視頻流錯誤的 Gstreamer rtsp 管道

Question

嘗試使用 gstreamer 連接到 rtsp 視頻流時遇到問題。 視頻流源自 IP 攝像頭。

在 vlc 和 opencv（沒有 gstreamer）中使用相同的 rtsp 地址可以正常工作。

測試時使用此管道：

GST_DEBUG=1 gst-launch-1.0 -v rtspsrc location=rtsp://admin:password$@192.168.2.1:554/ch1/main/av_stream ! decodebin ! autovideosink

運行管道時出現此錯誤：

Pipeline is live and does not need PREROLL ...

如果我使用的密碼不正確，我也會收到相同的錯誤消息。 這讓我相信 gstreamer 無法登錄到 ip 攝像頭視頻流。

出於跟蹤和錯誤的目的，我在沒有 usr 或密碼的情況下嘗試了此管道：

GST_DEBUG=1 gst-launch-1.0 -v rtspsrc location=rtsp://192.168.2.1:554/ch1/main/av_stream ! decodebin ! autovideosink

Answer 1

rtspsrc具有用於身份驗證的屬性。

嘗試使用

gst-launch-1.0 -v rtspsrc user-id=admin user-pw=password location=rtsp://192.168.2.1:554/ch1/main/av_stream ! decodebin ! autovideosink
