adding ffmpegcolorspace element supplied by Ronald after cleaning

up and pulling in the right bits of upstream source.
|

I'm sure a better C/compiler wizard could do some cleaning up (for
|
||||
example use GLIB's malloc stuff), but as a first pass this
|
||||
works very well

|

* When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
|

* image data is stored in AVFrame.data[0]. The palette is transported in
|

* AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
|
||||
* formatted the same as in PIX_FMT_RGBA32 described above (i.e., it is
|
||||
* also endian-specific). Note also that the individual RGB palette
|
||||
* components stored in AVFrame.data[1] should be in the range 0..255.
|
||||
* This is important as many custom PAL8 video codecs that were designed
|
||||
* to run on the IBM VGA graphics adapter use 6-bit palette components.

i (michael) didnt check them, these are just the alignents which i think could be reached easily ...
