Yes, thanks to the open source H.264 codec from Cisco. This is about open source options and I think Firefox's decisions are completely valid.

The way that article is written makes it sound like a closed-source codec, but it is actually open:

https://github.com/cisco/openh264

and the code is better than I expected from a commercial project, it even uses may_alias properly. I wonder why the decoder doesn't support CPU multithreading, though? Slice threads are pretty simple to add.

It's about the patents.

"while OpenH264 is not truly open, at least it is the most open widely used video codec"

Well Web rtc in firefox uses the "H.264 codec from Cisco".

Normal videos like youtube uses the operating system decoder.
