I'm running the following script on a RH Linux 3ES machine with no
problems, however when moving the script to a FreeBSD machine I get this
error:
[21-Mar-2005 10:58:00] PHP Warning: togdimage(): supplied resource is
not a valid Image resource in /usr/local/www/data-dist/ffmpeg/bar.php on
line 16
Here is the script I'm testing with:
<?php
header("Content-type: image/jpeg");
$file = "qt/video.mov";
$movie = new ffmpeg_movie($file);
$total = $movie->getFrameCount();
$bitrate = $movie->getBitRate();
$type = $movie->getVideoCodec();
$id = round($total/2);
$frame = $movie->getFrame($id);
$width = $frame->getWidth($frame);
$height = $frame->getHeight($frame);
$image = $frame->togdimage();
imagejpeg($image,'',100);
?>
The only underlying difference is the OS. Both machines run PHP
4.3.10, ffmpeg 0.4.9p1, and ffmpeg-php 0.4.3, and in both cases
ffmpeg-php is built as a dynamic extension. An interesting thing to
note is that on the troublesome BSD machine, all the other functions
seem to work. It correctly gets the frame count, bit rate, video codec,
width and height.

I assume you're using the same version of libavcodec and/or libavformat
since you're using ffmpeg 0.4.9p1 on both machines.
One thing I could think of is that your video.mov has it's headers
compressed with zlib. Make sure that ffmpeg is compiled with zlib support.
Could you give us a link to the file you tested with (video.mov) ?

Yes indeed, the same version of libavcodec on both boxes. I double checked the config on the FreeBSD machine and it does have zlib support enabled, I'll include the configure output.

Hi Scott,
togdimage() is the only function that interacts with gd so it's likely a
problem with the gd/ffmpeg-php integration (which is pure voodoo thanks
to the way gd is bundled into the php sources). Which version of gd are
you using? Is gd built into php or as an extension?
BTW: I work at a large media company in Burbank and know some folks who
might be interested in WiredrivePro/Hub. Are these apps web based?

The version of GD in use is the bundled version in PHP, 2.0.28, and
currently it's being loaded as an extension. It should be fairly
trivial for me to modify the port and build it directly into PHP and
give that a try.
Wiredrive Pro and Hub are web based apps, we just rolled out
version 1.8 a couple months back with 2.0 currently in the works. If
the people you know want to talk to someone in depth about it have them
give a call to the number in my sig and ask for either Bill Sewell or
Erika Levy, and access to the demo system can be set up.

A follow-up on building GD directly into PHP rather than as an extension: the bar.php script I posted earlier causes the Apache process handling the request to segfault. It would seem that PHP/GD doesn't play nicely on BSD. -- Scott Larson Network Administrator IOWA LLC T:310.823.8238 F:310.823.7108 E: su...@io... www.iowalab.com |

Try running the script from the command line? You may get a more useful
error report.
php bar.php
If it still segfaults, run it in a debugger...
gdb ---args php bar.php
...and type 'bt' after the segfault to generate a stack trace.
Thanks,

Well I've managed to get this working. The major problems were avcodec.h trying to #include <ffmpeg/common.h> and some strangeness with gd/zlib being loaded as modules. After fixing the include (which seems to not be a problem in the latest cvs), and statically building in gd & zlib then all the problems went away and the script has access to togdimage(); On Thu, 2005-03-24 at 18:55 -0800, Todd.Kirby wrote: > Scott Larson wrote: > > > A follow-up on building GD directly into PHP rather than as an > >extension: the bar.php script I posted earlier causes the Apache process > >handling the request to segfault.
