我想從我的網路攝像頭流式傳輸到 Kinesis Video Streams。我一直在閱讀檔案并遵循 AWS教程。使用以下命令啟動 DemoAppMain 后：
java -classpath target/amazon-kinesis-video-streams-producer-sdk-java-1.11.0-jar-with-dependencies.jar "-Daws.accessKeyId=fake_accessKeyID -Daws.secretKey=fake_secretKey -Dkvs-stream=fake_streamName - Djava.library.path=src\main\resources\lib\windows\KinesisVideoProducerJNI.dll" com.amazonaws.kinesisvideo.demoapp.DemoAppMain
我得到以下例外：
DEBUG / KinesisVideo: Unsatisfied link error. Directly loading native library .so.
DEBUG / KinesisVideo: Unsatisfied link error. Directly loading native library .dylib.
DEBUG / KinesisVideo: Unsatisfied link error. Directly loading native library .dll.

我在互聯網上做了研究，但沒有成功。這就是我發這個帖子的原因。如果有人知道如何解決這個問題，我將不勝感激！
uj5u.com熱心網友回復：
錯誤指出：
no KinesisVideoProducerJNI in java.library.path
你是如何將這個庫添加到你的類路徑中的？
檔案說明了擁有此庫的先決條件：
Your NativeLibraryPath must contain your KinesisVideoProducerJNI file, available at https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp
. The file name extension for this file depends on your operating system:
KinesisVideoProducerJNI.so for Linux
KinesisVideoProducerJNI.dylib for macOS
KinesisVideoProducerJNI.dll for Windows
如果您查看 windows 檔案夾，則該庫存在于那里：
https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-java/tree/master/src/main/resources/lib/windows
也許這樣做會奏效：
-Djava.library.path=src/main/resources/lib/windows <-- The Directory!
java -classpath target/amazon-kinesis-video-streams-producer-sdk-java-1.11.0-jar-with-dependencies.jar -Daws.accessKeyId=<ACCESS_KEY> -Daws.secretKey=<SECRET_KEY> -Dkvs-stream =<KINESIS_VIDEO_STREAM_NAME> -Djava.library.path=src/main/resources/lib/windows com.amazonaws.kinesisvideo.demoapp.DemoAppMain
