This looks like PyAV is building against FFmpeg 3.x. You have an FFmpeg 4.1.3 from anaconda. Is there an FFmpeg 3.x from the OS as well? |
|
Yes there was a ffmpeg 3.x but uninstalled it and installed 4.1.3. I uninstalled it and installed the latest ffmpeg still fails with the same error while installing |

Okay. Thanks. I'm gonna go make a note in #605 |
|
Alright. Thanks. I will try to do something to resolve this on my system. Will share it here if it's somehow a fault on my end. |
|
Oh and thank you for the prompt response mate! |

I've been trying to install aiortc==0.9.27 for the past several days here with little luck. aiortc has a dependency on PyAV. For some reason there's no "official" repo that has a built ffmpeg for centos 7 so I had to build one by hand. I tried these instructions from #510 with little success. Now I'm getting errors like this when linking against the shared ffpmeg libraries that got built: Not sure what next step should be. I'm going to try forcing in that -fPIC option but I think I'm down a rathole! |

You are linking against a static FFmpeg (see: |
|
As of PyAV 8.0.0, binary wheels are provided which will greatly simplify installation and should solve your issue. |
|
@jlaine the binary wheels are unfortunately note compatible with all linux distribution (needs manylinux2014 and manylinux1 maybe?). I'm running ubuntu 18.04 with python 3.7 and I can't install it |
|
@youben11 try installing the latest pip. Ubuntu's packaged version of pip (9.0.1) is too old for anything labeled manylinux2010 or later. |

I am also having this issue on the latest pip3 with the binary for PyAV 8.0.2. Trying to install I gather it may be connected to where ffmpeg is installed (I just used |
|
same issue as @genekogan. Were you able to solve @genekogan ? |
|
@tushar-semwal I ended up installing it from source and that worked for me. |
|
Same issue as @genekogan & @tushar-semwal I've solved the issue by installing ffmpeg version 1. install from pip:python3 -m pip install Cython numpy Pillow2. install from apt package manager:sudo apt install yasm libvpx. libx264. cmake libavdevice-dev libavfilter-dev libopus-dev libvpx-dev pkg-config libsrtp2-dev libpython3-dev python3-numpy3. download & install

Thanks! |
Did not work for me, unfortunately. Looked good anyway... |

Overview
While installing the PyAV package via. PYPI (pip install av), the build breaks. And it does not install.

I have done the following:
Additional context
I want to use "aiortc", this is a dependency. I have read an issue on PyAV repo. in which it was said "it is broken since 7.0.0". Tried installing 6.2.0 with success. But 7.0.1 is what is needed.
