Cedocida DV Codec

Introduction:

Cedocida is an open source Video for Windows (VfW) DV-Type2-Codec.

Features:

• supported formats for in- and output: RGB, YUY2, YV12 (DV / MPEG2-I / MPEG2-P)
• direct YV12 input/output without color shift, interpolation or conversion when using "YV12 (DV)" option
• optional forcing of selected input and output format
• settings for picture quality and compression methods

Description of selected settings:

• force input format
  If enabled, the encoder/decoder only accepts the selected format for input/output. This could result in an error message if the used application does not support this format.
  When disabled, the selected format is only the primary suggestion for the application that uses this codec.
  
• *YV12 chroma sampling
  The YV12 format is a planar YUV color format with 4:2:0 subsampling. The position of the chroma samples differs with the compression standard using it.
  Using the first option (DV), the pixel data is directly feed to or from the the compression algorithm without color shift, interpolation or conversion.
  For (MPEG 2 non interlaced) and (MPEG 2 non interlaced) the data is preprocessed or postprocessed in order to match the given color sampling positions.
  Some remarks on "YV12 (DV)" input/output option in combination with NTSC video:
  Because NTSC DV uses 4:1:1 subsampling type, you will see weird color when viewed with a normal YV12 program which assumes 4:2:0. This is no bug. If you need YV12 format for producing DVD content, use the option "YV12 (MPEG 2 *)".
  

Installation:

1. Uncompress the archiv to a temporary place.
2. Right click on "cedocida.inf" and select install
