Where the hell is definition of struct id3_file????
by tj 29 Sep '06

29 Sep '06

In trying to learn how to use libid3, since there sems to be no documentatio. I am looking at soure trying to figure out how to use it. The first problem is the practically every call uses a pointer to a "struct id3_file" . Now, the problem is that there is no definition for id3_file structure in any .h file. I finally found it in file.c, a source file. How the hell are you supposed to use it in your app when the prototype is in a package source file? Seems that something is really broken here. tj

madplay watchdog signals?
by Matthew Rubenstein 23 Feb '05

23 Feb '05

Howdy - I'm running madplay on an iPaq3670/Familiar0.8 (ARM arch) with a CF ethernet card. I play Shoutcast MP3 streams by piping wget -o - <stream-url> | madplay - , and it works really well - realtime decoding, full sound, no fan, otherwise useless HW :). But every 10-30 minutes or so, I get a net/Inet hiccup that interrupts the stream connection. wget hangs, and no data gets to madplay. I want to set up another process to watch madplay, and kill it when it stops playing, then restart it - this always works manually. But madplay doesn't seem to reliably emit output status info. the --verbose flag sends an updated "seconds" counter, but, since it doesn't send any newlines, it can't be parsed by piping it to a "read" in a shell script. And redirecting it to a file doesn't reliably update the file's ctime, either. If I "madplay -o wave:- | tee >/dev/dsp |watchdog", the system performance grinds to a halt, unlistenable. I just want any technique that keeps my wget | madplay pipeline restarted all the time, with a minimum of restarts, which make an audible "clunk". Short of recoding (and cross-compiling) libmad with extra status hooks, is there any way to keep this little engine churning? -- (C) Matthew Rubenstein

Winamp MAD plugin buffer
by Andrei Tarkovsky 01 Feb '05

01 Feb '05

The original Nullsoft Winamp MP3 decoder has a option called "Full file buffering". This option loads the entire MP3 into memory rather than reading it from disc during playback. This completely eliminates skipping as well as allowing MP3s to be deleted while they are still playing back... a very useful function for cleaning up large MP3 collections. I was wondering if there is any way to achieve a similar buffer with the MAD winamp input plug. Any advice would be greatly appreciated. Cheers, Tarkovsky
