When I was trying to find yesterday's xmms-plugin bug, i have noticed that seeking in stream without seek-table isn't very good. With attached patch it is much better. -- Miroslav Lichvar -------------- next part -------------- --- src/libFLAC/seekable_stream_decoder.c.orig 2003-02-26 19:41:51.000000000 +0100 +++ src/libFLAC/seekable_stream_decoder.c 2003-07-09 23:49:35.000000000 +0200

Hi, This patch improves compression a very tiny bit on average, but up to 0.1 percentage point for classical music. I haven't found any tracks that show worsening compression with this patch. -------------- next part -------------- A non-text attachment was scrubbed...

...ven't was already dropped support for > MSVC6? If so, we should drop this #ifdef hackery. Can test this without > the hackery for versions of MSVC > 6? I don't have VC 2002/2003, but the oldest Visual Studio that FLAC supports is MSVS 2005 anyway. It can compile FLAC__uint64 -> FLAC__double conversion without intermediate FLAC__int64. So this "spoon feed" isn't necessary. (found another place with this double conversion, inside src/utils/flactimer/main.cpp. It also has unnecessary #defines for int64_t/uint64_t)
