Using both video encoder cores?

Hi Everyone, I have a code which instances NvVideoEncoder twice so that two separate image streams can be encoded. Are both cores used automatically under the hood or do I have to tell NvVideoEncoder to do that manually? I want to make sure the encoding is done in parallel for the two streams.

Thanks,
Dave

Hi,
The engines are enabled automatically. Please execute sudo tegrastats. If two engines are enabled and running, you will see NVENC and NVENC1.

Thanks, seems like they are both enabled as this is what tegrastats reports:
