The PyAV library does not install properly for version 7.0.1

[necronomican]

Overview

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

Expected behavior

It was expected that the package will install after ffmpeg version > 4 was installed.

Actual behavior

The build/install fails with the following error

  ERROR: Failed building wheel for av

Investigation

I tried to compile download the av package and compile it using setup.py and the --ffmpeg-dir flag pointing to the ffmpeg directory. Installation fails.

Reproduction

Have not tried on any other system.

Research

I have done the following:

• Checked the PyAV documentation
• Searched on Google
• Searched on Stack Overflow
• Looked through old GitHub issues
• Asked on PyAV Gitter
• ... and waited 72 hours for a response.

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.

[mikeboers]

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?

[necronomican]

Yes there was a ffmpeg 3.x but uninstalled it and installed 4.1.3. I uninstalled it and installed the latest ffmpeg

[mikeboers]

Okay. Thanks. I'm gonna go make a note in #605

[necronomican]

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.

[necronomican]

Oh and thank you for the prompt response mate!

[RobertSwirsky]

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

Building ffmpeg with the flag --enable-shared
Check ffmpeg is running, maybe the lib path is missing (add /usr/local/lib to LD_LIBRARY_PATH)
Clone PyAV
Comment out line 95 in setup.py
source scripts/activate.sh
make

with little success. Now I'm getting errors like this when linking against the shared ffpmeg libraries that got built:

/bin/ld: /usr/local/lib/libswscale.a(rgb_2_rgb.o): relocation R_X86_64_32 against `.rodata' can not be used when making
a shared object; recompile with -fPIC
/bin/ld: /usr/local/lib/libswscale.a(scale.o): relocation R_X86_64_32 against `.rodata' can not be used when making a sh

/bin/ld: /usr/local/lib/libswscale.a(hscale.o): relocation R_X86_64_32S against `.text' can not be used when making a sh
ared object; recompile with -fPIC
/bin/ld: final link failed: Nonrepresentable section on output

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!

[jlaine]

You are linking against a static FFmpeg (see: libswscale.a, not libswscale.so.X) which is not supported as stated in #510

[jlaine]

As of PyAV 8.0.0, binary wheels are provided which will greatly simplify installation and should solve your issue.

[youben11]

@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

[thmiller]

@youben11 try installing the latest pip. Ubuntu's packaged version of pip (9.0.1) is too old for anything labeled manylinux2010 or later.

https://pip.pypa.io/en/stable/installing/

[genekogan]

I am also having this issue on the latest pip3 with the binary for PyAV 8.0.2. Trying to install av on Jetson Nano (aarch64).

I gather it may be connected to where ffmpeg is installed (I just used sudo apt get ffmpeg).

python3 -m pip install av
