Re: [Maemo 5] Keeping record of last two minute video recording?

let's start garage project for this, I can't wait to post commits :)
Or some git*

Re: [Maemo 5] Keeping record of last two minute video recording?

But 3 seconds are lost on each video.

Re: [Maemo 5] Keeping record of last two minute video recording?

Maybe let's talk on #maemo@freenode?

Great start :)
Just move STATE_PLAYING into while loop and fix prints, please :)

I fixed that.

Code:

chmod 755 record.py; ./record.py

record.py:

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)



    # 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")

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

i opened leafpad and paste your code and save it as record.py(in /home/user)

than i try to run it but first permission denied and import not found

so i sudo gainroot and than run it but still import not found

there are screen shot for you thanks in advance!

Re: [Maemo 5] Keeping record of last two minute video recording?

Oops, add

Code:

#!/usr/bin/env python

to the beginning of that file.

speacial Thanks to skykooler and int_ua

Re: [Solved] [Maemo 5] Keeping record of last two minute video recording?

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 :)
