This is to keep the deprecated VideoReceiver separate from the implementation used by VideoReceiver2 before updating VCMDecoderDatabase to have ownership of the registered decoders. Fixing typo (DataBase->Database) in the name of the remaining class. Bug: webrtc:14486, webrtc:14497 Change-Id: I5ee755921454b0831b3af6d0161f5b48c7c60540 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/276781 Commit-Queue: Tomas Gunnarsson <tommi@webrtc.org> Reviewed-by: Philip Eliasson <philipel@webrtc.org> Cr-Commit-Position: refs/heads/main@{#38247}
