Issue in enabling both MFX_EXTBUFF_VPP_COMPOSITE and MFX_EXTBUFF_VPP_PROCAMP features in VPP

[Thushara_Jayakumar]

Hi,

I am using Media Server Studio 2016. I am trying to configure different parameters for sample_vpp which came along with the SDK. 

I am facing an issue when I have both COMPOSITE and PROCAMP mode enabled in VPP.

With only one image input, image controls like brightness, hue, contrast, saturation setting are working properly.

Sample command line:

./sample_vpp -lib hw -sw 1280 -sh 720 -scc nv12 -dw 1280 -dh 720 -dcc nv12 -pa_hue -180 -pa_bri 100 -i Fine_1280_720_NV12.yuv -o out.yuv

When enabling composite mode, along with other image control , the final output is not having any image properties changed.

Sample command line:

./sample_vpp -lib hw -scc nv12 -dcc nv12 -pa_hue -180 -pa_bri 100  -composite parameters.par -o out.yuv

parmeters.par:

primarystream=Fine_1280_720_NV12.yuv

width=1280

height=720
cropx=0
cropy=0
cropw=1280
croph=720
dstx=0
dsty=0
dstw=1280
dsth=720
stream=collage_512_384_NV12.yuv
width=512
height=384
cropx=0
cropy=0
cropw=512
croph=384
dstx=100
dsty=100
dstw=512
dsth=384
GlobalAlphaEnable=1
GlobalAlpha=100

Is this mode of operation not supported in VPP or this particular sample application is not handling this use-case.

Thanks in advance

Hi Thushara,

According to Media SDK Reference Manual (<install folder>\Intel(R)_Media_SDK_2016.0.2\doc\mediasdk-man.pdf) In composition mode the vpp skips any other filters. So you need to create separate session for brightness, contrast, hue, saturation and other filters you want to apply.

Best wishes,

Anna
