STM32N6 H264 Video Encoding

Hi, I am wondering if anyone has had any experience using the STM32N6 onboard H264 encoder? I am trying to write a business case for using this MCU, which claims it can broadcast H264 video at 720p & Audio at a stable 30fps over LAN without any noticeable drops in performance? The only solutions I have found so far have been dedicated SoC.

For a business case, it's better to validate the complete pipeline using VENC_RTSP_Server rather than benchmarking the encoder alone. Measure sustained 30-fps operation, frame drops, end-to-end latency, CPU load, memory bandwidth, and Ethernet utilization.

Hello ​@Link_P 

ST provides a reference RTSP server application for STM32N6570-DK that streams H.264 video and optional audio over LAN.
