           Summary: [Texmap] Add support to upload more color formats into
                    the texture
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: vjaquez at igalia.com

Right now the the GStreamer video sink supports BGRx and BGRA and the normal code path is to upload the buffer into a texture subimage. 

Nevertheless the BGRx support is broken when the padding value comes with 0x00 or random values (which are valid), the texture needs to be 0xff. Probably we would need a shader to fix this.

If so, it would make sense to support the upload of other color formats (with more planes), such as yuv or nv12.
