In the Intel AVBStreamHandler repository, several files are responsible for handling AVB packet generation. The primary components involved in generating and transmitting AVB packets are typically spread across files that manage stream configuration, packet construction, and network transmission.
Key files to look at for AVB packet generation include:
AvbStream.cpp
AvbPacket.cpp
AvbEthernet.cpp
AvbStreamHandler.cpp
AvtpAudio.cpp
and AvtpVideo.cpp
Avtp.cpp
AvbTsnStream.cpp
The primary files responsible for AVB packet generation in the Intel AVBStreamHandler project are:
AvbStream.cpp
: Manages stream setup and controls packet generation.AvbPacket.cpp
: Handles the actual construction of AVB packets.AvbEthernet.cpp
: Manages Ethernet-level transmission of AVB packets.AvbStreamHandler.cpp
: Coordinates stream operations and packet handling.AvtpAudio.cpp
/ AvtpVideo.cpp
: Format audio and video AVTP packets.Avtp.cpp
: Manages AVTP packet headers and encapsulation.AvbTsnStream.cpp
: Manages TSN aspects of stream timing and scheduling (optional for AVB).To dive deeper, examine the packet construction functions within AvbPacket.cpp
and related header creation code in Avtp.cpp
and AvtpAudio.cpp
or AvtpVideo.cpp
, depending on the stream type.
Here are the mentioned files along with their relative paths within the Intel AVBStreamHandler repository:
AvbStream.cpp
private/src/avb_streamhandler/src/AvbStream.cpp
AvbPacket.cpp
private/src/avb_streamhandler/src/AvbPacket.cpp
AvbEthernet.cpp
private/src/avb_streamhandler/src/AvbEthernet.cpp
AvbStreamHandler.cpp
private/src/avb_streamhandler/src/AvbStreamHandler.cpp
AvtpAudio.cpp
private/src/avb_streamhandler/src/avtp/AvtpAudio.cpp
AvtpVideo.cpp
private/src/avb_streamhandler/src/avtp/AvtpVideo.cpp
Avtp.cpp
private/src/avb_streamhandler/src/avtp/Avtp.cpp
AvbTsnStream.cpp
private/src/avb_streamhandler/src/tsn/AvbTsnStream.cpp
These files contain the logic for handling AVB packet generation, media stream encapsulation, and Ethernet-level transmission within the AVB/TSN framework. You can explore these paths in the Intel AVBStreamHandler repository to dive deeper into each file's functionality.
In the Intel AVBStreamHandler repository, audio and video stream handling is mainly managed through specific files that deal with the encapsulation and transmission of audio and video data. Here are the files responsible for handling audio and video streams:
AvtpAudio.cpp

AvbStream.cpp
private/src/avb_streamhandler/src/AvbStream.cpp
AvtpVideo.cpp
private/src/avb_streamhandler/src/avtp/AvtpVideo.cpp
AvtpAudio.cpp
, it deals with the correct formatting and transmission of video data over the network.AvbStream.cpp

These files manage the flow, formatting, and transmission of both audio and video streams within the Intel AVBStreamHandler project. Each of these components is crucial for ensuring that AVB-compliant media streams are generated and transmitted across the network in a synchronized and reliable manner.
To effectively reuse code from Intel’s AVBStreamHandler in your project, you’ll want to follow best practices to ensure compatibility, maintainability, and proper integration with your existing codebase. Here’s a structured approach to reusing code from the repository:
Start by identifying the specific functionalities from AVBStreamHandler that are most relevant to your project:
Based on the functionality you identified, the following components are good candidates for reuse:
AvtpAudio.cpp
/ AvtpVideo.cpp
: These files handle audio and video AVTP formatting, which is crucial if your project involves media streaming.AvbStream.cpp
: This file manages stream lifecycle and data flow, useful for handling both audio and video stream operations.AvbPacket.cpp
: This file is essential for AVB packet creation and is key for ensuring your project follows AVB/TSN packet structures.AvbEthernet.cpp
: Provides Ethernet-level interaction for packet transmission over a network.After identifying the relevant code, refactor and isolate the specific modules for easier integration into your project. Here’s how you can do it:
Modularize the Code:
Encapsulation:
Refactor for Compatibility:
Dependencies:
libpcap
, PTP
, or others for network and time synchronization functionality. Integrate them as needed.Licensing:
Unit Testing:
Integration Testing:
After successfully integrating the AVBStreamHandler code into your project, you may need to extend or customize certain features to meet your specific requirements:
Custom Protocol Enhancements:
AvtpVideo.cpp
file to accommodate your custom requirements.Performance Tuning:
Document Your Changes:
Maintain Synchronization:
By following these steps, you can effectively reuse components from Intel’s AVBStreamHandler while ensuring that your project remains maintainable, functional, and legally compliant.
The Intel AVB Stream Handler (AVBSH) is a project that serves as a bridge between AVB-capable Ethernet interfaces (such as Intel i210 NICs) and local audio/video applications. The AVB Stream Handler ensures proper AVB packet generation in line with the IEEE 1722 standard and manages a subset of IEEE 802.1Q protocols relevant for automotive and professional AV applications.
Key Features:
The project is no longer maintained by Intel, meaning there are no future updates, bug fixes, or new releases planned. However, it is open for forking and further development by the community.
You can find more details and explore the project on its GitHub page.
