REGRESSION (271946@main): Netflix playback stops with error S7361-1253 once a
renewing content key request is made
https://bugs.webkit.org/show_bug.cgi?id=267001
rdar://120230860
Reviewed by Eric Carlson.
To work around a behavior change in certain configurations of
AVContentKeySession, 271946@main
changed the logic for handling content key renewal requests such that the
renewing key request is
looked up by identifier rather than by object identity. This change did not
account for renewing
requests containing multiple AVContentKeyRequests, breaking encrypted playback
on netflix.com once a
renewing request is made several minutes into playback.
Fixed this by checking each of the request's AVContentKeyRequests for a
matching identifier rather
than just the first one.
