The VideoLAN Forums

Vlc plays these types of videos terribly. I have coreavc installed and mlc seems to run these videos just fine. (except i cant find colour controls) with video lan the playback is extremely laggy.

Buy a faster computer or help ffmpeg people to imporve the H264 decoder.

theres nothing wrong with my computer. and my brothers is identical to A T and it runs them smoothly and fine.

also video lan doesnt use the x264 codec. theres no option anywhere to choose what codec to run the video with. im convinced it doesnt use them.

x264 is not a codec.
x264 is an H264 encoding library started and hosted by the VideoLAN project.
It is NOT a decoder

VLC media player uses only its internal codecs and not all those DirectShow Filters or those bigs packs. For H264 decoding, VLC uses FFMPEG H264 decoder, which is not multithreaded and slower that CoreAVC.
But it is Free AND Open Source.

If you have a marginal computer for h.264 decoding, you could try turning off the loop filter in preferences. The default is (none) ON. Set it to (all) OFF in the FFmpeg properties.

i have an amd3200 64 bit processor and a nvidia 6800 gt pci. i highly doubt my pc is "maginal" besides, like I said my brothers computer has the exact same specs and it plays them almost flawlessly, actually my computer has 4 gig of ram and his has only 1. and my mother board is the SLI version of the same asus motherboard he has. Those are the only differences.

As was stated here your computer is marginal ad is totally dependent on the resolution of the file. You brother may be trying to drive you nuts by showing you a 480p or lower resolution and you are trying to do 720p or 1080p which would be a joke. Or you are trying to do an interlaced format that may or may not be supported.

nope same videos i downloaded them myself.
And he didnt say computers are a marginal factor in the performance of videos, he said MY computer was marginal implying it was sub standard for playing these videos, when that is not the case

Then I would suggest you have system problems between the two machines.

What happens if you try playing a commercial DVD and open your task Manager and look at CPU usage???

Where are the loop filter options? because its not under "FILTERS"

I turned an option on to increase cpu priority and that improved it, more than twice as good as it was before, but its still not very watchable.

The loop filter is located in: Preferences > Input / Codecs > Other codecs > FFmpeg. Click the “Advanced option” box at the bottom right corner of the preferences menu and change the “Skip the loop filter for H.264 decoding” settings to all.

Big improvement.. definately watchable now. And the picture looks just as good as before? presumably ive just lowered the quality in favour of performance? but i dont notice it anyway so its all good

you'll notice it only if you'll see it in a big screen
if you want to attach it to a big LCD you must buy a more powerful screen card

You can notice it also on small screen. The effect is more visible on smaller bitrates where post processing is more important for the image quality. And you don't any super display adapter to attach 1920x1200 or 2560x1600 resolution displays to computer.

And please, don't wake up old threads
