[Interest] "Activate your 10-day Qt 6 evaluation now"

2021-08-30 Thread Nuno Santos 
Hi,

What do you do with a 10 days evaluation of Qt 6?

I would say that taking into account the fact that Qt has a new building system 
and qmake is not available anymore, porting an existing project takes much more 
than 10 days.

Any feedback from users that have already tried Qt 6 and are porting their apps 
to it?

Best regards,

Nuno

I'd like to rephrase:
Why not, in which cases, use lgpl license?

That's incorrect. qmake is still available.

Thiago,

Thanks for the clarification.

I was convinced that qmake was not available anymore. My bad! :/

Still, I think 10 days of evaluation is a really short period of time.

I would love to hear feedback from people who have started porting their 
software to Qt 6 and how the effort of such migration.

Regards,

Nuno

I have an app heavily dependent on Multimedia.

it took me about a week and a half total

i created a header "Qt6Bridge.h" that defines a bunch of stuff one way or 
another depending on qt5 or qt6 (have to keep qt5 build alive until Qt6 has all 
the functionality in need).

eg:

#ifndef _H_Qt6Bridge
#define _H_Qt6Bridge

#if _QT_
#include "CFUtils.h"
#include 

#if _QT6_
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

typedef QVideoFrameFormat   QtVideoFrameFormat;
typedef QVideoFrameFormat::PixelFormat  QtVideoFramePixFormat;

typedef QVideoSink  QtAbstractVideoSurface;

#define getVideoSurface()   videoSink()
#define getAvailableVideoDevices()  QMediaDevices::videoInputs()
#define setMediaSoure   setSource
#define QMediaPlayer_PlaybackState  QMediaPlayer::PlaybackState
#define getPlaybackState()  playbackState()

// 
typedef QAudioDeviceQtAudioDevice;

typedef QAudioDevice::Mode  QtAudioDeviceMode;
#define QtAudioDeviceMode_Input QAudioDevice::Input
#define QtAudioDeviceMode_OutputQAudioDevice::Output

QList 
getAvailableAudioDevices(QtAudioDeviceMode ioMode);
#define getDefaultAudioDevice() 
QMediaDevices::defaultAudioOutput()

#define QAudioFormat_SampleType QAudioFormat::SampleFormat
#define getSampleType() sampleFormat()
#define getSupportedSampleTypes()   supportedSampleFormats()
#define bitsPerSample() bytesPerSample() * 8

typedef QAudioSink  QtAudioSink;

namespace QSound {
voidplay(const QString& path);
};

// 
typedef QCameraDevice   QtCameraDevice;

// 
#define getDeviceName() description()

#else   //  _QT6_
#include 
#include 
#include 
#include 
#include 

typedef QVideoSurfaceFormat QtVideoFrameFormat;
typedef QVideoFrame::PixelFormatQtVideoFramePixFormat;

typedef QAbstractVideoSurface   QtAbstractVideoSurface;

#define getVideoSurface()   videoSurface()
#define getAvailableVideoDevices()  QCameraInfo::availableCameras()
#define setMediaSoure   setMedia
#define QMediaPlayer_PlaybackState  QMediaPlayer::State
#define getPlaybackState()  state()

// 
typedef QAudioDeviceInfoQtAudioDevice;

typedef QAudio::ModeQtAudioDeviceMode;
#define QtAudioDeviceMode_Input QAudio::AudioInput
#define QtAudioDeviceMode_OutputQAudio::AudioOutput

#define getAvailableAudioDevices(_type) 
QAudioDeviceInfo::availableDevices(_type)
#define getDefaultAudioDevice() 
QAudioDeviceInfo::defaultOutputDevice()

#define QAudioFormat_SampleType QAudioFormat::SampleType
#define getSampleType() sampleType()

typedef QAudioOutputQtAudioSink;
// 
typedef QCameraInfo QtCameraDevice;

// 
#define getDeviceName() deviceName()
#endif  //  !_QT6_

#endif  //  _QT_
#endif  // _H_Qt6Bridge

I also had to write my own "QVideoFrame_fromImage()" cuz that func no longer 
exists

the rest was working around the fact that you can't multiplex video frames any 
more:
https://bugreports.qt.io/browse/QTBUG-95127
https://bugreports.qt.io/browse/QTBUG-95542

and i'm waiting still on the ability to get predictable audio samples from the 
decoder:
