Basic conversion

Copy your extension to [web/]typo3conf/ext/ of your composer mode TYPO3 (or kickstart one with extension_builder).
Add autoload entry to your root composer.json (that one which requires "typo3/cms")

"autoload": {
	"psr-4": {
		"T3easy\\MyExt\\": "web/typo3conf/ext/my_ext/Classes/"
	}
}

Run composer dump-autoload -a to update the autoloader.

1. Copy m3u8 link

2. Run command

echo "Enter m3u8 link:";read link;echo "Enter output filename:";read filename;ffmpeg -i "$link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 $filename.mp4

The aim of this gist is to fix the following informative post about uploading via XHR.

Fixing the HTML

The first part is the HTML. First of all, you really don't need JavaScript to upload a file but you do need a proper form. Secondly, inputs in a form shouild have a name, because the name is what the server will receive: not IDs, names!

Command basics

To connect to MSSQL using PHP 5.6 we'll need to use PDO's DBLIB (PDO_DBLIB) http://php.net/manual/en/ref.pdo-dblib.php and FreeTDS http://www.freetds.org/

This quick tutorial is using Ubuntu Server 14.04

First, make sure you're up to date on all of your packages.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

I'm using PHP 5.6.9 (https://launchpad.net/~ondrej/+archive/ubuntu/php5-5.6)

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus
