USB Cameras


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
