Hi
I have been working around 420, 422 YUV chroma file formats. I have 2 queries.
1. Is there any registered format for 422 chroma format for planar mode. I have used the packed mode it is working fine. Do let me tell if there is any and how is to be used.
2. Is there any registered format for 444 chroma format for planar or packed mode. I have come around one namely AYUV. If it is what is chroma format YUV 444 support then how should it be handled. What is the alpha value in this? How will you handle this AYUV.
Waiting for a reply
Regards
SHAH

Here are the formats currently supported:
SDL_YV12_OVERLAY /* Planar mode: Y + V + U (3 planes) */
SDL_IYUV_OVERLAY /* Planar mode: Y + U + V (3 planes) */
SDL_YUY2_OVERLAY /* Packed mode: Y0+U0+Y1+V0 (1 plane) */
SDL_UYVY_OVERLAY /* Packed mode: U0+Y0+V0+Y1 (1 plane) */
SDL_YVYU_OVERLAY /* Packed mode: Y0+V0+Y1+U0 (1 plane) */

You're welcome to add support for any additional formats that you like.

See ya!

I know these are from man pages from Linux or some website. What I need is the support for YUV Planar 444. and planar mode for YUV420 which have been implemented.
