Monochrome and 10 bits avc encode

[James_C_5]

Hi All,

I would like to test avc encode with chroma only video.

I try to set ChromaFormat  = MFX_CHROMAFORMAT_MONOCHROME with high profile, but MFXVideoENCODE_Init returns MFX_ERR_INVALID_VIDEO_PARAM.

Does Intel support chroma only on avc encode?

BTW, does Intel still not support 10 bits avc encode?

Thank you.

Best Regards,

James

Hi James, 

Unfortunately MFX_CHROMAFORMAT_MONOCHROME is not supported by AVC encoder as well as 10bit.

Best wishes, 

Anna

Hi Anna,

I have another question regarding monochrome encode.

Does Intel support monochrome HEVC encode?

I try to set following parameters. It doesn't work, and MFXVideoENCODE_Init also returns MFX_ERR_INVALID_VIDEO_PARAM.

ChromaFormat  = MFX_CHROMAFORMAT_MONOCHROME

CodecProfile = MFX_PROFILE_HEVC_REXT

GeneralConstraintFlags = MFX_HEVC_CONSTR_REXT_MAX_12BIT | MFX_HEVC_CONSTR_REXT_MAX_10BIT | MFX_HEVC_CONSTR_REXT_MAX_8BIT | MFX_HEVC_CONSTR_REXT_MAX_422CHROMA | MFX_HEVC_CONSTR_REXT_MAX_420CHROMA | MFX_HEVC_CONSTR_REXT_MAX_MONOCHROME | MFX_HEVC_CONSTR_REXT_LOWER_BIT_RATE

Thank you & Best Regards,

James

Hi James, 

MFX_CHROMAFORMAT_MONOCHROME is not supported by HEVC encoder.
