            Bug ID: 254498
           Summary: [MSE] SourceBufferPrivate and SourceBufferParser
                    should operate in the content process.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jean-yves.avenard at apple.com

Currently, the SourceBufferPrivate and its SourceBufferParser lives in the GPU Process.
This requires extensive back and forth operations between the content and GPU Process, including playing trick so that the MediaSamples that are processed in the GPU Process be owned by the content process.

The reasons the SourceBufferPrivate was moved to the GPU Process were historical in that the encryption data if the content was encrypted had to live in the same it was created and played.

There are new APIs that remove this restriction.
