[Moved] cannot play audio on n9 with QML component SoundEffect or Audio

[lemonlinger]

I am developing an app with QML on N9. And I wanna play some sound effects and background music. So I use QML components SoundEffect and Audio. It works normally running on simulator, but fails on N9 device. I have add mobility into my pro file as follows:

CONFIG += qdeclarative-boostable mobility
MOBILITY += multimedia

I got some information from compile output:

aegis-installing wordmatch (from '')
Package wordmatch: denied 'GRP::audio' -- origin '' does not allow it
Package wordmatch: denied 'GRP::audio' for '/opt/WordMatch/bin/WordMatch' -- origin '' does not allow it
Package wordmatch: denied 'GRP::audio' for 'applauncherd-launcher::/usr/bin/applauncherd.bin' -- origin '' does not allow it

But i can't figure it out.
Did anybody come up against this problem? Plz help me, Thanks~

Ps: The source of SoundEffect & Audio is from local audio files, like mp3.

Hi,

Have you added the required tokens to manifest.aegis file that is in the qtc_packaging/debian folder?

Please check this link for the tokens that have to be present depending on the components used.

QtMobility Multimedia
GRP:ulse-access
GRP::video

hi kusumk, thanks. I have added mobility module into my pro file. So qmake can automatically generate a .aegis file with the following content:

<aegis>
	<request policy="add">
		<!-- Application uses QtDeclarative module. -->

		<!-- import QtMultimediaKit 1.1 -->
		<credential name="GRP::audio" />
		<credential name="GRP::pulse-access" />
		<credential name="GRP::video" />

		<for path="/opt/WordMatch/bin/WordMatch" />
		<for path="applauncherd-launcher::/usr/bin/applauncherd.bin" id="" />
	</request>
</aegis

So I think it's not the point of the problem.

Hi,

I tested the above harmattanapishowcase application,
soundeffect sample. It works with .wav file.

When i used an .mp3 that works with the device music player, it does not work with SoundEffect

some codec error shown in qtcreator as - QSoundEffect(pulseaudio): Error decoding source

So some of .mp3 are not supported in N9. It seems to work for some though with different mp3 files. See this thread

Similar problem is observed and a workaround is provided here.
