Thread: Creating a MP3 player in c

I think this is probably a little too hard for you if you aren't sure where to start..... Make sure you're up to the task first.

In general, you need to think about the platforms you want to design this for, the interface, the internal details of what libraries to use, and then how to glue it all together. Much of the work at first has to be all about planning and overview before you get into coding. For the projects you listed, you need to have quite a good handle on C and be proficient enough to handle most of the aspects of the language.

You need to SPLIT your project into smaller modules first. You can start with one of several components, but you should not try to achieve all at once.

You also need to have some sort of plan of how the different components interface from one another. More about that in a bit.

Commonly, we start with the most important component first - to see that we can do the important bit. For example, an MP3 player needs to be able to play MP3 music - otherwise it's pretty much useless. So start by writing some code that can do that - don't bother about a user interface, other than some way to indicate what file you want to play - perhaps even a simple command-line app is the right thing here.

Once you have something you can play MP3's with, you can start on the user-interface for example.

You may also want to have play-lists - so you need to write some code that can arrange a list of MP3 files in the relevant ways. This also means that you (probably) need to save and load playlists from a file that stores this info - how do you do that? Again, it's a separate task, which can be done pretty much independently of the others.

Once you have all the components (and I may not have listed ALL the parts you need - I have never built any form of MP3 player application), then you glue them together.

Interfaces are important. How does the MP3 "play MP3" function recieve the Mp3 from the user interface. How does the user interface know how long the tune is? If you support playlists, how does the interaction of user interface, "play MP3" and play list management talk to each other.
