Choppy/Laggy HD Playback [MKV]

[manbearpig]

HD files has been playing laggy/choppy for a long time now. I have done plenty of research in hope to find a solution, but so far just one has had a result; change the video output to DirectX

However, this makes the windows colour scheme change to basic each time I run VLC, and is just as annoying as having choppy video.
Other things that I have tried (with no result) in both in VLC version 2.0.5 and 1.1.11: Change the caching value, enable/disable accelerated hardware, change in-loop deblocking filter to All.

Videos was playing smoothly in VLC a few months ago, and there is noting wrong with the file, as I get this problem with most videos now, from either of my hard drives. In my frustration I got an new high-end graphics card, reformated the system, and installed every thinkable update - and the problem still remains. Audio is still going perfectly in VLC. Windows Media Player plays said video and audio files perfectly, and so does Media Player Classic.

My system spec:

Windows 7 64 bit
Intel duo core 2.93 ghz
AMD HD 7870 graphics card
4gb ram

Someone please help me, VLC has always been my favourite player, and I wish to keep using it.

[Lotesdelere]

Please open Tools -> Messages (set Verbosity to 2) before you start the playback and then paste the full resulting log here or on Pastebin.com if it's too long.

But this

Videos was playing smoothly in VLC a few months ago

makes me think that something wrong happened on your system.

[manbearpig]

I don't think something has gone wrong with the system since the problematic files in VLC still plays like they should with WMP and MPC, but I am not excluding the possibility, I would like to know what may be the fault in such case.

(Please note that I made it full screen, because the choppiness becomes most noticeable in full screen on my second monitor. It is connected via HDMI to the graphics card)

Because it's about MKVs, and you said it worked before, then it might have something to do with this:
viewtopic.php?p=362836#p362836

[manbearpig]

Thank you for the tip. I tried to check dummy elements and force ffmpeg threads to 1, respectively, and restart vlc after each change, but still no effect. Mkv files still play sluggishly as if the system is overloaded.

I start to feel like I'm a lost cause. My problem might be special and unfixable...

[Lotesdelere]

Please upload a short sample of a problematic file to either http://streams.videolan.org/upload/ or to EmbedUpload.com, the latter will upload the file for you to several other hosts and then post the link to the file here.

Cut it with DGsplit and read here about how to do it:
viewtopic.php?f=14&t=57724&p=193335#p193335
50 MB max should be enough.

I can't reproduce the issue, even on a 5 years old computer and using software mode only.

Does it work better if you turn the subtitles track off ?

Do you have an ASUS motherboard ?
If so then try to turn the EPU engine off.

[manbearpig]

I have an ECS G43T-DM1 HDMI mATX motherboard. Disabling subtitles or audio did not improve.

Also, in that file in particular, it takes a very long time to make jumps in the video. It just stand still for a while, seemingly doing nothing, and later it plays again.

Edit: This also only happens in VLC, and not with MPC or WMP.

[TypX]

the latter is a bug fixed in 2.0.6+, either get nightly build (http://nightlies.videolan.org) or tools->preferences->show settings = all then demuxer->matroska->check enable dummy element save and restart vlc.
If you do the dummy trick please disable it as soon as you get a new version of vlc since it behaves badly with broken files.
For your problem, beware of the different "hardware acceleration" options. The one you are looking for is not the "accelerated video output" in the video thumbnail but the "GPU accelerated decoding" in Input & codecs. In your logs the GPU decoding seems not activated.

I think that did the trick, thank you very much for your help, you too Lotesdelere. Rather than risk messing it up with settings or try experimental version of VLC, I will just keep it as-is for the next release. I will tell if further problems appear.

[manbearpig]

Ok, I regret saying that it was playing fine, because now it is back to being absolutely horrid again... I really have no idea what is going on...

Currently everything is set to the defaults, except GPU accelerated decoding being on.

[manbearpig]

Pardon for triple post, but I made a new discovery. The problem still remains, though.

I am using two 1920 x 1080 screens. The primary desktop screen is a generic 24" LCD computer monitor by BenQ, connected via DVI to the graphics card.The second screen is 42" Phillips LED (LCD) smart-TV, connected via HDMI, also to the graphics card. No other physical wiring is supported.

Anyway, so the screens are different, but they have the same resolutions and aspect ratio (16:9).

Here is the interesting bit; When I'm using the TV-monitor to watch a video on the hard drive, it seems to work fine as long as the aspect ratio is anything else than 16:9. So if the file was shoot in 16:9, it lags. Or if I play a different file which were shot in a different aspect ratio (say 1.85:1 for example) and crop it to 16:9, it lags. I have tried this with .mkv, .mp4, and .avi files - all react in this way, and enabling or disabling GPU accelerated decoding makes no difference.

But this only happens on the TV, not on the desktop monitor, which seems to run everything fine. If I disconnect the desktop monitor and just run the TV, everything plays as smooth as it did on the desktop.

... any ideas? As I said before, things used to be fine.

[TypX]

This sounds like video driver issues and bad HDMI handling...

[manbearpig]

My video driver is up to date. I guessing there isn't a problem with the HDMI, because 16:9 it works smoothly on both screens, with the same files, when using MPC. I wish it was as simple as an outdated driver...

I'm really sorry if I'm being obtuse.
