2020-02-11avformat: Remove unnecessary av_packet_unref()Andreas Rheinhardt
Since bae8844e the packet will always be unreferenced when a demuxer returns an error, so that a lot of calls to av_packet_unref() in lots of demuxers are now redundant and can be removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Marton Balint <cus@passwd.hu>

2016-11-11icodec: correctly check avio_read return valueAndreas Cadhalpun
It can read less than the requested amount, in which case buf contains uninitialized data, causing problems like segmentation faults later on. Also make sure that image->size is positive, so that it can't match a negative error code.

2016-02-20avformat/icodec: Fix crash probing fuzzed fileMark Harris
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>
2016-02-20avformat/icodec: ico probe with unknown dataMark Harris
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>
