          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: frepe at bredband.net

     GNOME version: 2.13/2.14

Please describe the problem:
buffer_alloc is not proxied through tee, this prohibits the use of, for
example, videoscale.

Steps to reproduce:
1. Download the two python scripts attached to this bug report
2. Copy a videofile to /tmp/myvideo.avi
3. Run "python videoscale_works_without_tee.py"
4. Re-size the video window
5. The videostream is properly resized
6. Run "python videoscale_does_not_work_with_tee.py"
7. Re-size the video window
8. The videostream is NOT properly resized


Actual results:
The videostream is not properly resized when a tee element is added to an
otherwise fine-working pipeline.

Expected results:
The videostream should be properly resized regardless of the tee element's
presence.

Does this happen every time?
Yes

Other information:
According to wtay in #gstreamer, this problem is caused by the fact that
buffer_alloc is not proxied through tee.
