Dependencies:

Ubuntu: 20.04
conda: 4.12.0
Python: 3.8
Pytorch: 1.7.1
ffmpjpe: 4.2.3 (conda-forge)

I am facing a problem after installing FFmpeg from the conda-forge channel as follows command:

$ conda config --add channels conda-forge```
$ conda install ffmpeg

$ ffmpeg -version error message:

ffprobe: symbol lookup error: /home/user/anaconda3/envs/myenv/bin/../lib/./libgnutls.so.30: undefined symbol: mpn_add_1, version HOGWEED_4

I have also try

$ pip install ffmpeg

or

$ pip install ffprobe

or

$ conda install ffmpeg-python

But they do not work for me.

Could anyone point me out how to solve this issue??
Thanks in advance!!

I finally solved this problem by

Step1. Install ffmpeg on your OS {e.g. in my case, Ubuntu}

from Download FFmpeg website

for my ubuntu case, just use the following command:

$ sudo apt-get install ffmpeg

Step2. Verify the Installation

$ ffmpeg -version

ffmpeg version 4.2.7-0ubuntu0.1 Copyright (c) 2000-2022 the FFmpeg developers
built with gcc 9 (Ubuntu 9.4.0-1ubuntu1~20.04.1)

libavcodec     58. 54.100 / 58. 54.100
libavformat    58. 29.100 / 58. 29.100
libavdevice    58.  8.100 / 58.  8.100
libavfilter     7. 57.100 /  7. 57.100
libavresample   4.  0.  0 /  4.  0.  0
libswscale      5.  5.100 /  5.  5.100
libswresample   3.  5.100 /  3.  5.100
libpostproc    55.  5.100 / 55.  5.100

I can confirm that FFmpeg has been installed successfully at this time. But when I run my python script, it shows different error message like

ffmpeg: error while loading shared libraries: libx264.so.138: cannot open shared object file: No such file or directory

When I retry $ ffmpeg -version it shows this error again. (I guess it was caused by a version mismatch issue??)

So I go on the Step 3

Step3. Re-open the terminate、Uninstall and Re-install ffmpeg from following command

$ conda uninstall ffmpeg
$ conda install -c conda-forge ffmpeg

Re-try:

$ ffmpeg -version

ffmpeg version 4.2.7-0ubuntu0.1 Copyright (c) 2000-2022 the FFmpeg developers
built with gcc 9 (Ubuntu 9.4.0-1ubuntu1~20.04.1)...

Then my issue has been solved!! I can successfully run my python script now!!

For those who stumbled upon this issue as I did. I hope this response could help and work for you too.

The anaconda site suggests to try all of the below. Do you get a problem with all of the channels:
```
conda install -c conda-forge ffmpeg
conda install -c "conda-forge/label/broken" ffmpeg
conda install -c "conda-forge/label/cf201901" ffmpeg
conda install -c "conda-forge/label/cf202003" ffmpeg
conda install -c "conda-forge/label/gcc7" ffmpeg
```

This is likely due to channel mixing. If you need to use Conda Forge, then use just Conda Forge (it’s a standalone channel).
```
conda create -n foo -c conda-forge python=3 ffmpeg ...
```
While Anaconda documentation might imply that one can simply use packages from other channels, the fact is that they don’t test for such compatibility.
