Barcelona video tech meetup November 2022: Delivering reliable live streaming over unreliable backbone networks

Abstract Sometimes we need to deliver a highly reliable live streaming experience over a network that is not designed for that. At Meta we implemented a flexible multi-path strategy that allowed us to fix (almost) all problems (buffering and disconnections) caused by unavoidable network events. PS: Very similar talk than Video@scale 2022 See meetup link

SF Video March 2022: RTMP GoAway (at Meta): What is it? How can I implement it and test it?

Abstract At Meta we implemented RTMP Go Away, this is a new mechanism that allows the live RTMP server to send a signal to the client indicating that it needs to reconnect. This allows the client to create a new connection at a logical media boundary, incurring zero data loss in your live streams. ThisContinue reading “SF Video March 2022: RTMP GoAway (at Meta): What is it? How can I implement it and test it?”

SF Video May CO-Video 2021 (Global Video Tech Meetup): Live distributed encoding proof of concept based on AWS Lambdas

Abstract In this talk I showed a system that allows you to stream SRT (h264 + AAC) and create the live ABR in a fully distributed way. This implementation uses AWS Lambdas to perform a segmented serverless transcoding, this allow us to instantly scale to any type of renditions and transcoding settings, tested up toContinue reading “SF Video May CO-Video 2021 (Global Video Tech Meetup): Live distributed encoding proof of concept based on AWS Lambdas”

SF Video Tech meetup: Build your own low latency live platform

Transitioning Broadcast to Cloud

Abstract We analyze the differences between on-premise broadcast and cloud-based online video delivery workflows and identify technologies needed for bridging the gaps between them. Specifically, we note differences in ingest protocols, media formats, signal-processing chains, codec constraints, metadata, transport formats, delays, and means for implementing operations such as ad-splicing, redundancy and synchronization. To bridge theContinue reading “Transitioning Broadcast to Cloud”

MMSYS 2019 keynote: Live streaming at scale

Abstract Livestreaming could be quite challenging, mainly because nowadays OTT is replacing typical linear TV solutions (cable, satellite, and OTA), and the viewers expects at least the same level of quality, reliability an features as before. The big challenge of OTT is to achieve that same UX using, most of the cases, technologies that areContinue reading “MMSYS 2019 keynote: Live streaming at scale”
