Streaming from DAT file

[Michard]

Hi everyone,
I'm currently working on a SFML project. In this project, I'm using a DAT file to store all my files (at the moment only images) to prevent users from modifying them. Now I'd like to store audio data (BGMs and sound effects) in the same file. With Sound effects there shouldn't be any problem, I can just load the data in a char* ecc.. Now I'm facing the problem of BGM streaming. How could I solve my problem? I could just load one whole track at a time, but then I would have a really big size allocated and I wanted to avoid doing so. Any suggestions?

You should not have music and other resources in the same file. sf::Music has an own thread that continously loads stream chunks, and this may create race conditions with other accesses to that file.

Use a separate file for music, and implement your sf::InputStream derivate to read from the .dat file. Make sure you don't play multiple music themes simultaneously, otherwise you have again the problem described above.

Hello Nexus,
first of all , thank you for the help. For the first tip, that's ok, as I don't have any problems with a second dat file. As for the second suggestion, I'm currently using SFML 1.6, while sf::InputStream seems to be included only in SFML 2.0. Any suggestions for version 1.6?

Switch to version 2.0

I don't know to do it with SFML 1.6. But this version has not been maintained for years, contains much more bugs and less features than SFML 2. If it's somehow possible, I really advise you to work with SFML 2.

Thank you anyway, I'll think about switching to 2.0
