From: Edward Hervey Date: Thu, 28 Apr 2022 08:46:34 +0000 (+0200) Subject: mssdemux2: Ensure stream/track uniqueness X-Git-Tag: 1.22.0~1716 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2ec79418df0dd2de8d4f4d8e35459464497ef146;p=platform%2Fupstream%2Fgstreamer.git mssdemux2: Ensure stream/track uniqueness If there is more than one track of the same type (say audio), we would end up creating several stream/types with the same name. Instead use the MSS stream name property to make them unique Part-of: --- diff --git a/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssdemux.c b/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssdemux.c index 843f0c6..3175eff 100644 --- a/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssdemux.c +++ b/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssdemux.c @@ -369,14 +369,28 @@ gst_mss_demux_setup_streams (GstAdaptiveDemux * demux) GstStreamType stream_type = gst_stream_type_from_mss_type (gst_mss_stream_get_type (manifeststream)); - const gchar *lang, *stream_id = gst_stream_type_get_name (stream_type); - gchar *name; + const gchar *lang = gst_mss_stream_get_lang (manifeststream); + const gchar *name = gst_mss_stream_get_name (manifeststream); + gchar *stream_id; GstCaps *caps; GstTagList *tags = NULL; - name = g_strdup_printf ("mss-stream-%s", stream_id); - mss_stream = g_object_new (GST_TYPE_MSS_DEMUX_STREAM, "name", name, NULL); - g_free (name); + if (name) + stream_id = + g_strdup_printf ("mss-stream-%s-%s", + gst_stream_type_get_name (stream_type), + gst_mss_stream_get_name (manifeststream)); + else if (lang) + stream_id = + g_strdup_printf ("mss-stream-%s-%s", + gst_stream_type_get_name (stream_type), lang); + else + stream_id = + g_strdup_printf ("mss-stream-%s", + gst_stream_type_get_name (stream_type)); + + mss_stream = + g_object_new (GST_TYPE_MSS_DEMUX_STREAM, "name", stream_id, NULL); stream = GST_ADAPTIVE_DEMUX2_STREAM_CAST (mss_stream); stream->stream_type = stream_type; @@ -391,7 +405,6 @@ gst_mss_demux_setup_streams (GstAdaptiveDemux * demux) caps = gst_mss_stream_get_caps (mss_stream->manifest_stream); gst_adaptive_demux2_stream_set_caps (stream, create_mss_caps (mss_stream, caps)); - lang = gst_mss_stream_get_lang (mss_stream->manifest_stream); if (lang != NULL) tags = gst_tag_list_new (GST_TAG_LANGUAGE_CODE, lang, NULL); @@ -399,6 +412,7 @@ gst_mss_demux_setup_streams (GstAdaptiveDemux * demux) GST_STREAM_FLAG_NONE, (gchar *) stream_id, create_mss_caps (mss_stream, caps), tags); + g_free (stream_id); gst_adaptive_demux2_add_stream (demux, stream); gst_adaptive_demux2_stream_add_track (stream, track); gst_adaptive_demux_track_unref (track); diff --git a/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssmanifest.c b/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssmanifest.c index 514033a..110aa68 100644 --- a/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssmanifest.c +++ b/subprojects/gst-plugins-good/ext/adaptivedemux2/mss/gstmssmanifest.c @@ -44,6 +44,7 @@ GST_DEBUG_CATEGORY_EXTERN (mssdemux2_debug); #define MSS_PROP_DURATION "d" #define MSS_PROP_DVR_WINDOW_LENGTH "DVRWindowLength" #define MSS_PROP_LANGUAGE "Language" +#define MSS_PROP_NAME "Name" #define MSS_PROP_NUMBER "n" #define MSS_PROP_REPETITIONS "r" #define MSS_PROP_STREAM_DURATION "Duration" @@ -84,6 +85,7 @@ struct _GstMssStream gchar *url; gchar *lang; + gchar *name; GstMssFragmentParser fragment_parser; @@ -254,6 +256,7 @@ _gst_mss_stream_init (GstMssManifest * manifest, GstMssStream * stream, stream->xmlnode = node; /* get the base url path generator */ + stream->name = (gchar *) xmlGetProp (node, (xmlChar *) MSS_PROP_NAME); stream->url = (gchar *) xmlGetProp (node, (xmlChar *) MSS_PROP_URL); stream->lang = (gchar *) xmlGetProp (node, (xmlChar *) MSS_PROP_LANGUAGE); @@ -263,12 +266,14 @@ _gst_mss_stream_init (GstMssManifest * manifest, GstMssStream * stream, * of the manifest. */ + GST_DEBUG ("lang '%s' url %s", stream->lang, stream->url); GST_DEBUG ("Live stream: %s, look-ahead fragments: %" G_GUINT64_FORMAT, manifest->is_live ?
