[MPlayer-dev-eng] [MEncoder-users] crash when decode realmedia (MPplayer-1.0rc2)

[pker at 163.com]

I dont know how to report the bug. The following is some GDB output.

Opening video decoder: [realvid] RealVideo decoder
Selected video codec: [rv30] vfm: realvid (Linux RealPlayer 8 RV30 decoder)
==========================================================================
VDec: vo config request - 320 x 240 (preferred colorspace: Planar I420)
VDec: using Planar I420 as output csp (no 0)
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
videocodec: libavcodec (320x240 fourcc=31564c46 [FLV1])
Compiler did not align stack variables. Libavcodec has been miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. You may try recompiling using gcc >= 4.2.
Do not report crashes to FFmpeg developers.
VIDEO CODEC ID: 22
Writing header...
