Adding MP3player Support

[aventae]

Has anyone been able to successfully add in a mp3player/player support to core?

I been tinkering around with it ..just seeing if i can do it.. i did find some example code from codeproject site..but getting stuck trying to make it into a command and show up via gump controls.

/* 
 * 
 * MP3Player class provides basic functionallity for playing mp3 files.
 * Aside from the various methods it implemants events which notify their subscribers for opening files, pausing, etc.
 * This is done for boosting performance on your applications using this class, because instead of checking for info
 * on the player status over a certain time period and loosing performance, you can subscribe for an event and handle it when it fires.
 * This class also doesn't throw exceptions. The error handling is done by an event, because the probable errors which may occur are not
 * severe and the application just needs to be notified for these failures on the fly...
 * Share your source and modify this code to your heart's content, just don't change this section.
 * If you have questions, suggestions or just need to make your oppinion heard my email is krazymir@gmail.com
 * Krasimir kRAZY Kalinov 2006
 * 
 * PS: This source will only work on MS Windows, since it uses the MCI(Media Control Interface) integrated into this OS.
 * Sorry .Gnu and Mono fans! I hope soon to have enough time to get busy working on similar class for these engines...
 *

So you want the core to play music for you? Or...? I don't get what you're trying to do.

pretty much.. cant really do it for players dont think.. unless did some client changes... unless can do like a shoutcast thing via core...

be kinda neat to setup a shoutcast like radio station through core lol...

[Setharnas]

No, actually I think that would be pretty much a waste. If you want something shoutcast like, why not just set it up separately? That way you can put it on another machine, run it only when you want to, make modifications without shutting down RunUO. In contrast, I fail to see any advantages in putting shoutcast into the core.

Main reason is for the learning experience ...I dont nor have i ever went public with my shard that i run on my personal network nor will i start, So yeah this is mainly for learning experience. What i would really like to do is set up a Mp3 player client side that can load winamp playlist or the like. Just to see if it can be done with Uo. But not only would need core modification but client modification as well.. and i really havent learned reverse engineering the client to look to see if it is possible.. pretty sure that it is tho. So atm i am kinda trying to start small .. and grasp the concept of trying to add something in Core hehe.

Hope this explains lil better what i was trying to do... To you Seth aye may seem a waste of time... and maybe it is.. but the learning experience for me.. is worth the time =)

[Setharnas]

Yeah, I can definitely relate to the learning experience thing, no questions there. It's just that I also try to look at things from a practical point of view, and for the reasons already listed in this thread I don't really see this (mostly the client part) as starting small. Sorry if I sounded a bit condescending, that was not what I wanted.

np Seth, aye maybe small wasnt right word hehe.. but seems most ideas i would like to try seems to need some kinda client modification. I had already added successfuly multiple custom map support to the core, but this feature is kinda useless again without client modification. Just trying different things hehe ....

[Setharnas]

In that case, I wish you good luck in your attempts and am eager to see what you get out of the client for a willing community.

thank you... Thought did come to mind on posiblely making this idea work ..but would be begging for the source for PlayUo ..an already modified client =P.. maybe possible to add it to that instead? ... Just a thought and a theory =)
