Why Do my MKV Movies play Choppy in Winamp?

[caliphornia]

hey guys,

so i downloaded an MKV codec pack today, and i'm watching a movie in high definition (it's an mkv file) it runs perfectly smooth in all media players except for winamp. winamp makes it have a very low framerate for some reason. does anyone know what the problem is?


btw, it's not a problem with my PC (i have a high end PC) it's a problem with winamp... the movie runs smooth in WMP and all other players and they're all using the same codec pack...

what mkv codec pack?

ffdshow with haalis matroska splitter?

[caliphornia]

yea those are the ones i have

Was a solution ever worked out for this problem? I am experiencing the same problem. I'm running the CCCP Code Pack and the Haali Splitter and .mkv files sieze up during playback.

Sorry to bring this back from the dead, but I'm having pretty much the same problem - anyone found a solution yet? The CCCP runs pretty well in progs like Media Player Classic, but somehow Winamp doesn't seem to like hi-res mkv's...

I've noticed that Winamp's CPU usage is lower than the others' during playback - maybe that has something to do with is? (MPC pegs one of my cores at 100% most of the time without stuttering one bit, whereas Winamp hovers around 80% on that core, and the video pretty much grinds to a halt if the usage hits 100%)...

Any ideas?

I also have this problem (low FPS and very slow and choppy playback), but today i found a workaround! The 5.1 audio stream seems to be the problem. The 5.1 videos i tried all have AC3 audio. AC3Filter is my default AC3 decoder.

The steps to "fix" it:
-Download Directshow Filter Manager* and run it.
-Select AC3Filter and press the Show filter properties button.
-Press the Filter settings button.
-Change the Output from AS IS(no change) to for example 2/0 - stereo or any other.
-Apply the changes and play a video with a 5.1 audio stream.

The video now plays just as smooth as all the others, with normal FPS and no choppy playback. When i use the same splitter+decoders in another player (i tried The KMPlayer) there are no problems. My pc is fast enough (core2duo E8400 cpu). Tried avi and mkv videos.

Can someone tell me if this is a Winamp bug? Please reply so i can report it.

I've edited the url into Sjakko's post, though you don't need to install the DirectShow Filter Manager.
Just go to: Start -> Programs -> AC3Filter -> AC3Filter config
and change the Output there.

I already had mine set to "3/2+SW 5.1 channel" & "PCM 24bit"
and have never experienced any problems
(though you can try "2/0 stereo" & "PCM 16-bit" or whatever if you want)

Alternatively, you could use latest FFDShow for AC3 instead...
Start -> Programs -> ffdshow -> Audio decoder config -> Codecs page,
set AC3 to Liba52
(probably requires you to disable use of AC3Filter first in AC3Filter -> config -> System tab)

I too an having the juddering/choppy problem. I have tried all the above and still the problem remains..

Has anyone tried the comments above?? Has it worked for you??? Does anyone recommend i try a different way??

I have ffdshow and on the above advice, ac3filter too...
Would also note that it works ok in windows media plopper and that the audio is fine, its just the video thats choppy


Thanks
