Class UniversalAutoDemuxerBlock

Namespace

VisioForge.Core.MediaBlocks.Demuxers

Assembly

VisioForge.Core.dll

Represents a universal automatic demuxer block that dynamically selects the appropriate demuxer based on the input stream format detected by typefind element.

Remarks

The UniversalAutoDemuxerBlock is a MediaBlocks component that automatically detects the format of an incoming stream and creates the appropriate demuxer dynamically. It uses GStreamer's typefind element to identify the media format and then instantiates the correct demuxer element on the fly.

Key features: - Automatic format detection using typefind - Dynamic demuxer creation based on detected format - Support for all common container formats (MP4, MKV, AVI, WebM, etc.) - Pre-created output pads based on constructor parameters - Configurable output stream selection (video, audio, subtitle, metadata)

Output pads are pre-created based on constructor parameters: - If renderVideo is true, creates 1 video output pad - If renderAudio is true, creates 1 audio output pad - If renderSubtitle is true, creates 1 subtitle output pad - If renderMetadata is true, creates 1 metadata output pad
