ffmpeg輸入rtsp錯誤

我打過url rtsp：// admin：admin @ camera -ip：4455成功從相機鏈接。但是當我通過ffmpeg得到它。ffmpeg輸入rtsp錯誤

ffmpeg -i rtsp://admin:[email protected]:4455 -codec copy -f rtmp:/streaming-ip:1935/RTMP/test

我得到錯誤：

的原因是什麼？我能做些什麼來解決這個問題。

感謝您的幫助。

在'-i'之前加'-analyzeduration 20M -probesize 20M'並查看。 – Mulvya

感謝您的幫助，但它不起作用。我認爲原因是rtsp：// admin：admin @ camera-ip：4446：操作不允許，但我不知道爲什麼。再次感謝。 –

看起來您正試圖將RTSP流轉換爲RTMP。爲了將你的問題分成小塊，我建議確認你能夠成功接收RTSP流，一旦你確認你可以嘗試將它轉換成RTMP。

使用ffplay，您可以驗證ffmpeg是否可以正確接收RTSP流。您也可以使用Wireshark捕獲RTSP通信。

RTMP使用1935端口，請確保您有權在該端口上打開TCP套接字。使用sudo以防萬一。希望這可以幫助。
