More transcode parameter changes

[Marc Randolph <mrand@…>]

Per ​http://hg.berlios.de/repos/tcforge/file/d6956f8dca76/docs/CHANGES-1.0-1.1, the 1.1.x released branch of transcode has done away with the "color" argument and replaced it with --log_no_color

The --use_rgb (aka '-1') option has also changed again (this was touched recently in Bug #6807). Confusingly, mtd/jobthread.cpp put this option on the command line when "use_yv12" is set in mythconverg, which causes transcode to use the CODEC_RGB. This is confusing because comments within transcode source refer to RGB as something different than YV12.

If we really need this option, it has been replaced with "--video_format rgb24" Removing this option altogether will change transcode to use the default setting of yuv240p.

Unfortunately, their changes are not compatible to older versions of transcode which most people are running right now (but distributions are moving to the new one this fall), so changing it could create backward compatibility problem for those that don't upgrade their version of transcode - hence this patch which adds a option to the configure script for the newer versions of transcode.

If patch is adopted, it requires re-running configure regardless if you are on old or new transcode (to generate the config.h).

If it is preferred to try to auto-detect the version of transcode that is installed, I could take a stab at that.

Adds configure script option to allow for newer versions of transcode to work

Mark,

For a transitory upgrade, I don't think changes to the configure script are a good idea. mythdvd either needs to detect the running version of transcode, or this needs to be postponed until most distros are running the new version of transcode.

(In [22358]) Fixes #7279. Fixes #7203. Update mtd to support command line commands for transcode versions 1.0 and 1.1. Fix colorspace issues. I was able to create correctly colored transcodes with both versions. If anything is still amiss, please open a new ticket with log output from mtd.
