Hi,
It only accepts UYVY in nvv4l2camerasrc. For launching source with YUYV(YUY2) format, you would need to customize the plugin. It it open source in
https://developer.nvidia.com/embedded/linux-tegra
L4T Driver Package (BSP) Sources

Please download it and take a look. The implementation is based on jetson_multiemdia_api. For YUYV, please apply the patch:
