Project Information

This is the Video Processing Project.

This project was registered on SourceForge.net on Mar 23, 2009, and is described by the project team as follows:

Video processing source code for algorithms and tools used in software media pipelines (e.g. image scalers, colour converters, etc.) The currently available source code is written in C++ with their associated libraries and DirectShow™ Filters.

Background

Filters

These are a set of general filters for scaling, cropping, colour conversion, etc. that are completed items and ready for use. The implementations provided are designed for use with Microsoft’s Direct Show™ framework and we have supplied some useful DirectShow™ base classes that further simplify the development effort.

The following filters are installed when running the Setup.msi download:

• Audio mixing filter
• Crop filter
• Framerate display filter
• H264 encoder filter
• H264 decoder filter
• H264 source filter
• Picture in picture filter
• RGB 2 YUV420P converter
• RTSP source filter
• Rotate filter
• Scale filter
• Video mixing filter
• Timestamplogging filter
• YUV source filter
• YUV420P 2 RGB converter

These filters can also be downloaded individually and registered using the regsvr32 command. In Graphedit they will then appear in the DirectShow™ category with the prefix "CSIR VPP". The filters can be configured using their property pages. The full source code is available in the subversion repository.

We encourage community contributions for faster implementations that sit behind the same interfaces.

Codecs

An H.264 video codec (encoding and decoding) is currently under development using a bottom-up design approach.

2012/03/03: The first version of the H.264 codec is going to be released within the next month!

2012/03/15: The first version of the H.264 codec has been released!

The source code for the low level codec tools will appear and then be added to, periodically. We would like to offer these while the code is being developed to encourage comments early on in the design. Some of these raw classes may also be useful for other implementations.

We would like the community to contribute in conformance testing to the H.264 standard and faster implementations that use the defined interfaces.

Please note that the use of the H.264 video standard may require the payment of license fees. These are governed by the MPEG Licensing Authority and the rules may be found at www.mpegla.com. It is your responsibility, not the authors of this source code, to ensure that you comply.

Filter overview

Audio mixing filter

Sample filter that shows how multiple PCM streams can be mixed together.

Crop filter

Filter that crops RGB media.

Framerate display filter

Filter that estimates framerate and overlays it on the video using GDI.

H264 encoder filter

An H.264 encoder that implements the baseline profile. -- More info on codec -- -- More info on DirectShow filter --

H264 decoder filter

An H.264 decoder designed for use with the provided encoder or H264 source filter. The decoder uses a custom media type which can be configured on the encoder and source filters. -- More info on codec -- -- More info on DirectShow filter --

H264 source filter

Source filter that can read raw .264 files. Foreman sample file More info

Picture in picture filter

Sample picture in picture filter.

RGB 2 YUV420P converter

RGB24 to YUV420 planar converter. This filter can be connected to a dump filter to create raw YUV files. More info

RTSP source filter

RTSP source filter that supports 8/16-bit PCM, AMR (via Monogram AMR filters), mp3 and H.264. This filter uses the liveMedia streaminbg library for RTSP/RTP/RTCP available at www.live555.com

Rotate filter

Filter that rotates video by 90, 180, 270 degrees, as well as mirroring vertically and horizontally.

Scale filter

Scale filter that supports up to 2x upscaling.

Video mixing filter

Sample video mixing filter that shows how multiple video streams can be mixed together.

Timestamplogging filter

Filter that logs sample timestamps to file with current time. This is useful to calculate DirectShow filter sample processing times.

YUV source filter

Source filter for raw YUV media such as videos from the standard test sequences. More info

YUV420P 2 RGB converter

YUV420Planar to RGB converter. Can be used in conjunction with the YUV source filter. More info
