I can confirm this issue. I have Debian Sid and apache segfaults when
i call ffmpeg_frame->toGDImage().

Here is a part of backtrace:

I'm unable to reproduce the error, could you please provide a complete
backtrace and more details about the test conditions? You can find
instructions to generate the backtrace at:

Thanks for your reply.

During this time i changed the code many times. Now i'm using
console ffmpeg via shell_exec function because it is easier and faster
then php ffmpeg to gd.

Subject: php5-ffmpeg: Segfault when using toGDImage

Hello,

yesterday we have encountered exacly the same problem. We found that using
php5-ffmpeg from debian build segfaults in toGDImage. while googleing we derived
 this workaround, which is basically only rebuild of debian sources, with minor
change in source code, probably due to name refactoring of some constat


cd /tmp
rm -fr ffmpeg*
aptitude purge php5-ffmpeg
apt-get source php5-ffmpeg
rm -rf ffmpeg-php-0.6.0/
dpkg-source -x ffmpeg-php_0.6.0-2.dsc
cd ffmpeg-php-0.6.0
#http://ubuntuforums.org/showpost.php?p=7022607&postcount=8
vi ffmpeg_frame.c
 :%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
 :w
 :q!
dpkg-buildpackage
cd ..



but anyway, we were unable to build pure debian sources, without that vi fix ;((

anycase, crashing could be somehow related to ffmpeg itself or dynamic linking,
because we'r not using squeezes builds but other builds with mp3 codec enabled from:

 deb http://www.debian-multimedia.org squeeze main non-free

Also we can provide you with our test case ...

Best regards
Radoslav Bodo
