As far as I can see, very good news for those of us on a Google device wanting to upgrade to Android 6.0. I have just upgraded my 2013 Nexus 7 to 6.0 again, after upgrading then downgrading again a couple of weeks ago after experiencing the 'unfortunately Litchi has stopped' crashes.
I have upgraded Litchi to the latest public build and connected everything up on the kitchen table (the previous crashes happened regardless of whether the bird was in the air or not).
First, to sanity check the previous problem, I ran Litchi on the normal hw encoder. Low and behold it crashed almost immediately. Tried again and same result. I then changed the hw decoder to the new Android 6.0 decoder (it's an additional option now in the decoding options box).
I have now had it running for 15 minutes on both fpv and gs without a single hitch - it's as smooth as silk. Another side benefit seems to be that the map zoom is much more manageable when in pip mode, giving a wider view.
So, based on that less than extensive first test, kudos to the developers.....Yet again they appear to have responded quickly to a problem. If only all developers were like this......
