|
|
* Took out the legacy NLSML interface.
|
|
* Fixed a gcc warning for strict-aliasing rules.
|
|
* Implemented apt_pair_array_generate() in 2 passes, apr_pstrcatv() alike.
|
|
* Prevent compilation warnings for unused-but-set-variable.
|
|
* Use int instead of apt_task_msg_type_e to suppress a warning triggered by gcc 4.7: case value not in enumerated type 'apt_task_msg_type_e'.
|
|
* Upon creation of a new memory pool, register apr_abortfunc_t callback which is supposed to be invoked when memory allocation fails within apr_pool.

|
|
* Unified pointer logging in APT style. Thanks Vali.
|
|
* Define APT_PTR_FMT as 0x%I64x for 64-bit Windows.
|
|
* Removed unused function apt_text_boolean_value_insert/apt_boolean_value_insert (inconsistent declaration/definition). Thanks Vali.
|
|
|
|
MPF library
|
|
|
|
* The function mpf_codec_lists_intersect() now returns FALSE if there is no match for the primary codec descriptor.

|
|
* Do not set SO_REUSEADDR on RTP sockets.
|
|
* Made G.711 implementation bit-exact with ITU-T reference implementation.
|
|
* Use APR typedefs in G.711 implementation.
|
|
* Improved the RTP port management for those cases when the specified RTP port range is not enough to handle concurrent MRCP sessions.

|
|
|
|
MRCP client library
|
|
|
|
* Completed the implementation of the new API function to retrieve a SIP/RTSP response code received from the server (Issue-90).
|
|
* Fixed a potential crash of the client stack which could happen when the server unexpectedly closes the MRCPv2 connection while the client stack is processing an application request.
|
|
* Allow a pool/factory of signaling agents to be defined with the MRCPv1 and/or MRCPv2 profiles.

|
|
* Store the profile name not only as a key in the profile table but also in the profile structure.
|
|
* Allow setting an arbitrary tag to the profile.
|
|
|
|
MRCP server library
|
|
|
|
* Handle separately the case when an RTSP SETUP contains no SDP, which means it's up to the server to decide which codec to use.
|
|
* Fixed a crash if MRCP resource not found. Thanks Vali.
|
|
* Keep track of associations between RTP termination factories (pools of RTP ports) and media engines.

|
|
|
|
ASR Client application (and library)
|
|
|
|
* Get rid of 1Kb grammar file limit in libasrclient. Load the content into an allocated buffer instead.

|
Changes for UniMRCP-1.1.0
|
|
|
|
APR-toolkit library
|
|
|
|
* The function apt_log_file_open() makes a copy of dir_path and file_name variables passed from a user application.
|
|
* Applied a patch to the apt_log routine which allows the log file to be appended instead of being overwritten. The patch was submitted by Dani. Thanks.

|
* Fixed the formatting of float values in the header fields. Applied a patch submitted by Randy (Issue-108). Thanks.
|
|
* Fixed apt_log_output_mode_check() which returned TRUE if any mode was enabled or checked regardless their correspondence. Thanks Vali.
|
|
* Enhanced the debug output by adding task message identifier to the log statements "Signal Message" and "Process Message".
|
|
* Fixed a potential crash related to the use of pollsets.
|
|
* Fixed a potential buffer overflow in apt_text_pair_array_insert(). Thanks Vali.
|
|

|
|
|
|
MPF library
|
|
|
|
* Tweaked DTMF detector's energy thresholds to eliminate false positives during in-band (from audio) DTMF detection. Thanks Vali.
|
|
* Took into consideration the RTP marker in order to re-sync the jitter buffer on a new talkspurt. Audio data loss could be experienced in the RTP receiver in case of consecutive SPEAK (for client) or RECOGNIZE (for server) requests.
|
|
* Instead of discarding a non-aligned RTP packet, adjust the timestamp and write available frames to the jitter buffer (Issue-122).
|
|
* Added support for the adaptive jitter buffer. Applied a reworked patch submitted by Erik. Thanks.
|
|
* Enhanced the detection of a new RTP talkspurt by implicitly setting the RTP marker if a gap between two RTP packets is more than the specified threshold (INTER_TALSKPUSRT_GAP = 1000 msec).
|
|
* Allow the initial playout delay in the jitter buffer to be set to 0.
|
|
* Implemented a time skew detection algorithm for RTP streams. The detection can be enabled and used for both the adaptive and static jitter buffer.
|
|
* Added support for redirection of RTP traces (RTP_TRACE, JB_TRACE) to the debug output window of Visual Studio.
|
|
* Enhanced the processing of the RTP named events.
|
|
|
|
RTSP library
|
|
|
|
* Use strcasecmp() instead of apr_strnatcasecmp() to match RTSP resource names (Issue-94).
|
|
* Fixed a crash in the RTSP client stack when the server closes a TCP connection while the associated RTSP session is being destroyed (Issue-124).
|
|
* Fixed the processing of RTSP TEARDOWN requests being timed out. Applied a patch submitted to Issue-125 by Chris. Thanks.
|
|
* For logging purposes, pass a string identifier of the RTSP/MRCPv1 signaling agent to the RTSP client and server stacks.
|
|
|
|
MRCP common library
|
|
|

|
|
|
|
MRCP client library
|
|

|
* Added a new accessor function to the client API to get an audio stream associated with the specified channel. The function name is mrcp_application_audio_stream_get().
|
|
* Added the ability to retrieve an external object associated with the MRCP session through the log handler (apt_log_ext_handler_f).
|
|
* Fixed the processing of a response to the SIP OPTIONS request used for resource discovery (Issue-112).
|
|
* Added a new constructor function unimrcp_client_create2() which allows to pass the client XML configuration not by a file, but rather by a string parameter. Thanks Vali.
|
|
* Fixed the processing of more than one pending application requests upon reception of a SIP BYE message from the server.
|
|
* Fixed the loading of the client configuration parameter <offer-new-connection>.
|
|
* Respond to client user application requests with failure if a new session couldn't be created due to an error in initialization of the SIP stack (Issue-127).
|
|
* When originating an offer from the client, take into account capabilities of an audio stream created by the client user application.
|
|
* Added a new function to the client API to retrieve a SIP/RTSP response code received from the server (Issue-90). The support is incomplete.
|
|
|
|
MRCP server library
|
|
|
|
* Fixed an interoperability issue with AVP. The mid attribute is not required when the SDP contains only one m-line.
|
|
* Fixed the build of C++ MRCP plugins for platforms other than Win32. Thanks Vali.
|
|

|
|
* Added support for Sofia-SIP's TPTAG_LOG() and TPTAG_DUMP() tags which can be enabled from the client and server configuration to print out and/or dump SIP messages.
|
|
|
|
PocketSphinx plugin
|
|
|
|
* In the PocketSphinx plugin, instead of using one common timeout for detection of speech activity and inactivity, use two different timeouts: one for activity and the other for inactivity detection.
|
|
* In the recognition results sent from the PocketSphinx plugin, set both <instance> and <input> elements.
|
|
* Fixed a race condition in the PocketSphinx plugin which caused the server to crash.
|
|
* Fixed the use of recognition timer in the PocketSphinx plugin.
|
|
* Set an MRCP version specific completion cause in the PocketSphinx plugin.
|
|

|
|
* Set the libtool parameters link_all_deplibs and link_all_deplibs_CXX to "yes" by default, with an option to disable them (--disable-interlib-deps), if ever needed. This fixes a link error on recent Debian/Ubuntu distributions.
|
|
* Modified the apr.m4 and apu.m4 macros to use '--link-ld' instead of '--link-libtool --libs' for the APR library dependencies. This addresses the problem with a wrong -L path to the expat library.
|
|
* Set prerequisite version for autoconf to 2.59.
|
|
