Michael Niedermayer	7540d60bf6	avformat/dhav: Break out of infinite dhav search loop Fixes: Infinite loop Fixes: 26922/clusterfuzz-testcase-minimized-ffmpeg_dem_DHAV_fuzzer-5794549613723648 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 years ago
Idan Freiberg	a6912e5b88	avformat/dhav: Fix incorrect non-DHAV chunk skipping logic DAV files may contain a variable length padding in between chunks filled with 0xff bytes. The current skipping logic is incorrect as it may skip over DHAV chunks not appearing sequentially in the file. We now look for the 'DHAV' tag using a byte-by-byte search in order to handle such situations. Also the dhav->last_good_pos field will not be updated while skipping unrecognized data.	4 years ago

Anton Khirnov	cea7c19cda	lavf: move AVStream.index_entries to AVStreamInternal Those are private fields, no reason to have them exposed in a public header. Since there are some (semi-)public fields located after these, even though this section is supposed to be private, keep some dummy padding there until the next major bump to preserve ABI compatibility.	4 years ago
