Hi PC gurus,
I'm having a few issues playing back 720p MKV files on my computer (might be other 720p files but I only have mkv). The sound plays fine but the video skips and jumps using VLC. My computer is:
CPU: Pentium 4 2.4Ghz
RAM: 2GB DDR2
Grapics Card: GeForce 4 Ti 4200 128MB (AGP)
OS: Win XP Pro
What can I do to improve the play back performance? Would upgrading the graphics card help? Or am I just asking too much from my computer?
Thanks
Robert

I doubt new gfxcard will help with VLC + mkv.

You could try download a quicktime HD trailer and running through VLC (Quicktime 7x eats CPU for breakfast on Windows, VLC is much better - HD trailers stuttered constantly on my Athlon XP 2500+, and ran 100% smooth through VLC - I had a Ti4200 64MB AGP at that point). It could be mkv, it's a format I rarely encounter.
CPU - P4 2.4GHz with DDR2? Are you quite sure about that? Not that it should make much difference in this scenario.

No, not really, but my computer is at home and I can't check, was about 60% sure.
Had not thought about QT trailers, will give that a go when I get home.
Is VLC the "best" player to use for Windows?
Thanks

VLC - I think so, yes, at least I haven't heard of anything close to it before. It doesn't do everything out there, but it does most of it.
About your RAM, if you hadn't said that you've got 2GB RAM installed, I would have suggested that it had SDRAM or DDR1. With 2GB I think it has to be DDR1, practically speaking.

I can play back 720p mkv container files just fine on my Atom 1.3 GHz CPU with i890 (?) gfx chipset. However, I need to disable post processing as it is really at its limit. I'm using the CoreAVC or DivX 7 codecs for H.264. MPlayer is far too slow for that to work at least on my machine.
-
Just wondered if there was anything more Windows based/optimized (as I though, probably wrongly, that VLC was very Linux based)?
Thanks

Try using GOMPlayer ... I've had very mixed results in the past with VLC Player
http://www.gomlab.com/eng (http://www.gomlab.com/eng/)
Also check the codecs you have installed ... they might be old and out of date. Here is the latest K-Lite Mega Codec Pack ...

In my experience, VLC runs better on Windows than Linux :)

Thanks guys. I will give them a try when I get home and report back.

Would a graphics card that, for example, supports PureVideo (http://www.nvidia.co.uk/page/purevideo.html) not help?

Not with VLC.

@piru
So if I use another video player (I really do not care which one I use as long as the play back it good) then a PureVideo / Avivo supporting graphics card would help with the playback of HD (720p) video files (as long as the codec used for the video was supported by PureVideo / Avivo)?
Thanks

Correct.

@piru
Thank you. Sorry for the (hopefully not too) silly questions, just not that up on PC graphics cards.
@thread
If the other suggestions do not work for me which do you think is better: PureVideo or Avivo? Opinions please!
Thanks

I have just tried playing a 720p trailer from apple.com in VLC and that played fine. Also tried playing the same file in VLC on Linux (Xubuntu) on the same computer and it played fine. Really stumped now. :(
Tried playing the file in Window Media Player after installing CoreAVC and the video plays fine, so does the audio but there is a lag from the video of about 1/2 to 1 second. So all the sound happens early. Also Gomplayer is worse than VLC.
What could the problem be with VLC on Windows? Also why the lag when using CoreAVC? Has anyone got any idea?
Thanks
Robert

For Win XP Pro I suggest CCCP (http://www.cccp-project.net/) (Combined Community Codec Pack) which includes Media Player Classic Home Cinema, it works great. This is officially endorsed by the Matroska Project, the people who brought you the MKV format.

@modrobert
Thanks for the recommendation.
@Thread
I just tried CCCP and Media Player Classic that comes with it and I still get the lag with the video. :(
Thanks

What kind of lag?
I got some stuttering so every now and then, but that's because I think my harddisk is dying
-
The audio is about a second ahead of the video.
Thanks

get kmplayer for windows (not the linux one with same name)
it has its own codecs (like mplayer) and its highly configurable. you can use the 'low speed' preset.
it doesn't even need installing/messing_up_registry, just unpack it somewhere
-
@orange
Thanks for the suggestion, but I still get the lag when playing it with Kmplayer.
Thanks
Robert
-
well the only thing left is mplayer... if you aren't bored by now ;)
it also has its own codecs and doesn't need installation.
however it lacks usable GUI (there are various, but I couldn't find a decent one)
it seems to me like the fastest possible player out there
I'd also suggest defragmenting the HDD partition that holds the movie and killing unneeded processes/services
-
Make sure you set it to allow dropping of frames (not hard frame dropping if you can help it).
Also, is it just with one mkv file in particular or many?

l answer about the graphics card as l have one these too , if you update to 6600 or even better the 7800 both cheap second hand you game play be way better l noticed this with half life 2 .
l also tryed to run xbox360 hd dvd addon through xp and p 2.6 p4 oh is it hypewr treading whould help it whoudint really play on this set
l tryed on my nephews dual core e7300 cpu and gforce 9600 went so wel so maybe upgrade your system
also you chould try tversity software thats if you have xbox360 or psx3 and just stream vids to your tv much easier music and such also
hope this is some help the p4 set up you have is still fine though l have 2 such systems
add extra ram helps and your ram should ddr 400

I use the KMPlayer in my windows machine along with CoreAVC and nVidia Cuda hardware acceleration. It works like a charm to watch h.264 files... CoreAVC is suposed to be the fastest and most optimized set of codecs outhere. For CUDA you need a recent gfx board though...
If you use TheKMPlayer and CoreAVC I think you still need to configure KMPlayer to use the CoreAVC codecs.
Hope that helps.

Thanks for all the replies.
I have just done a clean install of Windows XP (Home as I could not find my Pro disc). The problem still persists with VLC. I'm starting to wonder if it is a problem with the file. I do not have any others to test. Does any one know where I can download some other mkv files to test?
I was probably not using the right word when I said lag, as the video plays smoothly and the audio plays smoothly too. It's just that they are about a second out of sync.
On the graphics card side of things I can get either an ATI Radeon HD 3650 512MB or nVidia GeForce 6 6200 256MB. What are you opinions on these? Which would be better if I were to upgrade?
Thanks

Hi,
While playing back the video, open the windows task manager and select the Performance tab and monitor the CPU usage .. is it maxed out (or close too) most of the time?
It's been a while since I setup my HTPC but I don't think you can rely on a new HD video card helping with a lot of the MKV films.
I'm not saying it won't help, i'm just saying it may work for a lot of mkv's.
Hope you get it sorted!

Yeah sure is, 95%+. :( Guess that means upgrade time!
Although I have just gotten hold of another mkv. This plays fine at about 90-100%. The only difference I can see between the 2 files is the frame rates. The one that does not play is 29.970628 (as reposted vix VLC) and the other that plays fine is 25. Guess this could just be a dodgy file! :madashell:
Just a quick though a bout upgrades to my computer. What would be the best thing to upgrade? I can only get another 512MB of ram in it.
Thanks
Robert

Upgrading the ram wont do much with this problem. You have to upgrade the cpu and i am not sure it will be worth the upgrade unless you also upgrade the mobo.
-
toca180,
Some encodes/releases are crap and out of sync, that's just normal (unfortunately).
Click on the "Show extended settings" icon on the lower right in VLC, choose the "Synchronization" tab and adjust the "Advance of audio over video" to sync it.

If you want to be able to playback 720p without worrying you're gonna need:
A new CPU and Motherboard! And the new motherboard may not be compatible with your RAM so probably new memory. Hmm, you may need a new pci express video card too( if yours is AGP )
A nice Core2Duo would be ideal but most dual core Intels or AMD cpu's should be fine for 720p.
If your on a tight budget the older Dual core chips can be had quite cheap.
check out http://www.scan.co.uk/todayonly/
If you want 1080p in the future then you need to look at something like a Intel E8400 or whatever AMD's equivalent is these days :)
oh, the 30FPS and 25FPS will just be because one is NTSC and the other PAL
-
Thanks for all the help guys. I guess I will just have to live with it or up grade. Snow Leopard just can out and Windows 7 is round the corner, guess it could be a goof time got me to look at least.
Another though, I could just stick to SD video! That has not done us all so badly over the last few years! :afro:
Thanks again for all the help and suggestions.
Thanks

@ toca180,
your system is woefully underpowered. As Hektic pointed out - you need to upgrade. And if you're upgrading you might as well go for 1080P playback for the little extra it would cost.
I built my system some months ago: Gigabyte mobo, AMD 6000+ dual core, 4Gb memory, GTS8600 and an LG Blu-ray/HD drive. Plays 1080P flawlessly. Without the drive you should be able to upgrade for around £150-£180.
