Hi guys-- I'm fairly sure that selling a game written with Allegro is legal, and yes, I would chip in back to the community should I make any cash from my efforts... ...however, what about if I use the Allegromp3 code in there as well -- is that legal? Anyone got any experience?! Dan |

Have you read it's license? It should be written there __________ |

You'll need to pay a royalty to use the MP3 format. I would suggest using Ogg Vorbis. There are a couple libraries that allow this with allegro, and you wont need to pay royalties to use the Ogg Vorbis file format. Look into alogg. "He who controls the stuffing controls the Universe" |

The license was long and wordy, and I am most definitely not a lawyer...! I got confused about what I can and can't do...! Alogg sounds good, I'll look into it. Ta. EDIT: Just thinking, actually... if I can't use .mp3s because the format is copyrighted, that means I can't invite users to put their own .mp3 tracks in a folder and stream those in-game, doesn't it? Which means I'll have to use another format like .ogg Here's my next questions: is it bad practice/ a major drain to simply use Allegro's SAMPLE code for music? This "register_sample_file_type" function looks exciting... does that work? Sorry -- this should most likely be in the Programming Forum now, shouldn't it?! |

Why wouldn't register_sample_file_type work? AFAIK it works fine. And whats wrong with using allegro SAMPLEs for music? |

Royalties are needed if you distribute the file, but the decoder is perfectly legal to distribute. If you wanted you could distribute with ogg and allow them to be replaced with mp3's.. or just allow mp3's through some other means. "He who controls the stuffing controls the Universe" |

I was hoping register_sample_file_type would work for music... just wasn't sure...! Will give it a bash this weekend... Could I use it to pick up on .mp3s in a /music folder, convert and play them? d |

Quote: Why wouldn't register_sample_file_type work? AFAIK it works fine. And whats wrong with using allegro SAMPLEs for music? Well, uh... you could. What you'd end up with is essentially a module-style implementation where you slice your song into small snippets and lace them together as needed. If done properly you could save some space in memory, but you'd automatically lose the benefit of compression. There are ways around that... So, why not simplify things and look into a module format like XM or IT? You could use the DUMB library to play them --> |

Music tends to be a few minutes in length. Uncompressed in a SAMPLE struct, that would be: -- |

Does that mean you can distribute .oggs along with a ogg-to-mp3 converter in a game which only supports .mp3's for free? ---------- |

No. Since an OGG->MP3 recoder is also an MP3 encoder, you cannot distribute it freely. An MP3->OGG recoder would be fine, though. --- |
