Method and arrangement for video transcoding using mode or motion or in-loop filter information

A system for transcoding a video bitstream, comprising:

• a transmitter;
• a memory;
• and
• a processor, the processor coupled to the memory and configured to:
• receive a video bitstream with a predetermined input video format;
• receive side information related to an original video format of the received video bitstream, said side information comprising at least one of:
• a mode or a motion;
• generate transcoding guiding information for encoding the received video bitstream, the transcoding guiding information based on the received side information and comprising at least one of:
• a suggested mode or a suggested motion;
• and
• employ the transmitter to transmit the transcoding guiding information to a transcoding node.

A computer program product comprising a non-transitory computer readable medium storing a computer program comprising instructions which when executed by processing circuitry causes the processing circuitry to perform the method of:

• receiving a video bitstream with a predetermined input video format;
• receiving side information related to an original video format of the received video bitstream, said side information comprising at least one of:
• a mode or a motion;
• generating transcoding guiding information for encoding the received video bitstream, the transcoding guiding information based on the received side information and comprising at least one of:
• a suggested mode or a suggested motion;
• and
• sending the transcoding guiding information to a transcoding node.
