  • 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.
