VideoWidget Video With Transparent Background

[MrNoway]

I am working on a little game,
and sofar it's going good

I have some short videos and some parts of them are transparent,
basically I am talking about effects like blood, dust, fog, sparkle etc. already prekeyed.

I wanted to use the VideoWidget to show them,
its working if I set up like this, the problem is that the Widget background is not transparent.

It's black.

If I use a label and adding a .gif file, it is transparent,
this is what I want but I cannot use .gif file because the quality is too poor.

@ Phonon::MediaObject *mediaObject = new Phonon::MediaObject(this);
Phonon::VideoWidget *videoWidget = new Phonon::VideoWidget(this);
videoWidget->move(400,300);
videoWidget->resize(500,500);
videoWidget->setWindowOpacity(20);
Phonon::createPath(mediaObject, videoWidget);

Phonon::AudioOutput *audioOutput = new Phonon::AudioOutput(Phonon::VideoCategory, this);
Phonon::createPath(mediaObject, audioOutput);

QString ss2 = "Arrow_01.avi";

mediaObject->setCurrentSource(ss2);
mediaObject->play();@

if I try like this its also not working

@ videoWidget->setAttribute(Qt::WA_TranslucentBackground);
videoWidget->setWindowFlags(Qt::FramelessWindowHint);@

has no one an idea?

Or can you tell me if there are other options to display videos,
using maybe external plugins??

hmm after hours and hours of desperating trying,
I finally figured something out that seems to be a adequate solution.

I converted my visual effect video into a .png sequence.
then I used a normal Widget and set the background image to the first .png file of the sequence.

then I connected a timer to this function and a counter is moving to the next picture.

@ movie_name_int++;
movie_name_string="background-image: url(png_sequence/";
movie_name_string_temp.setNum(movie_name_int);
movie_name_string.append(movie_name_string_temp);
movie_name_string.append(")");
ui.widget_2->setStyleSheet(movie_name_string );@

It works pretty good, but I dont know about the performance, if I am gonna use this often.

anyway
I am happy I can finally continue
Merry Christmas
