怎么优化摄像头启动慢 #32

Closed sliontc closed 4 months ago

sliontc commented 1 year ago

每次打开摄像头都很慢，要好几秒，怎么优化

jenly1314 commented 1 year ago

你这说的与实际的相差太远，建议看下日志。README 中有GIF展示的效果图，启动时会有短暂的黑屏过程（不到一秒）。

这是日志，能帮忙看看吗？

根据你发的日志信息：大概意思是你这个设备的摄像头配置信息与实际的硬件对不上，在读取可用摄像头的配置时，存在ID为0的摄像头，但是进行校验的时候，lensFacing 为空了，所以导致根据配置去尝试打开ID为0的摄像头时，找不到可用的摄像头；然后使用传统的方式去尝试强行打开的摄像头，即：Using legacy camera HAL。

我很好奇，你测试的这个设备是手机吗？

不是手机，是一个定制平板。 401683901183_ pic
