Log Message:
* Add support of yuy2 to emotion_xine module. So now, we can play wmv
movies!
I had to make some module API changes:
- rename yuv_size_get to video_data_size_get
- add the function "Emotion_Format (*format_get) (void *ef);" in
Emotion_Video_Module. This function should return the format used by the video
(EMOTION_YV12, EMOTION_YUY2 or EMOTION_BGRA).
I use a yuy2->bgra converter since evas doesn't support YUY2. This converter
should be rewrite since it's really not optimized and since it is under GPLv2
(emotion is under BSD). I added an explicit comment above the function for
that, but it'd be better to use a converter under BSD.
If it's really incompatible with emotion license, I will remove it.
