Session count limitation for NVENC on geforce gtx1080

thank you for reading my question.

my goal is 5streams nvenc_hevc encoding in real time.
(720x480 30fps 3channels and 1024x1024 30fps 1channels and 1280x1024 30fps 1channels)

so I’m wondering that a geforce gtx1080 encodes 5streams in real time.

additional is available using cuda library like NPP?

I’m waiting for your response.

thank you.


GTX 1080, or all GeForce cards for that matter, can only encode up to 2 simultaneous streams.

It could have been helpful, if the maximal number of sessions was exposed via one of the NV_ENC_CAPS_ values.
