VDPAU: csc matrices

[crisalide]

Hi, i'm trying to do colors control but can't get it to work. I wonder what i'm doing wrong.
This code gives really wrong colors. Contrast and Hue seems to work as expected, but Brightness seems to have no effect and Saturation gives wrong colors, from black&white (as expected) to pure magenta.
Any idea?

static void vdpau_update_csc( vdpau_driver_t *this_gen )
{
  float hue = this_gen->hue/100.0;
  float saturation = this_gen->saturation/100.0;
  float contrast = this_gen->contrast/100.0;
  float brightness = this_gen->brightness/100.0;

  printf( "vo_vdpau: vdpau_update_csc: hue=%f, saturation=%f, contrast=%f, brightness=%f\n", hue, saturation, contrast, brightness );

  VdpCSCMatrix matrix;
  VdpProcamp procamp = { VDP_PROCAMP_VERSION, brightness, contrast, saturation, hue };

  VdpStatus st = vdp_generate_csc_matrix( &procamp, VDP_COLOR_STANDARD_ITUR_BT_601, &matrix );
  if ( st != VDP_STATUS_OK ) {
    printf( "vo_vdpau: error, can't generate csc matrix !!\n" );
    return;
  }
  VdpVideoMixerAttribute attributes [] = { VDP_VIDEO_MIXER_ATTRIBUTE_CSC_MATRIX };
  void* attribute_values[] = { &matrix };
  st = vdp_video_mixer_set_attribute_values( this_gen->video_mixer, 1, attributes, attribute_values );
  if ( st != VDP_STATUS_OK )
    printf( "vo_vdpau: error, can't set csc matrix !!\n" );
}

That's a bug. A fix has been created, and will be in a future driver release. Thanks.
