USB Camera

大家好，

我目前使用imx6solo芯片，linux版本为L4.1.15，使用yocto编译的BSP版本为fsl-yocto-L4.1.14_2.0.0-ga。目前有个USB摄像头需求。

1.考虑到imx6solo带有VPU视频编解码，请问这个要怎么才能用起VPU呢？

2.我们USB摄像头目前仅支持两种格式：MJPEG和YUV422。对于imx6solo的VPU可以对我们目前的两种格式进行解码吗？

另外，有建议使用gstreamer显示usb摄像头，请问要如何实现呢？谢谢

About your above questions, the default BSP support the VPU encoding, you can directly use. The i.mx6solo support encording H264, MPEG4, MJPEG, but when go to the vpu, only support the YUV420. Yes, as you said, you can use the gstreamer.
