[FFmpeg-devel] double free when encoding in flv

[Frédéric Léger]

Hi all,

we've got some strange problem when using ffmpeg (last svn version) to 
encode as flv :

When trying to encode the file we use this commend line :

ffmpeg -i /home/fred/myvideo.mpg -b 800000 -r 25 -padbottom 0 -padtop 0 
-padleft 16 -padright 16 -ab 128000 -ar 44100 -s 352x288 /tmp/test.flv

And then we encounter the following crash during encoding :
