HD video colors washed out
 
2 Attachment(s)
The bug report is attached, and a screenshot of the problem. I would attach the sample file, but it's about 100MB and my upload speed is quite weak.

This is driver 180.51.

The issue is the colors are messed up in Xv only for HD videos. I don't have bluray, this is only a file of a movie trailer in HD. The colors are fine on soft mode or opengl.
vdpau does not work, does not even show in "mplayer -vo help". XvMC does show on the list
Code:

Available video output drivers:
        xv        X11/Xv
        x11        X11 ( XImage/Shm )
        xover        General X11 driver for overlay capable video output drivers
        gl        X11 (OpenGL)
        gl2        X11 (OpenGL) - multiple textures version
        dga        DGA ( Direct Graphic Access V2.0 )
        sdl        SDL YUV/RGB/BGR renderer (SDL v1.1.7+ only!)
        fbdev        Framebuffer Device
        fbdev2        Framebuffer Device
        aa        AAlib
        caca        libcaca
        dxr3        DXR3/H+ video out
        v4l2        V4L2 MPEG Video Decoder Output
        xvidix        X11 (VIDIX)
        cvidix        console VIDIX
        null        Null video output
        xvmc        XVideo Motion Compensation
        mpegpes        MPEG-PES to DVB card
        yuv4mpeg        yuv4mpeg output for mjpegtools
        png        PNG file
        jpeg        JPEG file
        gif89a        animated GIF output
        tga        Targa output
        pnm        PPM/PGM/PGMYUV file
        md5sum        md5sum of each frame

but it does not work "mplayer -vo xvmc -vc ffh264 Dark\ Knight\ trailer.mov":
Code:

But are XvMC or VDPAU supposed to solve this color problem if they worked or is this another issue?

Re: HD video colors washed out
 
-vo xvmc only makes sense for MPEG-2 video decoded with -vc ffmpeg12mc

VDPAU isn't working because your MPlayer isn't compiled with VDPAU support.

To solve the color problem, you probably just need to adjust the hue/saturation controls either in MPlayer, or by running nvidia-settings.

Re: HD video colors washed out
 
I had no clue about xvmc or vdpau, I just installed this driver. Thanks for the reply.

I don't think the problem with the colors is mplayer related because it happened in every player that supports Xv, from Xine to VLC. I solved it, sort of, because I think it's a container issue since I muxed it into matroska mkv and the problem disappeared. Oh well, mov not too important to me anyways.
