• terminate comand executing by subprocess

  24 février 2014, par user2063350

  I have a python script which listens to specific stream and records it like this :

  subprocess.call(['ffmpeg', '-y', '-i', 'udp://streamurl:streamport', '-acodec', 'copy', '-f', 'mp3', 'filename.mp3'])

  Also it checks tcp connection on port 7777 (when stream is live it connects to this port on my pc) I want to terminate subprocess command every time connection on port 7777 closes. How can I do this ?

• FFMPEG options for video streaming

  26 février 2014, par YorgZ

  I am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.

  One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.

  Thanks for the help.
