Gstreamer如何将多个rtsp流输出到pyqt的窗口中

[user85604]

参考deepstreamer-rtsp-in-rtsp-out的python程序将多个rtsp源拼在一起输出，以下是关于元素设置的部分代码

        uri_decode_bins = []
        for i in range(len(sourceUrls)):
            sourceUrl = sourceUrls[i]
            if sourceUrl is None:
                continue
            if sourceUrl.find("rtsp://") == 0:
                is_live = True
            source_bin, uri_decode_bin = create_source_bin(i, Gst, sourceUrl, None)
            uri_decode_bins.append(uri_decode_bin)
            if not source_bin:
                sys.stderr.write("Unable to create source bin \n")
            self.pipeline.add(source_bin)
            padname = "sink_%u" % i
            sinkpad = streammux.request_pad_simple(padname)
            if not sinkpad:
                sys.stderr.write("Unable to create sink pad bin \n")
            srcpad = source_bin.get_static_pad("src")
            if not srcpad:
                sys.stderr.write("Unable to create src pad bin \n")
            srcpad.link(sinkpad)

        queue1 = Gst.ElementFactory.make("queue", "queue1")
        queue2 = Gst.ElementFactory.make("queue", "queue2")
        queue3 = Gst.ElementFactory.make("queue", "queue3")
        queue4 = Gst.ElementFactory.make("queue", "queue4")

        caps1 = Gst.Caps.from_string("video/x-raw(memory:NVMM), format=RGBA")
        filter1 = Gst.ElementFactory.make("capsfilter", "filter1")
        tilterRowNum = int((number_sources-1)/2)+1
        tilterColNum = 2
        if number_sources > 1:
            tiler = Gst.ElementFactory.make("nvmultistreamtiler", "nvtiler")
            self.pipeline.add(tiler)

        nvvidconv = Gst.ElementFactory.make("nvvideoconvert", "convertor")
        nvvidconv1 = Gst.ElementFactory.make("nvvideoconvert", "convertor1")

        videoconvert = Gst.ElementFactory.make("videoconvert", "videoconvert")
        #sink = Gst.ElementFactory.make("nv3dsink", "nv3d-sink")
        sink = Gst.ElementFactory.make("glimagesink", "sink")

我想将其输出到pyqt6的一个可视化窗口上，使用 glimagesink设置窗口句柄set_window_handle会提示“GstGLImageSinkBin object has no attribute set_window_handle”。
请问这是否是和输入的源的格式有关？该如何更改或者如何实现将多个rtsp流输出到pyqt6的窗口中？谢谢！

Hi,
We don’t have much experience about using glimagesink. Would see if other users can share experience. You can try the pipeline in gst-launch-1.0 command to make sure it is working first. And then apply to the code.

OK，thanks!
