[vlc-devel] [PATCH] Fix a problem with outdated Video4Linux2 headers.

[Andreas Schwarz]

Hi everyone,
On some kernels, the compilation of libv4l2_plugin_la-video.lo fails, because 
of outdated Video4Linux2 headers. This patch attempts to fix this.

The headers in question are:
V4L2_COLORFX_NEGATIVE
V4L2_COLORFX_EMBOSS
V4L2_COLORFX_SKETCH
V4L2_COLORFX_SKY_BLUE
V4L2_COLORFX_GRASS_GREEN 
V4L2_COLORFX_SKIN_WHITEN
V4L2_COLORFX_VIVID

It occured with a 2.6.35-25 kernel on Ubuntu 10.04 x86_64.
 
 More details here:

Cheers

Andreas
