我正在尝试使用Gstreamer流式传输相机和麦克风音频视频。 使用Odroid C1 +作为服务器，使用PC作为客户端。 当我使用lan电缆时，它是完美的。但是当我使用WiFi时，它的性能会大大降低。
我用过
$ gst-launch-1.0 v4l2src ! gdppay ! tcpserversink host=localhost port=5000 alsasrc device="hw:1,0" ! gdppay ! tcpserversink host=localhost port=6000
$ gst-launch-1.0 tcpclientsrc host=localhost port=5000 ! gdpdepay ! autovideosink sync=false tcpclientsrc host=localhost port=6000 ! gdpdepay ! autoaudiosink sync=false
和
$ gst-launch-1.0 v4l2src ! videoconvert ! x264enc tune=zerolatency ! rtph264pay ! gdppay ! tcpserversink host=localhost port=5000 sync=false alsasrc device='hw:0,0' ! gdppay ! tcpserversink host=localhost port=6000 sync=false
$ gst-launch-1.0 tcpclientsrc host=localhost port=5000 ! gdpdepay ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false tcpclientsrc host=localhost port=6000 ! gdpdepay ! autoaudiosink sync=false
如何最大化Gstreamer流媒体的性能， 并同步视频和音频？
更新
$ gst-launch-1.0 v4l2src ! vaapih264enc ! rtph264pay ! gdppay ! tcpserversink host=localhost port=5000
