H.264 is aimed at helping customers use applications on the internet that require video.
Firefox’s open source technology may be compromised if it chooses to use the codec as H.264 requires royalty payments.
Andreas Gal, chief technology officer at Mozilla said on the website’s blog post: “Unfortunately, no royalty-free codec has managed to get enough adoption to become a serious competitor to H.264."
The H.264 codec remains incompatible with Firefox’s open-source licence, but Cisco has provided an OpenH264 codec, which pays the licensing fees.
Firefox had previously supported Google’s royalty-free alternative, the VP8 video codec.
According to Gal, OpenH264 is a “significant victory for the open web.”
