According to this post (More Speed | OpenMV):
With firmware v3.6.4 I was able to stream 1920x1080 video at 10 FPS to VLC on my computer. Once we get double buffering support working we should be able to increase that to 20 FPS (and maybe higher by setting the readout window).
I’m using the OpenMV H7 Plus with the same firmware and same settings. When I run the rtsp_video_server.py example code, the serial terminal indicates that the FPS is about ~10 FPS. However, When I view the stream in VLC, the FPS is extremely slow, much slower than 10FPS. When I save the video and process it, the FPS is about ~2 FPS. There’s also a ~2 second lag in the stream. How do I enable a 1920x1080 VLC stream at 10 FPS?
