BeagleBoard/GSoC/2020 Projects/Media IP Streaming
This project will equip the Beagleboard AI with Media IP Streaming capabilities, by porting the sound card drivers for CTAG face2|4 Audio Card to the Beaglebone AI. Additionally the AVB protocol stack is ported from Beagle Bone AVB to the Beaglebone AI.
This project is currently just a proposal.
All requirements have been fullfilled, the Pull Request can be found here #139
School: Kiel University of Applied Sciences
Primary languages: German, English
Typical work hours: 8AM-5PM CET
Previous GSoC participation: I want to participate at GSoC because I want to gather experience in working within an open source community and try to apply theoretical knowledge into the practical domain. Also I hope to learn new awesome things. This would be my first time participating in GSoC.
About your project
Project name: Media Ip Streaming
The BeagleBone AI is equipped with a high amount of processing power due to the Dual Core ARM Cortex-A15 chip as a main computing unit and accompanying co-processors. This makes the AI a perfect fit for highly demanding applications regarding CPU consumption, like audio applications which have extremely strong realtime constraints. Professional audio/video studios have to guarantee for small latencies when transmitting media signals between different devices and different media channels in a transmitted stream need to be synchronized. Latency and Snychronicity is extremely important when transmitting e.g. a video channel together with the accompanying audio channel. Those two channels have to be transmitted in a manner, that lip synchronicity can be guaranteed because humans are extremely sensitive to voice offset to accompanying video signals.
To bring media ip streaming capabilities to the Beaglebone AI, the following steps are planned: A previous GSoC project ported a sound card driver from the BeagleBone Green/Black to the BeagleBoard-X15 (https://summerofcode.withgoogle.com/archive/2016/projects/5351212496977920/). This port will now be ported to the BegleBone AI. With the sound card driver successfully ported, the next step would be to port the AVB protocol driver stack from Beagle Bone AVB enabling media streaming over the network. This would allow to use the Beaglebone AI as a media streaming device in professional audio/media applications and bring audio stream synchronisation features to the Beaglebone AI. Thus allowing for tight synchronization between different audio and video streams which are transmitted over the network.
Provide a development timeline with a milestone each of the 11 weeks and any pre-work. (A realistic timeline is critical to our selection process.)

Experience and approach
During my bachelor's degree in information technology I had several courses like programming in c, programming in c++, operating systems and embedded system programming which layed down the basis for developing embedded software. Due to my additional bachelor's degree in audio production I have additional experience in audio applications and audio and media codecs, which will help me to understand the theory behind the different needed algorithms. With my previous development work for the Strämpler project I already have experience in working on complex embedded c projects and which potential pitfalls could occur.
If I get stuck and my mentor is not around I will follow the following steps in displayed order:
- Search the internet for the problem.
- Serach through literature acquired during milestone #1.
- Ask in the GSoC IRC, if fellow students know a solution to the specific problem.
- If the problem is still not solved, postpone the problem until mentor is available again and work on another part of the project.
Equipping the Beaglebone AI with media ip streaming capabilities would allow the Beaglebone.org community to use those capabilities to implement the system in professional media applications. The community could also implement further media protocols like AES/Ravenna to allow the usage of the AI for even more media streaming tasks.
