v0.08.alpha Overview

The release includes new features and bug fixes, as detailed below. Some of the updates include breaking changes!

VSCode configurations C++/Python linting, building and debugging (#341)

Visual Studio Code configuration files for remote arm64 building and debugging

RTSP Stream Re-connection Management.

An additional parameter was added to the RTSP Source constructor to allow the client to specify a new-buffer-timeout as follows:

/**
 * @param[in] timeout time to wait between successive buffers before determining the 
 * connection is lost. Set to 0 to disable timeout.
 */
DslReturnType dsl_source_rtsp_new(const wchar_t* name, const wchar_t* uri, uint protocol,
    uint cudadec_mem_type, uint intra_decode, uint drop_frame_interval, uint latency, uint timeout);

Two new Timeout services have been added

  • dsl_source_rtsp_timeout_get
  • dsl_source_rtsp_timeout_set

Along with two new default

/**
 * @brief time to sleep after a failed reconnection before
 * starting a new re-connection cycle. In units of seconds
 */
#define DSL_RTSP_RECONNECTION_SLEEP_S                               4
/**
 * @brief the maximum time to wait for a RTSP Source to
 * asynchronously transition to a final state of Playing.
 * In units of seconds
 */
#define DSL_RTSP_RECONNECTION_TIMEOUT_S                             30

With new services to get/set both at any time.

  • dsl_source_rtsp_reconnection_params_get
  • dsl_source_rtsp_reconnection_params_set

The client can add/remove a state-change-listener (callback) to each source to be notified of "changes in state" which occur during the connection/loss/re-connection cycle

  • dsl_source_rtsp_state_change_listener_add
  • dsl_source_rtsp_state_change_listener_remove

Re-connection stats can be obtained/cleared for each Source at any time.

  • dsl_source_rtsp_reconnection_data_get
  • dsl_source_rtsp_reconnection_data_clear

New Pipeline error-message-handler services #358

  • (*dsl_error_message_handler_cb)
  • dsl_pipeline_error_message_handler_add
  • dsl_pipeline_error_message_handler_remove
  • dsl_pipeline_error_message_last_get

Tiler and XWindow services and bug fixes.

New Services

  • New Tiler service to show a single source based on positional selection #345 dsl_tiler_source_show_select
  • New Tiler service to cycle through each source based on a time interval #348 dsl_tiler_source_show_cycle
  • New XWindow services, dsl_pipeline_xwindow_fullscreen_enabled_get and set to support XWindow full-screen mode #374

Bug Fixes

  • Fix current implementation of dsl_pipeline_xwindow_dimensions_get #354
  • Window Sink offset values are ignored on internal XWindow create #360

Map NvDsSRRecordingInfo to python class using CTypes #357

The callback type (*dsl_record_client_listener_cb) in both dslapi.h and dsl.py now use the new DslRecordingInfoType as the input parameter to the client's callback function, vs the previous opaque void pointer. The session info can now be accessed directly when using python. No need for NVIDIA python bindings.

Additional Bug Fixes

  • Error and segmentation fault on quitting application when rtsp-tap is added #352
  • Capture Frame Action - Segmentation Fault - 8 Cameras #339
  • Add button id to button-press callback #340
