From 5f360f3b133301fcd33cbc3998c369354134e2bc Mon Sep 17 00:00:00 2001 From: Julien Isorce Date: Fri, 1 Nov 2013 16:57:15 +0000 Subject: [PATCH] tests/check: add rtpaux::test_simple_rtpbin_aux It shows how to use "set-aux-receive" and "set-aux-send" properties of rtpbin to set rtprtxsend and rtprtxreceive Build 2 pipelines, one for rtpbin as a sender and one for rtobin as a receive. Then transmit an audio stream. It also drops some packets to activate restransmission and check they are actually retransmited. --- tests/check/Makefile.am | 4 + tests/check/elements/.gitignore | 1 + tests/check/elements/rtpaux.c | 407 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 412 insertions(+) create mode 100644 tests/check/elements/rtpaux.c diff --git a/tests/check/Makefile.am b/tests/check/Makefile.am index 8e7f435..9c3e135 100644 --- a/tests/check/Makefile.am +++ b/tests/check/Makefile.am @@ -142,6 +142,7 @@ check_PROGRAMS = \ elements/rganalysis \ elements/rglimiter \ elements/rgvolume \ + elements/rtpaux \ elements/rtpcollision \ elements/rtp-payloading \ elements/rtpbin \ @@ -334,6 +335,9 @@ elements_rtpsession_LDADD = $(GST_PLUGINS_BASE_LIBS) -lgstrtp-$(GST_API_VERSION) elements_rtpcollision_CFLAGS = $(GST_PLUGINS_BASE_CFLAGS) $(CFLAGS) $(AM_CFLAGS) elements_rtpcollision_LDADD = $(GST_PLUGINS_BASE_LIBS) -lgstnet-$(GST_API_VERSION) -lgstrtp-$(GST_API_VERSION) $(GIO_LIBS) $(LDADD) +elements_rtpaux_CFLAGS = $(GST_PLUGINS_BASE_CFLAGS) $(CFLAGS) $(AM_CFLAGS) +elements_rtpaux_LDADD = $(GST_PLUGINS_BASE_LIBS) -lgstrtp-$(GST_API_VERSION) $(LDADD) + # FIXME: configure should check for gdk-pixbuf not gtk # only need video.h header, not the lib elements_gdkpixbufsink_CFLAGS = \ diff --git a/tests/check/elements/.gitignore b/tests/check/elements/.gitignore index e6b0f56..dd17aac 100644 --- a/tests/check/elements/.gitignore +++ b/tests/check/elements/.gitignore @@ -47,6 +47,7 @@ rganalysis rglimiter rgvolume rtp-payloading +rtpaux rtpbin rtpbin_buffer_list rtpcollision diff --git a/tests/check/elements/rtpaux.c b/tests/check/elements/rtpaux.c new file mode 100644 index 0000000..a2fb02f --- /dev/null +++ b/tests/check/elements/rtpaux.c @@ -0,0 +1,407 @@ +/* GStreamer + * + * Copyright (C) 2013 Collabora Ltd. + * @author Julien Isorce + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
