Forum topic: thumbnail in custom template
Submitted by jjbarrows on Sat, 2008/08/16 - 06:43.
hi,
i am trying to insert the thumbnail image for video files into a custom template, i just need to know how to extract the file path from the openpackage node, can someone explain how to do this?
thanks,
Joseph
for reference i'm currently using:
<?phpif ($node->type == 'openvideo')
{
$imageUrl = '/files/videos/image-cache/' . $node->field_videofile_0[0]['video_id'] . '_third_130x100.jpeg' ;
}
?>
but this is not enough as it assume the 1/3 thumbnail
There are functions in op_video that do this sort of thing. Try something like
<?php$video = _op_video_get_first_video($node);
echo _op_video_render_preview_image($video, $width, $height, $extra, $image);
?>
$extra is an array of attributes for the img tag.
$image can be 'start' or 'third'.
There should really be a proper API in op_video for this.
Thanks Jonathan,
can $image be 'custom' as well, and how do I pull which is selected from the database ?

Yeah - $image can also be 'custom'.
If you leave off the $image parameter, then the field setting is used.
thanks Jonathan,
I needed just the file path (to pass to a flash movie) so what I have now is:
<?php
if ($node->type == 'openvideo')
{
$op_thumb = "start";
$video = _op_video_get_first_video($node);
$op_thumb_pref = $video['preview_image']['preview_image'];
$height = 100; //manually overriding because am getting 400x300 default
$width = 130; //also this size fits in the flash container
_op_video_render_preview_image($video, $width, $height, $extra, $op_thumb_pref); //i thought calling this would create the right sized jpeg from the png
if ($op_thumb_pref == 'c') { //preview_image type seems to be stored as the first letter only
$imageUrl = '/files/videos/image-cache/' . $node->field_videofile_0[0]['video_id'] . '_custom_' . $width . 'x' . $height . '.jpeg';
} else {
if ($op_thumb_pref == 't') {
$imageUrl = '/files/videos/image-cache/' . $node->field_videofile_0[0]['video_id'] . '_third_' . $width . 'x' . $height . '.jpeg';
} else {
$imageUrl = '/files/videos/image-cache/' . $node->field_videofile_0[0]['video_id'] . '_start_' . $width . 'x' . $height . '.jpeg'; //assume start if all else fails
}
}
?>
this code is in my themes teaser.tpl
does the image-cache get cleaned out every once and a while? because i had this working fine last week but today all the thumbnails are missing, and getting re-generated at 400x300 (thus the changes i've made today to try and force 130x100)
should _op_video_render_preview_image($video, $width, $height, $extra, $op_thumb_pref); create the "image-cache/212_custom_130x100.jpeg" file ?

Try this:
<?php
if ($node->type == 'openvideo')
{
$video = _op_video_get_first_video($node);
// $op_thumb = _op_video_get_preview_image($video);
$op_thumb = "start";
$height = 100; //manually overriding because am getting 400x300 default
$width = 130; //also this size fits in the flash container
$imageUrl = _op_video_render_image($video, $op_thumb, $width, $height);
?>
$op_thumb can be set to the default with _op_video_get_preview_image($video), or you can specify it directly, e.g. 'start'.
Yay!
thanks Jonathan, it's working a treat now
