DirectShow Filters

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.

Frame Rate Corrector - for changing the frame rate of video stream, special support of interlaced video.
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 and Frame Rate Corrector - possibly Video Corrector.
Video Synchronizer - for synchronize two or more video streams (keep the same rate, frame by frame synchronization).
Pause - pause video/MLPK stream and repeat last frame during pausing (the graph still running).
SmartTee - MediaLooks implementation of Smart Tee filter with separate stream for preview and ability to turn on/off preview stream.
Rotate - rotate video on 90, 180, 270 degree, may flip video (vert. horz.), interlaced video support (with correct fields order).
Rate Keeper - keep rate of incoming video.

AsynchReader with DRM
IP Source
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?
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.
Color Adjustment (?) Brigthness/Contrast/Sharpness/Gain/Black

Level/White Level/Saturation/Gamma, R/G/B, Y/U/V
