Is there any way of controlling the brightness/contrast etc. of video playback? Unfortunately at the moment I'm having to use Windows Media Player to view some stuff because of its ability to do this, and I'd really rather not have to.

the brightness/contrast ...

Good idea, good, verygood ...

I'm guessing that this means: 'I'd like this information too'. Am I right?

There probably will be a limited support of such in version 12.

You could install the FFDShow filter pack. Its controls are far better than what WMP has.

Some information is here (47 forum pages): http://forum.doom9.org/showthread.php?t=98600

The latest builds for different processors are here: http://kurosu.free.fr/ffdshow.htm

Some good, a bit older builds are available here:

For P4:

For P3 and AMD:

FWIW, all AMD Athlon64 Processors (for both Socket 754 and 939) support SSE2, and many of the newer ones (Revision E and later starting with the Venice and San Diego cores) also support SSE3.

I personally have had trouble with many of the newer experimental builds (though I hadn't seen or tried many of those).  I may check them out, but for most purposes the Alpha build on the Sourceforge page are fine.

If you aren't sure if your processor supports some specific version of SSE (or any other x86 extension) you can use CPU-Z (a great free hardware ID app) to find out for sure.

Thanks a million AlexB and glynor!   

I installed ffdshow; it's a very comprehensive program - I don't understand more than half of it, but it did what I wanted. Being able to auto-load on particular filenames is great!

I haven't played with the Audio section - do either of you use it? What's it good for? I'm usually happy to leave things the way they are when it comes to audio - unless I play around with a particular file in something like Adobe Audition...

I wonder if anyone fully understands the available options. I have learnt them on the need basis. I have never had time to experiment all possible combinations.

The defaults are fine if you don't need anything specific and everything seems to work. However, especially with a home theater setup tweaking the options may improve many things. The Doom9 forum is a good place for more information. Also, AVS Forum has many interesting FFDShow threads, like this one: http://www.avsforum.com/avs-vb/showthread.php?t=469464


glynor,

thanks for the AMD details. I just copied the links from my old link list. My AMD knowledge is a bit outdated since I have used only P4 recently. The Sourceforge 2004-10-12 alpha builds you mentioned are fine and probably stabler, but they lack a few recent gimmicks. The 2005-11-20 SSE2 build from Afterdawn has been fine on my P4 PCs.

I thought I'd mention that after QUITE a bit of searching through this thread at Doom9, I found this page where some kind soul posts all the different builds of FFDSHOW for a wide variety of different platforms (with handy changelogs).

Included are builds specific to AthlonXP (with SSE1 and 3DNow support), P4 (SSE1 & SSE2), P3 (SSE1 only), Prescott (SSE1,2,&3), and Athlon64 (SSE1, SSE2, & 3DNow).  So far there's no Venice-specific Athlon64 build, but I would imagine it's only a matter of time (probably once AM2 comes out when there will be a nice line as to which Athlon64 processors support which extensions).

So, if you feel like living on the bleeding edge of FFDSHOW builds that's a great place to look.
