Andy Francis - When IDR Frame Insertion Backfires

Inserting IDR Frames into live streams helps enable clean, seamless transitions when adaptive bitrate streams switch renditions and reduces artifacts that can be introduced by camera switches in a multi-cam production. It can also help provide clean break points for ad insertion and cover slates and in general would be considered a best practice in most of the cases mentioned above. But sometimes, things take an unexpected turn and a best practice turns out to be the root cause of an issue. In this talk, I'll cover 2 very different live stream workflows and incidents where IDR frame insertion caused problems and what could have been done to avoid issues.
This talk was presented at Demuxed '23, a conference for video nerds in San Francisco featuring amazing talks like this one.
