Dear Sir or Madam,



BSP : Android (jb4.2.2_1.1.0)


There is a header information [SPS(Sequence Parameter Set)] in the H.264 data.

And there is vui_parameters in SPS(Sequence Parameter Set).

Then, there is video_full_range_flag of the element of vui_parameters.


The intended function of "video_full_range_flag" is to tell the decoder that the content is using the full video range (Computer RGB) and the decoder should not expand the range otherwise clipping will occur.



Is the FSL's H.264 decoder changing RGB<->YUV processing by the value of this flag?



If Q1's answer is No, is it possible to process in the YUV change by the value of the flag?


Best Regards,
