Background
The objective of the Real-Time Video Coding group is to research and develop intelligent multimedia software components and delivery systems that adapt to congested and low infrastructure network environments. The emphasis is on jointly-optimised or co-operative behaviour between the delivery context, as in real-time network conditions, and the video/audio encoder rate control mechanisms. Innovative solutions are sought to enhance the Internet video experience in a developing world context where bandwidth is a scarce resource.
Current research within the group is concentrating on optimal and weighted context-based bit allocation techniques and implementations within international standard video codecs. A scalable and bandwidth adaptive multimedia broadcasting platform is under development to encompass the novelty of the bit allocation research.

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(dot)org(dot)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 |
|---|---|---|
 |
v1.1 | The ScaleFilter is a DirectShow filter that can scale RGB24 media to specified target dimensions. |
|
v1.0 | The CropFilter is a DirectShow filter that can crop RGB24 and RGB32 media. |
|
v1.0 | This filter converts RGB24 or RGB32 media to a YUV4:2:0 Planar format whilst retaining the original VideoInfoHeader of the media. |
|
v1.0 | This filter converts the custom packed YUV420 planar format back to RGB24. |
