2018-05-26indeo4: Decode all or nothing of a band header.Michael Niedermayer
This avoids inconsistent value combinations. Alternatively it would be possible to add more checks and careful use of temporary variables, but my try of this quickly seemed to become a rather large change. The disadvantage of this, is that the struct is copied back and forth. Fixes: index 6 out of bounds for type 'const uint16_t [5][16]' Fixes: 6557/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_INDEO4_fuzzer-4787296550256640 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-06-07get_bits: Move BITSTREAM_READER_LE definition before all relevant #includesDiego Biurrun
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.

2013-05-28indeo4: reuse context block VLC for band instead of defaultingKostya Shishkov
Currently if no custom block VLC is specified for band, a default block VLC will be used, while the global block VLC stored in the context should be used instead. This fixes decoding of one sample I have.
2013-05-28indeo4: add missing Haar and slanted transformsKostya Shishkov
That involves fixing INV_HAAR4() macro and changing it to work with different input and output like INV_HAAR8() instead of in-place transform.
