Most games register a music channel, and when there is no music,
they still stream silence (and run through all the Converter::flow
code!). Scan the buffer for that to pause the AudioTrack. Ugly, but
worth it - reduces CPU usage on many games and hence saves battery life.
Only works in situations without any registered channels (or all paused)
at the mixer (like on the launcher or GMM).
CPU usage before (Galaxy Tab):
~5% scummvm
~15% mediaserver
After:
~2% scummvm
0% mediaserver
;)
The RateConverter::flow result was never used, pipe it through
Channel::mix to MixerImpl::mixCallback, so backends can decide
if they want to waste cpu cycles while playing empty buffers.
All backends that derive from BaseBackend are consoles and/or portables
without any connection from graphics modes to scalers.
The default implementation of resetGraphicsScale() is now a noop, which
seems correct for all current backends.
This fixes unwanted mode changes since 93fdcbfa.
If highres games pass defaultTo1XScaler=true to initGraphics(),
use resetGraphicsScale() instead of hardcoding "1x" (which doesn't
exist on the OpenGL backend)
If an OpenGL mode is selected, it now doesn't switch back to plain
SDL now for those games.
This reverts commit c8551b80dd917c35d367c1f15f4b9c2618da3684.
Turns out the flicking comes from an updateScreen() call in
android's clearScreen(). Besides, this broke GMM... a little
This is used when changing directories in the 'add game' dialog or when
choosing another tab in the option dialog. Only blit to the overlay on
the final pass. Gets rid of highly annoying flickers on androids
Instead of running into assert()s due to dumb parser decisions, use
'less than' and 'greater than' width/height conditions on the
'resolution' tags.
Seems better than listing >9000 different android resolutions.
This was probably set to ensure onCreateInputConnection() gets called,
but it is regardless of this flag. Now the soft keyboard doesn't show
up on startup on devices without physical keyboard, which prevents
unnecessary surface changes.
