static VideoEncoder* QtAV::VideoEncoder::create ( VideoEncoderId id )

static

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

static

create create an encoder from registered names

Parameters

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

Returns: 0 if not registered

inlinestatic

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

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

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

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

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

output parameters

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