gstreamer - dashsink mpd 段列表给出 404 错误，如何从绝对路径更改为相对路径？

Question

下面给出了我的 dashsink 管道，但它生成的 mpd 文件将 mpd-root-path 属性中提供的 baseurl 和绝对路径附加到段列表中。有什么建议么？

gst-launch-1.0 -v --gst-debug-no-color=1 dashsink name=dashsink mpd-baseurl=http://localhost mpd-root-path=/var/www/localhost/media/kls2iesj mpd-filename=live.mpd target-duration=10 min-buffer-time=2 minimum-update-period=5 dynamic=false use-segment-list=true muxer=ts dvbsrc modulation=5 adapter=0 frequency=147000000 delsys=dvb-c-b ! queue ! tsdemux ! mpegvideoparse ! decodebin ! x264enc bitrate=1200 key-int-max=60 ! video/x-h264,stream-format=byte-stream,profile=main ! dashsink.video_0

生成的mpd文件

当使用 mplayer 播放此文件时，它为段文件提供 404，因为它附加了完整的绝对路径 baseurl。： mplayer file:///var/www/localhost/media/kls2iesj/live.mpd 甚至 mplayer http://localhost/media/kls2iesj/live.mpd.
