bin.set_property("videoenc", gst.element_factory_make("dspmp4venc"))
bin.set_property("videomux", gst.element_factory_make("hantromp4mux"))
bin.set_property("audioenc", gst.element_factory_make("nokiaaacenc"))

while True:

    bin.set_property("filename", "current.mp4")
    bin.set_property("mode",1)
    #starts recording
    bin.emit("user-start")

    time.sleep(60)
and then this.........

Code:
    # stops recording
    bin.emit("user-stop")
    bin.set_state(gst.STATE_PAUSED)
    bin.set_state(gst.STATE_NULL)
    try:

Copy the code I posted into a file called record.py. Then run:
Code:
chmod 755 record.py; ./record.py

Oops, add

#!/usr/bin/env python
to the beginning of that file.

I just finished first attempt to get gst-launch working and queue works as expected with this code:
Code:
gst-launch v4l2src device=/dev/video0 ! queue leaky=upstream min-threshold-time=10000000000 ! autovideosink
(time in nanoseconds)
Now it would be great to try to use queue sink in the above python code instead of moving files That's all for today, I hope we will finish it tomorrow
