Comment (by Gary Buhrmaster <gary.buhrmaster@…>):

 Replying to [comment:12 jyavenard]:
 > Where have you found that those patents have expired? would like to see
 some proof of that

 I did say most, not all, and MPEG-2, not the others.  It was all the news
 about a year ago (when a couple of big ones expired).  Anyway, the easiest
 reference is probably the wikipedia page
 http://en.wikipedia.org/wiki/MPEG-2 (click "show" on the patents table).


 > Mozilla is even removing support for using an external, presently
 installed libavcodec/libavformat due to patent on h264 and AAC by various
 parties and instead moving to proprietary decoders from software companies
 with the appropriate license.

 Yes, H.264 and AAC have different patents/pools.  For simple values, every
 codec (that people want to use) has someone who has claimed a patent on
 it.  Sometimes two or more orgs (the LZW patent, for example)

 > Something to do with the "straight face" test of not knowingly getting
 around patent infringements.

 Depending on the jurisdiction, and exact wording of the laws, knowingly
 and/or contributory infringement can result in '''interesting''' results
 (where '''interesting''' is never cake and ice cream).  Mozilla, I am
 sure, took their action after due consideration of the potential risks as
 outlined by their Counsel.
