Video size 640x480?

[richardkrieger]

German:

Hallo,

ich nutze ziemlich oft kurze Filme. Da es im System keine Möglichkeit gibt Videos abzuspielen, haben wir WebcamMax im Einsatz.

Über die vom WebcamMax erzeugte virtuelle Camera spielen wir die Videos ab - klappt wunderbar, ABER: beim Video werden die Seiten abgeschnitten, wie Sie hier sehen können:

Das ist ein 640x480 Standard-Video. Den effekt beobachtete ich in allen Versionen bis 1.8.3(habe die noch nicht getestet, vermute aber, dass es genauso aussehen wird).

Woran könnte das liegen?

##############################

По-русски:

Здравствуйте,

я использую для презентаций короткие фильмы. Так как в системе нет специальной возможности для прокрутки ролика, мы используем программу WebcamMax. Через виртуальную Webcam от WebcamMax можно прогнать ролик.

Эта комбинация работает, но есть одно НО: OpenMeetings подрезает стороны видео, как Вы можете увидеть здесь:

Это стандартное 640x480 видео. Это эффект я наблюдал во всех версиях до 1.8.3(еще не проверил но думаю, что будет выглядеть так же)

Что можно было бы сделать для исправления ошибки?

Hallo Richard,

we are an english speaking group, no German no Russian :)

I think you might try to resize your video pod and then try to -republish the stream (with different width/height of the video pod).
You can republish the stream by click the *sync* icon in your own video pod or in the user list and the device settings will popup again.

Your effect is the result of the video width/height settings, the application broadcasts the stream with the width/height of the actual video pod.
If you want to publish with 640x480:
Resize the your video pod to 640x480
Click the Sync icon
Republish with the new video pod sizes

... you might see big changes in the needed bandwidth of course.

google-translation from german:

second try:

Player:

before sync:

after sync:

Room Type: conference

[seba....@gmail.com]

yeah,

you should try to resize the webcam to 640x480 and not 480x480 before you re-sync / re-publishing the video stream.
Or in other words: Resize to ratio of 4:3 instead of 1:1 before re-syncing / re-publishing the video stream.

google translation:

This is a 640x480 video. I can not make to 480x480, this possibility has not at the software.

Or do you mean configuration in "openmeetings"? I found nothing except config.xml. There I can only change quality. There any other way?

've Found: "restricted" room cuts off just right and the left. "conference" room also cuts off the top and bottom.

[seba....@gmail.com]

No,

I meant to resize the video pod to 640x480 not the webcam.

where can I do that?

SOAP calls "addRoom" and "updateRoom" are deprecated. Did it with "updateRoom" tried - VideoPod is not changed. New calls ("updateRoomWithModeration") no longer have the parameters for videopod.

Or do you mean simply drag the mouse videopod bigger? So I can not change the ratio. It remains at 1:1

[seba....@gmail.com]

yes I mean to drag the video pod bigger to 4:3 ratio and then re-publish the stream

even if I set it to 320x240 video. And videopod draw on the entire screen surface.

it is still cut off on the right and left.

Let's try something else: the source code where I can find it?

[seba....@gmail.com]

for example: http://code.google.com/p/openmeetings/source/browse/trunk/singlewebapp/WebContent/openmeetings/base/remote/baseVideoStream.lzx

what is result of "$once(4/3)" ?

what does this function?

[seba....@gmail.com]

where do you see this code? The code makes not so much sense to me.

.. but it might be a good idea for the future to make a default 4:3 setting available.
I think we had already some modification where you could choose from the device settings box the default size of the video pod.

if you could wait for some days I can checkin some code into trunk to edit the video pod size before publishing the video. Then you could rerun your test again.

OK thank you
