Not able to find UVC Streaming Code #2

Open Ritesh236 opened 3 years ago

Ritesh236 commented 3 years ago

Hello Team,

I have checked whole code including main.c file but didn;t find streaming or image capture code.

So, is it somewhere else as I have compiled it for STM32F429ZI board?

Regards, Ritesh Prajapati

This will stream an image over USB using the UVC interface. It currently is setup to stream a static jpeg buffer but add camera capture code and you will have a streaming camera. I have been able to stream ov5640 sensor at 720p jpeg compressed stream from the camera sensor over UVC (USB2.0) at 24fps without any issues.

STM32F7 USB HS Composite UVC device streaming video from Quad spi rom over UVC isochronous endpoint to the host at 25 fps and receiving video from the host via a command line utility over a bulk display endpoint at 20+ fps (limited by the jpeg decoder, should be able to get closer to 30fps in the future). All frames are jpeg compressed to reduce bandwidth requirements. HS USB is running ~ 100 mbps .
