Encoding profileGUID

Hi Tim,

I noted NvPipe does not "touch" the encoder profileGUID. Allowing the user to setting it up can be useful for web-based clients since media source extensions need profile specification.

What is the encoder profileGUID NvPipe is using for H.264 ?

Thanks,

Benjamin

Hi Benjamin,

thanks for reaching out; this is a good question!

While NvPipe sets the preset to NV_ENC_PRESET_LOW_LATENCY_HQ_GUID, it does not touch the profile. This means that the profile will be automatically selected by the encoder.

You can manually override the profile in the Encoder::recreate method. It's the profileGUID property of NV_ENC_CONFIG encodeConfig.

The available profiles are defined in nvEncodeAPI.h, just search for NV_ENC_H264_PROFILE_BASELINE_GUID for instance.

Hope that helps!

Best,
Tim
