Gstreamer问题与gst启动的网络流

Question

Gstreamer非常新，但我正在尝试使用Gstreamer命令实现一个网络流。到目前为止，我已经成功地让管道使用了视频filesrc，但是当我尝试将一个文件to放在它的位置时，我就有麻烦了。以下是我尝试过的

• 获取..mov/..mkv文件和流 gst-启动-ve gstrtpbin name=rtpbin文件bbb位置=/home/user/Gstreamer_projects/test_视频/bbb_short_1080p.mkv！马特罗斯卡德姆！h264parse！rtph264pay！rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0！排队！host=192.168.1.21 port=5000 rtpbin.send_rtcp_src_0！host=192.168.1.21 port=5001 sync=false async=false udpsrc port=5005！rtpbin.recv_rtcp_sink_

终端上的输出是

    Pipeline is live and does not need PREROLL ...

     Setting pipeline to PLAYING ...

• 将上述文件转换为YUV，然后进行流处理。这是可行的，但在2-3 3fps时非常缓慢。

如果有人知道如何修复管道来正确地解析文件或提高x264enc在Gstreamer中的性能，我将非常感激！

您可以尝试在h264parse元素之前添加一个队列元素。另外，在管道中指定matroskademux的视频src pad。
