I modified my vanilla multicast transmitter to send MP3 frame-by-frame. My test file has a constant frame size of 1044, which I add a 16 byte header to for a total payload of 1060 bytes per UDP packet. The play duration of a frame is about 26 ms. The transmitter has no trouble keeping up. I will be building the MP3 receiver next. If I can get it working with 2 devices on a table top, I guess the next step will be testing in more realistic circumstances. Do you think it has a good chance of working, or should I really be using OpenPGM ? Is there any difference between plain old OpenPGM and the version included in ZeroMQ ? Does the plain OpenPGM run on android ? Is there a JAVA binding for it ?
