• FFmpeg error loading shared libraries libx265.so.113

  19 février 2019, par SenDjasni

  I recently installed libx265, I dont know what happened, but when I execute ffmpeg command I got this error :

   ffmpeg: error while loading shared libraries: libx265.so.113: cannot open shared object file: No such file or directory

  I google it but got nothing specific about it.

  I also executed this command : ldd $(which ffmpeg) and got the following output :

• Missing ffmpeg in deployed application

  30 décembre 2017, par Dexstrum

  I have created a python GUI which utilizes ffmpy and tkinter. It works fine running in PyCharm and also in py2app’s alias mode. After I deployed it using py2app and ran the program, it loaded up, but nothing happened. After doing some digging, I found that the error was ’ffmpeg executable is missing.’

  I tried using pyinstaller to remedy the issue, but the application did not even run.

  The warning.txt output file gave me this :

  I am not sure where to go from here. I don’t know how to include ffmpeg into the deployed application, and when I include the modules in the setup.py file it throws me a different error. Is there a reason why the py2app is not deploying the application with ffmpeg ?

• Error when initializing webcam with ffmpeg

  I am trying to set up a webcam and stream to localhost, using ffmpeg.

  Here is a command I put into a terminal :

  ffmpeg -f alsa -ac 2 -i hw:1,0 -f v4l2 -s 1280x720 -r 10 -i /dev/video1 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -r 25 -g 20 -b:v 2500k -codec:a libmp3lame -ar 44100 -threads 6 -b:a 11025 -bufsize 512k -f flv rtmp://localhost:80/
