Install with pip for py-ipfs(ipfs v.0.5.X, v.0.4.X):

sudo pip install ipfshttpclient
sudo pip3 install ipfshttpclient

Migrating from ipfs-http-client 0.4.x to 0.6.0:

git clone https://github.com/ipfs/py-ipfs-http-client.git
cd py-ipfs-http-client
pip3 install flit
flit install --pth-file

Picam with python3

"PiMotion.py" runs on the Pi, recording 30-second segments of 1080p 8 fps video as .h264 from the camera to ramdisk. For each .h264 file, it also writes a .txt file recording the amount of motion detected every 2 frames (1/4 sec).

cd picam-ipfs
sudo chmod 777 ipfs_http_client.py PiMotion.py 
python3 PiMotion.py

"proc.sh" and "batchjpeg.py" run together on the remote host, in the directory where the files are. They convert the raw .h264 files to .mp4 with MP4Box, and then use the 'avconv' program to extract the still frames with motion (marked out in the *.txt logfiles) and save them as jpegs.

Running of Integrate shell code (PiMotion.py, batchjpeg.py, and ipfs_http_client.py):

cd data/
sudo ./proc.sh

MP4Box is easily installed by 'sudo apt-get install gpac' on any Debian-based system. Note I had to compile avconv from the current github source, because the standard apt-get version does not do frame-accurate seeking, which is needed for this application.

Error solution = TabError: inconsistent use of tabs and spaces in indentation

When code shows Tab or 4 spaces error, autopep8 of pip3 has to install. and it uses Filename.py.

pip3 install --upgrade autopep8
autopep8 -i stest2.py
