Oh sorry that is what you mean. I added an entry "mediacodec" to the
decoders selection in playback profile entries. I added OpenGL as render
option to that.
I did not yet add a default playback profile for this. You have to
create a playback profile (called e.g. test) and add an entry with
decoder "mediacodec" and render of OpenGL, and select one of the
deinterlace methods available. When it is all working I will add a
default playback profile with name mediacodec-normal or similar.
From time to time while developing and testing I switch back to an
OpenGL profile that uses ffmpeg to make sure that it still works.
There still seems to be a problem with changes to playback profile not
taking immediate effect. I need to track that down. In the meantime I
restart the frontend to make sure my playback profile change takes effect.
