QMediaPlayer has bad image's quality
-
Hello!
Quality of image in QMediaPlayer is worse than in a standard media player.
Example:
QMediaPlayer - http://i63.fastpic.ru/big/2014/1009/9f/3301e3e57e94dcf716b72b1ed699f89f.png
Media Player Classic - http://i63.fastpic.ru/big/2014/1009/ec/a2e923bdd4f8d3f419e1cf6de78df2ec.png -
Hi and welcome to devnet,
The images doesn't seem accessible.
So, what OS/Qt/compiler combo are you using to run your application ?
-
I meant that image's quality of video streaming by QVideoWidget or QGraphicsVideoItem has bad quality.
Windows 7 Professional SP1 x64 / Qt 5.3 / MinGW 4.8.2 32bit
-
That I understood. However if you could repost the picture so to see how exactly they are worse would help.
-
I've attached 2 links to images in the first post. There must be parts of images with digit combination 01 - (56) - 814. What's wrong with these links?
-
Well, the site is cluttered with publicity and I'm not fluent in Russian so I don't know if I should click somewhere to see the image or if they should already be visible.
