* release/0.8: (92 commits) Update for 0.8.13 pngdec/filter: dont access out of array elements at the end aacdec: check channel count vqavideo: check chunk sizes before reading chunks eamad: fix out of array accesses roqvideodec: check dimensions validity qdm2: check array index before use, fix out of array accesses alsdec: check block length huffyuvdec: Skip len==0 cases huffyuvdec: Check init_vlc() return codes. Update changelog for 0.7.7 release mpeg12: do not decode extradata more than once. indeo4/5: check empty tile size in decode_mb_info(). dfa: improve boundary checks in decode_dds1() indeo5dec: Make sure we have had a valid gop header. rv34: error out on size changes with frame threading rtmp: fix buffer overflows in ff_amf_tag_contents() rtmp: fix multiple broken overflow checks Revert "h264: allow cropping to AVCodecContext.width/height" h264: check ref_count validity for num_ref_idx_active_override_flag ...
