I want to use FMOD to open a stream and play/listen to it, which is pretty easy to do with FMOD. I would also like at the same time to write the stream I am playing to disk as an MP3 file. I can parse the SHOUTCAST headers and open a TCP/IP connection and write the stream on my own but I’d like to do it using FMOD if possible, any suggestions on how to do this?

After looking at cddarip, netstream and the lame_enc, bladeenc examples I can now play and save a SHOUTCAST stream. When I play it back with Realplay there is a 2-3 second lag before it starts playing, how can I fix this?
BTW FMOD is amazing it was really easy to do.
I looked at a hexdump of the MP3 file I wrote and it had a lot of empty blocks before the data started. I figured that because of my firewall kicking in each time, it was delaying the stream while the DSP callback was still being called and calling lame_enc. I re-configured the firewall and it was still delaying about a second and writing about 70 empty frames. Anway I just moved the code for creating the DSP callback and there is no delay at all.
Are you trying to save a SHOUTcast stream to disk as an mp3 or are you trying to rebroadcast it?
If you’re trying to rebroadcast it then you can’t do it directly with FMOD – we do playback only, not broadcasting, so you’ll have to do all the SHOUTcast/network broadcasting stuff yourself.
If you’re just trying to save it to disk then have a look at the cddarip example and modify it to pass chunks of data to BladeEnc.dll or lame_enc.dll rather than just using fwrite.
I only want to write the stream to disk while playing it. I couldn’t find cddarip example until I realized I didn’t have the newest version of fmodapi. I downloaded it and looked at cddarip and I checked out bladeenc.dll and lame_enc.dll too. Looks like a good solution for me… thanks.
