I have followed the instruction of the INSTALL.md, and have installed all required library. But when I built pyslowfast, I met this error as follow:

But I have installed 'av' by conda install av -c conda-forge.Could you please give some advices?

Hi Did you solve it? I met the same issue when trying to install pyav (version 7.0.1). I have tried different ffmpeg versions (version 4.2.2, 4.1.5 and 4.0.5) but no one works.

For me the following combination works:

I guess you missed activating the conda environment . MAy be try doing the dollowing:

  1. conda activate 2.python setup.py build develop

As of version 8.0.0 (released yesterday) PyAV comes in the form of binary wheels which greatly simplifies installation. You no longer need the FFmpeg libraries and can just install it using:

pip install av
