According to the MPEG-LA Licensing Agreement MPEG-LA, any use of MPEG-2 technology is subject to royalties.

- Encoders are subject to a royalty of $2.50 per unit.
- Decoders are subject to a royalty of $2.50 per unit.
- Royalty-based sales of encoders and decoders are subject to different rules and $2.50 per unit.
- Also, any packaged medium (DVDs/Data Streams) is subject to licence fees according to length of recording/broadcast.

In the case of free software such as VLC media player (which uses the ffmpeg library) and in which the software is not sold, the end-user bears the royalty.
