qtfaststart 1.8

Description:

qtfaststart 1.8

Quicktime/MP4 Fast Start
Enable streaming and pseudo-streaming of Quicktime and MP4 files by
moving metadata and offset information to the front of the file.
This program is based on qt-faststart.c from the ffmpeg project, which is
released into the public domain, as well as ISO 14496-12:2005 (the official
spec for MP4), which can be obtained from the ISO or found online.
The goals of this project are to run anywhere without compilation (in
particular, many Windows and Mac OS X users have trouble getting
qt-faststart.c compiled), to run about as fast as the C version, to be more
user friendly, and to use less actual lines of code doing so.


Features


Works everywhere Python (2.6+) can be installed
Handles both 32-bit (stco) and 64-bit (co64) atoms
Handles any file where the mdat atom is before the moov atom
Preserves the order of other atoms
Can replace the original file (if given no output file)




Installing from PyPi
To install from PyPi, you may use easy_install or pip:
easy_install qtfaststart


Installing from source
Download a copy of the source, cd into the top-level
qtfaststart directory, and run:
python setup.py install
If you are installing to your system Python (instead of a virtualenv), you
may need root access (via sudo or su).


Usage
See qtfaststart --help for more info! If outfile is not present then
the infile is overwritten:
$ qtfaststart infile [outfile]
To run without installing you can use:
$ bin/qtfaststart infile [outfile]
To see a list of top-level atoms and their order in the file:
$ bin/qtfaststart --list infile
If on Windows, the qtfaststart script will not execute, so use:
> python -m qtfaststart ...


History


2013-08-07: Copy input file permissions to output file.
2013-08-06: Fix a bug producing 8kb mdat output.
2013-07-05: Introduced Python 3 support.
2013-07-05: Added launcher via ‘python -m qtfaststart’.
2013-07-05: Internal refactoring for clarity and robustness. Functions
now work with named tuples. Backward compatability is maintained. Expect
a future, backward-incompatible release to replace other functions.
2013-07-05: Created an Atom namedtuple to represent a fourcc atom
(name, stream position, and size).
2013-01-28: Support strange zero-name, zero-length atoms, re-license
under the MIT license, version bump to 1.7
2011-11-01: Fix long-standing os.SEEK_CUR bug, version bump to 1.6
2011-10-11: Packaged and published to PyPi by Greg Taylor
<gtaylor AT duointeractive DOT com>, version bump to 1.5.
2010-02-21: Add support for final mdat atom with zero size, patch by
Dmitry Simakov <basilio AT j-vista DOT ru>, version bump to 1.4.
2009-11-05: Added –sample option. Version bump to 1.3
2009-03-13: Update to be more library-friendly by using logging module,
rename fast_start => process, version bump to 1.2
2008-10-04: Bug fixes, support multiple atoms of the same type,
version bump to 1.1
