Dear Sir or Madam,

 

Hello.

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.

 

[Q1]

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

 

[Q2]

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

 

Best Regards,

Keita
