README
Present sample Application is built for the [Google Coral Dev Board](https://coral.ai/products/dev-board/)
This repository provides an example that sets up the TPU accelerator, so that it can be used from within a container running on balenaOS on the Google Coral Dev Board.
The `Dockerfile` contains comments regarding the installation of various packages that are needed to run the sample python application provided by Google.
Actual output observed when running the Google image classification python sample in this APP:
> 19.12.19 10:37:06 (+0200) main Running sample: /usr/share/edgetpu/examples/classify_image.py
> 19.12.19 10:37:07 (+0200) main ---------------------------
> 19.12.19 10:37:07 (+0200) main Ara macao (Scarlet Macaw)
> 19.12.19 10:37:07 (+0200) main Score : 0.613281
This application was built based on the mendel-day distribution, using documentation available at: https://coral.ai/examples/classify-image/
For GStreamer use-cases, the imx packages can be set-up by uncommenting the all the packages that are commented in the Dockerfile, for example:
> RUN apt-get update && apt-get install gstreamer1.0-plugins-base=1.12.2+imx-2 libgstreamer1.0-0=1.12.2+imx-2 libgstreamer-plugins-base1.0-0=1.12.2+imx-2 imx-gst1.0-plugin=4.3.4-4 gstreamer1.0-plugins-good=1.12.2+imx-4 gstreamer1.0-plugins-base-apps=1.12.2+imx-2 gstreamer1.0-tools=1.12.2+imx-2 gstreamer1.0-plugins-bad=1.12.2+imx-5 gstreamer1.0-pulseaudio=1.12.2+imx-4 libdrm-vivante=2.4.84+imx-mendel2 libdrm-libkms=2.4.84+imx-mendel2 wayland-protocols=1.13+imx-2 libgstreamer-plugins-bad1.0-0=1.12.2+imx-5 ...
NOTE: The above packages are commented out and not installed by default in the Dockerfile as this will lead to an increase of the overall image size.
It is recommended to always install only the packages that are going to be used in the target application.
In order to check gstreamer installation:
> gst-inspect-1.0 | grep vpu
> vpu.imx: vpudec: VPU-based video decoder
Sample GStreamer Video playback:
> export XDG_RUNTIME_DIR=/tmp/
> gst-launch-1.0 playbin uri=file:///usr/src/app/MyMP4VideoFile.mp4 video-sink=waylandsink
Gstreamer debug logs during playback:

To run the project-posenet from the coral github repository, it's necessary to export XDG_RUNTIME_DIR=/tmp/ before running the video examples.
NOTE: Video output using this sample APP is available for the Google Coral-Dev starting with BalenaOS 2.46
