Hi all, Sorry for bringing this up this short before the release, but I noticed something rather strange.
I was doing some more exotic checks on the last pre-release when I tried test_streams.sh with FLAC 1.3.0 encoding and an older version (1.1.0 or something like that) decoding. This failed for 24-bit samples and I wondered why. After quite some tests and hex-editors, I found out this is because older decoders do not support the RICE2 partition. This was added with FLAC 1.2.0, but it's not in the changelog. I found this e-mail on the list which I think is related: http://lists.xiph.org/pipermail/flac-dev/2007-April/002179.html It looks like RICE2 was implemented in the decoder just before the release of 1.2.0. (See http://flac.cvs.sourceforge.net/viewvc/flac/flac/src/libFLAC/stream_decoder.c?view=log revision 1.138 and the 1.2.0 release tarball) I don't know why this isn't on the changelog, but it is probably still a good idea to add it. This only breaks compatibility for 24-bit streams. (So: decoders older than 1.2.0 might not be able to decode 24-bit FLAC files made by libFLAC 1.2.0 or newer) Oh, and for the record, if I disable all 24-bit tests, it works fine: flac-1.1.0 is able to to decode streams encoded by flac-1.3.0pre4 working through test_streams.sh :) _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
