From c6dffa0538819d2995d105e63b445359faa340d0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sebastian=20Dr=C3=B6ge?= Date: Thu, 5 Jun 2008 11:07:17 +0000 Subject: gst/interleave/: Properly implement duration and position queries in bytes format. We have to take the upstream reply... Original commit message from CVS: * gst/interleave/deinterleave.c: (gst_deinterleave_add_new_pads), (gst_deinterleave_src_query): * gst/interleave/interleave.c: (gst_interleave_src_query_duration), (gst_interleave_src_query): Properly implement duration and position queries in bytes format. We have to take the upstream reply and divide/multiply it by the number of channels to get the correct result. --- gst/interleave/deinterleave.c | 75 +++++++++++++++++++++++++++++++++++++++++++ gst/interleave/interleave.c | 10 ++++++ 2 files changed, 85 insertions(+) (limited to 'gst/interleave') diff --git a/gst/interleave/deinterleave.c b/gst/interleave/deinterleave.c index e8a10de7..6f2b0cef 100644 --- a/gst/interleave/deinterleave.c +++ b/gst/interleave/deinterleave.c @@ -91,6 +91,7 @@ static GstStaticPadTemplate src_template = GST_STATIC_PAD_TEMPLATE ("src%d", "endianness = (int) { LITTLE_ENDIAN , BIG_ENDIAN }, " "width = (int) { 32, 64 }") ); + static GstStaticPadTemplate sink_template = GST_STATIC_PAD_TEMPLATE ("sink", GST_PAD_SINK, GST_PAD_ALWAYS, @@ -147,11 +148,17 @@ enum }; static GstFlowReturn gst_deinterleave_chain (GstPad * pad, GstBuffer * buffer); + static gboolean gst_deinterleave_sink_setcaps (GstPad * pad, GstCaps * caps); + static GstCaps *gst_deinterleave_sink_getcaps (GstPad * pad); + static gboolean gst_deinterleave_sink_activate_push (GstPad * pad, gboolean active); static gboolean gst_deinterleave_sink_event (GstPad * pad, GstEvent * event); + +static gboolean gst_deinterleave_src_query (GstPad * pad, GstQuery * query); + static void gst_deinterleave_set_property (GObject * object, guint prop_id, const GValue * value, GParamSpec * pspec); static void gst_deinterleave_get_property (GObject * object, @@ -250,11 +257,14 @@ static void gst_deinterleave_add_new_pads (GstDeinterleave * self, GstCaps * caps) { GstPad *pad; + guint i; for (i = 0; i < self->channels; i++) { gchar *name = g_strdup_printf ("src%d", i); + GstCaps *srccaps; + GstStructure *s; pad = gst_pad_new_from_static_template (&src_template, name); @@ -276,6 +286,8 @@ gst_deinterleave_add_new_pads (GstDeinterleave * self, GstCaps * caps) gst_pad_set_caps (pad, srccaps); gst_pad_use_fixed_caps (pad); + gst_pad_set_query_function (pad, + GST_DEBUG_FUNCPTR (gst_deinterleave_src_query)); gst_pad_set_active (pad, TRUE); gst_element_add_pad (GST_ELEMENT (self), pad); self->srcpads = g_list_prepend (self->srcpads, gst_object_ref (pad)); @@ -292,11 +304,14 @@ static void gst_deinterleave_set_pads_caps (GstDeinterleave * self, GstCaps * caps) { GList *l; + GstStructure *s; + gint i; for (l = self->srcpads, i = 0; l; l = l->next, i++) { GstPad *pad = GST_PAD (l->data); + GstCaps *srccaps; /* Set channel position if we know it */ @@ -375,7 +390,9 @@ static gboolean gst_deinterleave_sink_setcaps (GstPad * pad, GstCaps * caps) { GstDeinterleave *self; + GstCaps *srccaps; + GstStructure *s; self = GST_DEINTERLEAVE (gst_pad_get_parent (pad)); @@ -384,7 +401,9 @@ gst_deinterleave_sink_setcaps (GstPad * pad, GstCaps * caps) if (self->sinkcaps && !gst_caps_is_equal (caps, self->sinkcaps)) { gint new_channels, i; + GstAudioChannelPosition *pos; + gboolean same_layout = TRUE; s = gst_caps_get_structure (caps, 0); @@ -476,6 +495,7 @@ static void __remove_channels (GstCaps * caps) { GstStructure *s; + gint i, size; size = gst_caps_get_size (caps); @@ -490,6 +510,7 @@ static void __set_channels (GstCaps * caps, gint channels) { GstStructure *s; + gint i, size; size = gst_caps_get_size (caps); @@ -506,7 +527,9 @@ static GstCaps * gst_deinterleave_sink_getcaps (GstPad * pad) { GstDeinterleave *self = GST_DEINTERLEAVE (gst_pad_get_parent (pad)); + GstCaps *ret; + GList *l; GST_OBJECT_LOCK (self); @@ -520,6 +543,7 @@ gst_deinterleave_sink_getcaps (GstPad * pad) ret = gst_caps_new_any (); for (l = GST_ELEMENT (self)->pads; l != NULL; l = l->next) { GstPad *ourpad = GST_PAD (l->data); + GstCaps *peercaps = NULL, *ourcaps; ourcaps = gst_caps_copy (gst_pad_get_pad_template_caps (ourpad)); @@ -542,6 +566,7 @@ gst_deinterleave_sink_getcaps (GstPad * pad) * otherwise assume that the peer accepts everything */ if (peercaps) { GstCaps *intersection; + GstCaps *oldret = ret; __remove_channels (peercaps); @@ -573,6 +598,7 @@ static gboolean gst_deinterleave_sink_event (GstPad * pad, GstEvent * event) { GstDeinterleave *self = GST_DEINTERLEAVE (gst_pad_get_parent (pad)); + gboolean ret; GST_DEBUG ("Got %s event on pad %s:%s", GST_EVENT_TYPE_NAME (event), @@ -605,6 +631,45 @@ gst_deinterleave_sink_event (GstPad * pad, GstEvent * event) return ret; } +static gboolean +gst_deinterleave_src_query (GstPad * pad, GstQuery * query) +{ + GstDeinterleave *self = GST_DEINTERLEAVE (gst_pad_get_parent (pad)); + + gboolean res; + + res = gst_pad_query_default (pad, query); + + if (res && GST_QUERY_TYPE (query) == GST_QUERY_DURATION) { + GstFormat format; + + gint64 dur; + + gst_query_parse_duration (query, &format, &dur); + + /* Need to divide by the number of channels in byte format + * to get the correct value.
