Back in 2019, we set upon replacing our aging transcoding pipeline. We’re in 2023 and the old system still hasn’t been deprecated. What is taking us so long? In this talk, we’ll go over why we decided to build a new transcoding platform (goals, why not just improve the existing one, etc.), the challenges we faced (video, infrastructure or otherwise), how it (carefully) got rolled out to our users, and some lessons learned along the way. This talk was presented at Demuxed ’23, a conference for video nerds in San Francisco featuring amazing talks like this one.
