# Changelog

## 1.2.0

### Features
- Added hardware encoder support for multiple pixel formats on ESP32-P4(>=3.0.0):
  - BGR888 (24-bit RGB format)
  - BGR565_BE (16-bit RGB Big-Endian format)
  - VUY (YUV 4:4:4 format)
  - UYVY (YUV 4:2:2 format)
- Added hardware version detection macro `ESP_H264_HW_IS_SUPPORTED_PIC_TYPE`
- Added `ESP_H264_GET_BPP_BY_PIC_TYPE` macro to determine the number of bits per pixel for a given picture type
- Added support for ESP32P4 V3 hardware versions

### Fixes
