Ticket #5002: libs_libavformat_utils.c-need-to-check-st-codec-again.patch

File libs_libavformat_utils.c-need-to-check-st-codec-again.patch, 993 bytes (added by Erik Hovland <erik@…>, 16 years ago)

adds additional check for st->codec in null check conditional at line 884 in libavformat/utils.c

  • libs/libavformat/utils.c 

    A small change was made in the last version that added some checks for
the internal dvd player. Those checks were good. But one more check
for st->codec before dereferencing is still needed.
