A CD-ROM device is inferred from a mounted cdfs volume, so device 0 is - not necessarily the first CD-ROM device on the system. (Somewhat easy to fix - by useing the device name from the volume id's to reorder the volumes) - - 2. You can only open and control 1 CD-ROM device at a time. (Challenging to fix, - due to extensive code restructuring) - - 3. The status reported by SDL_CDStatus only changes to from CD_PLAYING to CD_STOPPED in - 1-second intervals (because the audio is buffered in 1-second chunks) If - the audio data is less than 1 second, the remainder is filled with silence. - - If you need to play sequences back-to-back that are less that 1 second long, - use the frame position to determine when to play the next sequence, instead - of SDL_CDStatus. - - This may be possible to fix with a clever usage of the AudioUnit API. - - 4. When new volumes are inserted, our volume information is not updated. The only way - to refresh this information is to reinit the CD-ROM subsystem of SDL. To fix this, - one would probably have to fix point 1 above first, then figure out how to register - for a notification when new media is mounted in order to perform an automatic - rescan for cdfs volumes. - - - - So, here comes a description of how this all works. - - < Initializing > - - To get things rolling, we have to locate mounted volumes that contain - audio (since nearly all Macs don't have analog audio-in on the sound card). - That's easy, since these volumes have a flag that indicates this special - filesystem. See DetectAudioCDVolumes() in CDPlayer.cpp for this code. - - Next, we parse the invisible .TOC.plist in the root of the volume, which gets us - the track information (number, offset, length, leadout, etc). See ReadTOCData() in - CDPlayer.cpp for the skinny on this. - - - < The Playback Loop > - - Now come the tricky parts. Let's start with basic audio playback. When a frame - range to play is requested, we must first find the .aiff files on the volume, - hopefully in the right order. Since these files all begin with a number "1 Audio Track", - etc, this is used to determine the correct track order. - - Once all files are determined, we have to find what file corresponds to the start - and length parameter to SDL_SYS_CDPlay(). Again, this is quite simple by walking the - cdrom's track list. At this point, we also save the offset to the next track and frames - remaining, if we're going to have to play another file after the first one. See - GetFileForOffset() for this code. - - At this point we have all info needed to start playback, so we hand off to the LoadFile() - function, which proceeds to do its magic and plays back the file. - - When the file is finished playing, CompletionProc() is invoked, at which time we can - play the next file if the previously saved next track and frames remaining - indicates that we should. - - - < Magic > - - OK, so it's not really magic, but since I don't fully understand all the hidden details it - seems like it to me ;-) The API's involved are the AudioUnit and AudioFile API's. These - appear to be an extension of CoreAudio for creating modular playback and f/x entities. - The important thing is that CPU usage is very low and reliability is very high. You'd - be hard-pressed to find a way to stutter the playback with other CPU-intensive tasks. - - One part of this magic is that it uses multiple threads, which carries the usual potential - for disaster if not handled carefully. Playback currently requires 4 additional threads: - 1. The coreaudio runloop thread - 2. The coreaudio device i/o thread - 3. The file streaming thread - 4. The notification/callback thread - - The first 2 threads are necessary evil - CoreAudio creates this no matter what the situation - is (even the SDL sound implementation creates theses suckers). The last two are are created - by us. - - The file is streamed from disk using a threaded double-buffer approach. - This way, the high latency operation of reading from disk can be performed without interrupting - the real-time device thread (which amounts to avoiding dropouts). The device thread grabs the - buffer that isn't being read and sends it to the CoreAudio mixer where it eventually gets - to the sound card. - - The device thread posts a notification when the file streaming thread is out of data. This - notification must be handled in a separate thread to avoid potential deadlock in the - device thread. That's where the notification thread comes in. This thread is signaled - whenever a notification needs to be processed, so another file can be played back if need be. - - The API in CDPlayer.cpp contains synchronization because otherwise both the notification thread - and main thread (or another other thread using the SDL CD api) can potentially call it at the same time. - -************************************************************************************/ - - -#include "SDL_cdrom.h" -#include "../SDL_syscdrom.h" - -#include "CDPlayer.h" - -#define kErrorFakeDevice "Error: Cannot proceed since we're faking a CD-ROM device.
