Andreas Cadhalpun	946ecd19ea	smacker: limit recursion depth of smacker_decode_bigtree This fixes segmentation faults due to stack-overflow caused by too deep recursion. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	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
