            Bug ID: 231881
           Summary: overriding RTCVideoDecoderH264/265 color space
                    attachments not always done
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

I found that in some configurations, e.g. builds on Catalina, the "ColorInfoGuessedBy" attachment is not placed on CVPixelBuffers we get from the VTDecompressionSession, but the guessed, incorrect color space attachments are still there. Since we are currently only supporting sRGB color space video streams in WebRTC, we shouldn't check for "ColorInfoGuessedBy", and instead always override the attachments.
