static

◆ create() [2/2]

static VideoEncoder* QtAV::VideoEncoder::create ( const char * name = "FFmpeg" )

Parameters

name	can be "FFmpeg". FFmpeg encoder will be created for empty name

Returns: 0 if not registered

◆ encode()

virtual bool QtAV::VideoEncoder::encode ( const VideoFrame & frame = VideoFrame() )

pure virtual

encode encode a video frame to a Packet

Parameters

frame pass an invalid frame to get delayed frames

Returns

signal

◆ Register()

template<class C >

inlinestatic

◆ setFrameRate()

void QtAV::VideoEncoder::setFrameRate ( qreal value )

TODO: check avctx->supported_framerates. use frame_rate_used.

setFrameRate If frame rate is not set, frameRate() returns -1, but internally the default frame rate 25 will be used

Parameters

value

◆ setHeight()

void QtAV::VideoEncoder::setHeight ( int value )

◆ setPixelFormat()

void QtAV::VideoEncoder::setPixelFormat ( const VideoFormat::PixelFormat format )

setPixelFormat If not set or set to an invalid format, a supported format will be used and pixelFormat() will be that format after open()

Parameters

format

◆ setWidth()

void QtAV::VideoEncoder::setWidth ( int value )

output parameters

setWidth set the encoded video width. The same as input frame size if value <= 0

◆ supportedCodecs()

static QStringList QtAV::VideoEncoder::supportedCodecs ( )

static

◆ width()

int QtAV::VideoEncoder::width ( ) const

◆ widthChanged
