Face Tracker 0.7.0

This is a experimental release.
Detection and tracking has improvement. Users may experience differences from the old version.
Face Tracker PTZ has many improvements.

Changes

• Add a new property to adjust tracking threshold
• Add a new feature to crop image for face detection (not effective for tracking)
• Changes only for PTZ
  • Fix an issue that zoom control was not working when sending through obs-ptz.
  • Stop camera before exiting OBS Studio or before removing the filter.
  • Add a new property to attenuate after lost face
  • Remove deprecated ptz devices (use obs-ptz)
  • Separate PID control parameters for each axis

Limitation

• Binaries for Windows, macOS, and Ubuntu are not tested.
• Currently the plugin works for one face. If there are two or more faces, the plugin might hover back and forth over the faces.
• Transition with `Duplicate Sources`, the tracking may start from the initial condition. Recommended to disable `Duplicated Sources` so far.
• Consumes a lot of CPU. It is recommended to have enough test beforehand to ensure it won't affect encoding.
• There is no warranty for the results. Use at your own risk.
• Deb package for Ubuntu requires OBS Studio 27 or later. Binary packages for Windows and macOS work with OBS Studio 26 or later.
• I heard some anti-virus software detect the installer. If you see your anti-virus software alarms the installer, please file to [issue page](../../issues/new) with the information of (a) anti-virus software and (b) type of the virus (either text or screen shot is ok).
  I'd like to note that all binaries are build on a Microsoft-hosted machine and the whole recipe is available on [azure-pipelines.yml](../../blob/main/azure-pipelines.yml).

This is a hotfix release with a bugfix for PTZ.

Changes from 0.4.1

• PTZ: Add supported frame formats YUYV and YUY2

Add zoom control through [obs-ptz](https://github.com/glikely/obs-ptz/)
The new zoom control requires obs-ptz v0.10.3 or later. For older version, only pan and tilt will move.

This is a new release with improvements for zoom control.

• Add attenuation property for zoom (face tracker filter only)
• Separate LPF parameter for zoom (both face tracker filter and PTZ)

Due to this change, all users will experience different behavior of the zoom control.
If exactly same behavior is needed, set `Attenuation (Z)` to `0 dB` and `Track LPF for Td (Z)` to same value as `Track LPF for Td (X, Y)`.

This is a minor release including PTZ camera control through PTZ Controls version 0.9.0.

• Face Tracker PTZ:
  • Add PTZ camera control through PTZ Controls version 0.9.0.
    • This feature is under testing. Future release of either plugin could break the functionality.
    • The zoom control is currently not implemented.
• Face Tracker:
  • No changes

This is a release with some small new features.

• face-tracker: Add hotkeys to pause/resume tracking and reset tracking states.
  • 3 hotkey settings are added; Pause, Resume, and Reset. If you assign a same key to Pause and Resume, you can toggle with that key.
  • I'd like to thank @rusty1 and @GregPeatfield for the idea.
• PTZ: Add TCP connection to VISCA device.
  • I'd like to thank @GregPeatfield and Jimcom US for providing support to debug this feature.

This is a hotfix release of Face Tracker for OBS Studio.

• Changes from 0.2.1
  • Fixed a memory access violation on Face Tracker PTZ, which was introduced at 0.2.1.
• Changes from 0.2.0
  • Fixed a bug of memory leaks. Expecting less memory usage than old versions.
  • Binary for macOS is signed and notarized. Expecting users on macOS 10.15 or later won't see security errors.

• New property to always show information. It's useful to make a demo of this plugin.
