I am using ffmpeg and getting this error
ffmpeg: error while loading shared libraries: libopenh264.so.5: cannot open shared object file: No such file or directory
I have already checked if the library exists and it does. I added it to /etc/ld.so.conf as mentioned in this previous question but it doesn't work.
Another approach that seemed easier and worked for me on Ubuntu 16.04 and python 3.8 was just calling:
conda update ffmpeg
from this post.
I faced this error when I run ffmpeg 4.2.2 under python 3.8 environment.
The root cause is that libopen264.so from python 3.8 is too new for ffmpeg 4.2.2.
I can find
libopen264.so.6 under the ~/anaconda3/envs/py38/lib/ (py38 is my conda virtual environment), but we only need an older version libopen264.so.5.
To solve the problem, I just make a softlink from my existing anaconda environment (python 3.7) as follows - and it works.
ln -s ~/anaconda3/lib/libopenh264.so ~/anaconda3/envs/py38/lib/libopenh264.so.5
I resolved this by:
~/anaconda3/envs/py38/lib/libopenh264.so.5 where py38 is the env nameI had the same issue, to fix it I removed all installs of ffmpeg:
sudo apt-get remove ffmpeg
sudo apt-get purge ffmpeg
After doing this, the output was still the same, which ffmpeg 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:
sudo apt-get install ffmpeg
I copy ~/anaconda3/lib/libopenh264.so, paste to the same folder and rename it to libopenh264.so.5. And it works.
I did what Synthesis did, that is
sudo apt-get remove ffmpeg
sudo apt-get purge ffmpeg
However, I removed the Anaconda ffmpeg module
conda remove ffmpeg
The clean install then did the trick:
sudo apt-get install ffmpeg
