This callback is called when the client capabilities have been received. This callback
appears to be more useful than the Capabilities one that is called just before the server
sends its capabilities.
Dropped some warning that were caused by the DEBUG_CAPABILTIES define.
Also adjusted some lines that were quite ugly after the automatic truncation
to 80 characters.
Since not all H264 decoders support multiple YUV420 output
buffers process H264 decoding and YUV to RGB conversion
sequentially to avoid overriding the input data.
Currently supported source pixel formats are:
- PIXEL_FORMAT_BGRA32
- PIXEL_FORMAT_BGRX32
Support for PIXEL_FORMAT_RGB[XA]32 can simply be added if
required (see the comment in prim_YUV_opt.c).
On my old 3.1 GHz Core i5-2400 the new SSSE3 function can convert
over 900 1080p BGRX frames per second.
The current non-optimized C version (which supports all pixel formats)
can't do more than 40 yuv conversions per second on this cpu.

Also fixed an error in TestPrimitivesYUV which generated resolutions
with height or width set to zero

Currently it is not possible to cleanly install multiple major version
of FreeRDP concurrently as some of the development libraries (.so files)
files can conflict.
This change renames all libraries to include the major version number in
the library name to fix this limitation.
The list of changed libraries:
libwinpr-tools.so -> libwinpr-tools2.so
libwinpr.so -> libwinpr2.so
libfreerdp.so -> libfreerdp2.so
libfreerdp-client.so -> libfreerdp-client2.so
libfreerdp-shadow.so -> libfreerdp-shadow2.so
libfreerdp-server.so -> libfreerdp-server2.so
libfreerdp-shadow-subsystem.so -> libfreerdp-shadow-subsystem2.so
libuwac.so -> libuwac0.so
As the library names have changed, projects that use FreeRDP will need to
update their dependencies. -
If pkg-config or cmake find modules are used, reconfiguration might be
sufficient.
Fixes#3460
FreeRDP calculates default request size in server mode based upon
the desktop resolution. In practice, however, I've found clients (namely
MS Lync 2013) which would show only a black screen when the value is
greater than 0x3EFFFF.
This change allows to override the default in such special cases by
assigning a different value to server->settings->MultifragMaxRequestSize
after the shadow server structure is initialized in shadow_server_new().
Channels with regular and extended interface need to live in the same
handle name space otherwise they can't be uniquely identified in the
global channel manager.
SSL functions like OpenSSL_add_all_digests should be invoked at very beginning as they are not MT safe.
