Exemple #1

Fichier : H264Encoder.cpp Projet : dulton/avkit-1

XIRef<XMemory> H264Encoder::EncodeYUV420P( XIRef<XMemory> pic,
                                           FrameType type )
{
    XIRef<XMemory> frame = new XMemory( DEFAULT_ENCODE_BUFFER_SIZE + DEFAULT_PADDING );

    uint8_t* p = &frame->Extend( DEFAULT_ENCODE_BUFFER_SIZE );

    size_t outputSize = EncodeYUV420P( pic->Map(),
                                       frame->Map(),
                                       frame->GetDataSize(),
                                       type );
    frame->ResizeData( outputSize );
    return frame;
