Qt Creator中的Gstreamer rtsp服务器链接

Question

我安装了Gstreamer并试图编译以下代码：

#include <gst/gst.h>
#include <gst/rtsp-server/rtsp-server.h>

int main (int argc, char *argv[])
{
  GMainLoop *loop;
  GstRTSPServer *server;
  GstRTSPMediaMapping *mapping;
  GstRTSPMediaFactory *factory;

  gst_init (&argc, &argv);
  loop = g_main_loop_new (NULL, FALSE);
  server = gst_rtsp_server_new ();
  mapping = gst_rtsp_server_get_media_mapping (server);
  factory = gst_rtsp_media_factory_new ();
  gst_rtsp_media_factory_set_launch (factory,
        "( videotestsrc is-live=1 ! x264enc ! rtph264pay )");

  gst_rtsp_media_factory_set_shared (factory, TRUE);
  gst_rtsp_media_mapping_add_factory (mapping, "/test", factory);
  g_object_unref (mapping);
  gst_rtsp_server_attach (server, NULL);
  g_main_loop_run (loop);

  return 0;
}

我和this question有同样的错误，

在函数main': test-launch01.c:(.text+0x64): undefined reference togst_rtsp_server_new的测试-Launch01.c：(.text+0x74)：未定义 引用gst\_rtsp\_server\_get\_media\_mapping' test-launch01.c:(.text+0x7d): undefined reference togst_rtsp_media_factory_new的test-launch01.c:(.text+0x95)：未定义 参考gst\_rtsp\_media\_factory\_set\_shared' test-launch01.c:(.text+0xad): undefined reference togst_rtsp_media_factory_set_launch‘测试-Launch01.c：(.text+0xc9)： 对gst\_rtsp\_media\_mapping\_add\_factory' test-launch01.c:(.text+0xe9): undefined reference togst_rtsp_server_attach‘collect2的未定义引用: ld返回了1个退出状态

我正在使用，下面是我的.pro文件：

QT +=核 QT -= gui +=控制台配置-= app_bundle CONFIG+=link_pkgconfig PKGCONFIG += gstreamer-0.10 TEMPLATE = app 源+= main.cpp /home/kato/ew-gst-sdk-linux-x86_64-2012.03-0/include/gstreamer-0.10 += INCLUDEPATH += /usr/include/glib-2.0 INCLUDEPATH += /usr/lib/x86_64-linux-gnu/glib-2.0/ += /usr/include/libxml2 2 LIBS += +=\-lgstreamer 0.10\ -lgstrtsp-0.10

是否正确链接到pkg-config gstreamer-rtsp-0.10 --libs ?？

我也犯了同样的错误。

Answer 1

我的.pro文件是：

    QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Gestion_Flux_Video
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp \
    streaming.cpp

HEADERS  += mainwindow.h \
    streaming.h

FORMS    += mainwindow.ui

INCLUDEPATH += /opt/gstreamer-sdk/include \
        /opt/gstreamer-sdk/include/gstreamer-0.10 \
        /opt/gstreamer-sdk/lib/glib-2.0/include \
        /opt/gstreamer-sdk/include/glib-2.0 \
        /opt/gstreamer-sdk/include/libxml2

LIBS += -L/opt/gstreamer-sdk/lib -lglib-2.0 \
                                -lgstreamer-0.10 \
                                -lgobject-2.0 \
                                -lgtk-x11-2.0 \
                                -lgstrtsp-0.10 \
                                -lgstapp-0.10 \
        -L/opt/gstreamer-sdk/include/gstreamer-0.10/gst/rtsp-server -lgstrtspserver-0.10

这份汇编对我来说很好。
