Download Icon ScaleFilter	v1.1
Download Icon CropFilter	v1.0	The CropFilter is a DirectShow filter that can crop RGB24 and RGB32 media.
Download Icon 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.
Download Icon YUV420toRGBFilter	v1.0	This filter converts the custom packed YUV420 planar format back to RGB24.

This project provides an example as to how the DirectShow framework can be integrated with a RTP/RTCP/RTSP streaming library in order to stream live audio.

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 available in the download. The base class have been compiled into a static library which the user can reference in the project.

Filter Source Code

The download also contains the source code for the above-mentioned scaling, cropping and color conversion filters.

Image Utilities

The ImageUtils folder contains source code for various image processing such as cropping, scaling, etc. These files have been compiled into a static library which is also referenced by filters that require such functionality.
