Pipeline freezing with Tee to Display and encode

[Robin Aproskie]

Hi Please can someone confirm and help  clarify why this freezes

Thanks
Robin

On Windows 7 "1.2.3"
i7 2.8Ghz CPU

If I run the following pipline It saves the file fine and I can play it using VLC and it diplays without using encoder and using d3dvideosink

gst-launch-1.0.exe videotestsrc ! video/x-raw , format="I420", height=720, width=1280 ! videoconvert !
cairooverlay ! clockoverlay ! tee name = t ! queue ! d3dvideosink t. ! queue ! videoconvert ! video/x-raw, format="I420" ! x264enc ! video/x-h264 ! h264parse ! avimux ! filesink location="c:\\gstreamer\\file.avi" -v

If I put a Tee in, so I can view the video as well it freezes on the first frame which I see.
The cairooverlay is there to simulate my cairo overlay videoformat and changing the caps as it parses through the pipeline.

gst-launch-1.0.exe videotestsrc ! video/x-raw , format="I420", height=720 , width=1280 ! videoconvert !
cairooverlay ! clockoverlay ! tee name = t ! queue ! d3dvideosink t. ! queue ! videoconvert !
video/x-raw, format="I420" ! x264enc ! video/x-h264 ! h264parse ! avimux ! filesink location="c:\\gstreamer\\file.avi" -v

My output is thus
