Winamp 5.5.7 shows poor video quality

System data:

Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 3 (2600.xpsp_sp3_gdr.090804-1435)
Language: Spanish (Regional Setting: Spanish)
BIOS: Phoenix - AwardBIOS v6.00PG
Processor: Intel(R) Celeron(R) CPU 2.13GHz
Memory: 190MB RAM
Video card: VIA/S3G UniChrome Pro IGP - on board
Display Memory: 64 MB
DirectX Version: DirectX 9.0c (4.09.0000.0904)

Report:

I updated Winamp, from versiom 5.5.6.2512 to versiom 5.5.7.2789 first, to version 5.5.7.2792 later, and to version 5.5.7.2810 at last, clean installs without third parties plugins in each case, only to find a remarkable loose of video quality with respect to that of the version 5.5.6.2512, characterized mainly by colors biased to green-violet, low light contrast, lack of sharp boundaries, and vertical sweep lines, observed in streaming videos and local video files also.

Meanwhile, Windows Media Player 11 shows no video quality problems, and less streaming video lag than Winamp.

If I reinstall the version 5.5.6.2512 the video quality returns to normal, as it used to be.

I am just a plug-and-play Winamp user, not a Winamp expert who likes to tweak plugins' settings, and from my point of view Winamp 5.5.7 does not work as expected.

Attached please find a screen capture of a streaming video.

Please provide a link to one of the video streams which exhibits the problem.

We can't fix anything until we can reproduce the problem first.

(Don't worry if it says 'url submitted by user', mods & admin can still see the url)

Also attach your 5.571 "List of Plugins"
http://forums.winamp.com/showthread....161361#plugins

Hopefully, and at a guess, we'll then be able to make corrections/adjustments for your old video chip's inability to handle correct YV12->RGB conversion...

Thank you for your interest.

Attached please find:

* My plugin list, as requested.

* Screen capture.

Comments:

* Other multimedia plugins:

Flash Player 10.0.42.34

Shockwave 11.5.2.602 (full install)

* All video, either a streamed one or from a local file, has the same (degraded) features in versions 5.5.7x

* The problem arose in version 5.5.7

* Version 5.5.6 has no problem, video is perfect.

* Whatever changed, has changed in version 5.5.7

Seems the system does not admit more than one attachment...

Looks like your metafile.asx file is hosted on a server that's on our censored list.

Please retype the url and stick underline or bold vb code around a couple of the letters inbetween .tn and /metafile.asx

e.g. dom[ u]a[ /u]i[ b]n[ /b]

remove the spaces to make it work properly -> domain

Ok, I managed to get the stream in your screenshot...

mms://streamtn.uigc.net/tn

which plays perfectly for me (see attachment)

It's just a standard 256kbps WM v9.1 video stream (WMV 320x240 YV12)

Looks like our original synopsis was correct.

Some older onboard video chip drivers only do 16-235 instead of 0-255 for YV12->RGB conversion.

We should be able to workaround it (in the new D3D Renderer or nsutil) for the next release...

Though for now, your best bet would be to look for updated video drivers...

For your information:

I have updated the drivers of my VIA/S3G UniChrome Pro IGP video chip, from version 6.14.10.243 to version 6.14.10.380.

Seems Winamp 5.5.7 is working now (but Winamp 5.5.6 and olders worked with the old drivers), attached please find a screen shot.

Thank you again.

The old video renderer in 5.56 and earlier had workarounds for old drivers.
The new D3D Video Renderer in 5.571 doesn't... yet
(though the fix can likely be implemented in our nsutil.dll, which handles functions such as YV12->RGB conversion).

Or maybe the limitation/bug in your old video drivers didn't surface with our old video renderer but has been exposed by the new D3D one.

Good to hear that updating your video drivers fixed it for you though :-)

For your information:

This is to report that I could reproduce the problem in a Winamp 5.5.7.1 that I installed in a friend's desktop computer.

My motherboard is a Biostar P4M80-M4 and my friend's motherboard is an Asus P5VDC-MX, both equipped with on-board VIA display adapter chips.

As in my case, after updating the display drivers the problem disappear in my friend's computer.

Neither Biostar nor Asus have in their respective websites updated VIA/S3G UniChrome Pro IGP display drivers, which can be downloaded from the VIA Arena website.

I have the same problem and I have VIA/S3G UniChrome Pro IGP 6.14.10.223, but I can't update my driver.

Can someone help me?

You can download the drivers from the Via Arena website,

viaarena.com/Drivers.aspx?PageID=&OSID=1&CatID=1160

In my case I selected the link to "P4M800/CE/Pro UniChrome Pro" and downloaded the "P4M800Pro, P4M800, VN800 Display Driver" (Version: 22.00.01z; Release Date: Thursday, November 29, 2007; Supported Operating Systems: Windows XP, Windows 2000; Supported Chips: P4M800/CE/Pro UniChrome Pro, PM880, PM800, CN400 UniChrome, VN800 UniChrome Pro). Maybe it works for you.

Since your CPU is not powerful, and you use an onboard gfx card that has very limited graphics acceleration capabilities, most video rendering is done by the CPU. Therefore I'm not surprised you run into problems (not to mention you have only 190 MB RAM for XP!)

I'd recommend you get a $15 - $20 second hand ATI (AMD) or Nvidia card (and some RAM if you can afford it) and if you're planning to stay with that machine for long, it'll be the best investment you ever made.
