Jetson nx video vodec sdk ffmpeg compile run [h264 @ 0x55ab4840d0] Cannot load libnvcuvid.so.1 [h264 @ 0x55ab4840d0] Failed loading nvcuvid. error

[comeon]

in jeston nx 4.6 jetson-nx-jp46-sd-card-image package ,the cuda version is 10.2, video codes sdk version is 10.0.26, use ffmpeg complie and build ,
use ffmpeg -hwaccels: only cuda not cuvid

then run , find

and look sdk doc
Stub libraries (libnvcuvid.so and libnvidia-encode.so) have been included as part of the SDK package, in order to aid development of applications on systems where the NVIDIA driver has not been installed. The sample applications in the SDK will link against these stub libraries as part of the build process. However, users need to ensure that the stub libraries are not referenced when running the sample applications. A driver compatible with this SDK needs to be installed in order for the sample applications to work correctly.
i only copy libnvcuvid.so and libnvidia-encode.so to cuda/lib floder i don’t know the .so is used ,who can help me

Hi,
Video codec SDK is specific to PC with our GPU. On Jetson platforms, the hardware acceleration is enabled through jetson_multimedia_api. Please take a look at Jetson Nano FAQ
Q: Is hardware acceleration enabled in ffmpeg?

I look at

jetson-nano-faq GitHub - jocover/jetson-ffmpeg: ffmpeg support on jetson nano
then used find

it can not use hardware decoding

Hi,
The package is from community contribution. For further questions, please contact the author for help.

You may try our package which enables hardware decoding.
