PHP based torrent file creator, tracker and seed server – PHPTracker

September 16th, 2011 Comments off

Great software!

Why PHPTracker? Because it’s not “just a tracker”, it contains a seeder server too so the distribution of your files is automatic. This is a big step for the content providers to adapt this amazing technology and change the stereotype that “torrent = warez”.

ffmpeg-php – error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)

August 24th, 2011 Comments off

ffmpeg-php – error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function) | HOW GEEK!.

/root/install/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function 'zim_ffmpeg_frame_toGDImage':
/root/install/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: 'PIX_FMT_RGBA32' undeclared (first use in this function)
/root/install/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: (Each undeclared identifier is reported only once
/root/install/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: for each function it appears in.)

/root/install/ffmpeg-php-0.6.0/ffmpeg_frame.c:421: error: 'PIX_FMT_RGBA32' undeclared (first use in this function)
make: *** [ffmpeg_frame.lo] Error 1

To fix this, replace PIX_FMT_RGBA32 with PIX_FMT_RGB32 .

You can use “rpl” to replace files recursively:

cd to the ffmpeg-php folder and run this command (beware!):

rpl -R PIX_FMT_RGBA32 PIX_FMT_RGB32 *

If rpl not installed on your system, install it, for example:

yum install rpl

Smarty parse a string as template

October 16th, 2009 Comments off

It’s the best way to parse a string as Smarty template. You need to follow only 3 steps!

First of all we need to register a new template resource – string.

$smarty->register_resource("string", array("string_get_template",
 "string_get_timestamp",
 "string_get_secure",
 "string_get_trusted"));

Then add function implementations

function string_get_template ($tpl_name, &$tpl_source, &$smarty_obj) {
    global $smartyStringTemplates;
    $tpl_source = $smartyStringTemplates[$tpl_name];
    return true;
}

function string_get_timestamp($tpl_name, &$tpl_timestamp, &$smarty_obj) {
    // do database call here to populate $tpl_timestamp.
    $tpl_timestamp = time;
    return true;
}

function string_get_secure($tpl_name, &$smarty_obj) {
    // assume all templates are secure
    return true;
}

function string_get_trusted($tpl_name, &$smarty_obj) {
    // not used for templates
}

And the last step. Create an array of string templates and parse a string by passing it’s index in array

$smartyStringTemplates = array('{php}date(){/php}', '{$helloWold}');

print $smarty->fetch("string:1"); // will fetch a string {$helloWold}
