Hi, Nvidia team:
I run the jetson_multimedia_api/samples/01_video_encode demo in Thor.
it report error as below:
"
Creating Encoder in blocking mode
Failed to query video capabilities: Invalid argument
libv4l2: error getting capabilities: Invalid argument
[ERROR] (NvV4l2Element.cpp:63) Could not open device ‘/dev/nvidia0’: Invalid argument
[ERROR] (NvV4l2ElementPlane.cpp:517) Output Plane:Error in VIDIOC_REQBUFS at output plane: Bad file descriptor
[ERROR] (NvV4l2ElementPlane.cpp:517) Capture Plane:Error in VIDIOC_REQBUFS at output plane: Bad file descriptor
Could not create encoder
App run failed
"
SW version is 38.2.1
What’s wrong?

Hi,
It seems like the versions of jetson_multimedia_api samples and Jetpack release do not match. Do you install the samples through SDKManger, or the command $ sudo apt install nvidia-l4t-jetson-multimedia-api?
I install sample by command " sudo apt install nvidia-l4t-jetson-multimedia-api"
Hi,
Do you install the system through SDKManager or manual steps in
https://docs.nvidia.com/jetson/archives/r38.2.1/DeveloperGuide/IN/QuickStart.html#to-flash-the-jetson-developer-kit-operating-software
If you install the system through manually steps, please ensure you have –openrm while executing apply_binaries.sh.
