7.11 CGI

This example consists of 2 parts: ﬂix2_sample.cgi and process_sample.cgi. ﬂix2_sample.cgi searches for

uploaded ﬁles to encode and allows the user to select one while giving the option to set values for most

of the engine’s functions. The engine options are separated into sections that map to the engine’s include

ﬁles.

To use this example navigate to ﬂix2_sample.cgi in your web browser, select a ﬁle from the list, set any of

the desired options and click the encode button. The selected options are submitted to process_sample.cgi

which runs the encode loop.

Default ﬁle locations used by the scripts:

Input : /var/www/cgi-bin/ﬂixmedia/in ($indir in ﬂix2_sample.cgi)

Overlay : /var/www/cgi-bin/ﬂixmedia/overlay ($overlaydir in ﬂix2_sample.cgi)

Output : /var/www/cgi-bin/ﬂixmedia/out ($outdir in process_sample.cgi)
