Downloads A part of the objective of the Real-Time Video Coding group is to utilise open source frameworks and to contribute to the open source community as well as to provide source code that is available for general usage. Please send comments, feedback, suggestions to rtvc[at]meraka.org.za. DirectShow Filter Downloads The following DirectShow filters are available for download as DLLs. These need to be registered using the regsvr32 command. Download the documentation below for more information about the filters. Filter Version Description ScaleFilter v1.1 The ScaleFilter is a DirectShow filter that can scale RGB24 media to specified target dimensions. CropFilter v1.3 The CropFilter is a DirectShow filter that can crop RGB24 and RGB32 media. RGBtoYUV420Filter v1.0 This filter converts RGB24 or RGB32 media to a YUV4:2:0 Planar format whilst retaining the original VideoInfoHeader of the media. YUV420toRGBFilter v1.0 This filter converts the custom packed YUV420 planar format back to RGB24. Source Downloads • Base classes and interfaces - DirectShow base classes and interfaces have been written which simplify the creation of a transform filter. The CCustomBaseFilter class provides a base class for filters with a single input and output pin. The MultiIOBaseFilter project provides support for writing DirectShow transform filters with multiple input and output pins such as multiplexers and demultiplexers. All Meraka RTVC filters inherit these base classes, which are 216
