Multimedia Services for Digital UNIX V1.6 for Digital UNIX

Dear Multimedia Services Customer:

This new version includes the following:

• Support for the FullVideo Supreme JPEG video card (AV321) with JPEG support on the AlphaStation workstation.
• Support for two FullVideo Supreme and FullVideo Supreme JPEG boards in a single system, including heterogeneous support.
• The Indeo software codec now supports the streaming ICM interfaces.
• Improved throughput for the Sound and Motion J300 and FullVideo Supreme (AV301) devices. This should help overall performance for applications that perform multiple types of concurrent operations, such as teleconferencing applications.
• The Indeo compressor can now compress 24-bit Ximage data.
• The JPEG software codec can now render YUV and YVU9 data to 8-bit Ximage data through the ICDecompress interfaces.
• Expanded the API for videoSetFieldMode and videoGetFieldMode with field mode dominance support.
• Enhanced audioplay to play back RIFF AVI files that contain audio data.
• Modified avirecord to do software compression in the post processing phase. It captures YUV or YVU9 data up front, and then when the file is being written out in AVI file format, it will compress as well. This allows users to record synchronized audio and compressed video data when using the FullVideo Supreme (AV301) option card.
• Enhanced DECsound (decsound) with some new features:
  • Added -device command line option to allow audio device selection
  • Expanded wave file support for various sample rates and formats
• Audio Control supports variable formats for VU meter.
• Enhanced AlphaVCR (alphavcr) with a variety of new features:
  • Play File automatically differentiates an AVI file from an MPEG file
  • Variable video window sizes
  • Record rate selection and record statistics
  • Improved performance for playing files, especially with Software JPEG
  • Decompression device selection for Play File
