Document dump .dot API's

Imp single source pause-resume

Implement PrimaryGieBintr

Makefile updates

Better manage obj files so they are not mixed src's ... and need to exclude all Catch test objs when building lib

Document Primary and Secondary GIE APIs

Refactor Bintrs moving functionality into new Elementr class

Imp Pipeline state management

Add API reference for Pipeline Management

Setup Python examples folder

Create first example and document.

Latest update (11/10/2019) crashes gstreamer

@rjhowell44
After the latest commits, executing the script below:
python3 ds_test1.py sample_720p.h264

causes this error message:

(python3:9865): GStreamer-CRITICAL **: 12:02:58.754: gst_element_add_pad: assertion 'GST_IS_ELEMENT (element)' failed
terminate called without an active exception
Aborted (core dumped)

If I revert back to commit 039f396, then the error does not occur.

Update API reference

Updates for latest API commits

Upgrade DslApi.h to use UNICODE for all input

All char* parameters and return values need to be updated to wchar_t* to work properly for Python3.
This one should have been obvious from the beginning. :-|

Integrate PrimaryGieBintr into PipelineBintr

Imp dsl_pipeline_new_many

Update Pipeline API reference for add/remove event handler

Refactor container hierarchy

Update API reference with Pipeline CB types

Implement Component API

Implement

• dsl_component_delete
• dsl_component_delete_many
• dsl_component_delete_all
• dsl_component_list_all

reserve dsl_component_copy for when each component's copy method has been implemented

Setup API Test

• Add catch.hpp
• Create first test cases
• Publish first results
• Add documentation on
  • downloading TS runner - install deps
  • running catch
  • JUnit output
  • pushing to TS branch, with git links

Imp dsl_return_value_to_string

Implement Secondary GIEs

Add Source test coverage for IsLive and IsInUse

Complete pipeline container management

Complete the following API's

• dsl_pipeline_new
• dsl_pipeline_delete
• dsl_pipeline_delete_many
• dsl_pipeline_delete_all
• dsl_pipeline_list_all

Add API reference for add/remove state-change-listener

Implement Dewarper

Complete Pipeline Play, Pause, Stop

Imp source-id and max-source mgt

Python example, creating URI sources from folder

@Sscsmatrix I thought of an interesting Python example that would accomplish a couple of things. Here's a list of items/steps if your good with this.

• Setup examples source folder
  • ./examples/videos
  • ./examples/python
• Populate the videos folder with a number mpeg and jpeg files ( > 10 would be great)
• Develop a Python example where... given a folder path, iterate through the list of files in the folder creating a URI source for each. Use the relative path for the URI, and filename as the unique source name. There is no practical limit to how many source objects can be created, just how many can be used by Pipelines at one time.

I'm working on a couple of dependencies first, and will let you know when done.

Complete Pipeline Sinks Bintr

Implement display event handler add/remove

Implement the following API's

• dsl_pipeline_display_event_handler_add
• dsl_pipeline_display_event_handler_remove

Fix primary GIE deserialization errors on load model engine

@Sscsmatrix the Primary GIE issues I was having were related to config and model file issues. Strangely enough, I'm unable to run the combination of

• test/config/config_infer_primary_nano.txt
• test/models/Prmary_Detector_Nano/resnet10.caffemodel
  ... results in deserialization errors when loading the engine on Play

However, the combination of

• test/config/config_infer_primary.txt
• test/models/Prmary_Detector/resnet10.caffemodel_b1_fp16.engine
  ...seems to work for me... pretty sure I bought a Nano

I'll try and search the dev.talk when I get a chance, but glad to be finally moving past this issue.

I'm working on the OSD boxing next so we can visually verify.

Abstract shared pointer syntax for Bintr and Elementr

Implement Pipeline dump dot services

Implement with test

• dsl_pipeline_dump_to_dot
• dsl_pipeline_dump_to_dot_ts

Refactor UNICODE to ASCII string conversion

Implement state change listener methods

implement

• dsl_pipeline_state_change_listener_add
• dsl_pipeline_state_change_listener_remove

Create Python wrapper to check inputs

Need to add the python module to enforce typesafe parameter usage, to map the callback registration functions, and handle the **wchar_t parameters and returns.

Update API reference for upgrade to UNICODE

Add build variant to MakeFile

Need build option to build obj's into a static lib. Something like

$ make lib

or whatever approach works best

Remove unnecessary make include paths

Debug PrimaryGieBintr init settings

Research simplest, cleanest option for including and calling lib from Python

I'm hoping something like CTYPES will work. This issues is dependent on #7

All C function defined in DslApi.h should be easily callable. All functions use and return simple intrinsic types only (char, unit). The Component

Should be lots of info online. Add finds to issues

Move to pre-compiled headers

Extern "C" all public functions in DslApi.h

Research RTSP

@Sscsmatrix while you're waiting on functionality, I thought you might want to take on another little research project. It would be helpful if we had a better understanding of the Real-Time Streaming Protocol (RTSP).... info on

• what it is and what it's used for,
• why it's important for what we're doing
• what types of applications uses it
• who's using it on GitHub

Refactor UnLink functions

Add more test coverage for DisplayBintr
