looking for help creating a mime type

[kendell clark]

hi all
After a lot of digging through my cd collection, I came across an
audible audio file I had backed up who knows how long ago. I've been
wanting to create fully functioning mime types for this and it's
enhanced audio counterpart for a while now. I'm a complete novice at
this, so I'm looking for any willing helpers. I can upload the files
somewhere so if anyone decides to help me they can have access to them.
Note that these are legal files, legally obtained from audible with an
active account, mine. Well, not active anymore, but it was when these
files were obtained. These seem to be mp3 files with some strange stuff
at the beginning, because simply renaming the file extension doesn't
allow them to be played, but I can easily convert them with ffmpeg. Any
help would be greatly appreciated.
Thanks

Your first step will be figuring out if there is any existing media
type for this type of file.

Looking at http://www.digitalpreservation.gov/formats/fdd/fdd000103.shtml#sign
I see audio/audible
audio/x-pn-audibleaudio, the latter which looks like it could be used in xdg.

After that you'll want to file a bug on the freedesktop bugzilla
(https://bugs.freedesktop.org/), and provide a patch if possible.
There's other mime type requests on that bugzilla you can take example
on.

hi
Thank you very much for that link. I now have some of the bits I need to
create a fully functioning mime type. The one thing I'm missing is a way
of uniquely identifying audible audio files without relying on the file
extension. If I can't find this, creating a mime type will be pretty
easy, but I'd prefer to be able to uniquely identify the file type if
possible. It's amusing. The audible website swears that you can't
convert their files into other formats, and yet I did so via ffmpeg.
What else should I do? I can't seem to find an accessible hex editor, so
if anyone is willing to help me out there by getting some form of magic
info, integer, string, etc that I can use to single out the audible
format I'd really appreciate it. Don't worry, I'm not asking anyone to
do all the work for me, I'm still going to file the bug and make sure
everything complies with the mime spec.
Thanks

You can use the command line hex editor you probably already have
installed. hexdump -C file.aa | less. There's plenty of gui ones too.

A magic number isn't required (nor even necessarily available), the
.aa extension isn't used by anything else I believe so you could just
use that.

hi
I'll try to get some form of unique identifier, but if I can't find one,
I'll file a bug. Should I include an override.xml file generated with
mime-editor? It's the only way I know of to make mimetypes. Would adding
support for this via gstreamer be possible? I'd like to eventually be
able to play these files with anything that can play through gstreamer,
and also to use gui converters to convert to different formats. This is
the wrong list for this, I'm only trying to understand what's required
to add codecs to gstreamer. I believe audible audio files are just
containers, they're not audio files themselves. They're a wrapper with
different format audio in them, usually mpeg layor 3 heavily compressed.

hi
Ok, the bug has been filed at:
https://bugs.freedesktop.org/show_bug.cgi?id=94889. This provides
support for the audible audio format, but purely based on the file
extension. Next is to get support for this put into gstreamer. Where
should I start for that? I'm no programmer, but since the audible file
is a container with other audio inside of it it shouldn't be too hard.
Usually mp3, but occasionally the acelp or sony's HAC ((hearing aid
compatible) codecs are used, although I don't have any idea what those
last two are.
Thanks

hi
I've filed the bug already. I seem to be stuck though. I've found the
magic number that uniquely identifies an audible audio file in the
ffmpeg source code at libavformat/aadec.c. The problem is, I can't
locate that number in the file anywhere to put it in mime editor. I
think I might need a little help. I want to generate a test.aa file,
which I thought about doing by copying a valid audio book and just
deleting the audio out of it, but I'm not sure how to do that either.
Please bear with me, I'm still new at all of this. I've already cloned
the shared mime info github repository, and I've read the hacking file,
but the last step, giving a unique string or integer is the part I'm
having trouble with. I did find a hex editor I can use, hexdump.I've run
the following command: hexdump --C test.aa > temp, but I'm not sure what
I'm looking for in that file. I've looked at all of the test cases in
tests, but how were those generated?
Thanks

hi
Sending this to the list since I've apparently been sending to one
particular person this whole time and not knowing it.

For those of you who don't know, I'm trying to create a fully
functioning mime type, complete with magic number for audible audio and
enhanced audible audio files. I've got the magic number for audible
audio files from the ffmpeg source code and ... well, I'll just let you
guys read the message below.

Sorry for top posting, I know some mailing lists prefer in line quotes,
and I'll try my best to stick to that after this message.
Thanks
