Mp4 File Format Features

Mp4 File format features consist of a mp4 file library and a series of utility functions.

  • mp4creator - this utility will:
    • create mpeg4 files from elementary streams (mp3, aac, mp4v, h263, h264 and .mpg files)
    • hint mpeg1/2/4, h264, h264 video, mp3 audio (rfc 2250 and 3119), AMR and aac audio
    • extract elementary streams from mp4 files (adding headers, if needed)
    • create and/or encrypt files to the ISMA 1.0 specifiation
    • create 3GPP files from H.263 and/or AMR files
  • mp4info - display information about tracks in mp4 file
  • mp4dump - dumps contents from mp4 files
  • mp4trackdump - dumps track information
  • mp4tags - sets iTunes tag information
  • mp4art - extract iTunes cover art
  • mp4videoinfo - dump information about video tracks in mp4 files

Encoding Tools

Because of other projects (lame, faac, ffmpeg) provide good command line tools, we only support xvidenc, which will encode mpeg4 video.

We do support the following:

  • lboxcrop - vertically crop raw video
  • rgb2yuv - convert RGB to YUV files
  • avi2raw - dump elementary streams from avi files

Other Tools

Mpeg4ip includes a number of debugging tools. These include:

  • yuvdump - display raw YUV file
  • avidump - display information about avi files
  • mpeg4vol - decodes an mpeg4 vol from command line or mp4 file
  • mpeg2video_parse - displays frame information about mpeg2 video elementary stream
  • h264_parse - displays information about h.264 elementary stream
