StreamGear API: Real-time Frames Mode⚓
When no valid input is received on
-video_source attribute of
stream_params dictionary parameter, StreamGear API activates this mode where it directly transcodes real-time
numpy.ndarray video-frames (as opposed to a entire video file) into a sequence of multiple smaller chunks/segments for adaptive streaming.
This mode works exceptionally well when you desire to flexibility manipulate or transform video-frames in real-time before sending them onto FFmpeg Pipeline for processing. But on the downside, StreamGear DOES NOT automatically maps video-source's audio to generated streams with this mode. You need to manually assign separate audio-source through
-audio attribute of
stream_params dictionary parameter.
For this mode, StreamGear API provides exclusive
stream() method for directly trancoding video-frames into streamable chunks.
New in v0.2.2
Apple HLS support was added in
Real-time Frames Mode is NOT Live-Streaming.
NEVER assign anything to
stream_paramsdictionary parameter, otherwise Single-Source Mode may get activated, and as a result, using
stream()function will throw
You MUST use
-input_framerateattribute to set exact value of input framerate when using external audio in this mode, otherwise audio delay will occur in output streams.
Input framerate defaults to
-input_framerateattribute value not defined.
