bool avtranscoder::VideoEncoder::encodeFrame ( const Frame &  sourceFrame, CodedData &  codedFrame  )

virtual

Encode a new frame, and get coded frame.

Parameters

sourceFrame	frame that needs to be encoded
codedFrame	output encoded coded data (first frames can be delayed)

Returns

status of encoding

Exceptions

runtime_error

if the encoded process failed.
