vaapih264enc and x264enc usage for encoding MVC / stereo?

[Víctor M. Jáquez L.]

Hi,

First thing to check is does your hardware support MVC?

You can know that by running `vainfo`

And you should see

      VAProfileH264MultiviewHigh      : VAEntrypointEncSlice
      VAProfileH264StereoHigh         : VAEntrypointEncSlice


Second thing is that setting the profile via capsfilters is not supported yet
by the vaapi encoders: https://bugzilla.gnome.org/show_bug.cgi?id=757941

Finally, I haven't tested MVC encoding personally, but grepping the source
code the way how MVC encoding is selected is if the number of views in
upstream is equal or bigger than 2.
