Amazon Kinesis Video Streams Producer SDK C/C++

Attention

If you are updating from any release before 1.7.0, you need to specify a track id for each Frame as shown in sample, otherwise you will get a 0x32000026 which means track not found.

Introduction

Amazon Kinesis Video Streams makes it easy to securely stream video from connected devices to AWS for analytics, machine learning (ML), and other processing.

Amazon Kinesis Video Streams Producer SDK for C/C++ 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.

Kinesis Video Streams Producer SDK for C/C++

Amazon Kinesis Video Streams Producer SDK for C/C++ contains the following sub-directories/projects:

kinesis-video-pic - The Platform Independent Codebase which is the basic building block for the C++/Java producer SDK. The project includes multiple sub-projects for each sub-component with unit tests.
kinesis-video-producer - The C++ Producer SDK with unit test.
kinesis-video-c-producer - The C Producer SDK with unit test.
kinesis-video-producer-jni - The C++ wrapper for JNI to expose the functionality to Java/Android.
kinesis-video-gst-demo - C++ GStreamer sample application (for webcam, USB camera and RTSP) .
kinesis-video-gstreamer-plugin - GStreamer plugin sink element (kvssink) and demo application.
kinesis-video-native-build - Native build directory with a build script for Mac OS/Linux/Raspberry PI/Windows. This is the directory that will contain the artifacts (executable binaries) and JNI libraries after the build.
- This should be your current working directory for running the install-scripts.

Kinesis Video Streams Producer SDK was tested on following platforms:

    Ubuntu 16
    Ubuntu 17

- Additional tests and minor compiler warning fixes.
CPP Producer - Updates
- Memory leak fix.
- Minor header include change.
- Test stability fix for RPi.

Kinesis Video GStreamer Plugin version matching SDK version.

Release 2.0.0 (9th Jul 2019)

License update: KVS SDK and GStreamer kvssink plugin are under Apache 2.0 license now.
C-Producer - New feature
- Language level is C89. It should work for all GCC versions, tested minimum GCC version is 4.1.
- The Kinesis Video Streams C producer library wraps kinesis-video-pic (Platform Independent Code) with additional layer of API that allows scenario and platform-specific callbacks and events.
- Callbacks for sample retry logic implementation are now supported through C Producer
CPP Producer - Updates
- Language level is C++11 instead of C++14. Required minimum GCC version is 4.8.
- Kinesis Video Producer CPP (kinesis-video-producer directory) is now revised to a wrapper of C Producer SDK which interfaces with the Platform Independent Repository (PIC, kinesis-video-pic directory).
Platform Independent Code - New functionality
- Automatic CPD (codec private data) extraction from the stream
- Reset stream and reset connection functionality in PIC - In case of unrecoverable errors users can simply call reset stream; internally SDK will free & create the stream.
- Log level supported in PIC. It can be set in member variable of DeviceInfo.ClientInfo.
Platform Independent Code - Bug Fixes
- Skip over error fragments - SDK will continue skip any invalid fragments are ingested through SDK earlier and continue streaming with valid ingested fragments. It will not just loop back and keep resending the broken fragment now.
All unit tests (pic_test, cproducer_test, producer_test) are at C++11 level. Required minimum GCC version is 4.8.
Please note the following changes if you have customized the SDK for your integration and not using samples directly.
- Changes to utility functions:
  - RotatingStaticCredentialProvider is removed from C++ producer. Customer can use StaticCredentialProvider instead.
  - CredentialProviderUtil and SerializedCredentials are removed from C++ producer.
- Following functions are removed from DefaultCallbackProvider: sleepUntilWithTimeCallback, shutdownStream, notifyResult, getControlPlaneUri, safeFreeBuffer, getStreamStatusFromString.
- Changes to the object model:
  - Following attributes have been added: Version number is added to TrackInfo, Frame, StreamDescription, DeviceInfo, StreamInfo.
  - Following attributes have been removed: certPath is removed from DeviceInfo in PIC.

Release 1.1.2 (January 2018)

Allowed devices to output h.264 streams directly
The user can also supply a streaming resolution through command line arguments.
- If resolution is provided then the sample will try to check if the camera supports that resolution. If it does then streaming starts; else, it will fail with an error msg "Resolution not supported"
- If no resolution is specified, the demo will try to use resolutions 1920x1080, 1280x720 and 640x480 in that order (highest resolution first)and will start streaming once the camera supported resolution is detected.
Known issues:
- When streaming on raspberry pi. Some green artifacts might be observed on the preview screen. Reducing the resolution can fix the issue.

Release 1.1.1 (December 2017)

Fix USB webcam support
Known issues:
- If USB webcam doesn't support 720p, then gstreamer negotiation will fail. Trying lower resolution as mentioned in Troubleshooting may fix this issue.
