Support for 10-bit YUV format. #251

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Would you make NEON optimized conversion function from 10-bit YUV420P to RGBA 
or RGB565 ?
10-bit YUV format is increasingly used especially in encoding animation.

Sorry, this is not a defect. but I couldn't find a way to change issue type to 
'enhancement' or anything else.

(sorry for slow response... I was away)
Changed to enhancement.

I've got 3 concerns
1. testing - do you have test content?  please attach
2. support priority - how common is 10 bit?
3. ease - does current implementation internally lend itself to 10 bit.  I 
suspect it does for neon and C but not SSSE3.
I'm thinking 10 bit is yuv420p is stored in upper 10 bits of 16 bit unsigned 
channels, but if not, that complicates ease of porting.

Do you have a fourcc for the specific 10 bit format you have in mind?
Or very detailed description and/or sample data for it?

Unable to proceed without details on format.  Closing for now.
Reopen if/when more information is available.
