Juergen Kuri updated GUACAMOLE-1413:
------------------------------------
Description:
h3. Context
We want to use the Guacamole RDP proxy server with full audio support using
# audio input redirection, rule {{enable-audio-input=true}}
# audio output redirection, rule {{disable-audio=false}}
In the source code, header file {{src/pulse/pulse/pulse.h}} we see the
following constants for Pulse Audio library parametrising the PCM modulator of
the RDP server:
{code:c}
/**
* Rate of audio to stream, in Hz.
*/
#define GUAC_PULSE_AUDIO_RATE 44100
/**
* The number of channels to stream.
*/
#define GUAC_PULSE_AUDIO_CHANNELS 2
/**
* The number of bits per sample.
*/
#define GUAC_PULSE_AUDIO_BPS 16
{code}
h4. Problem
Parameter of interest:
* {{GUAC_PULSE_AUDIO_CHANNELS 2}}
For remote users with an internet connection with low network bandwidth, it
might be useful to have sessions with just *_one_* audio channel, mono instead
of stereo expecting utilising just half of the network bandwidth for the part
of audio blob transmission.
Is this assumption correct transmitting just one audio channel would half the
network bandwidth utilisation for audio blobs?
h3. Feature
Add another rule parameter for an individual RDP server session
* for database table {{guacamole_connection_parameter}}
which allows us to parametrise the number of simultaneous audio channels to be
transmitted *_in both redirections_*, audio in- and output.
Possible parameter names might be:
* {{disable-audio-stereo}}, default {{false}}
* {{enable-audio-mono}}, default {{false}}
* {{audio-channels}}, {{\{1\|2\}}}, default {{2}}
If this is not feasible or difficult to implement for some reasons, add a
corresponding parameter to daemon configuration file
* {{guacd.conf}}
* or {{guacamole.properties}}
affecting all RDP sessions in the same way.
