Good article on H.264 patent licensing costs that should put to rest any lingering concerns: http://bit.ly/bdpzDk
Essentially: stop worrying about it and continue being creative.
The biggest fear Iâ€™ve heard expressed from opponents of the H.264 standard and advocates of competing standards is cost. But are those fears justified? Iâ€™ve taken a closer look at the legal and technical documents involved, and Iâ€™m convinced that those fears are vastly overblown. As I explain below, the cost per user is literally pennies, and thereâ€™s already a cap in place that guarantees the rates wonâ€™t rise more than 10% in the future. (As a side note, I completely understand and sympathize with the objections that some people have to software patents in general. But here in the real world, those patents exist and are routinely enforced in courts, at great cost to the participants.)
