Extracting Motion Vector #26

Dear all, Thanks for your interesting implementation. There is a question, Is the motion vector extracted after the decoding process? Best regards

Yes it is. motion vector are extracted after complete decoding process. It is necessary since the encoder only contains the Motion difference (MVD) and not the complete vector source and destiny. Also the motion difference coding is dependent of CABAC or CAVLC
