I'm sure the problems I am having relate to how libcec works with the
various manufacturers implementation of the standard. I have been using
the debug logs from both mythfrontend and cec-client and your code is
obviously making the correct calls but my Panasonic TV does not
understand. During one test mythfrontend saw the left arrow key and some
numbers but the other arrow keys didn't work. I'm sure the inconsistency
from one test to the next is because the device is not registered
properly with the TV.
There are others on the pulse eight forums making similar comments about
problems their xbmc systems and Panasonic. The latest version of the
library is starting to take account of other manufacturers differences
so hopefully Panasonic will come soon.
As per my comment on IRC your library version check is inverted as I got
the following messages
CoreContext cecadapter.cpp:131 (Open) - CECAdapter: You need at least
libcec version 7 (found 8).
CoreContext cecadapter.cpp:198 (Close) - CECAdapter: Closing down CEC.
When I swapped the > for a < all was well.
