Poor 1080p playback...

[HannibalX]

Hey guys,

I have a large .mkv video file (7.7GB) that I am attempting to playback using Media Player Classic. It seems whatever video mode I use the playback is very choppy and freezes every ten seconds or so. Also the audio is way ahead of the video playback - but the audio playback also skips badly.

Looking at task manager during playback shows the CPU (both cores) at about 50% usaged and about 700MB of ram usage, give or take. I am using the onboard audio currently as my SB Live! bit the dust. The onboard audio is AC'97.

Any ideas on how to improve playback performance? My rig is in my signature.

Thanks,
PR

I should also include that I have attempted to play the file with WMP 10.0 and Zoom Player with the same results. I played with the rendering options on Zoom Player which produced different quality levels - even with the quality level on poor the playback skipping still existed.

Thanks,

Zoom player and WMP 10.0 = Crap or the codec your using equal crap that aren't multicore friendly

test file :

12GB + file MKV h246 1080p file test

System :
Windows 2003 (i use windows 2003 as my normal OS )
Intel Core 2 Duo reduced to 1.6Ghz
2GB DDR2 ram


BS player with custom codec
FFdshow Mepg-4 Video Decoder
FFdshow Audio Decoder
Haali Media Splitter

CPU usage :
25% 1st core average
15% 2nd core average

Ram usage :
80MB VLC ram average
493MB Total system ram average

VLC with default codec

CPU usage :
15% 1st core average
15% 2nd core average

Ram usage :
80MB VLC ram average
516MB Total system average
But usage a little more ram than 1st setup 🙂

VLC is using better multithreaded codec but i like BS player because of its interface.

Check the read and write speed of the hard drive the video is in, because it can be that hard drive is reading too slow for the video to run smoothly.


I recommend you download VLC and try that 1st.

Another thing if this 1080p video is 7GBish and its 2hr long then i have to say its a small video for a 1080p res so maybe the video it self is a bad quality.

The video is about 1 hour long (the new Top Gear episode).

I will give VLC player a shot.

Dude, do you have the right codecs installed? If u don't already have CCCP codec pack installed go download it now as it'll let u play just about anything:

If codecs aren't the issue then are you sure that it isn't just a badly encoded video? The first matrix HD DVD copy I played kept pausing on me as well but it turned out to be a poor encode (the silky smooth playback of my other blu rays & HD DVD's attested to this) and downloading a new encode sorted it.

Try some other HD encodes and see if they are also skipping!

Let us know if u get it sorted.

Yeah I have CCCP installed. I don't have any other 1080p media to test. I'll look around and see if I can find another video to test.

2 Things.


Its either a bad torrent.

Or WMP sucks, use VLC

Make sure you change power saving mode to Performance. I got big issues with HD-DVD playback when using balanced or power saver as power profile.
