Qt 5.2.0 Beta 1 - iOS - Multimedia

SGaist

Hi,

Did you build the submodule ?

Gianluca

Build !?!? No, I installed the beta 1 from the installer.

How can I add the multimedia submodule to the installed binaries ??

But, why multimedia module has not been installed by the installer ??
It should one of the module provided by default, isn'it ??

SGaist

Then check the content of the installed Qt to see which module have been installed.

I don't know, I didn't use the installer

Gianluca

Some updates.
There is no multimedia module installed by the Qt Installer for 5.2.0 Beta 1
I don't know if this is a mistake, or it was intended because multimedia is not supported yet on iOS.

However, I downloaded the QtMultimedia module, compiled and installed.
After that, the app now is compiling nice, but when running it cannot find any input/output devices ... then If I did everything correctly, there is no multimedia on iOS !!

Someonelse can give me some insight to understand better what's the problem ??

Hello everyone, I would like also to ask you guys if there's any update regarding the qt multimedia library for iOS

I'm looking to intergrate sound effects with low latency, that works under windows but nothing under iOS, even the library itself is always not found

Gianluca

Yes, there are good news !!
Just today I noticed that in the upcoming RC1 there is the multimedia compiled by default and so installed for iOS. They resolved various issues about static plugins and they made a wiki page to explain how to make it works.

I've just downloaded the last snapshot and I'll try it in these days.

q8phantom

oh excellent, thank you, is RC1 released?

Gianluca

No. Probably it will be released next week.

q8phantom

Now, it builds but doesn't work yet, latest 5.2 build for iOS downloaded

using null output device, none available

That's when using QSoundEffect::play

Gianluca

If you follow the instructions on this page
http://qt-project.org/wiki/QtMultimedia_iOS
then file a bug.

q8phantom

no I didn't follow, I'm sorry, though if it's working on windows it should work on iOS

My problem is QTPLUGIN += qtaudio_coreaudio was not added for iOS

q8phantom

Now it is working

q8phantom

Okey, the problem now is the sound is too low to be heared
