Codec

Values in this filter define a whitelist of the codecs and formats you want to EXCLUDE in the modifed manifest, with the key denoting the content type you are targetting.

By default, the audio, video, and caption keys will accept codecs as their value. but this is not the only way to use them. You can nest other filters to target video, audio, and caption media types.
