Overview

This module uses the lavfi (the "libavfilter input virtual device", you figure out how that matches the abbreviation) functionality in ffmpeg to convert an image file into a video.

It will automatically match the input framerate to the output framerate; this means that the framerate on the output file must be set, either through a profile or by setting it explicitly.

Attributes

audio_channels

The option to give to the "channel_layout" attribute of the "anullsrc" audio source. Defaults to "mono".

loop

If truthy, loops over the PNG files given. Useful if there is only one PNG file, but then a video length for the output file should be given. If falsy, stops after all the input files are processed.

Defaults to true.
