"""The server CDM must license every WRM header a track carries, not only the first.
|
|
|
|
A track can hold one `PlayReady` object per header: `ISM` shares a Protection list, `HLS`
|
|
emits one per `EXT-X-KEY`. `extract_pssh_from_track` returns the first PSSH only, so the
|
|
server folds in the siblings. Without that it returns fewer content keys than a local CDM.
