This change will allow passing time data into the smoother while paused and then abruptly use that data without smoothing using the 'quick fixup' flag when resuming. Primary use case is allowing recording time graphs where the data recorded originates from a time before the stream was created. The resulting graft will be shifted and should not be smoothened to go through the origin.

Could that affect the pacat link somehow? What are the implications for client apps that link with the non-versioned libraries I've been building on solaris?

EAGAIN happens when the user requests a buffer size that is too large for the STREAMS layer to accept. We end up looping with EAGAIN every time we try to write out the rest of the buffer, which burns enough CPU time to trip the CPU limit. So, I reduce the buffer size with each EAGAIN. This gets us reasonably close to the largest usable buffer size. (Perhaps there's a better way to determine what that limit is, but I don't know how.) > > + > > + pa_rtpoll_set_timer_absolute(u->rtpoll, xtime0 + pa_bytes_to_usec(buffered_bytes / 2, &u->sink->sample_spec)); > > + } else { > > + pa_rtpoll_set_timer_disabled(u->rtpoll); > > } > > Hmm, you schedule audio via timers? Is that a good idea? Perhaps not. I won't know until I test on more hardware. But, given that we have rt priority and high resolution timers on solaris, I think it is OK in theory... The reason I used a timer was to minimise CPU usage and avoid the CPU limit. Recall that getting woken up by poll is not an option for playback unfortunately. We can arrange for a signal when the FD becomes writable, but that throws out the whole buffer size concept, which acts to reduce latency. > That really only makes sense if you have to deal with large buffers and > support rewinding. I've implemented rewind support, but I'm still not sure that I have understood the concept; I take it that we "rewind" (from the point-of-view of the renderer, not the sink) so that some rendered but as yet unplayed portion of the memblock/buffers can then be rendered again? > Please keep in mind that the system clock and the sound card clock > deviate.

Actually, in an earlier version I did use a smoother (after reading about that in the wiki). But because of the non-monotonic sample counter (bug?) I decided that it probably wasn't worth the added complexity so I removed it. I'll put the smoother back if I can figure out the problem with the sample counter. > > > + u->frame_size = pa_frame_size(&ss); > > > > - if ((fd = open(p = pa_modargs_get_value(ma, "device", DEFAULT_DEVICE), mode | O_NONBLOCK)) < 0) > > + u->buffer_size = 16384; > > It would appear more appropriate to me if the buffer size is adjusted by > the sample spec used. Done. > One last thing: it would probably be a good idea to allocate a pa_card > object and attach the sink and the source to it. It is possible to open /dev/audio twice by loading the solaris module twice -- once for the sink (passing record=0) and once for source (passing playback=0), thus giving seperate threads/LWPs for source and sink. It might be misleading to allocate two cards in that situation? > Right now pa_cards are mostly useful for switching profiles but even if > you do not allow switching profiles on-the-fly it is of some value to > find out via the cards object which source belongs to which sink. > > Otherwise I am happy! > > Thanks for your patch! I'd be thankful if you could fix the issues > pointed out and prepare another patch on top of current git! No problem. Patch follows. It also includes a portability fix for pa_realpath and a fix for a bug in the pa_signal_new() error path that causes signal data be freed if you attempt to register the same signal twice. > I hope I answered all your questions, Your answers were very helpful, thanks.

Could you please update it for current git? > Great. An updated patch is attached. For symmetry, I added this option to the alsa source module as well. The Ubuntu folks have customized pulse so much that it is difficult for me to get this version working on my system. For this patch I have only made sure that it compiles. But it does pretty much the same thing as the one for 0.9.14, which is working great for me. Thanks, Kyle
