Video encoder capabilities

Hi,

I'm considering using i.MX 8M plus processor for video encoding with H.264/H.265 codecs.

Application will receive two uncompressed unencrypted digital video input streams 1080p60 through MIPI CSI-2 interfaces. Both videos should be compressed to reduce data throughput and transmitted out through 1 GE interface.

I'm wondering if Video Processing Unit in the i.MX 8M plus processor is capable to encode simultaneously two video streams?

Is there anybody who has hands-on experience with similar application and can estimate VPU performance and capabilities?

Thanks,

i.mx8mp has dual mipi csi, each one can support 1080p@60, but VPU couldn't handle two 1080p@60 steaming encoding, imx8mp vpu only can handle encoding up to 1080p@60,

Hi @joanxie ,

Could VPU handle simultaneous encoding of two reduced input video streams?

Say 2x 1080p30, or 2x 1080i30, or 2x 720p30?

Could this work?

Thanks,
