gst_parse_launch是GStreamer框架中的一个函数,用于解析并执行一个GStreamer管道描述字符串。它可以将一个字符串解析为一个GstPipeline对象,并自动创建和连接管道中的元素。该函数的输出是一个GstPipeline对象。 命令行gst_launch是GStreamer框架中的一个命令行工具,用于执行一个GStreamer管道描述字符串。它可以直...
当调用一个函数时出了通过函数名来调用之外,还可以通过指向该函数的指针变量来调用。切记,和一切指针变...
我是gstreamer的新手,我无法为我的rtsp链接将gst_parse_launch()与URL_RTSP变量连接起来。 这里没有变量URL_RTSP,它可以工作: /* Build the pipeline */ pipeline = gst_parse_launch("rtspsrc protocols=tcp location=rtsp://user:pass@protocol:port/cam/realmonitor?channel=1&subtype=0 latency=300 ! deco...
bash g++ gst_launch_example.cpp -o gst_launch_example `pkg-config --cflags --libs gstreamer-1.0` 然后,你可以运行生成的可执行文件来查看效果: bash ./gst_launch_example 这样,你就使用C++代码模拟了gst-launch-1.0命令的功能。
parse_launch("v4l2src device="/dev/video1" ! image/jpeg,width=640,height=480,framerate=30/1 ! jpegdec ! aspectratiocrop aspect-ratio=16/9 ! autovideosink") # Set up the gstreamer pipeline # self.player = Gst.parse_launch("v4l2src ! autovideosink") # self.player = Gst.parse_launch...
the dot that has to be used after the BINTYPE. You will almost never need this functionality, it is only really useful for applications using the gst_launch_parse() API with 'bin' as bintype. That way it is possible to build partial pipelines instead of a full-fledged top-level ...
pipeline = gst.parse_launch("...") bus = pipeline.get_bus() msg=bus.timed_pop(gst.MESSSAGE_EOS | gst.MESSAGE_ERROR, gst.CLOCK_TIME_NONE) if msg.type == gst.MESSAGE_ERROR: print "Error!" else: print "Done" Feel free to submit a patch to fix up the exit code regardless, but...

The `gst-launch-1.0` command parses this description, instantiates the required elements, links them together, and starts the pipeline. It provides a convenient way to experiment with GStreamer's capabilities and debug media processing issues. This tool is commonly used for tasks like playing ...
