Crash on h264 content

Description

When playing some piece of content on windows using ffmpeg compiled with mingw,
I was sometimes getting a crash while opening the media. The error reported by
windows was: [...] the memory could not be 'read' at [...]. By using libduma,
I've been able to see that it was due to a misaligned buffer.

If 'h264_split' from libavcodec/h264.c returns an odd number, a read error will
be later encountered when the control will reach
'decode_picture_parameter_set()' called by 'try_decode_frame()' when opening the
media.

Using this patch, the problem went away and libduma did not report any more
error when opening the media.

Can you provide us with a sample file that triggers this problem?

comment:3 by i_s_c_y@…, 18 years ago

Yes. Do you have any repository where I could upload it?

Use anonymous FTP to ftp.mplayerhq.hu, dir /MPlayer/incoming

Fixed differently. It is now clean in valgrind.
