VLC player - poor playing quality?
 
I've installed VLC from .tgz which I downloaded from linuxpackages.net. When I play some clip (avi, mpeg etc.) the quality is poor - video is blurry, it looks like "net" if you understand what I mean. In xine the quality is fine, but when it plays video it looks like it has problems opening it - skips frames, pauses etc. I don't know if the problem is with codecs, settings or xorg configuration. My video card is ATI Mobility Radeon x1600.

This is from the FAQ at http://www.videolan.org/doc/faq/en/index.html#id266631 I hope this helps.

Video is choppy


Your system might be too slow to decode all pictures. It might be that your CPU basically is not fast enough. It can also be that the subsystem is misconfigured/misdriven, this happens for example under Redhat Linux. Here are some elements to improve speed:

*

Turn on DMA on your DVD device, for instance:
o

Under Linux:

# hdparm -d1 /dev/dvd

o

Under Windows, go to the System section of the control panel, and go to the Hardware manager (it is sometimes in a separate tab, and sometimes, you have to go to the Advanced tab. Then, righ-click on your DVD player, and check the DMA checkbox.
*

Upgrade to the latest driver for your video board

If you are running Linux, you can additionnaly upgrade to the latest XFree86 version. If supported, check that the xvideo plug-in is effectively used with:

% vlc -vvvv

*

Stop other running applications...
*

Try disabling framedropping. Framedropping allows VLC not to decode some pictures when the CPU is overloaded, but can result in choppier playback under certain conditions.

Framedropping behaviour can be configured in the Video preferences of VLC.

I would try mplayer (it has more options as to video drivers and such).

The slackbuild works great:

I've installed mplayer and playing quality is excellent. I just have problem setting it up to play every video in 16:9 aspect ratio by default(I need 16:10, but there is no such option).

Thank You, guys!

If you run it fullscreen, doesn't it automatically resize to fit whatever screen you have ?

Remember to try out different drivers. For example, I find 'gl2' (if available) to give best video quality. And either ALSA or SDL for audio.

No it doesn't, I have to change it manually.

Then something like 'gmplayer -aspect 16:10'
