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);@

MrNoway

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
