RE: [Ffmpeg-php-user] togdimage() not working on BSD

[Rob C. <ro...@ma...>]

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) ?

Subject: [Ffmpeg-php-user] togdimage() not working on BSD

     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.
