there may be several reasons for such a behavior, ranging from an
incorrect clip to wrongly behaving elements in the pipeline.

Some suggestions:

- replace your sink elements with fakesinks and enable gst-launch
verbosity by using its -v option.
- add some identity elements after the tee and set its check-perfect
proerty to "true".

Maybe you can post something here (use pastebin/txt attachments for
more than 10 lines please) after running those tests.
