...tream is subset and "false" if stream is not "subset". What parameters need to test/check for subset compliance? If one or more of the following statements is true the stream is NOT subset. sample size in bits = not (8 or 12 or 16 or 20 or 24) or min_partition_order > 8 or max_partition_order > 8 or min_prediction_order > 12 and samplerate <= 48000 or max_prediction_order > 12 and samplerate <= 48000 or frame_size > 4608 and samplerate <= 48000 or frame_size > 16384 Thanks in advance!

Problems in FLAC 0.9: - On alpha, flac immediately dumps core for both encoding and decoding (FreeBSD/alpha). - The distribution Makefile.in files haven't been generated with "automake --include-deps". The resulting Makefiles aren't fully portable; in particular they break with BSD make. In the future, care should be taken to use "--include-deps". - What is
