  • StreamGear:
    • The terminate() method is now formally deprecated and will be removed in a future release. The close() method should be used instead for safer process termination.
Bug-fixes
  • Various minor bug fixes and improvements across the codebase as part of the type hint additions and dependency updates.
  • Fixed YAML syntax error in GitHub issue templates (proposal.yaml and question.yaml) by changing labels from string to array format.
  • Updated .gitignore to replace the short project-specific list with the comprehensive standard Python .gitignore template, covering build artifacts, virtualenvs, test outputs, tool caches, IDEs, and packaging metadata.

Breaking Updates/Changes
  • StreamGear:
    • Deprecated terminate() method and introduce close() method.

Breaking Updates/Changes
  • ScreenGear:
    • Previously enforced threaded queue mode is now completely removed, resulting in a potential performance boost.
      • 💬 Reason: The IO is automatically blocked by the screen refresh rate, so adding the overhead of maintaining a separate queue is pointless.
    • Removed the THREAD_TIMEOUT optional flag.
Bug-fixes
  • WebGear_RTC:
    • Fixed a bug caused by PyAV's error when ndim==3 grayscale frames are encountered.

  • ScreenGear:
    • Fixed backend not defined while logging.
  • Setup.py:
    • Starting from version 8.0.0, the python-mss library dropped support for Python 3.7, so as a temporary measure, mss dependency has been pinned to version 7.0.1.

Breaking Updates/Changes
  • WriteGear:
    • Renamed output_filename string parameter to output.
      • Since WriteGear API accepts all sorts of streams (such as valid filename/path/URL) for encoding, thereby changing parameter name to output will be more true to its purpose.

Bug-fixes
  • Camgear:
    • Fixed CamGear.read() blocked unnecessarily.
      • 💬 When THREADED_QUEUE_MODE is enabled CamGear.read() blocks for an excessive duration when attempting to read past the end of a stream.
      • Added None frame to the queue at the end to signal we're done.
      • Added terminate Event check before continuing.
    • Fixed deadlock on exit.
      • 💬 The deadlock is due to self.__queue.get(timeout=self.__thread_timeout) line in read() method, which still waits for timeout(thread_timeout) to happen when main update() thread was already terminated on exit and queue was empty. Since there was no way to signal queue that stream is already ended, the blocking queue.get() keeps on waiting until timeout occurs.
      • The solution was to signal queue.get() that stream is already ended by putting None in queue on exiting the main update() thread.
  • ScreenGear:
    • Fixed ScreenGear.read() blocked during cold startup.
    • 💬 During startup, ScreenGear.read() doesn't checks if queue is empty before continuing.

    • Now ImportError will be raised only any certain API specific dependency is missing during given API's initialization.
    • New import_dependency_safe to imports specified dependency safely with importlib module.
    • Replaced all APIs imports with import_dependency_safe.
    • Added support for relative imports in import_dependency_safe.
    • Implemented error parameter to by default ImportError with a meaningful message if a dependency is missing, Otherwise if error = log a warning will be logged and on error = silent everything will be quit. But If a dependency is present, but older than specified, an error is raised if specified.
    • Implemented behavior that if a dependency is present, but older than min_version specified, an error is raised always.
    • Implemented custom_message to display custom message on error instead of default one.
    • Implemented separate import_core_dependency function to import and check for specified core dependency.
    • ImportError will be raised immediately if core dependency not found.

v0.1.9 (2020-08-31)

New Features
  • StreamGear API:
    • New API that automates transcoding workflow for generating Ultra-Low Latency, High-Quality, Dynamic & Adaptive Streaming Formats.
    • Implemented multi-platform , standalone, highly extensible and flexible wrapper around FFmpeg for generating chunked-encoded media segments of the media, and easily accessing almost all of its parameters.
    • API automatically transcodes videos/audio files & real-time frames into a sequence of multiple smaller chunks/segments and also creates a Manifest file.
    • Added initial support for MPEG-DASH (Dynamic Adaptive Streaming over HTTP, ISO/IEC 23009-1).
    • Constructed default behavior in StreamGear, for auto-creating a Primary Stream of same resolution and framerate as source.
    • Added TQDM progress bar in non-debugged output for visual representation of internal processes.
    • Implemented several internal methods for preprocessing FFmpeg and internal parameters for producing streams.
    • Several standalone internal checks to ensure robust performance.

      • Implemented Single-Source and Real-time Frames like independent Transcoding Modes.
      • Linked -video_source attribute for activating these modes
      • Single-Source Mode, transcodes entire video/audio file (as opposed to frames by frame) into a sequence of multiple smaller segments for streaming
      • Real-time Frames Mode, directly transcodes video-frames (as opposed to a entire file), into a sequence of multiple smaller segments for streaming
      • Added separate functions, stream() for Real-time Frame Mode and transcode_source() for Single-Source Mode for easy transcoding.
      • Included auto-colorspace detection and RGB Mode like features (extracted from WriteGear), into StreamGear.
    • New StreamGear Parameters:
      • Developed several new parameters such as:
        • output: handles assets directory
        • formats: handles adaptive HTTP streaming format.
        • custom_ffmpeg: handles custom FFmpeg location.
        • stream_params: handles internal and FFmpeg parameter seamlessly.
        • logging: turns logging on or off.
      • New stream_params parameter allows us to exploit almost all FFmpeg parameters and flexibly change its internal settings, and seamlessly generating high-quality streams with its attributes:
        • -streams (list of dictionaries) for building additional streams with -resolution, -video_bitrate & -framerate like sub-attributes.
        • -audio for specifying external audio.
        • -video_source for specifying Single-Source Mode source.
        • -input_framerate for handling input framerate in Real-time Frames Mode.
        • -bpp attribute for handling bits-per-pixels used to auto-calculate video-bitrate.
        • -gop to manually specify GOP length.
        • -ffmpeg_download_path to handle custom FFmpeg download path on windows.
        • -clear_prev_assets to remove any previous copies of SteamGear Assets.
    • New StreamGear docs, MPEG-DASH demo, and recommended DASH players list:
      • Added new StreamGear docs, usage examples, parameters, references, new FAQs.
      • Added Several StreamGear usage examples w.r.t Mode of Operation.

      • Added Adaptive-dimensional behavior for Demo-player, purely in css.
      • Hosted StreamGear generated DASH chunks on GitHub and served with raw.githack.com.
