I faced this error when I run ffmpeg 4.2.2 under python 3.8 environment.
The root cause is that <code>libopen264.so</code> from python 3.8 is too new for ffmpeg 4.2.2.
I can find
<code>libopen264.so.6</code> under the <code>~/anaconda3/envs/py38/lib/</code> (py38 is my conda virtual environment), but we only need an older version <code>libopen264.so.5</code>.
To solve the problem, I just make a softlink from my existing anaconda environment (python 3.7) as follows - and it works.
<code>ln -s ~/anaconda3/lib/libopenh264.so ~/anaconda3/envs/py38/lib/libopenh264.so.5</code>

Another approach that seemed easier and worked for me on Ubuntu 16.04 and python 3.8 was just calling:
<pre><code>conda update ffmpeg
</code></pre>
from <a href="https://stackoverflow.com/a/66511660/11700877">this post</a>.

blocks|key|528115|text|我也有同样的问题，为了解决这个问题，我删除了所有安装的ffmpeg：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|528116|sudo+apt-get+remove+ffmpeg

I had the same issue, to fix it I removed all installs of ffmpeg:

<pre><code>sudo apt-get remove ffmpeg
sudo apt-get purge ffmpeg
</code></pre>

After doing this, the output was still the same, <code>which ffmpeg</code> showed me I was using the one from anaconda, so I removed that one (renamed it)

Then I could do a clean install and now it works again:

<pre><code>sudo apt-get install ffmpeg
</code></pre>

blocks|key|592192|text|我通过以下方式解决了这个问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|592193|下载来自openh264的GitHub二进制|unordered-list-item|offset|length|592194|将二进制文件复制/重命名到我的conda，例如~/anaconda3/envs/py38/lib/libopenh264.so.5，其中py38是env名称|style|CODE|592195|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/cisco/openh264/releases/tag/v2.1.1^0|0|2|K|0|0|N|16|1W|4|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@$E|U|F|V|1|W]]|A|$]]|$1|G|3|H|5|D|7|X|8|@$E|Y|F|Z|I|J]|$E|10|F|11|I|J]]|9|@]|A|$]]|$1|K|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]]]

I resolved this by:

<li>Downloading the <a href="https://github.com/cisco/openh264/releases/tag/v2.1.1" rel="nofollow noreferrer">openh264 binary from GitHub</a></li>
<li>Copying/renaming the binary to my conda env, e.g. <code>~/anaconda3/envs/py38/lib/libopenh264.so.5</code> where <code>py38</code> is the env name</li>
</ul>

blocks|key|592110|text|我复制~/anaconda3/lib/libopenh264.so，粘贴到同一个文件夹并将其重命名为libopenh264.so.5。而且它是有效的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|592111|entityMap^0|3|U|1E|G|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

I copy <code>~/anaconda3/lib/libopenh264.so</code>, paste to the same folder and rename it to <code>libopenh264.so.5</code>. And it works.

I did what Synthesis did, that is
<pre><code>sudo apt-get remove ffmpeg
sudo apt-get purge ffmpeg

However, I removed the Anaconda ffmpeg module
<pre><code>conda remove ffmpeg

The clean install then did the trick:
<pre><code>sudo apt-get install ffmpeg

I recently encountered this issue with system-installed <code>ffmpeg</code>, and pip-installed <code>ffmpeg-python</code> within a conda environment.
The work-around for me was uninstalling the system ffmpeg and installing as <a href="https://anaconda.org/conda-forge/ffmpeg" rel="nofollow noreferrer">ffmpeg as a conda package</a> within my conda environment:
<pre><code># Uninstall ffmpeg system install (assumes Ubuntu)
sudo apt-get remove ffmpeg -y
sudo apt-get purge ffmpeg -y

# Install ffmpeg in conda env
conda install -c conda-forge ffmpeg
</code></pre>

I am using ffmpeg and getting this error 

<code>
ffmpeg: error while loading shared libraries: libopenh264.so.5: cannot open shared object file: No such file or directory
</code>

I have already checked if the library exists and it does. I added it to /etc/ld.so.conf as mentioned in this <a href="https://stackoverflow.com/questions/12901706/ffmpeg-error-in-linux">previous question</a> but it doesn't work.

ffmpeg: error while loading shared libraries: libopenh264.so.5

我正在使用ffmpeg并得到这个错误。ffmpeg: error while loading shared libraries: libopenh264.so.5: cannot open shared object file: No such file or directory我已经检查了库是否存在并且确实存在。我将它添加到/etc/ld.so.conf中，就像在这个中提到的那样，但是它不起作用
