MP4: add offset of moov atom to MP4Info #80

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When using HTTP to (pseudo-)stream MP4 files, it is important that the moov 
atom is at the beginning of the file, and not at the end (otherwise the player 
must download the whole file before it can be played).

It would be very helpful if mutagen could be used to find out whether the moov 
position is correct or not. Fortunately that info is already available, it is 
just not stored.

The attached patch adds a new value moov_offset to MP4Info, so that it can be 
retrieved by the caller.

Please include some comment explaining why the moov offset is provided, and 
include a test case. (It can probably be worked into one of the existing suites 
easily.)

When writing new tags to an MP4, is there currently any way to specify to put 
the moov atom at the beginning?
