Mark Harris	56e2cd9c04	avformat/icodec: Fix crash probing fuzzed file Avoid invalid memory read/crash when frame offset >= 0xfffffff8. Base64-encoded example: AAABADAwMDAwMAAAMAAwMDAw/P///w== (The previous commit verifies that p->buf_size >= 22.) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Mark Harris	1b4fbf8080	avformat/icodec: ico probe with unknown data Fix cases where unknown data (data beyond p->buf_size) could produce a higher ico probe score than if the unknown data was known and valid. For example: Header: OK, 2 frames Frame 0: Unknown (offset points beyond end of probe buffer) Frame 1: Invalid Previously this example had a score of 25, even though the score would be 1 if the unknown frame was known to be valid or 0 if it was known to be invalid. For this example the score is now 1. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	4f0e85517f	avformat/icodec: reduce score returned on probing The ico probe function is pretty weak just checking a few bytes for being 0, 1 or not 0 Fixes probetest failure Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
