Well as i said i haven't been through all the code yet. ( a lot of code, little free time )
And that part is one that i haven't been through properly yet.

I didn't mean it to sound as a suggestion, it was more of an explanation to the non-programming users and the new programmers out there.

Hope that clears things up

will the problem with the "non clean termination" of MPC-HC ever be fixed i often have 1 ghost instance of it in my proccess list that also blocks most of the times ffdshow, i also read that many seem to have this instability problem (Winxp SP3 here) and this seems to exist for a long long time i allways ignored it killing this 1 instance manualy that didn't terminated itself properly, i wouldn't say it's a showstoper but it's quiet anoying anyways as you would expect it to terminate itself in a clean way closing all it's handles.

Is it known what causes the non clean termination? Subtitles maybe?

are you using winamp plugins?
I never have this problem but i only use mpc-hc and ffdshow and nothing else.

oh yes, please let us know what infos you need to fix this bug

would ProcessExplorer logs do? it's definitely related to ffdshow(possibly the Avisynth filter), apparently some threads are not killed properly when MPC closes up...so it stays as a system process(I also run XP SP3)

sometimes I had like 10 of them! maybe you could simply kill the process the hard way...or at least offer an option to do so in the options

Hello,

Is someone still working on the LPCM mono issue? Do you need samples?

In 1.2.908.0 playing the m2ts files from Criterion Blu-rays with LPCM mono causes slow playback and garbled audio. After 1137 the garbled audio is fixed but everything is still playing at 50% speed.

Here are two samples:

http://www.mediafire.com/?nedy2ydd1tu
http://www.mediafire.com/?jjmyemjedf2

rep.m2ts should have a 24-bit LPCM mono track, and wag.m2ts should have a 16-bit one. Both play at 12fps instead of 24fps in MPC-HC. If I disable the internal MPEG PS/TS/PVA source filter and use the Haali splitter instead, the files play at full speed, but no audio is recognised at all.

I'm afraid it's a very random problem...but it never happens w/ KMP. it happens both w/ audio and video files...and it seems related to ffdshow.

if you could just add an option to do a more agressive process killing when closing MPC, that would do I think

actually a friend of mine(Seb.26) made me a small helper, that will "process -k mplayerc.exe" when closed down...but well, it's still annoying coz it increases the loading time(which is so fast in MPC that I don't wanna ruin it )

maybe CrunCher will have better directions to offer.

like i said, this never happens on my system with plain mpc-hc and ffdshow.

Lets hope CruNcher can explain how to reproduce it.

I dimly remember having had a zombie MPC process at work time and again after using MediaPlayerConnectivity to open some random video files off the web in MPC... but that's about it; I only noticed Windows wanting to terminate it when logging of at the end of the day...

np: Death Cab For Cutie - Sweet And Tender Hooligan (Live) (Live At The Crocodile Cafe 25.02.1998)

It would be useful if the devs could add more debug prints to MPC at strategic places in the code. Now it mostly only prints info in the filter manager code.

Then we can make a public debug build for those who suffer from stability problems. Users can easily log the debug output with the DebugView tool:

I was just wondering if the DXVA is a supported feature with BD movie on mpchc because i tried on another pc (not mine) and it doesnt work.
I dont have BD drive on my own pc so i cannot check and post a feedback.

You have to use a tool like anydvd to decrypt the disk first.

Microsoft made a page on MSDN explaining the bitstreaming of all supported audio formats over HDMI, Displayport and Spdif(on a different page).

Every bitstreamable format is explained on that this page except for 1, DTS-HD.

http://msdn.microsoft.com/en-us/libr...61(VS.85).aspx

Anyone interested in enabling bitstreaming for all these formats in MPC-HC?

I gonna try to reproduce exactly why it happens but im pretty sure it has todo with the combination of multiple MPC-HC loaded and useing them in the same time with ffdshow, closing and reopening videos via drag & drop and somehow when you close all the open MPC Windows then it often happens that 1 instance stays without a window open (whyever that is).

That would explain why I never experienced it because I use single instance mode.

so did I, it's just that if you open many files in a row....this will happen.

it's so damn annoying, because when it happens w/ video files then it makes the system sluggish and laggy.
