DirectShow Filters

• AsynchReader with DRM
• Audio Selector or Stream Selector (?) - switches between several audio channels (like Audio Mixer, but simpler.
• DV Scene Detector - reads a DV stream and writest to an XML file the date and time of the available scenes.
• File Writer with Cashe - helps eliminate HDD load when writing, thus helps reduce number of lost frames on HDD-intensive tasks.
• RTP Sink/Source
• GXF Splitter
• DICOM Splitter
• WPF Extender - see MediaElement & DirectShow
• Text Source - aka title generator (?) - generate images from text files (font, size, etc.), works in pair with Text & Graphics Overlay
• VBI Wrapper\Unwrapper - anybody remembers what it is? something about reading subtitles?
• Frame Rate Corrector - for changing the frame rate of video stream, special support of interlaced video.
• Buffer (need to change name) - trans filter for buffering media samples (useful e.g. for peak CPU load). Buffers IMediaSample without memory copy operations. With thread separation (?).
• Dump - writest incoming samples to hard disk. Also corrects MPEG2_TRANSPORT_STRIDE to

MPEG2_TRANSPORT.

• Fields Corrector - sets interlacing flags on incoming video based on frame rate or user selection.
• Scan Line - changes fields order (PAL->NTSC, NTSC->PAL, swap fields). Need to add 486 -> 480 conversion for DeckLink. This filter needs to be merged with Fields Corrector - possibly Video Corrector.
• MediaLooks ASF Reader - reverse playback; support of WMV features (deinterlacing, timecode, etc.); better support of network streams (HTTP/MMS/RTP etc.)
• MultiThread Encoder
• AVI Splitter + Frame Reorder - for reverse playback of AVI files; needs to be tested as DS filters and property page added.
