Subject: [PATCH] [rbp/omxplayer] Avoid audio codec when in passthrough modes
|
||||
|
||||
There is no need to open the ffmpeg audio codec when in passthrough mode.
|
||||
Also there is no need to close/open the OMXAudio component when parameters (like number of channels) change in passthough.
|
||||
This avoids an unpleasant stutter
