vidgear v0.1.8 Release Notes

Release Date: 2020-06-12 // almost 4 years ago

  • 🆕 New Features

    👍 Multiple Clients support in NetGear API:

    • Implemented support for handling any number of Clients simultaneously with a single Server in this mode.
    • Added new multiclient_mode attribute for enabling this mode easily.
    • Built support for zmq.REQ/zmq.REP and zmq.PUB/zmq.SUB patterns in this mode.
    • Implemented ability to receive data from all Client(s) along with frames with zmq.REQ/zmq.REP pattern only.

    - Updated related CI tests

    👌 Support for robust Lazy Pirate pattern(auto-reconnection) in NetGear API for both server and client ends:

    • Implemented a algorithm where NetGear rather than doing a blocking receive, will now:
      • Poll the socket and receive from it only when it's sure a reply has arrived.
      • Attempt to reconnect, if no reply has arrived within a timeout period.
      • Abandon the connection if there is still no reply after several requests.
    • Implemented its default support for REQ/REP and PAIR messaging patterns internally.
    • Added new max_retries and request_timeout(in seconds) for handling polling.
    • Added DONTWAIT flag for interruption-free data receiving.

    - Both Server and Client can now reconnect even after a premature termination.

    🐎 Performance Updates for NetGear API:

    • Added default Frame Compression support for Bidirectional frame transmission in Bidirectional mode.
    • Added support for Reducer() function in Helper.py to aid reducing frame-size on-the-go for more performance.
    • Added small delay in recv() function at client's end to reduce system load.

    - Reworked and Optimized NetGear termination, and also removed/changed redundant definitions and flags.

    📄 Docs Migration to Mkdocs:

    • Implemented a beautiful, static documentation site based on MkDocs which will then be hosted on GitHub Pages.
    • Crafted base mkdocs with third-party elegant & simplistic mkdocs-material theme.
    • Implemented new mkdocs.yml for Mkdocs with relevant data.
    • Added new docs folder to handle markdown pages and its assets.
    • Added new Markdown pages(.md) to docs folder, which are carefully crafted documents - based on previous Wiki's docs, and some completely new additions.
    • Added navigation under tabs for easily accessing each document.
    • New Assets:
    • Added Required Plugins and Extensions:
      • Added support for all pymarkdown-extensions.
      • Added support for some important admonition, attr_list, codehilite, def_list, footnotes, meta, and toc like Mkdocs extensions.

      • Added support for mkdocstrings plugin for auto-building each VidGear's API references.
      • Added python handler for parsing python source-code to mkdocstrings.
    • Auto-Deploy Docs with Github Actions:
      • Implemented Automated Docs Deployment on gh-pages through GitHub Actions workflow.
      • Added new workflow yaml with minimal configuration for automated docs deployment.
      • Added all required python dependencies and environment for this workflow.
      • Added master branch on Ubuntu machine to build matrix.
