Muzu.TV helps the SRAchart

Muzu.tv – With This Weeks Chart

After a London Meeting with Muzu.TV, the Student Radio Chart, which I co-ordinate for the Student Radio Association and Stations around the country we now output some chart data via their video Service.

I just compiled this weeks, have a watch….

Check the channel on Muzu.tv and follow the SRAChart on Twitter @SRAchart, finally tune in each week from 3pm on a Sunday!

Marriage of Figaro

Opera!

Will be posting photos later this week of some lighting I have designed for Opera Soc’s Performance of Marriage of Figaro.

Opening night is tomorrow night in the Riley Smith Hall at Leeds University Union, on until Saturday!

If you’re about about and fancy a opera come on down!

In terms of Tech. I’ve got standard generics, tarts, cans and Source4 Jr’s. Plus a load of Parnells with Scrollers on. All running off Zero88’s Bull Frog lighting desk.

Motion Graphics

Upcoming on this Blog: Motion Graphics, ala Degree Coursework.

Part of my degree is to create a 3-4 minute project, using Adobe After Effects.

So this is the first of many blog entries on the Subject. This blog (under this category) will form part of my project entry, (5% in fact), as a production journal.
So any comments will come in handy!

Currently I’m slightly add odds, but have a thought of creating a advert for Firefox or perhaps google chrome.

Ultimately using shape and colour manipulation to merge the relevant browser logos to create the chrome one.

Perhaps starting the 3-4 mins with a quick browser history, Netscape anyone??? 😛

Watched Transformers (the first Michael Bay one) today and having watched Start Trek XI by J.J. Abrams, should be good inspiration for this project, in terms of technology.

Avatar might be a bit far…..

Javascript Image.onLoad Broken

A Javascript Problem, and a Solution

Heres my code:

        var target = '';
        var loadstr = '';
        var webcamimg = '';

        function runwebcam(ttarget) {
                target = ttarget;
                webcamimg = new Image();
                loadstr = "http://lsrfm.com/images/webcam/lsr_studio.jpg?" + Math.random();
                webcamimg.src = loadstr;
                webcamimg.onLoad = gowebcam();
        }

        function gowebcam() {
                //stuff
        }

Thru the use of FireBug I’ve discovered that the function onLoad declared by onLoad is executing regardless of whether the image has finished being downloaded, which was my understanding as per TechRepublics Article.

So after a bit of hunting around I found this from Talideon.com.

So my adjusted code now reads:

        function runwebcam(ttarget) {
                target = ttarget;
                webcamimg = new Image();
                loadstr = "http://lsrfm.com/images/webcam/lsr_studio.jpg?" + Math.random();
                webcamimg.src = loadstr;
                webcamimg.onLoad = gowebcam();
        }
        function gowebcam() {
                if (!webcamimg.complete) {
                        setTimeout("gowebcam()", 500);
                        return;
                }
                //stuff
        }

Curl, MusicBrainz and PHP

A quick block of PHP to fetch MusicBrainz ID for a song and artist based on Song Data.

As part of the New Years Resolutions I didn’t make.

I’m updating my blog with some Code Snippets!

Been fiddling about with my PHP powered Jukebox that plays out on LSRfm.com (Leeds Student Radio) Overnight, and there is a need for a bulk track adder.

So, I’ve been tidying up the MusicBrainz Data Fetcher, as well as fiddling with PHP and getting ID3 tags from Files. But thats a different blog post.

Essentially there is a (new-ish non updated recently) PHP Library for the interaction with MusicBrainz, (A music database), recently found that (this morning its rubbish), but of no good.

So went back to my curl method.

Tidyied it up and got it down to a few less lines.

Essentially for a given track, the PHP extracts the ID3 tags, and then passes it to this function: (its needs making into a function btw :-P)

$curl = new curl();

$data = array(
	'title'		=> 'Showdown',
	'artist'	=> 'Pendulum',
	'release'	=> 'In Silico',
	'duration'	=> 327784,
//	'tracknumber'	=> 0,
//	'count'		=> 10,
//	'releasetype'	=> '',

	'limit'		=> 25,
	'limit'		=> 1,
);
$target = 'http://musicbrainz.org/ws/1/track/?type=xml';
foreach ($data as $ref => $dat) {
	$target .= '&' . $ref . '=' . urlencode($dat);
}

                                $curl->target($target);
                                $curl->runit();
                                $mb = $curl->bodyarray['metadata'];

if (isset($mb['track-list'])) {
	$mb = $mb['track-list'];

	if (isset($mb['track']['0'])) {
		$mb = $mb['track'];
		$artist_id = $mb['0']['artist_attr']['id'];
		$song_id = $mb['0_attr']['id'];
	} else {
		$artist_id = $mb['track']['artist_attr']['id'];
		$song_id = $mb['track_attr']['id'];
	}
} else {
	// no data
}

echo "\n" . $artist_id . ' ' . $song_id;

Where new curl() just calls my Curl Class.

I’m sure you have your own ways of doing curl, but mine just sets the target with $curl->target and curlexec() with $curl->runit.

The result is in $curl->body, or exploded nicely as an array in $curl->bodyarray. I’ll post about my curl later! As well as some other Carlyon_CMS stuff.

So thats a quick rough and ready way to get a artist and song ID from MusicBraiz.

Its worth noting that since my limit is st to 1.

The first option of if (isset($mb[‘track’][‘0’]) is entirely redundant, as that only triggers when mb returns more than 1 result.

(I only just added limit before writing this post, which is where I decided to write this post)
