-hc, is there any way to launch a mpc-hc using command line options? (Launch it in fullscreen, on the back-most layer of the monitor, not always on top, and disable the toolbars (so the mouse doesnt activate them when it rolls over the mpc-hc)

[Kado]

@crewxp

Open MPC-HC

Don't know about "wallpaper mode" though.

[aerodown]

Hi,

Everytime my computer go to sleep mode and after wake up i open mpc-hc and go to mpc-hc toolbar and select File to open video mpc-hc will not responding. I try to kill the mpc-hc.exe process through task manager but cant and i cant even shutdown the windows it just stuck at Windows is shutting down.. so i have to force shutdown or force reboot the pc. Happen on mpc-hc 1.3.2099.0 that i download form xvidvideo.ru and i compile the latest 1.3.2163.0 still same. I think happen after i update windows, and the last windows update that i perform was kb2032276. before this i never have this problem. Anyone have this same problem ?

mpc-hc x86 1.3.2163.0
Windows 7 Ultimate x64 (fully update)
Nvidia Driver 258.96

[XhmikosR]

@aerodown: Try using another renderer like EVR.

[SoLoR]

OK here is my issue.

My ISP have IPTV over multicast. Im using udpxy (multicast to unicast coverter) to stream IPTV on my LAN. Udpxy just gives access to udp multicast streams over http protocol. Those streams are MPEG TS streams, using MPEG1/2 for SD channels and MPEG4/h264 for HD channels, audio is encoded in mp3 format (sometimes multichannel for different languages), there might also be teletext and multiple subtitles. I have m3u playlist made for this, but everytime i try to load it mpc-hc "stops responding". Also if i try to open single stream its same result. I assume MPC-HC currently just does not support that, so my question is if it ever will? At least basic playing functions (if not choosing different audio tracks and teletext) because currently im kinda forces to use VLC for IPTV and mpc-hc for everything else and in all honesty i dont like picture quality of VLC...

[nevcairiel]

MPC-HC isnt particularly happy with streamed mpeg streams. You could try using another MPEG Splitter and see if that helps.
