List of improvements:
1. Using CameraX in the attachment menu and for recording video messages when api ≥ 21, otherwise using legacy camera
2. Using max photo resolution available on device with target aspect 16:9, target video resolution increased to 1080p or max available on device
3. Fixed bug with cameraview glitch when photo attachment layout scrolls and cameraview goes off the screen, added cameraview parallax
4. Fixed mirroring video when recording with front face camera in attachments
5. Added exposure compensation feature in cameraview to expand the possibilities of shooting in contrasting light, added EV slider, zoom slider moved to a more intuitive location. Added 2D gesture recognition while recording to adjust zoom and EV at the same time
6."Use CameraX API"/"Use legacy camera API" in debug menu

Всего улучшений: 6
К сожалению, в ходе тестирования реализации CameraX были выявлены следующие недоработки, в числе которых критические:

– Приложение вылетает при последовательном нажатии на кнопку затвора (Samsung Galaxy J7 Android 9).
– Приложение вылетает при записи видео, если палец убран с кнопки записи.
– Переключение между камерами происходит с заметными рывками.
– Первое касания экрана для фокусировки после работы с кнопкой вспышки активирует вспышку.
– Смена ориентации устройства вызывает рывки в перерисовке интерфейса камеры, что особенно заметно на менее производительных устройствах.
– Cмена ориентации устройства может вызывать искажения изображения – как в миниатюре камеры, так и при её активном полноэкранном использовании (Samsung Galaxy J7 Android 9).
Samsung Galaxy S10 (Android 11); Samsung Galaxy J7 (Android 9); Nexus 5X (Android 8).

Almost on every device video recording is accompanied by a black screen appearance and sometimes results to no output file

On some older devices when CameraX is trying to bind 3 use cases for preview, image and recording simultaneously an exception occurs like "java.lang.IllegalArgumentException: No supported surface combination is found for camera device - Id : 0. May be attempting to bind too many use cases." In this case, I have to rebind it depending on what is currently being used, which causes the screen to blink (perhaps I should have provided a placeholder for this time). Judging by the video, videoCapture called onError and rebind use cases back, it strange but it should have written exception to the FileLog which might help figure out the reason.
