关于树莓派2 使用摄像头

Edwardwx

大家用树莓派2的有没有发现有些树莓派1的程序跑不了了。比如最基本的V4l2的demo就报错，说ioctl()有问题
有遇到类似问题的么

路过帮顶。

有作sudo apt-get update 一下嗎?
記得在官網看過說一些在树莓派1的程式要到树莓派2上跑時要先作一下sudo apt-get update
網址沒記下，google一下找找看
之前有碰過類似的問題，作一下update後就可以用了

还是不行啊，而且连mjpg-streamer编译都报错，说recipe for target 'input_testpicture.so' failed

问题更新:mjpg编译报错可能是windows解压的问题，我把压缩包拷到树莓派里再解压就能编译通过了，但还是不能正常使用，报错如下：

在我树莓派1B+上是可以正常使用的

另：我写的其他使用摄像头的程序现在可以正常使用的
