    @Naveen_D I have had good success with Julius on my Ubuntu Desktop, Raspberry Pi 2 & 3 and embedded Up Board. (intel cpu). Also installed flite (TTS) with several naturally sounding voices. It is for a long range project. My code and notes are at: https://bitbucket.org/andyinyakima/ Look at: boswasi and bos-jt for starters. I use Qt for most of my work. My code ain't pretty but does the trick for me. My first code was assembly on Commodore 64. I saw where Qt 5.9 was released so came to forum looking for QtSpeech updates. Tried Sphinx but couldn't capture well enough, Julius is working good for me. Kaldi is too big I believe. Tried "hello_speak" example on Qt 5.8 on Ubuntu. Get a "can't locate plug_in" error. Does this example work on Linux machines? I am using pulseaudio. Anyhow, will check back to see if any more speech developments being made on Qt. Thank you, andyinyakima

    @Ibrahim you should copy the templates to your project Build Android APK copy templates this copies the templates inside your project in your .pro ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android tells Qt where your android files are living go into this folder, open AndroidManifest and change the default behaviour all is explained there: <!-- The following comment will be replaced upon deployment with default permissions based on the dependencies of the application. Remove the comment if you do not require these default permissions. --> <!-- %%INSERT_PERMISSIONS --> BTW: you should read the documentation: http://doc.qt.io/qtcreator/creator-deploying-android.html scroll down to Editing Manifest Files - there you'll find all the needed informations

    @nitalipa You have to give more information. What's the device/OS you install the app into? What's the Qt version? Etc.

    Hi, My decoded video is rendered by the "QOpenglWidget" and "QOpenGLShader" , my control UI is achieved via QML(QtQuick.Controls 2.1) and rendered by opengl es. When I run my app on Ubuntu 16.04, the error is appeared : EGLFS: OpenGL windows cannot be mixed with others. I have understood that it is the limitations of the egfs , so I have to create only one window for the video and control UI. But how to embed the QML UI to the widget for video ? Qt version : 5.8.0 Environment: Ubuntu 16.04

    @AlterX up to Qt 5.8 something like this will work inside .pro: ios { ..... QMAKE_XCODE_CODE_SIGN_IDENTITY = "iPhone Developer" MY_DEVELOPMENT_TEAM.name = DEVELOPMENT_TEAM MY_DEVELOPMENT_TEAM.value = CDXXXXXX2B QMAKE_MAC_XCODE_SETTINGS += MY_DEVELOPMENT_TEAM ..... } see see https://bugreports.qt.io/browse/QTCREATORBUG-16968 (take a look at all comments) the good news: Qt 5.9 and QtCreator 4.3 will make your life easier: http://blog.qt.io/blog/2017/05/24/qt-creator-4-3-0-released/

    @Schluchti said in QStandardPaths::standardLocations on iOs returns path that doesn't exist - intended behavior?: @ekkescorner If I got you right, then you are also creating the directory first on iOs, right? YEP

    ?
    Thanks for your reply. For example I have used wiringPi Library for Raspberry pi developed code using QT creator IDE. Now I want to cross compile that into UP Board. Is it possible to use wiring Pi ? Because if I want to use mraa I want to modify everything. So for cross compilation how to proceed ?
