Google Chrome and Chromium have several differences. For example, they support different set of audio and video codecs:


Google Chrome

AAC, H.264, MP3, MP4, Opus, Theora, Vorbis, VP8, VP9, and WAV


Chromium

Opus, Theora, Vorbis, VP8, VP9, and WAV


As you may see Google Chrome supports H.264, MP3, and MP4 codecs when Chromium doesn't. The reason is that these codecs are proprietary and cannot be used in the open-source and commercial projects by default. To get the rights to use the codecs, companies must pay a royalty fee to the patent holders. Different codecs have different patent holders. For example, in order to use H.264 codec, companies must acquire the licence from MPEG-LA company. You can read more about their license terms on the MPEG-LA's website.


Enabling proprietary codecs

Patent holders don't licence codecs to the software that represent only a part of the final product deployed to the end users (e.g. libraries, such as JxBrowser). In order to support H.264, MP3, MP4 and other proprietary codecs in your products, you need to acquire an appropriate licence.


If you need to play MP3, MP4, and H.264 formats on the web pages loaded in JxBrowser, you need to perform the following actions:

  1. Contact the patent holder (e.g. MPEG-LA) and obtain licence to use the proprietary codecs you need.
  2. Contact our support team and request a custom build of JxBrowser with enabled proprietary codecs. If you are not yet a customer of JxBrowser, please write to sales@teamdev.com.

With the licence and custom JxBrowser build, you will be able to load web pages with the MP3, MP4, and H.264 formats and play audio and video files, just like in Google Chrome.

Netflix

JxBrowser does not support Widevine at the moment. Web services that use Widevine to distribute content, such as Netflix, Amazon Prime, etc., do not work in JxBrowser/Chromium.
