Every time you execute a pipe you create a child process. This is expensive and consumes huge amounts of resource.

You can get past this by doing things like creating co-processes, or setting up cooperating processes. Again we need to see the "seven" pipes to sed. Which is very likely the bottleneck - but that is a guess.

NAME
build-lives-rfx-plugin - builds rendered effects for LiVES SYNOPSIS
build-lives-rfx-plugin script_name [plugin_dir] -get section file DESCRIPTION
This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin- multi for a script which has a language code representing LiVES-perl. The script_name must be the full (absolute) path to the plugin script, and plugin_dir can be used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not defined then /tmp is assumed. The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally by LiVES. Return values The script returns the following values 0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script was invalid 5 - the <define> section was missing from the plugin script SEE ALSO
