Cameraview Ex Versions Save

fixes https://github.com/pvasa/cameraview-ex/issues/232

Bug fixes

• Fix empty data for RGBA_8888 output type
• Fix incorrect output format for continuous frames mode

• Improve size fallback mechanism for continuous frame and single capture modes.
  • Check this and this doc for more info about the size selection mechanism
• Use requested output format instead of ImageReader::class to fetch list of supported output sizes from StreamConfigurationMap. This was a bug as when fetching this list using ImageReader class, it only returns list for ImageFormat.PRIVATE which might be different than actual output format.

• Fix incorrect cropping for non standard image size and orientation when images are pre-rotated
• Fix texture cropping for non standard preview size in landscape mode

• Fix video recording bug

New apis:

• cameraId - String id of currently opened camera device
• cameraIdsForFacing - SortedSet of string ids of camera devices for selected facing
• nextCamera() - Open next camera in sequence of sorted camera ids for current facing

Updated apis:

• start(cameraId) - Start now accepts an optional string cameraId to manually select which camera id to open. If nothing passed, first (default system) camera will be opened for selected facing
• app:facing AND cameraView.facing - Both now accepts a new facing value external in xml and Modes.Facing.FACING_EXTERNAL for in code usage. This facing open any external camera available and falls back to Modes.Facing.FACING_BACK if there is no external camera

• Fix incorrect output size for cropped images.
• Fix incorrect output format for RGBA type

• New apis:

  • continuousFrameSize (type: Size) Set preferred (not guaranteed) output frame size for continuous frames mode
  • singleCaptureSize (type: Size) Set preferred (not guaranteed) output image size for single capture mode

• Updated apis:

  • setPreviewFrameListener(..) -> setContinuousFrameListener(..)

• Decide orientation based on aspect ratio. For eg., x:y (landscape) and y:x (portrait) now generates different preview/output orientation independent of device/screen orientation.

• Improve image processing for RGBA_8888 format outputs

• Use Google's exif implementation as a part of library to avoid external dependency on support ExifInterface lib

• Support custom sized continuous frames and single captures different from aspect ratio and best/highest size

• Bug fixes

• Performance and stability improvements

• Make android.hardware.camera2 not required in manifest to avoid device limitation on play store.

• Move sampleApp to separate project
• Migrate sampleApp to AndroidX
• Setup local maven repo to build library module (legacy support packages and AndroidX are not compatible under same project)
• Bug fixes
