DirectShow Filters

Help 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.
