Enable logging from the command line

 From a command prompt in your Flash Media Live Encoder installation directory, start Flash Media Live Encoder using the /l parameter in the following format:

FMLEcmd /l [path\]log_file

Here path (optional) and log_file are the path and filename of the log file you want to create. If path is not specified, the log file is saved in your My Documents\My Videos folder.

For example:

FMLEcmd /p c:\Profiles\my_profile.xml /l c:\Logs\my_log.txt
