_d_m_i_n_f_o is equivalent to "dmconvert -D".
In the case of MPEG-1 bitstreams, _d_m_i_n_f_o will display estimated lengths
for the audio and video tracks. (The only way to determine the exact
length of a track in an MPEG file is to parse the contents of the entire
file.)
Some file formats do not describe some aspects of the data they contain.
For example, an SGI image file does not describe the pixel aspect for the
sampled image, or whether the image originated as a single frame or as a
pair of interlaced video fields. In cases like these, the values of the
corresponding track parameters are not displayed.

Silicon Graphics Computer Systems. Portions developed at the San Diego
Supercomputer Center.
_d_m_i_n_f_o uses the SGI Audio File, Compression, ImageVision, and Movie
Libraries to access digital media data.
Many of the image file formats are supported through the San Diego
Supercomputer Center's image library (libim, libsdsc). This library is
available from anonymous ftp at sdsc.edu in the
/pub/sdsc/graphics/imtools/ directory. For more information, contact
info@sdsc.edu.
