Michael Niedermayer	c188f358aa	avcodec/wavpack: Treat the first block coding too many channels as an error Fixes memleak Fixes: 236/8aeebc9ca49b91bf71c114dcefac56c154a3a563 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Diego Biurrun	b668662939	get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes This avoids the danger that get_bits.h might get indirectly #included before BITSTREAM_READER_LE is defined. Also sort headers into canonical order where appropriate.	9 years ago

Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions.

Andreas Cadhalpun	d0eff8857c	wavpack: limit extra_bits to 32 and use get_bits_long More than 32 bits can't be stored in an integer and get_bits should not be used with more than 25 bits.

Anton Khirnov	7d039e70a5	wavpack: extract channel information from the bitstream This way we don't require the caller to parse the block header. It also allows the channel configuration to change mid-stream.	12 years ago

Anton Khirnov	9b6f47c448	matroskadec: export full wavpack blocks. This allows us to get rid of demuxer-specific hacks in the decoder and will allow streamcopy from matroska once we have a wavpack muxer.	12 years ago
Anton Khirnov	5074f4545c	wavpack demuxer: export full wavpack blocks. Currently the demuxer shaves the blocks and exports only the information that is useful to the decoder. Exporting the blocks just as they are stored is simpler to understand and will make remuxing wavpack easier.	12 years ago

Anton Khirnov	1d177200ce	wavpack: remove a useless check. Number of samples in the first block is checked to be strictly positive earlier in wavpack_decode_frame() and number of samples in all the other blocks is checked to be equal to the first one.	12 years ago
