可能存在时间戳问题或这台计算机太慢

There maybe a timestamping problem or this computer is too slow

有人用 gstreamer 得到这个输出吗?

我正在尝试 gstreamer 与 rtp 从我的 latptop 到 nvidia xavier

我的发送管道就是这样

gst-launch-1.0 v4l2src ! videoconvert ! 'video/x-raw,format=(string)I420' ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=1234

我的客户端管道就是这样

gst-launch-1.0 -vvv udpsrc port=1234 ! application/x-rtp,payload=96 ! rtph264depay ! avdec_h264 ! xvimagesink

我得到以下输出,我的流也很慢而且滞后。

WARNING: from element /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: A lot of buffers are being dropped.
Additional debug info:
gstbasesink.c(2902): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0:

如有任何帮助,我们将不胜感激。谢谢!

CPU在这些场合的使用情况如何?我没有使用这个平台的经验 - 可能它的目的是 运行 GPU 上的大多数东西(比如视频解码和显示)。

尝试 sync=false 视频接收器。它可能仍然有延迟,但不会丢掉任何帧。因此,也许可以通过观察此管道获得更多信息。

使用 autovideoconvert ! autovideosink 作为接收器而不是使用 xvimagesink 怎么样?

考虑使用 rtpbin 元素而不是手动执行 RTP 部分。 bin 做了很多智能缓冲等,可能在这里有所帮助。

当然还要仔细检查笔记本电脑编码器端是否没有出现问题..
