* Mark WTSVirtualChannelOpen and WTSVirtualChannelOpenEx with
WINPR_ATTR_MALLOC to enforce compiler checks for resource cleanup
* Fix unused result warnings, use the result or cast to (void) where not
requierd
* Cast freerdp_load_channel_addin_entry return with a union (removes the
incompatible function pointer cast warnings)
* Typedef function pointers in tables.h
* generate a include header depending on where the soundcard.h file was
found as that is in system paths that must not be added to the include
search paths.
* fix detection, the if/else was mixed up and completely broken.
C requires prototypes or compilers will complain about them missing. Our
library entry points do not have such, therefore add the macro
FREERDP_ENTRY_POINT which declares the function prototype automatically
before the function.
The current server side channel handling of AUDIO_INPUT is currently
very constrained:
- Server implementations cannot measure the clients uplink, since the
Incoming Data PDU is currently unhandled and FreeRDPs DSP handling
delays the callback call of ReceiveSamples
- Servers currently cannot prefer a different protocol version
- Servers currently cannot change the used format
To solve these issues without running into the risk that some
simplifications constraint certain API usage, rework the current channel
handling to be very close to the documentation.
This means, that all documented API calls can be made by server
implementations and all documented PDUs, that the server side is
expected to receive are just parsed inside FreeRDP and then forwarded to
the API implementation.
* Fixed format strings to match arguments
Reviewed and replaced all %d specifiers to match proper type
* Added proxy dynamic channel command type to log messages.
pulse/alsa/oss do not reliably work with ALAW/ULAW codecs with all
hardware available.
Since these formats are poor quality anyway, deactivate them for
audin channel.
