Add binary patcher system to include additional Chrome codecs (AVC/MPEG-4/Widevine) - Twitch/YouTube Live/MP4 support about mcef HOT 11 CLOSED

I am working on a new project which supports this feature

New projects are located here under "CinemaMod" https://github.com/CinemaMod

from mcef.

I am very interested in getting codec support for my MCEF. Is there a guide or reference on how to achieve this?

There's several things to consider:

If you are new to CEF/Chromium, you should know that, by distributing a version of CEF built with proprietary codecs, you are required to have licenses for those codecs.

My new project, CinemaMod, gets around this by not distributing the CEF-with-proprietary-codecs binaries directly, but rather, I distribute the normal CEF binaries without codecs and in addition include bsdiff patch files which contain binary diffs between the 2 CEF versions: CEF-with-codecs and CEF-without-codecs. The process for me is basically:

1. Build CEF+JCEF without codecs
2. Build CEF+JCEF with codecs
3. Take a bsdiff between the 2 sets of binaries
4. Create manifest files (list of binaries + hashes) for each build (JCEF-w-codecs, JCEF-wo-codecs, the bsdiff files)
5. Upload the manifest files for each build, upload JCEF without codecs, upload the bsdiff binaries all to my S3 bucket in a structured way

(As you may notice, I have support for Windows x86_64 and Linux x86_64 at the moment. I don't have a working macOS build yet.)

I'm not sure how technical you want to get, I just thought I would describe my process for context. It would be possible to use my "downloader/patcher" system from CinemaMod in MCEF if you wanted to utilize my newer JCEF builds with codec patches. The process for that in the code is basically:

1. When MC launches, check the disk to see if we have JCEF installed in the CinemaMod libraries path
2. If not installed, download JCEF without codecs
3. Download the codec bsdiff patch files
4. Apply the patches to the JCEF build without codecs

See this package for an example of how that's all done: https://github.com/CinemaMod/CinemaMod-Fabric/tree/master/src/main/java/com/cinemamod/downloader

My new project, CinemaMod, gets around this

This is also a legally gray area for sure. I'm not a lawyer so don't take this as fact.

Thank you very much for responding! I am looking into getting this to work on my end.

It works beautifully thanks again!

I can watch a 4k movie from my Plex server in Minecraft!

Glad you got it to work. It would probably be possible to get a plex player working in CinemaMod so that you have additional features such as: multiplayer video sync, video queue/skip/vote skip, video timeline as a boss bar, regional theater boundaries defined by WorldGuard regions, and other stuff as well

I'd love to use your CinemaMod but I'm stuck on a long term build using 1.12 atm. Multiplayer video sync would be amazing!

necroing, but the links are now dead. is there a new way? I am using Mysticpasta1's MCEF fork.

Hope this may be added soon :)
In the meanwhile, .webm seem to work 👍

This issue is now irrelevant with MCEF 2.x. The binaries that are included contain the codecs
