From 62f56a9f6b01c277a8c4f15625473df4b73bd208 Mon Sep 17 00:00:00 2001 From: Arun Raghavan Date: Sun, 10 Apr 2011 16:24:33 +0530 Subject: sink-input: Provide more information to client when format is lost When the sink format changes and we kill the stream, clients need a way to know (a) what device they should reconnect to, and (b) what the stream running time was when the stream got killed (pa_stream_get_time() won't work after the stream has been killed). This adds these two bits of information in the event callback's proplist parameter. --- src/pulse/stream.c | 8 ++++++++ src/pulsecore/sink-input.c | 6 +++++- 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/src/pulse/stream.c b/src/pulse/stream.c index bd2e6ca1..6c055a5c 100644 --- a/src/pulse/stream.c +++ b/src/pulse/stream.c @@ -766,6 +766,14 @@ void pa_command_stream_event(pa_pdispatch *pd, uint32_t command, uint32_t tag, p if (s->state != PA_STREAM_READY) goto finish; + if (pa_streq(event, PA_STREAM_EVENT_FORMAT_LOST)) { + /* Let client know what the running time was when the stream had to be + * killed */ + pa_usec_t time; + if (pa_stream_get_time(s, &time) == 0) + pa_proplist_setf(pl, "stream-time", "%llu", (unsigned long long) time); + } + if (s->event_callback) s->event_callback(s, event, pl, s->event_userdata); diff --git a/src/pulsecore/sink-input.c b/src/pulsecore/sink-input.c index f0558f40..b21cfae0 100644 --- a/src/pulsecore/sink-input.c +++ b/src/pulsecore/sink-input.c @@ -1594,8 +1594,12 @@ int pa_sink_input_finish_move(pa_sink_input *i, pa_sink *dest, pa_bool_t save) { return -PA_ERR_NOTSUPPORTED; if (pa_sink_input_is_passthrough(i) && !pa_sink_check_format(dest, i->format)) { + pa_proplist *p = pa_proplist_new(); pa_log_debug("New sink doesn't support stream format, sending format-changed and killing"); - pa_sink_input_send_event(i, PA_STREAM_EVENT_FORMAT_LOST, NULL); + /* Tell the client what device we want to be on if it is going to + * reconnect */ + pa_proplist_sets(p, "device", dest->name); + pa_sink_input_send_event(i, PA_STREAM_EVENT_FORMAT_LOST, p); return -PA_ERR_NOTSUPPORTED; } -- cgit
