Unable to install decord video reader on Jetson Nano

Hi,

I tried installing decord on Jetson Nano using :

pip install decord

but bumped into an error :

Target Platform is not supported yet.

Any help on either building the package on nano or pip install ?

Thanks

I don’t think making it from source will work either. Jetson uses Nvidia GStreamer API, but most applications expect libnvcuvid (Nvidia Video Codec SDK), which is not available on Jetson. That’s where my attempt to build from source ended. I don’t know how difficult it would be to port the application from libnvcuvid to GStreamer.

hi,
For multimedia usecases on Jetson platforms, we suggest use gstreamer or jetson_multimedia_api. Please refer to documents:

Welcome — Jetson Linux<br/>Developer Guide 34.1 documentation

Jetson Linux API Reference: Main Page | NVIDIA Docs

Thanks @jeremyshaw1 I tried building it from source with CUDA=OFF on Nano and the build went successful.

I have few CUDA path issues which I am trying to build it again with CUDA support ON.

Thanks @DaneLLL will look at it.

Thanks

@jeremyshaw1 This is what I am getting an error while I try to import :

import decord

Any ideas how to get around this ?

Thanks
