Error playing Freeview recorded files after server upgrade. "Invalid decoder type 'aac_latm'"

Server Version#: 1.43.0.10231
Player Version#: Plex Web 4.152.0

After a recent upgrade I can no longer play recordings from my server on the web client or the LG WebOS client. The server logs show errors that appear to be related to transcoding.

[Req#346e0e/Transcode/qseferv6o9qhwrtsyzolz7vf/709c9315-a4d0-42e2-8310-570f195a3782] Invalid decoder type ‘aac_latm’

The transcode command from the logs is

For anyone stumbling upon this, downgrading to server version 1.42.2.10156 solved the issue. I guess that aac_latm hasn’t made it into the new transcoder yet.
