    bin.set_state(gst.STATE_NULL)
    try:
        os.remove("twominutesold.mp4")
    except OSError:
        print "No two-minutes-old file exists yet."
    try:
        os.rename("oneminuteold.mp4", "twominutesold.mp4")
    except OSError:
        print "No one-minute-old file exists yet."
    os.rename("current.mp4", "oneminuteold.mp4")

is there anything which a noob can understand? i dont know what to do i just start xterminal and type

python

(after pressing enter)

should i paste your code (whole code) at once

or i should paste this only.....

Code:

import gst
import time
import os

bin = gst.element_factory_make("camerabin")
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_state(gst.STATE_PLAYING)
    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:
        os.remove("twominutesold.mp4")
    except OSError:
        print "No two-minutes-old file exists yet."
    try:
        os.rename("oneminuteold.mp4", "twominutesold.mp4")
    except OSError:
        print "No one-minute-old file exists yet."
    os.rename("current.mp4", "oneminuteold.mp4")

and what do you mean by saying this...

Code:

chmod 755 record.py; ./record.py

it says no such file or directory

Copy the code I posted into a file called record.py. Then run:

Code:

chmod 755 record.py; ./record.py

Oops, add

Code:

#!/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
