[Mplayer-advusers] Fw: [MPlayer-users] BUG REPORT: mplayer/mencoder core dump on MOV file from MinoltaDimage 7i camera

[Attila Kinali]

Heyo ppl!

This bug is caused by a too small value of udta_len
in demux_mov.c at line 1448:

(changed stream_read to a non-inline function for debuging)

But udta_len needs to be at least 8 (see call to stream_read)
