Gstreamer参数出错

Question

我的代码基于Google coral对象跟踪器示例：https://github.com/google-coral/example-object-tracker/tree/master/gstreamer

当我尝试运行代码时，我遇到了以下Gstreamer问题：

Gstreamer pipeline:
 souphttpsrc location=https://bitmovin-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8 ! tee name=t
            t. ! queue max-size-buffers=1 leaky=downstream ! videoconvert ! videoscale ! video/x-raw,width=300,height=225 ! videobox name=box autocrop=true
               ! video/x-raw,format=RGB,width=300,height=300 ! appsink name=appsink emit-signals=true max-buffers=1 drop=true
            t. ! queue max-size-buffers=1 leaky=downstream ! videoconvert
               ! rsvgoverlay name=overlay ! videoconvert ! ximagesink sync=false

Error: gst-stream-error-quark: Internal data stream error. (1): gstqueue.c(988): gst_queue_handle_sink_event (): /GstPipeline:pipeline0/GstQueue:queue0:
streaming stopped, reason not-negotiated (-4)

我对Gstreamer不放心，但据我所知，queue参数可能有问题

有什么东西可以让它正常工作吗
