0.3.9 Beta Release 8

Added

  • MJPEG server example added that uses the hardware MJPEG encoder.
  • Example showing previews from two cameras in a single Qt app.
  • H264 encoder can accept a frame time interval to be put in the SPS headers.
  • H264 encoder should now advertise the correct level in streams for higher bitrates.
  • Exif DateTime and DateTimeOriginal tags are now added.
  • H264 encoder now supports a constant quality parameter.

Changed

  • JpegEncoder chooses pixel format automatically from the stream format.
  • Work around OpenGL import error on 64-bit OS Lite images.
  • FFmpeg: use the audio_samplerate parameter correctly.
  • camera_controls are converted to native Python types (tuples, not libcamera.Rectangle objects).
  • Camera configuration will fail if an encoder is still running.
  • Encoder interface tidied to make it easier to run a second encode "by hand" (example included).
  • Picamera2 updated for the latest libcamera which changes colour space handling.
  • Encoder outputs no longer close files that they didn't open.
  • CircularOutput class now flushes the fifo correctly when outputs are closed.
