Media:...:Concat(3pm)

✨ Media::Convert::Asset::Concat ✨

okay so bestie, welcome to Media::Convert::Asset::Concat — it's a Perl module in the user-contributed Perl docs, and it's literally just a Media::Convert::Asset that's made up of multiple assets glued together. slay. 💅

🌸 SYNOPSIS 🌸

use Media::Convert::Asset;
use Media::Convert::Asset::Concat;
use Media::Convert::Pipe;

my $file1 = Media::Convert::Asset->new(url => $input_file_1);
my $file2 = Media::Convert::Asset->new(url => $input_file_2);
my $input = Media::Convert::Asset::Concat->new(url => "/tmp/concat.txt", components => [$file1, $file2]);
my $output = Media::Convert::Asset->new(url => $output_file);

Media::Convert::Pipe->new(inputs => [$input], output => $output, vcopy => 1, acopy => 1)->run();

like look at that. so clean. so iconic. 🎀

🦋 DESCRIPTION 🦋

so the ffmpeg command has this whole thing called a concat file format, and you pick it with -f concat. what even is it? bestie it's essentially a text file with a header at the top, and then a bunch of URLs pointing at other files. that's it. that's the format. ✨

when ffmpeg gets told to read from one of these files, it starts reading from the first file, and then when the data from that first file is done-done, it moves on to the next file. one after another. no cap. 🔥

now for the real talk, and this part matters: for this to actually work well, all the files have to be the same format — and not just same-format at the level Media::Convert::Asset can detect, but beyond that. so it's probably not safe to use Media::Convert::Asset::Concat except on files that were created from the same recording. like same source, same everything. periodt. 💀

and since the files should be the same, Media::Convert::Asset::Concat just... assumes they are. 😌 which means when you ask it for info, it runs ffprobe on only the first of its components. not all of them. just the first one. iykyk.

👑 ATTRIBUTES 👑

Media::Convert::Asset::Concat supports all the attributes that Media::Convert::Asset supports, plus these extra ones below. main character energy fr fr. 🌈

🍓 components

should be an array of Media::Convert::Asset objects — these are the ones making up the contents of this asset. 🫶

and if you wanna add more components later, there's an add_component handle for that. iconic. ✨
