Comment (by kagami):
Not fully ontopic, but I think this belongs here.
There's new app for the Quest headeset, 4XVR. It claims support for both
AVC MVC and MV-HEVC. I don't have Quest, but I've checked the apk contents
and found that it uses ffmpeg (v4.4.3 LGPL2.1+) but to my knowledge
nowhere in the app or on the website FFmpeg's license is mentioned and
source code isn't available.
Furthermore, the prefix used for compilation `--prefix=/ffmpeg_443v_mvc
/ffmpeg-arm8` and few symbols inside libavcodec binary such as `Missing
reference picture, mvc_ref_pic_ptr default`, `h->mvc_ref_pic_ptr = NULL`
make me think that the developer added support for the MVC decoding to the
FFmpeg (I've checked both current and v4.4.3 ffmpeg's source code and
haven't found similar lines). Although I'm not enitrely sure.
Shouldn't the developer upload modified source code of FFmpeg as the LGPL
license requires?
