[LAD] jack ringbuffer usage
Hi,
I'm trying to use jack's ringbuffer like this:
- initialization:
jack_ringbuffer_t * ringBuf =
jack_ringbuffer_create(sizeof(jack_default_audio_sample_t) * (116));
memset (ringBuf-buf, 0, ringBuf-size) ;
- jack process callback:
jack_default_audio_sample_t buf[numChannels];
size_t read_cnt = 0;
for (_frameCounter=0; _frameCounter nFrames; _frameCounter++) {
read_cnt = jack_ringbuffer_read(ringBuf, (void*)buf, sample_size *
numChannels);
^ error
}
but g++ won't compile the code and report this
error: invalid conversion from 'void*' to 'char*' [-fpermissive]
/usr/local/include/jack/ringbuffer.h:136: error: initializing argument 2 of 'size_t
jack_ringbuffer_read(jack_ringbuffer_t*, char*, size_t)' [-fpermissive]
passing -fpermissive gets the program running but is it the right way to do it?
Thanks

Raphaël.

How do you control the decks? mouse, key shortcuts, other? You select a file and press play. You could also press F9 .. F12 to start/stop the decks. Or you own a studio surface which sends joystick button press/release events. If you have a USB joystick, simply connect it. Press Button 1, and it plays deck 1, release button 1, and it stops. Of course, you can also press Buttons 1-4 simultaneously to have all four decks playing at the same time. ;) Selecting a new file while one is playing queues the new file. Press stop or wait for the current one to finish to actually play it. (it's a safety for radio stations, so they're not accidentally stopping the current playback). Same for stop: program only quits if you stop all four decks and then press Ctrl+q. Well, the window-close button is a shortcut, but it wouldn't be visible in fullscreen mode.
