20241220在荣品开发板PRO-RK3566的buildroot下适配gc2093
2024/12/20 16:00

@余顺?PRO-RK3566开发板挂 gc2093模块。刷 buildroot的预编译固件。
update-pro-rk3566-buildroot-hdmi-20231130-034633.img

1、现在发现 qcamera的拍照Capture、Record录像模式都是640x480分辨率。
请问可以配置成为1920x1080分辨率吗？

2、习惯了ubuntu下的ll命令了。不想输入ls -l
请问 buildroot下如何配置ll命令？

3、请问 buildroot下有什么好的的截屏指令？
Android下有 screencap

@造诣==灶燚 1, 改源码，代码默认预览640x480
2. alias ll='ls -alF'
3. weston-screenshooter

@余顺?@小灏星?请提供一下 gc2093的datasheet
请问gc2093在1080p分辨率下只有15fps吗？

1、weston-screenshooter 的 DEBUG模式？
2、gc2093在1080p分辨率下的最大帧率是多少?现在在buildroot下只有15fps
