2 years agoavformat: prevent triggering request_probe assert in ff_read_packet
Andreas Cadhalpun [Wed, 19 Oct 2016 17:23:49 +0000 (19:23 +0200)]
avformat: prevent triggering request_probe assert in ff_read_packet

If probe_codec is called with pkt == NULL, it sets probe_packets to 0
and request_probe to -1.
However, request_probe can change when calling s->iformat->read_packet
and thus a probe_packets value of 0 doesn't guarantee a request_probe
value of -1.
In that case calling probe_codec again is necessary to prevent
triggering the assert.

div-by-zero in this codepath, such as reported in Mozilla bug #1293996.

Note that this isn't guaranteed to fix the bug, since a compiler is free
to reorder instructions that don't depend on each other. However, it
appears to fix the bug in Firefox, and a similar patch was applied to
libvpx also (see Chrome bug #599899).
