As they are used to serialise CMSampleBuffer objects over IPC, one of the consequences is that encrypted CMSampleBuffer can't be sent over IPC. We should add support for encryption and also allows conversions of encrypted CMSampleBuffer into a MediaSamplesBlock. 2151590 1 webkit-bug-importer 2025-10-16 02:06:58 -0700 <rdar://problem/162759126> 2151598 2 jean-yves.avenard 2025-10-16 02:50:47 -0700 Pull request: https://github.com/WebKit/WebKit/pull/52462 2154014 3 ews-feeder 2025-10-24 05:51:33 -0700 Committed 302086@main (795999704c17): <https://commits.webkit.org/302086@main> Reviewed commits have been landed.
