MKV/mp4 video lags out of sync but audio is fine
The problem is that the audio is playing at normal speeds, but the video slows down so the audio becomes somewhere around 5 seconds ahead usually. Just to clarify, the video doesn't stop or cut out, it just slows and everything gets out of sync. Before I used to have this problem with only mp4's but I haven't watched an MP4 with that problem in a while.
I've noticed that the files with AAC in the file names have a higher tendency of experiencing this problem. My system specs are Processor: AMD Turion(tm) 64 X2 Mobile Technology TL-50 1.60 GHz 2 GB RAM 32-bit operating system Windows Vista 50 gigs free memory I have CCCP and Media Player Classic installed and I've reinstalled and reset settings for both countless times. For examples of this problem, Mazui's ep 2-4 of Angel beats has lagging audio. Filter 0: Default DirectSound Device Filename: quartz.dll Filter CRC: CRC Unavailable. Date: ERROR: File Not Found.

Sounds like a standard "your computer is not fast enough to play this stuff" kind of a problem. You might try resetting your CCCP settings and turning on multithreading in the CCCP's settings app if you're running the current stable. You can pick it from the place in the settings app where you can also turn on and off H.264 decoding, it's the "MT" selection -- it should also become used automagically in the next release, should a multicore CPU be detected. Also, most of your MP4 problems should go away with the newest beta (linky) because of the updated Haali splitter.
Personally I'm running the 04-07b beta at the moment, but I'll be updating in a moment. And, looking at the changelog, I'm not seeing anything that I'd think would break really badly... although you never know, you might end up blaming movax! Of course, in such a case you can usually just revert to your last known working revision. P.S. I actually used to have a laptop with the exactly same CPU. With CoreAVC and XP I had performance to play back H.264 up to 1440x1080 with overlay, and up to 1280x720 with a decent renderer, such as Haali's. So yeah, with Vista you would have EVR-CP, which most probably would be slower than the overlay performance I had. Not to mention if you're running a single-threaded decoder, like the case is with ffdshow's default settings with the 09-09-09 pack.

Wow that's really disappointing. Seeing as this computer is 4 years old I would expect it to be able to play mkv files...but I can't find anything that says MT or mutlithreading in the settings of the CCCP settings app. I have the one from the site dated 9/9/09 though...
oh and on the beta page the first thing they said is don't use it if you don't know what you're doing...and i don't so i'll pass on that :\ but thanks for replying |

damn it. now I have the audio drop problem but it seems to sync fine. rather than audio drop, it's like the whole thing just pauses and then plays again. I think there was another post with that problem so back to forum hunting!
Turned on MT and dynamic range compression (because it sounded like a good idea) and now everything syncs fine. Well the OP cuts out every once in a while but it's w/e do I delete this topic now? Last edited by Validictus; 2010-05-01 at 19:35. |

I would wish ATi/AMD would open up some straight APIs for their decoders as well :V Just like nvidia does with their video decoding API (that is inside CUDA, but really isn't CUDA because it just calls the VPx chip for decoding and feeds it data).

AMD/ATI handling of GPU decoded video seems to be kind of messed up anyway. I am having trouble enabling it on my laptop which has a Mobility Radeon 5650... weirdness is happening when I do it. But my CPU (Core i5-430M) is strong enough to eat 1080p BD rips, so I'm not overly concerned about needing GPU acceleration on 720p anime fansubs.
