Patch to work with >=trasncode-1.1.0

I don't use this program, but I created a simialr patch for tovid (Bug 294492). Untested, As -V 420yuv is the default, I simply struck out the option entirely. 

-k has the same meaning in old version of transcode as it does in the new version of transcode so I donlt see why that would need to be removed.

Backport from mythtv CVS: let nuvexport work with newer ffmpeg

I can't figure out what version this snapshot corresponds to in the mythtv SVN, so I had to backport the patches by hand. Unfortunately, the snapshot on http://forevermore.net/mythtv is almost 2 years old, while numerous fixes to nuvexport to work with newer version of ffmpeg have been made in CVS in the last 10 months.

Patch ebuild to -r1

Patch to ebuild to apply ffmpeg and transcode patches to it and change RDEPEND to >=media-video/transcode-1.1.0 .

[Comment 5 daktak 2010-01-27 00:02:11 UTC]

If I don't remove the '-k' option for transcode, my videos end up with inverted colour.

Also had to change transcode.pm ".' -H 0 -x raw'" on line 243 to ".' -H 0 -x raw,raw'" so that the audio input is processed

Patch to supress the red/bleu swap "transcode -k"

Separate patch to suppress the red-blue color swap. Comments in the source indicate it might be needed for SVCD, and possibly others.

nuvexport was removed from tree with mythtv-0.21, please use the nuvexport from upstream instead. it's only a script, afterall.

and report your fixes upstream too, thanks!
