|
|
I've been using MPC Home Cinema for bluray playback, using ac3filter and Haali. The only bluray I've had is WallE, and it's worked quite well.
My only problem was a little jerkiness every once in a while, so I figured I'd get reclock to try to smooth things out.
It wasn't perfect - still some little snags sometimes - but in general it was working great.
So, last night, we went to fire up our first official bluray rental, Iron Man. And about 6 minutes in, I got *HUGE* sound desynch - 1500ms - and a jitter reading in MPC HC that matched the desynch. It seemed to be dependent on the position in the movie; at the same point in the movie the jitter and desynch was always the same. It'd range from 5ms to 1800ms.
I tried switching players (normal MPC, KMPlayer) with the same result. I tried rebooting; same result. I tried turning reclock off; same result.
I even got desperate and tried PowerDVD (!!) and, instead of 1600ms jitter/desynch sometimes, it had 300 to 500ms ALL the time.
Finally I uninstalled reclock entirely, and rebooted. I tried a new version of ffdshow to run in zplayer and regular MPC (the old one crashed whenever I skipped around in the movie), and it worked great, but only in French and Spanish - those were the only two stream selections available!
I tried some different renderers in MPC HC - VMR7, 9, windowless, renderless, windowed, yada yada. They synched fine, but had other strange problems (EVR worked until you skipped around in the stream, and then played audio but alternated between the two last-rendered frames continually).
Then, for the hell of it, I tried Haali again, and it worked - no jitter, no desynch. WTF?
Any ideas what's up here? I think I've relayed the relevant info, but I'm still not sure whether it was reclock that's the problem, haali, or some combination of things. Unfortunately I've only got Iron Man and WallE to test with... Thanks in advance!

Sounds like totally normal HTPC BS, if you ask me! 
I had lots of synch issues for a while too...not sure what solved it either, perhaps it was ffdshow audio decoder, I don't remember.

WRONG ANSWER! WROOOONG ANSWER! 
Yeah. If I had the money, and someone made nice simple box with a way to play/rip BDs and have detailed gamma and video mode settings, I'd be all over it.
But I don't have the money, and I don't think there's anything that can do all that anyway. So here I am.
It's kinda frustrating... once I got it to play, it was abso-freaking-lutely GORGEOUS! There must be a way! *grnnnnngh*
Oh well. Any more tips are appreciated...

Gamma works. Not sure what other options there are that render in a way that's 'affected by' gamma settings, at least on an ATI card.
Oh hell no. XP.

I don't think so, but I'm not 100% sure what MPCHC is using. It's not using ffdshow now, which is the only thing I really have much experience with (use it for DVD playback).
Some time this afternoon while my wife is working, I'm going to set my son practicing crawling in the HT, and check out the setup with fresh eyes to see if I can find any useful information. He can go backwards, but not forwards yet.

First of all...get Vista, it's better.
Second...just right click on the screen and select "filters" it will show you what it's using for the material you are watching.
Report back your findings good sir.

Seriously? Do you mean in general, or for home theater stuff for some specific reason?

Home Theater IMO, for crusing the web and running spreadsheets XP is fine. But I have to agree, my Vista HTPC is sooo much more stable and smoother then XP I wouldn't consider ever going back to XP.

Exactly...for HTPC, Vista is just better. Don't let the ridiculous rhetoric of people who don't even know what they're talking about fool you!

I guess that rules out the a-forum 'high end' section, then.
I'll check into Vista, I guess. I actually 'own' a vista license (at least, by rights - I bought a machine with vista on it and put QNX on instead. Probably technically OEM licenses aren't transferable, but I'm not going to lie awake at night if I... find an alternate source for reloading the OS. ). I can try it if I hit a brick wall, but...
...I went and checked some stuff. I had actually switched to VRM9 Windowed to get it to work, not back to Haali, which makes a certain amount of sense. (I was under some pressure... wife and best friend waiting, making comments about how the theater sucked and they wanted their money back...)
The decoder filter in MPCHC was ffmpeg, though it had a grayed out section for DXVA.
I tried both Iron Man and Wall-E, and they didn't desynch at all. But there was hella judder, even with my PJ running 47.953 (not 952... grr). So I figured, what the hell, I'll try reclock again.
Reinstalled reclock, fired everything up, and after one dry run with mpchc where it was juddery (I guess because reclock was figuring things out), it's been PERFECT. 5ms jitter max, and TOTALLY smooth, unlike with reclock / haali (which was mostly smooth, but would glitch at points). End credits are rock solid.
NOW the only thing biting my ass (at least, until I fix it, and something else imperfect pops up) is that it's behaving like it's interlaced. Reclock's reporting 1080i, and during smooth, fast pans, I can see what looks exactly like interlacing artifacts - when a telephone pole is scrolling past quickly enough, there are two of them. Pause, and it goes away - which is odd. And I swear to god I'm running 48p (though I suppose I should triple-check)!
Gotta check on that. Aside from that, though, it's tons better.
