我正在尝试使用 Amazon Kinesis Video Streams 通过 RTSP URL 流式传输闭路电视摄像机。 我已经在 VLC Player 中测试了该 URL，它在那里工作正常。也使用 ffplay 进行了相同的测试。
我使用的命令是这个。
AWS_ACCESS_KEY_ID=myAccessKey AWS_SECRET_ACCESS_KEY=MySecretKey ./kvs_gstreamer_sample CCTVStream rtsp://myrtspUrl但是运行此命令后，我在终端中收到此错误。
我无法理解为什么会发生这种情况。
谁能帮助我理解我在这里做错了什么？
感谢您的帮助

我遇到了这个完全相同的错误，我通过在 RTSP URL 周围添加引号解决了它。
改变
./kvs_gstreamer_sample CCTVStream rtsp://myrtspUrl致
./kvs_gstreamer_sample CCTVStream "rtsp://myrtspUrl"
