使用 Gstreamer 從網絡攝像頭播放 rtsp stream

Question

我想從 IP 相機TS-WPTCAM中獲取 stream 視頻。 我可以使用rtsp://192.168.100.50:19112/ipcam_h264.sdp直接 stream vlc 中的視頻但是當我嘗試使用 Gstreamer 時，它不播放視頻。 下面是output。

Lnx-Workstation:~$ gst-launch-1.0 -v rtspsrc location="rtsp://192.168.100.50:19112/ipcam_h264.sdp" name=demux demux. ! queue max-size-buffers=2 ! rtph264depay ! autovideosink sync=false

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

我還嘗試像這樣使用playbin播放視頻：

Lnx-Workstation:~$ gst-launch-1.0 -v playbin uri=rtsp://192.168.100.50:19112/ipcam_h264.sdp uridecodebin0::source::latency=100

*** 文件源的 Playbin 有效。

錯誤似乎是一樣的。

Answer 1

您需要從RTP加載H264 ，但您忘記在將其傳遞給depay之前autovideosink進行解析和解碼。 我也不知道你為什么需要demux部分，因為你只使用視頻和一個 stream。嘗試以下操作：

gst-launch-1.0 -v rtspsrc location="rtsp://192.168.100.50:19112/ipcam_h264.sdp" ! queue max-size-buffers=2 ! rtph264depay ! h264parse ! decodebin ! autovideosink sync=false

Answer 2

不確定您的情況，但 IIRC 如果安裝了 plugins-ugly，某些 gstreamer 版本可能會出現 RTSP 身份驗證問題。 您可以嘗試：

sudo apt-get remove gstreamer1.0-plugins-ugly

如果還不夠，您可以分享 sdp 以獲得進一步的建議。

Answer 3

在這里使用mplayer ：

mplayer rtsp://username:password@IPADDRESS:PORT/your-path-to-stream
