High-performance low-latency camera streamer for Raspberry PI's

camera-streamer

Use main branch for semi-stable changes, or develop for experimental changes.

There's a number of great projects doing an UVC/CSI camera streaming on SBC (like Raspberry PI's).

This is yet another camera-streamer project that is primarly focused on supporting a fully hardware accelerated streaming of MJPEG streams and H264 video streams for minimal latency.

This supports well CSI cameras that provide 10-bit Bayer packed format from sensor, by using a dedicated ISP of Raspberry PI's.

Take into account that this is a draft project, and is nowhere as complete and well supported as awesome ustreamer. This project was inspired by mentioned ustreamer.

Requirements

1. Debian Bullseye, with at least 5.15 kernel
2. Best: Raspberry PI for hardware acceleration

Install

1. Use precompiled debian package (recommended)
2. Compile manually (advanced)

Configure

1. Configure resolution, brightness or image quality
2. See different streaming options
3. See example configurations

Advanced

This section contains some advanced explanations that are not complete and might be outdated:

1. High-performance mode via ISP for CSI
2. High-performance mode via direct decoding for USB
3. High-compatibility via libcamera on Raspberry PI
4. Performance analysis
