Overview

The IBM MPEG-4 Audio Video Content Generator Tool generates MPEG-4 streamable files compatible for use with MPEG-4 compliant devices.

The Tool combines audio and video media files into a single MPEG-4 file. The MPEG-4 file can be the standard MPEG-4 binary files, hinted MPEG-4 binary files, MVR MPEG-4 and MPEG-4 Multiplex stream ready MPEG-4 files. The standard MPEG-4 files are suitable for exchanging MPEG-4 content between authors. Hinted MPEG-4 files are suitable for streaming from RTP/RTSP servers. The tool supports adding both ISMA compliant media and other popular media content into a hinted MPEG-4 file. The hinted MPEG-4 file is compatible for use with ISMA compliant devices. Note: although the tool allows the addition of other popular media types, other than just ISMA compliant media, in practice the use of such content is dependent on having available devices supporting such additional capabilities beyond the scope that ISMA defines for compliant interoperability. Check the device specifications with regards to additional popular media types. MVR MPEG-4 and MPEG-4 Multiplex streamable files can be streamed across the internet from a standard HTTP server.

The various audio and video objects, along with the file types in parentheses, that are supported are:

  • Video
    • ISMA compliant:
      • MPEG-4 video (.cmp, .m4v, .263 & .mp4)
  • Audio
    • ISMA compliant:
      • MPEG-4 AAC audio (.aac, .adif & .mp4)
    • Additional types:
      • mp3 audio (.mp3)
      • G.723 audio (.723)

The following figure shows the user interface.

1. Menu Bar

The following list identifies the menu options:

2. Window

The client area window for the IBM MPEG-4 Audio Video Content Generator Tool is divided in 3 sections:

  • The Input Files section is for entering the audio and video file names.
  • The Output File section is for entering the name and type of the MPEG-4 file to be generated.
  • The Creation section contains the interface to create a MPEG-4 file and monitor its status.

3. Command line

The IBM MPEG-4 Audio Video Content Generator Tool supports a Command Line interface. The input and output files can be specified along with the quiet (-q) option on the command line to allow a batch generation of hinted MPEG-4 files. For example:

AVgen video.m4v audio.adif ouput.mp4 -q
