Question

我使用Gstreamer版本1.8.3和以下管道来发送和接收rtp / rtcp流。

瓦尔：

export SAMPLE="overwatch.mjpeg"
export IMAGE_CAPS="image/jpeg,width=1280,height=720,framerate=1/10,format=I420"

监听器：

test_play_rtpbin(){
    gst-launch-1.0 --gst-debug=3 rtpbin name=rtpbin \
        udpsrc port=25000 ! application/x-rtp,media=video,payload=26,clock-rate=90000,encoding-name=JPEG,width=1280,height=720 ! rtpbin.recv_rtp_sink_0 \
        rtpbin ! rtpjpegdepay ! queue ! jpegparse ! jpegdec ! videoconvert ! fpsdisplaysink \
        udpsrc port=25001 ! rtpbin.recv_rtcp_sink_0 \
        rtpbin.send_rtcp_src_0 ! udpsink port=25005 host="192.168.0.33" sync=false async=false
}

出版商：

test_record_rtpbin(){
    gst-launch-1.0 --gst-debug=3 rtpbin name=t \
        multifilesrc location=$SAMPLE loop=true ! queue ! $IMAGE_CAPS ! jpegparse ! $IMAGE_CAPS ! queue ! rtpjpegpay pt=26 ! application/x-rtp,media=video,payload=26,clock-rate=90000,encoding-name=JPEG,width=1280,height=720 ! t.send_rtp_sink_0 \
        t.send_rtp_src_0 ! udpsink port=25000 host="192.168.0.33" \
        t.send_rtcp_src_0 ! udpsink port=25001 host="192.168.0.33" sync=false async=false \
        udpsrc port=25005 ! t.recv_rtcp_sink_0
}

但由于某种原因，它不断向我发出以下错误：

示例文件具有以下格式：

当我仅使用rtp时，管道工作，但是当我尝试运行一个简单的rtpbin示例时，它会一直失败。请帮忙！

Answer 1

在使用其他gstreamer版本/配置测试后感到愚蠢，一个简单的错过，在test_play_rtpbin bash函数中，我错过了一点。

这条线 rtpbin ! rtpjpegdepay ! queue...应该是 rtpbin. ! rtpjpegdepay ! queue...

Gstreamer 1.8.3 rtpbin和rtpjpegpayload引发内部数据流错误
