Amazon Kinesis Video Streams makes it easy to securely stream video from connected devices to AWS for analytics, machine learning (ML), and other processing.
The Amazon Kinesis Video Streams Producer SDK Java makes it easy to build an on-device application that securely connects to a video stream, and reliably publishes video and other media data to Kinesis Video Streams. It takes care of all the underlying tasks required to package the frames and fragments generated by the device's media pipeline. The SDK also handles stream creation, token rotation for secure and uninterrupted streaming, processing acknowledgements returned by Kinesis Video Streams, and other tasks.

- You can find available pre-built KinesisVideoProducerJNI library in src/main/resources/lib/ for Mac (x64), Ubuntu (x64) and Raspian (x86) and Windows 10. If pre-built libraries did not work for you, "KinesisVideoProducerJNI" native library needs to be built first before running the Java demo application. Please follow the steps in the section Build the native library (KinesisVideoProducerJNI) to run Java Demo App in Producer SDK CPP readme.
Import the Maven project to your IDE, it will find dependency packages from Maven and build.
Run DemoAppMain.java in ./src/main/demo with JVM arguments set to
-Daws.accessKeyId=<YourAwsAccessKey> -Daws.secretKey=<YourAwsSecretKey> -Dkvs-stream=<YourKinesisVideoStreamName> -Djava.library.path=<NativeLibraryPath> -Dlog4j.configurationFile=log4j2.xml
for non-temporary AWS credential.
-Daws.accessKeyId=<YourAwsAccessKey> -Daws.secretKey=<YourAwsSecretKey> -Daws.sessionToken=<YourAwsSessionToken> -Dkvs-stream=<YourKinesisVideoStreamName> -Djava.library.path=<NativeLibraryPath> -Dlog4j.configurationFile=log4j2.xml
for temporary AWS credential.
Note: NativeLibraryPath must contain your "KinesisVideoProducerJNI" library. File name depends on your Operating System:
libKinesisVideoProducerJNI.sofor LinuxlibKinesisVideoProducerJNI.dylibfor Mac OSKinesisVideoProducerJNI.dllfor Windows
If you are using pre-built libraries, please specify the path of library. Take pre-build library for Mac as example, you can specify src/resources/lib/mac as .
Demo app will start running and putting sample video frames in a loop into Kinesis Video Streams. You can change your stream settings in DemoAppMain.java before you run the app.
If you want to run the DemoAppMain, follow the steps below. See Prerequisites to find available native library needed to run DemoAppMain.
Change the current working directory to
$ cd /<YOUR_FOLDER_PATH_WHERE_SDK_IS_DOWNLOADED>/amazon-kinesis-video-streams-producer-sdk-java/
Compile and assemble Java SDK, Java Demoapp and the Maven dependencies
$ mvn clean compile assembly:single
Start the demo app
$ java -classpath target/amazon-kinesis-video-streams-producer-sdk-java-1.12.1-jar-with-dependencies.jar -Daws.accessKeyId=<ACCESS_KEY> -Daws.secretKey=<SECRET_KEY> -Dkvs-stream=<KINESIS_VIDEO_STREAM_NAME> -Djava.library.path=<NativeLibraryPath> -Dlog4j.configurationFile=log4j2.xml com.amazonaws.kinesisvideo.demoapp.DemoAppMain
$ mvn clean test -DargLine="-Daws.accessKeyId=<YourAwsAccessKey> -Daws.secretKey=<YourAwsSecretKey> -Daws.sessionToken=<YourAwsSessionToken> -Djava.library.path=<NativeLibraryPath> -Dlog4j.configurationFile=log4j2.xml"
Refer the README.md file in the dockerscripts folder for running the build and demo app within Docker container.
Run PutMediaDemo.java to send sample mkv stream to Kinesis Video Streams. Note: ACCESS_KEY, SECRET_KEY, and a KINESIS_VIDEO_STREAM are required for running this sample application as well. However, this demo application does not require JNI.
-Daws.accessKeyId=<YourAwsAccessKey> -Daws.secretKey=<YourAwsSecretKey> -Dkvs-stream=<YourKinesisVideoStreamName>
for non-temporary AWS credential.
-Daws.accessKeyId=<YourAwsAccessKey> -Daws.secretKey=<YourAwsSecretKey> -Daws.sessionToken=<YourAwsSessionToken> -Dkvs-stream=<YourKinesisVideoStreamName>
- Mac OS X (El capitan 10.11 or above)
- Ubuntu (14.04 or above)
- Raspian (9 stretch or above)
For additional examples on using Kinesis Video Streams Java SDK and Kinesis Video Streams Parsing Library refer:
If you notice error in loading the native library (JNI), then check the output of ldd or otool
$ ldd libKinesisVideoProducerJNI.so
or in MacOS
$ otool -L libKinesisVideoProducerJNI.dylib
This will provide details on missing libraries during linking; If the output shows missing shared libraries, then run the following commands to link:
Run the following from the build directory in CPP producer SDK:
cmake .. -DBUILD_JNI=TRUE
make
Then, provide the path to the libKinesisVideoProducerJNI.dylib library.
This should resolve native library loading issues.
The repository is using develop branch as the aggregation and all of the feature development is done in appropriate feature branches. The PRs (Pull Requests) are cut on a feature branch and once approved with all the checks passed they can be merged by a click of a button on the PR tool. The master branch should always be build-able and all the tests should be passing. We are welcoming any contribution to the code base. The master branch contains our most recent release cycle from develop.

- Updating the name and description of Java SDK to publish in maven
- Added support for uploading files(offline mode) to Kinesis Video Stream
- Additional fixes
- Remove streamName parameter from KinesisVideoClient.registerMediaSource() as MediaSource already has the stream name in StreamInfo.
- Add KinesisVideoClient.unregisterMediaSource() to remove MediaSource to KinesisVideoProducerStream binding from KinesisVideoClient. Customers can use unregisterMediaSource() after they stop streaming, so MediaSource data will not to be sent to Kinesis Video Streams.
- Add getStreamInfo() to MediaSource instead of MediaSourceConfiguration. If customers have implemented their own MediaSource and MediaSourceConfiguration, they would need to provide stream information via MediaSource.getStreamInfo(). The MediaSourceConfiguration.getStreamInfo() will not work.
