Aarch64 wheel is missing on PyPi

[odidev]

I have seen that the aarch64 wheel is missing in Pypi. It will be useful if the aarch64 wheel is released as -

• The Arm architecture has been available on AWS (Graviton2) for about 2 years now and has seen a lot of adoption by various organizations. The install base of Arm users is growing at a rapid pace.

• Oracle cloud will be releasing Arm based Compute Shapes in the future. Please see

• Generally, there is a lot of momentum behind various products switching to Arm based CPUs. For example, the Microsoft surface Pro X is an Arm based device.

@almarklein Please let me know your interest in releasing aarch64 wheels. I can help in this. To start with can you please suggest the steps you are using for building the wheel.

The process, which could improvements on many fronts:

• We download the prebuild ffmpeg-exe binaries here.
• We then use this code to wrap these up in platform-specific wheels. This can be done on any platform, except Windows because of a chmod issue.
• Some definitions are here: https://github.com/imageio/imageio-ffmpeg/blob/master/imageio_ffmpeg/_definitions.py

So if there is a prebuild ffmpeg exe for aarch64, the process should be relatively straightforward.

Otherwise, do you think a CD workflow on Github actions could help here?

Arm64 binary is available in the form of tar here

I have followed the following steps to create and test the wheel for aarch64 in quay.io/pypa/manylinux2014_aarch64 docker-

• Downloaded and untared the ffmpeg-4.2.2-arm64 tar file.

• Cloned imageio-binaries and imageio-ffmpeg package. Also install invoke using pip.

• Renamed the binary to ffmpeg-linuxaarch64-v4.2.2 and placed inside imageio-binaries/ffmpeg/ folder.

• Did the following modification in file to create a wheel for aarch64.

Commit Link - https://github.com/odidev/imageio-ffmpeg/commit/e43f6e175393e689a745c485a5e629c553e13bc3

• Ran the /opt/python/cp36-cp36m/bin/python -m invoke build command in order to build the wheel for aarch64.

• Installed the created wheel and some dependencies like psutil, pytest-cov, pytest which are used for testing.

• Place the binary to imageio-ffmpeg/imageio_ffmpeg/binaries/ folder and add execute permission.

• Then ran /opt/python/cp36-cp36m/bin/python -m invoke test command to test the wheel.

Could you please suggest further blockers in releasing the wheel for aarch64?

[almarklein]

Thanks for looking into this! In that case I don't think there are any blockers. We should add the new ffmpeg binary to imageio-binaries, and add the changes in the commit that you referenced. Could you please make a PR for these?

[odidev]

I have raised the PR here and also raised the PR for the binary in imageio-binaries

[almarklein]

Thanks! I just pushed a new release to pypi, so if all is well, you should be able to pip install imageio-ffmpeg on aarrch64.
