h.264 MVC 3D support in x264/ffmpeg

Question

Many threads say that there is no open source support for h.264 3D on x264 and the technology is dead. However, I am working on x264 and would like to ask the experts here about their opinion:

• Is h.264 MVC 3D support added to any opensource codecs like ffmpeg/x264?
• If it's not currently supported in x264, could I add 3D support to x264?
• Can I take x264 source code and make changes according to the JM of H.264?
• Is there any open source 3D decoder available?

NOTE: Please don't mark this question as duplicate, as all the answers I found were answered in 2010-2012 and hoping many things have been changed by now.

Answer 1

At the moment, This is not possible. There are a number of unfinished patches for 3D-MVC encoding.

You could try using x264 with Avisynth to do the same task as this author here has done.

If you're on Windows, your second best bet (and also the easiest to use) would be BDtoAVCHD, which can do the same when authoring BD-25/50 and AVCHD structures, or ripping similar content with the MVC being preserved.

There are also notes on x264 licensing (see here) encompassing special needs such as MVC and 10-bit encoding.
