USB Cameras

Overview

In general, OpenHD can automatically detect and use usb cameras that provide either raw uncompressed or already encoded (h264,h265,mjpeg) data. However, they often (not always) come with limitations:
  1. 1.
    Fixed encode bitrate - you cannot use new features like variable bitrate, and need to manually tune your link
  2. 2.
    Not ideal encoding parameters - your stream might have high latency, or bad error recovery
  3. 3.
    RAW - requires SW encoding, which only allows low resolutions/framerates, even on RPI 4
