Detailed Description

MPEG 1/2 video decoder.

Used by BMP/AVI.

Member Function Documentation

decodeFrame()

const Graphics::Surface* Image::MPEGDecoder::decodeFrame ( Common::SeekableReadStream &  stream )

overridevirtual

Decode the frame for the given data and return a pointer to a surface containing the decoded frame.

Returns

a pointer to the decoded frame

Implements Image::Codec.

getPixelFormat()

Graphics::PixelFormat Image::MPEGDecoder::getPixelFormat ( ) const

inlineoverridevirtual

Get the format that the surface returned from decodeImage() will be in.

Implements Image::Codec.

setOutputPixelFormat()

bool Image::MPEGDecoder::setOutputPixelFormat ( const Graphics::PixelFormat &  format )

inlineoverridevirtual

Select the preferred format to use, for codecs where this is faster than converting the image afterwards. Returns true if supported, and false otherwise.

Reimplemented from Image::Codec.
