0.3.20 Beta Release 19

Added

  • Initial support for Hailo AI devices, including some examples.
  • IMX708 helper class so that the sensor HDR mode can be set with Python.

0.3.19 Beta Release 18

Added

  • Add an example showing how to forward images to other processes using zero-copy.
  • Add a context manager method for capturing requests, e.g. with picam2.captured_request() as r:
  • Encoders can skip frames, e.g. run at half the rate of the camera.

Changed

  • Configuration alignment fixed on Pi 5.
  • Improve support for displays without alpha blending.

  • MJPEG server example with 90/270 degree rotation.

Changed

  • File descriptor leak fixed when closing DmaAllocator.
  • EGL memory leak fied.

0.3.17 Beta Release 16

Added

  • Pi 5 users can now request 48-bit RGB outputs (where each R, G and B sample is 16-bit).
  • Support for h.264 codec profiles.
  • DNG files can be written to ioBytes objects.
  • Persistent allocators added.
  • Timeout support waiting for asynchronous requests to complete.

Changed

  • FFmpeg thread queue size increased, to suppress warnings and improve behaviour.

0.3.14 Beta Release 13

Added

Changed

  • All picamera2.allocators package.

0.3.13 Beta Release 12

Added

  • Pi 5 support added. Includes platform detection, new raw formats etc.
  • Libav encoders added. These will be used as the H264 and MJPEG encoder on Pi 5.

Changed

  • Frame buffers are now cached to improve performance.
  • Encoders should no longer drop frames when closed.
  • FfmpegOutput should stop properly when there's an audio stream.
  • Updates for the latest version of libcamera, including sensor configuration.

0.3.11 Beta Release 10

Added

Changed

  • The search path for tuning files (after the libcamera re-organisation) has been fixed.
  • The built-in configuration objects (picamera2.preview_configuration etc.) are updated to work better with raw streams now that the latest libcamera is more efficient when we use them.

0.3.10 Beta Release 9

Added

  • Support for running multiple encoders, either on the same or different streams.
  • Pathlib objects now supported.

Changed

  • The camera can be stopped more quickly.
  • Fix problem passing modes from the sensor mode list to the configure methods.
  • H264 encoder quality was having no effect on bitrate - fixed.
  • ffmpegoutput - wait correctly for it to finish when we stop it.
  • Amount of CMA memory required is reduced for many use cases.

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.
  • Bug fix when capturing several DNG files back to back.
