Does i.MX6DQ VPU support 4:0:0 (Monochrome) for h.264 high profile?

[satoshishimoda]

Hi community,

I have a question about i.MX6DQ VPU.

Please see Table 69-1 in IMX6DQRM Rev.3.

It says h.264 decoder supports HP (High Profile).

According to "Feature support in particular profiles" table in the following site, high profile supports "4:0:0 (Monochrome)".

https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

Then, do i.MX6DQ VPU and Linux BSP (L3.14.xxx) support "4:0:0 (Monochrome)"?

Best Regards,

Satoshi Shimoda

Yes, the i.MX6DQ VPU decoder can support Monochrome format in the H.264 High Profile stream. However, the decoder's output format is always 4:2:0 for all profiles/codecs. In case of Monochrome stream, a fake (zeroized) color components will be output.

Have a great day,
Artur
