在全志r40m平台调通ov5640（分色排版）V1.1版本
来源：互联网 发布：泼墨门事件知乎 编辑：程序博客网 时间：2024/04/30 02:23
OV5640的驱动里面经过搜索分辨率可以设置为：2592x1936, 2048x1536, 1600x1200, 1280x960, 1024x768, 1920x1080 ,1280x720, 800x600, 640x480
拍照出来的分辨率有：2592x1936, 2048x1536, 1600x1200, 1920x1080 ,1280x720,
丢失的分辨率有：1280x960, 1024x768, 800x600, 640x480
可能与全志R40平台的Android的framework有关系。或者是驱动里面有些分辨率没有进去？
在全志r40m平台调通ov5640
2017/11/20 9:18
版本：V1.1
开发板使用：BPI-M2U
1、配置ov5640在android层配置的分辨率（预览/拍照/录像）
注意：系统自带的快拍APP就在这里查找分辨率参数发送到camera的HAL层。
这里的默认分辨率设置为：640x480
驱动里面搜索可以设置为：2592x1936, 2048x1536, 1600x1200, 1280x960, 1024x768, 1920x1080 ,1280x720, 800x600, 640x480

- maxPrefetchYUVFrames: maximum prefetch YUV frames for encoder,

出图的效果：红绿蓝都正确出来了，拍照的颜色在电脑上面正常。但是（默认的驱动下）通过HDMI输出颜色偏暖色，不知道是HDMI输出的问题，还是显示的问题。
OV5640的驱动里面经过搜索分辨率可以设置为：2592x1936, 2048x1536, 1600x1200, 1280x960, 1024x768, 1920x1080 ,1280x720, 800x600, 640x480
拍照出来的分辨率有：2592x1936, 2048x1536, 1600x1200, 1920x1080 ,1280x720,
丢失的分辨率有：1280x960, 1024x768, 800x600, 640x480
可能与全志R40平台的Android的framework有关系。或者是驱动里面有些分辨率没有进去？
以1080p的分辨率录像可以达到30fps。（通过射手播放器显示：）
视频: MPEG4 Video (H264) 1920x1080 29.98fps [VideoHandle]
音频: AAC 44100Hz 单声道 96Kbps [SoundHandle]
视频画面： 1920 x 1080 (画面比例 16:9)
时间长度： 00:54:36
文件尺寸： 1192MB (1250540926 bytes)
文件类型： stormplayer.mp4
如果采用核心板设计，摄像头在底板上，通过FFC排线/插针连接，CB-S开发板以1080p录像只能够到25fps。
也就是FFC排线/插针传输的可靠速度（每秒）：
1920*1080*2*25B=103680000B=829440000b（不到1Gbps）
速算:
1920*1080*2*25B约等于2000*1000*2*25B=2M*50B=100MB约等于1Gb（速算的时候1B取10位）
1080p录像的体积：
录像一分钟不到25MB。也就是一秒钟不到0.5MB。
一小时不到1.5GB（参考：54分钟使用了1.22GB）
