## v1.5.0
- New: set encoder for video recordings with `cameraVideoCodec` ([#174][174])
- New: set max duration for videos with `cameraVideoMaxDuration` ([#172][172])
- Enhancement: reduced lag with continuous gestures (ev, zoom) ([#170][170])
- Bug: tap to focus was crashing on some devices ([#167][167])
- Bug: capturePicture was breaking if followed by another event soon after ([#173][173])
https://github.com/natario1/CameraView/compare/v1.4.2...v1.5.0
### v1.4.2
- Add prefix to XML resources so they don't collide, thanks to [@RocketRider][RocketRider] ([#162][162])
- Add `videoMaxSize` API and XML attribute, to set max size video in bytes, thanks to [@chaitanyaraghav][chaitanyaraghav] ([#104][104])
- Improved the preview size selection, thanks to [@YeungKC][YeungKC] ([#133][133])
- Improved the playSounds attribute, was playing incorrectly, thanks to [@xp-vit][xp-vit] ([#143][143])
https://github.com/natario1/CameraView/compare/v1.4.1...v1.4.2
### v1.4.1 ### v1.4.1
- Fixed a bug that would flip the front camera preview on some devices ([#112][112]) - Fixed a bug that would flip the front camera preview on some devices ([#112][112])
