NAME ^

Video::OpenQuicktime - An interface to the OpenQuicktime library.

SYNOPSIS ^

  use Video::OpenQuicktime;

  my $qt = Video::OpenQuicktime->new(file=>"sample.mov");
  $qt->get_video_height;
  $qt->get_audio_compression;
  $qt->get_audio_samplerate;

DESCRIPTION ^

From the OpenQuicktime site, http://www.openquicktime.org:

"OpenQuicktime aims to be a portable library for handling Apple's QuickTime(TM) popular media files on Unix-like environments. It is aim is to provide encoding, authoring and editing support as well as video playback."

OpenQuicktime is currently able to decode as well as encode video and audio streams. The Video::OpenQuicktime library currently only supports extracting diagnostic information from Quicktime files, such as video dimensions, codecs used, and play length.

I would like to add support for video and audio demux at some point, but don't have the time to develop it right now. Given sufficient user interest or free time, I'll do it. Patches are also welcome in case anyone else wants to help me out, see the contact information below.

METHODS

A subset of the OpenQuicktime API is currently supported. Listed below are the supported methods, details are available at:

  http://www.openquicktime.org/docs/

The methods in the API are prefixed by oqt_. I've dropped the prefix for the Video::OpenQuicktime module. So get_audio_bits() is an internal call to oqt_get_audio_bits().

 get_audio_bits
 get_audio_channels
 get_audio_compressor
 get_audio_length
 get_audio_samplerate
 get_audio_track_count
 get_copyright
 get_info
 get_name
 get_video_compressor
 get_video_depth
 get_video_framerate
 get_video_height
 get_video_length
 get_video_track_count
 get_video_width
