Hi, VLC recently migrated to libflac 1.3.1, however we had to revert to 1.3.0 as we had crashes for most FLAC files on the Windows desktop platform. More information is available here: https://trac.videolan.org/vlc/ticket/14104 Best, Tristan

Has anyone tried to build flac with the INTEGER_ONLY_LIBRARY flag set lately? I'm getting link errors on IA32 for the SSE optimizations lpc_restore_signal_16_intrin_sse2 and lpc_restore_signal_wide_intrin_sse41. Looks like a define check is missing since the implementation of these functions is only included when not building for integer. I had to exclude them at libFLAC/stream_decoder.c:408 by adding a check for !FLAC__INTEGER_ONLY_LIBRARY. //Joakim -------------...
