- This subdirectory contains the Codec Installation Sample. This sample
- shows the developer of a video compression/decompresion algorithm how to
- have the algorithm installed into the MMPM/2 system so that it can then
- be used by the Digital Video Recorder to record software motion video.
-
- This sample should be used in conjunction with the sampcodc.dll file
- that is available in the \mmos2\mmtoolkt\samples\codec subdirectory.
-
- The files included with this sample are the following:
-
- vidrec.ico - The icon that shows up in the MINSTALL window next to
- the text title of the codec.
-
- control.scr - The first file read in by MINSTALL, which points to the
- master file list (master.dsk), defines the source and
- destination directory numbers, and all the file groups.
- In the example, there is only one file (hence only one
- group). The group definition defines the group number
- (to be used with the group number associated with the
- files in the master.dsk), the size of the group in KBytes,
- the name of the codec that appears on the MINSTALL line,
- the version of the codec, a pointer to .INI file update
- information, and default selection status.
-
- master.dsk - The main file describing the contents of the disk(s) that
- need to be installed. Each file to be installed has
- an entry defining the disk number that the file resides on,
- the group that the file is in, the number of the
- destination directory, the number of the source directory,
- and the filename itself.
-
- sampcodc.scr - Filelist control file containing the list of items to
- be added to the MMPMMMIO.INI file by MINSTALL. Some items
- of interest are the FourCC of the file format, the .DLL
- name, the .DLL entry point, the FourCC of the codec
- algorithm, the capabilities of the codec (shouldn't need
- updating), and the X and Y alignment definitions (which
- describes how the codec encodes data if it does so in
- blocks... this is important for decompression and window
- placement).
