[libannodex-dev] Re: libsndfile w/fishsound support

[Conrad Parker]

ok, here's the latest cut:

    http://www.annodex.net/~conrad/tmp/libsndfile-1.0.9pre3fish4.tar.gz

Changes:
	* applied Erik's patch to merge up
	* implemented read_short, read_int, read_double
	* implemented write_short, write_int, write_double
	* implemented Annodex writing
	* changed SF_FORMAT_ANNODEX to SF_FORMAT_ANX as requested by Erik
	* fixed a bug when decoding Annodex whereby finding the audio
	  duration was not checking the serialno of EOS packets found,
	  so sometimes the granulepos of the CMML EOS packet would be 
	  misinterpreted as the audio duration, leading to truncated
	  decode.
	* add ANX write support to sndfile-convert

It seems to work pretty well, with full encode/decode functionality. I've
been using sndfile-convert instead of oggenc and speexenc (which happen to
be missing on my box) and it works reliably. eg.

	 sndfile-convert -vorbis Goldfrapp-Train.wav Goldfrapp-Train.anx

to encode a wav file as annodexed vorbis.

I've also started hacking up a little remix-based scrubbing program that
for now just does mouse-controlled seeking, which in turn puts sf_seek()
through its paces, and that seems to hold up to some decent abuse on
ogg files (at least until JACK kicks it off ;-) I'll push it a bit harder
before I'm convinced though.

TODO:

	* Expansive test suite, of course.
	* I'm not sure what the preconditions on methods are, so maybe
	  some more NULL parameter checks etc. are required.
	* more SFE_* error reporting back through libsndfile ?

Here's some snapshots of oggz and fishsound from svn:

    http://www.annodex.net/~conrad/tmp/liboggz-0.8.2-k1.tar.gz
    http://www.annodex.net/~conrad/tmp/libfishsound-0.6.0-k1.tar.gz

Enjoy :)

Kfish.
