            Bug ID: 245081
           Summary: [MSE] Round SourceBuffer removal range
           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

Representation of removal times as double in SourceBuffer::remove() can cause problems in HBOMax due to precision/rounding problems.

In some problematic cases an unintended frame would be marked for removal because of the very small overlap that could come from precision lost. For instance, HBOMax uses the PTS of the next sample as removal 'end' and unexpectedly removes the next segment (as it's a sync frame) sometimes.

Rounding the double removal range delimiters to nanoseconds would help to avoid those problematic cases.
