Forward error correction (FEC) is a seemingly simple idea when the sender adds redundant data during transmission for the receiver to be able to recover from packet loss.
This talk covers challenges faced when implementing FEC for RTP media in the GStreamer eco system; ranging from an architectural discussion on how to implement support for standards such as ULPFEC and Flux FEC (used in WebRTC) and integrate it with GstRtpBin, down to interesting aspects of the Reed Solomon algorithm (used in Skype).
Mikhail Fludkov is originally from a small Siberian town, Bratsk. He graduated from Saint-Petersburg State Polytechnic University with a masters degree in computer science. Worked on H.264 & H.265 codecs in Vanguard Software Solutions, in Saint Petersburg. 3 years ago moved to Oslo after joining Pexip where got acquainted with GStreamer framework for the first time. Worked on GStreamer elements supporting various standards for Forward Error Correction and on network resilience in general. Participated in porting Pexip media stack from GStreamer 0.10 to GStreamer 1.x. In his free time bakes sourdough bread and plays computer games.
Erlend Graff is a software engineer with an MSc degree in computer science from the University of Tromsø, Norway. He currently works for Pexip, where he's been having fun with various video conferencing related technologies for more than two years.
