First Requirement is for an uncompressed FOURCC codec to create AVI files.
It will take in RAW Bayer video, and store it uncompressed.
(RAW Bayer video is essentially stored the same as a 12-bit grayscale image.)
At this point it will store video only – no audio.
The standard resolution will be 1920pixels x 1080pixels – normal HD resolution, but it should be capable of storing at other resolutions.
When the AVI file is played back, there should be two variable user-selected options.
1.Bayer Sensors vary in the order of the pixels. The user can select RGBG, GBGR or RGGB.
2.The codec should be able to output the full 12-bit RAW file, unaffected, or it should have an option to debayer and output as an RGB image. The debayer does not need to be a complex algorithm but could be 'nearest neighbor'.
The codec should be a standard FOURCC codec, such that a standard media player such as VLC can play back the file with the codec installed.
The Second Requirement is for a utility that will convert an AVI file recorded with the codec into a RAW CinemaDNG sequence with no loss of quality.
We will supply sample data.
CinemaDNG can be implemented by the libtiff library.
Payment will be made in two installments – 40% after delivery of the first requirement – and 60% after delivery of the second requirement.

We will only consider bidders who have proven experience in the required areas of codec development, including FOURCC, ffmpeg, Directshow, etc.
We feel we have supplied enough information above for you to respond to the brief.
Please give an idea of what approach you would take, and what experience you have directly in the area of video.
If you have a question about the brief, please let us know, and we will respond.
