Validate HLS streams

This script checks a HLS playlist for the following:

• Whether all .ts fragments can be downloaded for all quality levels
• Whether all .ts fragments have video frames
• Whether all .ts fragments start with a keyframe

These are just the issues that we check for. There are other things that can go wrong with a HLS stream.

Note that we do not actively maintain this script. You will need to fix any issues yourself.

Setup

• Install ffmpeg
• Install wget
• Install Ruby 2+
• Clone this repo to get the script

Usage

ruby validate-hls.rb "http://host/path/playlist.m3u8"

This will download, validate and print results for each .m3u8 and .ts URL.

The URL can point to either a playlist of .ts files, or to a master playlist of multiple quality playlists.

You can also pass more than one playlist URL as multiple arguments to validate-hls.rb, in which case all URLs will be validated.

The script returns an error code if there was at least one validation error.
