This is to update the plug-in to the newer 3.x plug-in semantics. This fixes the "unpausing" bug which afaiu was an effect of using the version 2.x plug-in with audacious version 3.x. This fixes other similar bugs as well (eg. crashes during volume changes). comments? ok? -- Alexandre Index: Makefile =================================================================== RCS file: /cvs/ports/audio/audacious-plugins/Makefile,v retrieving revision 1.43 diff -u -p -r1.43 Makefile --- Makefile 6 Apr 2012 14:38:01 -0000 1.43 +++ Makefile 4 May 2012 07:57:56 -0000 @@ -6,7 +6,7 @@ COMMENT = input and output plugins for V = 3.2 DISTNAME = audacious-plugins-$V -REVISION = 2 +REVISION = 3 CATEGORIES = audio multimedia Index: files/sndio.c =================================================================== RCS file: /cvs/ports/audio/audacious-plugins/files/sndio.c,v retrieving revision 1.3 diff -u -p -r1.3 sndio.c --- files/sndio.c 20 Mar 2012 19:10:56 -0000 1.3 +++ files/sndio.c 4 May 2012 07:57:56 -0000 @@ -15,11 +15,13 @@ * OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. */ +#include <errno.h> +#include <poll.h> +#include <pthread.h> #include <sndio.h> #include <stdio.h> #include <stdlib.h> #include <string.h> -#include <pthread.h> #include <gtk/gtk.h> #include <audacious/plugin.h> #include <audacious/misc.h> @@ -39,6 +41,8 @@ void sndio_get_volume(int *, int *); void sndio_set_volume(int, int); bool_t sndio_open(int, int, int); void sndio_close(void); +int sndio_buffer_free(void); +void sndio_period_wait(void); void sndio_write(void *, int); void sndio_pause(bool_t); void sndio_flush(int); @@ -56,12 +60,10 @@ static struct sio_par par; static struct sio_hdl *hdl; static long long rdpos; static long long wrpos; -static int paused, flushed, volume; -static int flush_time, pause_flag, volume_target; -static int writing, pause_pending, flush_pending, volume_pending; +static int paused, restarted, volume; +static int pause_pending, flush_pending, volume_pending; static int bytes_per_sec; static pthread_mutex_t mtx; -static pthread_t sndio_thread; static GtkWidget *configure_win; static GtkWidget *adevice_entry; @@ -80,6 +82,8 @@ AUD_OUTPUT_PLUGIN .open_audio = sndio_open, .write_audio = sndio_write, .close_audio = sndio_close, + .buffer_free = sndio_buffer_free, + .period_wait = sndio_period_wait, .flush = sndio_flush, .pause = sndio_pause, .output_time = sndio_output_time, @@ -100,70 +104,62 @@ static struct fmt_to_par { {FMT_U32_LE, 32, 0, 1}, {FMT_U32_BE, 32, 0, 0} }; +static const gchar * const sndio_defaults[] = { + "volume", "100", + "audiodev", "", + NULL, +}; + static void -volume_do(int v) +reset(void) { - if (writing) { - volume_target = v; - volume_pending = 1; - } else { - if (hdl) - sio_setvol(hdl, v * SIO_MAXVOL / 100); - volume_pending = 0; + if (!restarted) { + restarted = 1; + sio_stop(hdl); + sio_start(hdl); + rdpos = wrpos; } } static void -pause_do(int flag) +wait_ready(void) { - if (writing) { - pause_flag = flag; - pause_pending = 1; - } else { - if (flag && !paused && !flushed) { - sio_stop(hdl); - sio_start(hdl); - rdpos = wrpos; - } - paused = flag; + int n; + struct pollfd pfds[16]; + + if (volume_pending) { + sio_setvol(hdl, volume * SIO_MAXVOL / 100); + volume_pending = 0; + } + if (flush_pending) { + reset(); + flush_pending = 0; + } + if (pause_pending) { + if (paused) + reset(); pause_pending = 0; } -} - -static void -flush_do(int time) -{ - if (writing) { - flush_time = time; - flush_pending = 1; - } else { - if (!paused && !flushed) { - sio_stop(hdl); - sio_start(hdl); + if (paused) { + pthread_mutex_unlock(&mtx); + usleep(20000); + pthread_mutex_lock(&mtx); + return; + } + n = sio_pollfd(hdl, pfds, POLLOUT); + if (n != 0) { + pthread_mutex_unlock(&mtx); + while (poll(pfds, n, -1) < 0) { + if (errno != EINTR) { + perror("poll"); + exit(1); + } } - rdpos = wrpos = (long long)time * bytes_per_sec / 1000; - flush_pending = 0; - flushed = 1; + pthread_mutex_lock(&mtx); } + (void)sio_revents(hdl, pfds); } -void -sndio_about(void) -{ - static GtkWidget *about = NULL; - - audgui_simple_message(&about, GTK_MESSAGE_INFO, - _("About Sndio Output Plugin"), - _("Sndio Output Plugin\n\n" - "Written by Thomas Pfaff <tpf...@tp76.info>\n")); -} - -static const gchar * const sndio_defaults[] = { - "volume", "100", - "audiodev", "", - NULL, -}; - bool_t sndio_init(void) { @@ -185,6 +181,17 @@ sndio_cleanup(void) } void +sndio_about(void) +{ + static GtkWidget *about = NULL; + + audgui_simple_message(&about, GTK_MESSAGE_INFO, + _("About Sndio Output Plugin"), + _("Sndio Output Plugin\n\n" + "Written by Thomas Pfaff <tpf...@tp76.info>\n")); +} + +void sndio_get_volume(int *l, int *r) { pthread_mutex_lock(&mtx); @@ -198,7 +205,7 @@ sndio_set_volume(int l, int r) /* Ignore balance control, so use unattenuated channel. */ pthread_mutex_lock(&mtx); volume = l > r ?
