class Decoder(__builtin__.object) |

Decoder( codecParams ) -> Decoder
Creates new video decoder object based on codecParams.
codecParams - dictionary with the following items parameters:
'id', 'fourcc', 'type', 'bitrate', 'width', 'height',
'format', 'data', 'size', 'rate',
'rate_base', 'frame_rate', 'frame_rate_base', 'gop_size'
'max_b_frames', 'deinterlace'
The list of available codecs may be accessed through vcodec.codecs
All possible formats can be obtained through vcodec.formats
Methods of Decoder are:
convert( format {, size } ) -> frame
Convert existing video frame into another format with all needed color conversions and scaling.
getParams() -> params
Parameters that represents the current state of codec

Encoder( codecParams ) -> Encoder
Creates new video encoder object based codecParams.
codecParams - dictionary with the following items parameters:
'id', 'fourcc', 'type', 'bitrate', 'width', 'height',
'format', 'data', 'size', 'rate',
'rate_base', 'frame_rate', 'frame_rate_base', 'gop_size'

The list of available codecs may be accessed through vcodec.codecs
All possible formats to the convert video frame to are available trough vcodec.formats
Methods of Encoder are:
encode( frame, [ scale ]-> encoded string
Encode frame

class VFrame(__builtin__.object) |
| |
VFrame( format, size, data ) -> VFrame
Create a new VFrame with the parameters passed.
The 'format' should be one from vcodec.formats and the 'size' should represent the actual size of the frame( w, h )
If you create RGB picture, make sure that 'data' contains 3 strings as below: ( RGB, None, None )
