NAME¶
Media::Convert::Asset::PNGGen - Generate a video from a (list of) PNG files
SYNOPSIS¶
use Media::Convert::Asset; use Media::Convert::Asset::PNGGen; use Media::Convert::Pipe; my $input = Media::Convert::Asset::PNGGen->new(url => $input_png_filename); my $output = Media::Convert::Asset->new(url => $output_filename); Media::Convert::Pipe->new(inputs => [$input], output => $output)->run;
DESCRIPTION¶
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.
BUGS¶
This module does not work correctly with Media::Convert::Map. If you need to create a map, first generate a video with this file and then initialize a regular Media::Convert::Asset object with it.
