From 5bac3c3ce515cb588f3928431db4fe1c396d53e7 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sun, 26 Sep 2004 17:02:26 +0000 Subject: bum version number add new macro PA_API_VERSION for preprocessor level conditional compiling add new native APIs: - counter - cork & flush for record streams - add flags parameters to pa_stream_connect_xx() - new prebuf command - time api, and total latency calculator - return sample spec ability to cork source output streams dump server status on SIGHUP to syslog show sink input/source outputs status in cli-text.c don't flush esound output buffer when client disconnects move version api to polyplib-version.h git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@240 fefdeb5f-60dc-0310-8127-8f9354f1896f --- polyp/protocol-esound.c | 89 +++++++++++++++++++++++++++++-------------------- 1 file changed, 52 insertions(+), 37 deletions(-) (limited to 'polyp/protocol-esound.c') diff --git a/polyp/protocol-esound.c b/polyp/protocol-esound.c index 797263f6..79978740 100644 --- a/polyp/protocol-esound.c +++ b/polyp/protocol-esound.c @@ -62,6 +62,7 @@ struct connection { uint32_t index; + int dead; struct pa_protocol_esound *protocol; struct pa_iochannel *io; struct pa_client *client; @@ -76,14 +77,17 @@ struct connection { struct pa_source_output *source_output; struct pa_memblockq *input_memblockq, *output_memblockq; struct pa_defer_event *defer_event; + struct { struct pa_memblock *current_memblock; size_t memblock_index, fragment_size; } playback; - struct pa_memchunk scache_memchunk; - char *scache_name; - struct pa_sample_spec scache_sample_spec; + struct { + struct pa_memchunk memchunk; + char *name; + struct pa_sample_spec sample_spec; + } scache; }; struct pa_protocol_esound { @@ -195,9 +199,9 @@ static void connection_free(struct connection *c) { if (c->defer_event) c->protocol->core->mainloop->defer_free(c->defer_event); - if (c->scache_memchunk.memblock) - pa_memblock_unref(c->scache_memchunk.memblock); - pa_xfree(c->scache_name); + if (c->scache.memchunk.memblock) + pa_memblock_unref(c->scache.memchunk.memblock); + pa_xfree(c->scache.name); pa_xfree(c); } @@ -583,17 +587,17 @@ static int esd_proto_sample_cache(struct connection *c, esd_proto_t request, con strncpy(name+sizeof(SCACHE_PREFIX)-1, (char*) data+3*sizeof(int), ESD_NAME_MAX); name[sizeof(name)-1] = 0; - assert(!c->scache_memchunk.memblock); - c->scache_memchunk.memblock = pa_memblock_new(sc_length, c->protocol->core->memblock_stat); - c->scache_memchunk.index = 0; - c->scache_memchunk.length = sc_length; - c->scache_sample_spec = ss; - assert(!c->scache_name); - c->scache_name = pa_xstrdup(name); + assert(!c->scache.memchunk.memblock); + c->scache.memchunk.memblock = pa_memblock_new(sc_length, c->protocol->core->memblock_stat); + c->scache.memchunk.index = 0; + c->scache.memchunk.length = sc_length; + c->scache.sample_spec = ss; + assert(!c->scache.name); + c->scache.name = pa_xstrdup(name); c->state = ESD_CACHING_SAMPLE; - pa_scache_add_item(c->protocol->core, c->scache_name, NULL, NULL, &index); + pa_scache_add_item(c->protocol->core, c->scache.name, NULL, NULL, &index); ok = connection_write(c, sizeof(int)); assert(ok); @@ -747,29 +751,29 @@ static int do_read(struct connection *c) { } else if (c->state == ESD_CACHING_SAMPLE) { ssize_t r; - assert(c->scache_memchunk.memblock && c->scache_name && c->scache_memchunk.index < c->scache_memchunk.length); + assert(c->scache.memchunk.memblock && c->scache.name && c->scache.memchunk.index < c->scache.memchunk.length); - if ((r = pa_iochannel_read(c->io, (uint8_t*) c->scache_memchunk.memblock->data+c->scache_memchunk.index, c->scache_memchunk.length-c->scache_memchunk.index)) <= 0) { + if ((r = pa_iochannel_read(c->io, (uint8_t*) c->scache.memchunk.memblock->data+c->scache.memchunk.index, c->scache.memchunk.length-c->scache.memchunk.index)) <= 0) { pa_log(__FILE__": read() failed: %s\n", r == 0 ?
