The source code of the playback system for the recordings of IETF meeting sessions was recently released by Meetecho under an open source license, and the IETF has now deployed its own instance of the system, which will be used to share recordings of IETF 121 Dublin to be held 2-8 November 2024. It can also be used to watch recordings of past IETF meetings, from IETF 98 onward.
