Gifs optimization using Qt on imx6ull

kwroot — Wed, 02 Sep 2020 13:06:11 GMT

Hello,

I have to reproduce a Gif in loop mode but i'm facing a problem: when the Gif is up and running the cpu usage goes to 80%.

The follow snippet of code shows the implementation details:

QMovie *movie = new QMovie(":path.gif"); QLabel *pLabel = new QLabel(this); pLabel->setMovie(movie); movie->start();

I'm wondering if there is a problem of graphics optimization or the imx6ull (running Linux compiled with Yocto-Release sumo) is not suited for handle this works load.

Gif specs:

Resolution: 480x800 (same as display size)
Frame Rate: 25 fps
Dimension: 300kb

Thank you in advance!

EDIT:

the snippet of code is the follow:

QMovie *movie = new QMovie(":path.gif"); movie->setCacheMode(QMovie::CacheAll); QLabel *pLabel = new QLabel(this); pLabel->setMovie(movie); movie->start();

Hello kwroot,

The MX6ULL do not have GPU, QT will work on a CPU and will take time processing this images.
