Slow response in N78 & N80, after capturing video.

Hi all,

I want to do video capturing.
I have done it as follows:
staring the recorder, by setting the record location of the VideoControl to the handset memory. when the user stops recording i am doing :
recordControl.stopRecord();
recordControl.commit();
videoPlayer.stop();
videoPlayer.close();

& then i am displaying a list of option to the user to play it and so..

my code is error free & its working in E51 & some others properly but same code in Nokia N78 & Nokia N80, when i click on "Stop" button however the video recording stops & it stays for a long time in that still screen.
initially i thought its not listening to the stop command. but its not the case, once i recorded small(say 5second)file & when i clicked stop, i waited for a long time for 30 - 50 sec, then the list screen displayed. so according to this, i think its taking long time to display that screen. can nybody tell me anything i can do so that the response will get better.
thanks in advance,
chetan.

I cannot remember any known issues.

I would suggest you to debug the code a little more or to post relevant pieces of your code so others could contribute.

thanks for the reply hartti,
here is some part of the code which may help others to solve the problem:

/// for recoording video:
private void captureVideo() {
try {
videoPlayer = Manager.createPlayer("capture://video");
videoPlayer.realize();


videoControl = (VideoControl) videoPlayer.getControl("VideoControl");
Canvas canvas = new VideoCanvas(Meomyo.mMidlet, videoControl);
canvas.addCommand(cmdCaptureStop);
canvas.setCommandListener(this);
display.setCurrent(canvas);

recordControl = (RecordControl) videoPlayer.getControl("javax.microedition.media.control.RecordControl");
if (recordControl == null) {
throw new Exception("No RecordControl available");
}

FileConnection filecon = (FileConnection) Connector.open(mainVideoDirectoryPath + fileName);
if (!filecon.exists()) {
filecon.create();
}

recordControl.setRecordLocation(mainVideoDirectoryPath + fileName);
videoPlayer.start();
recordControl.startRecord();

} catch (Exception e) {
}

}

// in commandAction():

if (cmd == cmdCaptureStop) {
try {
recordControl.stopRecord();
recordControl.commit();
videoPlayer.stop();
videoPlayer.close();
showCaptureDoneForm();


} catch (Exception e) {
}


where:
* VideoCanvas is a Canvas used to display the video
* mainVideoDirectoryPath is either phone-video folder path or memory card-video folder path
* showCaptureDoneForm() is a method to display the list of options.

As i have already told the code is workin fine n only in nokia N80 & N78 its so late in response(that is ths list of options is displayed very late).

thanks once again,
chetan

During a quick glance I did not see anything wrong with your code...hmmm. am I missing something?

Does the amount of time before showing the options vary based on the recording length?
Without the recording, does the options show immediately?

Hartti

s hartti, it is varying with the duration of the clip that i capture, longer the clip longer the delay. but i couldn't test "without recording" thing b'cas even i stop imediately, some clip would have captured & writen, however at that time it shows the option menu quicker.

more details:
the location given is memory card,(1GB) & i don't think the phone may go slow because of that as most of the memory is free & also other operations(other than my app) go normally. & i also tried giving phone memory location , but no changes.

Or not, as you mention that using phone memory does not change a thing.
Hmmm...

Hartti

hi all,
i still dint get the solution for this,
i used form instead of Canvas,
i did stop,close n commit after i displayed the option screen..
n so on...
but no use,
please anybody give me some more suggestions so that i can try it on..
thanks,
chetan.
