Can not run camera_recording on Jetson tx2.

Hi,

After install Jetpack 3.1, I get the camera_recording from tegra_multimedia_api/samples/10_camera_recording.

Only the on board camera is available on my Jetson TX2.

The log is as follows:

nvidia@tegra-ubuntu:~/tegra_multimedia_api/samples/10_camera_recording$ ./camera_recording

How can i fix this issue?

By the way, when I was installing the Jetpack 3.1, some lib file failed to be installed such as libopencv4tegra, libopencv4tegra-dev, cuda-toolkit-8-0. Could this be the reason for camera_recording failed？

Thanks.

Hi yafei,
We don’t reproduce the issue. It is due to the failure:

(Argus) Error NotSupported: Failed to initialize EGLDisplay (in src/eglutils/EGLUtils.cpp, function getDefaultDisplay(), line 75)

Do you manually stop some services about EGLDisplay?

Hi DaneLLL,

The error you mentioned last time can be fixed through “export DISPLAY=:0”.

What does “export DISPLAY=:0” means?

I don’t know if this is “manually stop some service about EGLDisplay”.

Whatever, problem resolved.

Thanks.
