我想用GStreamer支持构建opencv

我根据以下指南从源代码(版本1.8.1)构建了GStreamer: 我的主目录中有“gstreamer_build”文件夹,其中包含带有以下内容的“bin”文件夹:

gst-device-monitor-1.0 gst-discoverer-1.0 gst-inspect-1.0 gst-launch-1.0 gst-play-1.0 gst-stats-1.0 gst-typefind-1.0 报告

我已将此路径添加到环境变量path中

当我使用cmake时,例如:

cmake-D cmake_BUILD_TYPE=发行版-D CMAKE_INSTALL_PREFIX=/usr/local-D OPENCV\u EXTRA\u MODULES\u PATH=~/OPENCV\u contrib/MODULES-D BUILD\u OPENCV\u python3=ON-D带\u GSTREAMER=ON-D带\u FFMPEG=OFF

我得到以下输出,清楚地表明未找到gstreamer:

有人能帮我吗?

我也有同样的问题

gstreamer base对应于libgstbase-1.0.so(或libgstbase-0.10.so),可在包libgstreamer1.0-0(或libgstreamer0.10-0,视情况而定)中找到。下面,我们安装'-dev'包

我在包libgstreamer-plugins-base1.0-dev中找到的其他库(libgst-video、libgst-app、libgst-riff、libgst-pbutils)(同样,替换您希望使用的版本,v0.1或v1.0)

因此,应使用以下命令安装缺少的依赖项:

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

重复cmake命令,可能会事先清除构建目录的内容。

如果您只是在开发Gstreamer应用程序,下面的内容对我很有用

# GStreamer CMake building
cmake_minimum_required(VERSION 3.3)
project(GStreamerHello)

set(PKG_CONFIG_USE_CMAKE_PREFIX_PATH ON)
find_package(PkgConfig REQUIRED)
if ( NOT (PKGCONFIG_FOUND))
      message(FATAL_ERROR "Please Install PPkgConfig: CMake will Exit")
endif()
pkg_check_modules(GST REQUIRED gstreamer-1.0>=1.8)
if ( NOT (GST_FOUND))
      message(FATAL_ERROR "Please Install Gstreamer Dev: CMake will Exit")
endif()
set(ENV{PKG_CONFIG_PATH})

include_directories("${GST_INCLUDE_DIRS}")

link_libraries(${GST_LIBRARIES})

add_executable(gstreamerSrvc  src/hello_gstreamer.cc)
add_dependencies(gstreamerSrvc vsphere_header )
target_link_libraries(gstreamerSrvc ${GST_LIBRARIES}  )
注意-如果您需要GStreamer的dev docker,请参阅下面的内容;对于您的问题,它还包括使用OpenCV编译的部分; 详情请浏览

在Windows上没有“sudo apt install…”我也在我的PATH环境变量中设置了所有路径,但仍然存在相同的问题。在设置了以下CMake选项后,我已使其正常工作:

  • 仅将“WITH\u GSTREAMER”选项设置为True,“WITH\u GSTREAMER\u 0\u 10”必须为FALSE
  • 添加新条目“GSTREAMER_DIR”=(GSTREAMER的路径) 对我来说是“C:/gstreamer/1.0/x86_64” 我找到了这个解决方案

  • 我的OpenCV版本:3.4.3

    添加新条目
    “GSTREAMER\u DIR”=(GSTREAMER的路径)
    对我来说很有效(
    带\u GSTREAMER true
    )。在我的版本中没有带有\u GSTREAMER\u 0\u 10的

    老兄,你帮我节省了很多时间!谢谢分享。你如何与百胜合作?我试过了,但百胜似乎无法访问libgstreamer存储库中的任何内容。@DanO-尽管这篇文章在撰写本文时已有3年历史,但它仍然有效!也许您知道如何安装libavresample以在所有行中都获得YES?这对我很有用,谢谢!
