QB64-PE v3.14.1 is now released

[Kernelpanic]

mp4 is not an open format. It is covered by various patents. flv is a Flash Video container format. But we do not support video formats yet.

Probably we can re-visit MP4 when the patents expire.

Thanks for the tip. Do you have any more detailed information about the license fees for MP4?

I searched the internet for information about license fees for the MPEG-4 (MP4) format, and in my opinion, non-commercial use is free, especially since the Fraunhofer Institute for Telecommunications was involved in the development. Non-commercial applies to the QB64 project. The use of MP4 would made available only.

I found the following License fees:
In order to be able to use and distribute H.264, browser and operating system providers, hardware manufacturers and anyone who charges money for content on the web already have to pay license fees. For operators of non-commercial websites, the MPEG Licensing Association, which represents 26 companies with over 1000 patents relating to H.264, extended the rights to free use until 2015 in February last year. In August, the rights administrator then promised not to charge any fees for private use after that.

This also assumes commercial use:
How do you calculate the license fee?
License fee = payment to licensor/product sales price. The following applies: ROS = license fee on the sales price. LSEP = licensor's share of the company's profits.

And what about the open source implementation of the H.264 (MPEG-4 AVC) codec?
