I use usb camera to captrue video on TX2 Developer Kit.
In tegra_multimedia_api/samples:
if I only run 12_camera_v4l2_cuda this sample code,not have problem .
but if I run 12_camera_v4l2_cuda and 01_video_encode at the same time.when move objects in video or move usb camera , the video will be a strange problem, it have Random cross lines.

I doubt my code , usb camera and system too.
but after i use jetpack flash A new system, Try to replace usb camera and use Official tegra_multimedia_api samples code …I collapsed ,this problem Still exist.
I have many TX2 Developer Kit,some have this problem,some not.I even doubted whether it was related to the production batch.
I hope nvidia Official could help me to solve this problem.Anyone who has the same problem, thank you for helping me.
