Hello,
When using the H264VideoDecoder::GetFrame API, and it seems the output VideoData color format is being overridden to always be YUV420 planar format regardless of the value passed into the Init function. I am passing in UMC::YUY2.
Also, when retreiving the data from the VideoData class in a composite format, should I use GetBufferPointer, GetDataPointer, or still use the GetPlanePointer API, even though this would not be a planar format?
Thank you,
Herrick

Hi Herrick,
UMC H264VideoDecoder will process YUV 420 or YV12 formats only, you may want to perform a format conversion outside the H264VideoDecoder.

Hi Tamer,
Thank you for the clarification. I have been searching the IPP docs for conversion routines from YUV420 or YV12 to composite YUY2 (YUYV 4:2:0), is it this?
IppStatus ippiYCbCr420ToYCbCr422_8u_P2C2R()
The doc says: "The destination image pDst can be three-plane or two-channel". I assume the two-channels referred to a composite image?
This is for use on rendering on a Mac, which uses the common YUY2 as a native formet so the API must exist.
Could you clarify this for me and point me to sample code?
Thanks,
Herrick

Herric,
You can check the following file the UMC sample code:
codec\color_space_converter\src\umc_color_space_conversion.cpp
It includes the code for different color conversion.
Thanks,
Chao
