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.
