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 <QAudioOutput>
#if _QT6_
#include <QList>
#include <QVideoFrameFormat>
#include <QAudioDevice>
#include <QVideoSink>
#include <QAudioSink>
#include <QCameraDevice>
#include <QMediaDevices>
#include <QMediaMetaData>
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 QAudioDevice QtAudioDevice;
typedef QAudioDevice::Mode QtAudioDeviceMode;
#define QtAudioDeviceMode_Input QAudioDevice::Input
#define QtAudioDeviceMode_Output QAudioDevice::Output
QList<QAudioDevice>
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 {
void play(const QString& path);
};
// ------------------------
typedef QCameraDevice QtCameraDevice;
// ------------------------
#define getDeviceName() description()
#else // _QT6_
#include <QVideoSurfaceFormat>
#include <QAudioDeviceInfo>
#include <QAbstractVideoSurface>
#include <QCameraInfo>
#include <QSound>
typedef QVideoSurfaceFormat QtVideoFrameFormat;
typedef QVideoFrame::PixelFormat QtVideoFramePixFormat;
typedef QAbstractVideoSurface QtAbstractVideoSurface;
#define getVideoSurface() videoSurface()
#define getAvailableVideoDevices() QCameraInfo::availableCameras()
#define setMediaSoure setMedia
#define QMediaPlayer_PlaybackState QMediaPlayer::State
#define getPlaybackState() state()
// ------------------------
typedef QAudioDeviceInfo QtAudioDevice;
typedef QAudio::Mode QtAudioDeviceMode;
#define QtAudioDeviceMode_Input QAudio::AudioInput
#define QtAudioDeviceMode_Output QAudio::AudioOutput
#define getAvailableAudioDevices(_type)
QAudioDeviceInfo::availableDevices(_type)
#define getDefaultAudioDevice()
QAudioDeviceInfo::defaultOutputDevice()
#define QAudioFormat_SampleType QAudioFormat::SampleType
#define getSampleType() sampleType()
#define getSupportedSampleTypes() supportedSampleTypes()
#define bitsPerSample() sampleSize()
typedef QAudioOutput QtAudioSink;
// ------------------------
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:
