M4AMetaData now passes all the old and updated unit tests, save one. The iTunes-encoded M4A still doesn't generate the correct amount of samples when rewritten. I'm almost certain this is a matter of it needing '----' atoms from the original file when setting metadata. But now that those are being read/written correctly during round-trips, these should be easy to port (analagous to how FLAC's STREAMINFO is ported when metadata is rewritten). eac84bb039bcedca77e93c3124106c8ac7ccac0f Brian Langenberger bjl@usa.net 305c90e4fce254278753017bb552557cb83948ef Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/56ab801804c26508761c8ba830edfb71659a0346 56ab801804c26508761c8ba830edfb71659a0346

Preliminary redesign of M4AMetaData object. It's essentially the contents of the ILST atom, which is a container for __ILST_Atom__ objects (which, themselves, are atom containers). Modifications to M4AMetaData will then be transferred directly to the sub and sub-sub-atoms. set_metadata() will then rebuild the META atom. Thus, M4AMetaData will likely no longer act as a dict and some tests will need readjusting, but it should be improved overall. e083327fb24269017b323d139b5042a14b185697 Brian Langenberger bjl@usa.net e372f0c0bc33f53bc82d6323a9076e026ecc2160 Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/e42d7aa5ceaaa9abb62218552047c7df9fd6a4db e42d7aa5ceaaa9abb62218552047c7df9fd6a4db

Further refinements on the META and ILST atom Constructs.

Tweak META atom rewriting to be less destructive. In addition, ILST's sub-atoms should be saved internally much closer to their actual representation.

Minor debugging tweaks to help in M4A metadata handling. iTunes-generated M4As still aren't being tagged properly. It seems as if the first frame's worth of samples is being lost even though the STCO atom is being set correctly and the MDAT atom is unchanged. It's a tough nut to crack since there's so few other changes. I used to believe M4A's scheme of handling metadata in the same chunking method as its main data was a fairly clever scheme that reuses file parsing code (in contrast to something like FLAC, in which metadata handling is very different from frame handling). But in reality, this intermixing data and metadata makes M4As extremely fragile. Thus, one misstep in metadata handling can render the entire file unplayable. 3dc62f2aec60b148866d0caaa05bfcfc5e061d97 Brian Langenberger bjl@usa.net f379a849290020d075a7c537fcfe0eadf53c4c80 Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/12bac5fcf265768ef01526375ec64b078be430de 12bac5fcf265768ef01526375ec64b078be430de

Preliminary M4A tests in place. Though adding actual M4A files to the test suite will bloat the source, this is the only really good way to test them properly. 5eb71776c04a72bf6e1e81c2b94a49787c317dd5 Brian Langenberger bjl@usa.net 83e19d384c08b6779ee9180ea3d90ad45717f0eb Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/f379a849290020d075a7c537fcfe0eadf53c4c80 f379a849290020d075a7c537fcfe0eadf53c4c80

2009-06-20T13:03:23-07:00

Critical M4A metadata tagging fix. STCO offset lists start from what's probably the first AAC sync frame. In Nero-generated files, that's always 0x10 bytes from the top of the MDAT atom. In iTunes-generated files, it's only 0x08 bytes from the top. set_metadata() now looks for the first 0x21 byte, which is probably a sync signature of some sort. 43c7302e5dcd4787246968aa884b49e8c7063b0e Brian Langenberger bjl@usa.net 564a8b75c3d3e03e41c938cff5bb3fdcce83c15f Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/83e19d384c08b6779ee9180ea3d90ad45717f0eb 83e19d384c08b6779ee9180ea3d90ad45717f0eb
