If I’m interpreting this correctly, many MP4 patents are going to expire next year. 🎉

What are the consequences of this particular patent expiring ?
Someone will most likely patent hack it in order to reclaim it, then try to patent troll about it… Because corporate people are jerks.
Has this happened with other codecs?
Parents for MP3 expired in 2017
The poor kid
How? If the tech is older than 25 years, it’s prior art no matter what. MP3 is fully free for the same reasons.
Happened recently with a 1995 patent by a Stratasys, on a stronger technique for 3D printing using a brick infill method.
Someone re-parented a variation to prevent it being public domain until 2040.
Thisbisnwhy we can’t have nice things…
So the variation cannot be used. That’s irrelevant for a file format. Some company could, for example, patent a more efficient encoding technique but the resulting file format is still public domain. So at worst an open source encoder would need to be slightly inefficient because it uses the traditional technique.
Okay, pay X amount of dollars to go say that in a few court cases, and hope you get a judge that understands.
That’s why it’s called Patent Trolling because it’s not official or legitimate.
Didn’t happen with MP3.
Sort of. That was more of an oversight from a half assed patent filing based on a little known 3d printing process that shouldn’t have been approved and is still up for challenge. That isn’t likely to happen with H.264. I’d go as far to say that it couldn’t happen with it.
On distros like Debian, openSUSE and Fedora, you need to enable a separate repository, if you want icky software, like proprietary drivers or patented codecs. In particular, you can’t watch MP4 videos. So, PeerTube and YouTube work, but if a webpage is hosting its own videos, or you happen to acquire a video file in some other fashion, there’s a good chance that it’s an MP4 file and you can’t look at it.
I’m hoping that when these patents expire, that it’s possible to ship the MP4 codecs directly, and then at least for me, that would currently result in not needing to deal with these separate repos.
When I first switched to Linux, I was nonplussed at why many videos didn’t work. It ended up being a positive learning experience, but it certainly would be nice if the codecs could be shipped directly, as you say.
Nice overview and conclusion right at the top. Last edited 19. Nov, so its pretty active. I’m glad its not named “Are We H.264 AVC Yet?”. :D
Cute kitty
Now for h.265…
I am once again reminded that if you format literally anything into a Wikipedia article I will read it with full trust. “hmm surely there is a valid reason for there to be a cat with coins on this article about video file patents”
Because he’s a cute money-cat. He is showing how much money he has.
Even if all High Profile patents in Europe expire next year, this means absolutely nothing for US-based companies/orgs or companies/orgs that trade in the US, which still has patents that won’t expire until 2027 according to this article. Even then, this means absolutely nothing because there is no such thing as a H.264 decoder/encoder that only supports the High Profile spec (aside from OpenH264, which already circumvents the patents for companies/orgs that want to use it, but is still lacking). x264 supports H.264 features from later specifications, and the patents for those things likely won’t expire until after 2030.
