androidudp传输h264,如何使用udp传输h264gstreamer

我试图用h264传输视频。 Source是一个Axis相机。我设法使用多播传输jpeg&＃xff0c;但不是h264。如何使用udp传输h264 gstreamer

使用JPEG我用下面的命令&＃xff1a;

gst-launch-1.0 udpsrc uri&＃61;udp://239.194.0.177:1026 ! application/x-rtp,encoding-name&＃61;JPEG,payload&＃61;26 ! rtpjpegdepay ! jpegdec ! autovideosink

我试图流H264&＃xff0c;但是失败了&＃xff0c;使用下面的命令&＃xff1a;

gst-launch-1.0 -v udpsrc host&＃61;239.194.0.177 port&＃61;1026 ! rtph264depay ! ffdec_h264 ! xvimagesink

我收到以下错误&＃xff1a;

ERROR: pipeline could not be constructed: no element "udpsrc".

使用此行&＃xff1a;

gst-launch-1.0 udpsrc uri&＃61;udp://239.194.0.177:1026 ! application/x-rtp,media&＃61;video,clock-rate&＃61;90000,encoding-name&＃61;H264 ! rtph264depay ! h264parse

我没有得到任何错误&＃xff0c;但没有视频流&＃xff0c;这是印在终端&＃xff1a;

Setting pipeline to PAUSED ...

Pipeline is live and does not need PREROLL ...

Setting pipeline to PLAYING ...

New clock: GstSystemClock

我想从以下页面的命令&＃xff1a;

但无法让它工作。

当以verbos模式运行时&＃xff0c;我得到更多信息。

命令&＃xff1a;

gst-launch-1.0 -v udpsrc uri&＃61;udp://239.194.0.177:1026 ! application/x-rtp, media&＃61;video, payload&＃61;96, encoding-name&＃61;H264 ! rtph264depay ! avdec_h264 ! videoconvert ! fakesink

输出&＃xff1a;

尝试与-v GST推出详细模式做-1.0 udpsrc uri &＃61; udp&＃xff1a;//239.194.0.177&＃xff1a;1026&＃xff01; application/x-rtp&＃xff0c;media &＃61; video&＃xff0c;clock-rate &＃61; 90000&＃xff0c;encoding-name &＃61; H264&＃xff01; rtph264depay&＃xff01; h264parse&＃xff01; fakesink - 尝试在管道中的每个元素之后添加fakesink&＃xff0c;以确定哪个元素导致问题。 –
