In some embodiments, a method receives a current encoding stream of a video. A first measurement for a reference encoding stream is selected to measure a quality of the reference encoding stream. The method compares a second measurement of the current encoding stream to the first measurement of the reference encoding stream and outputs whether the current encoding stream is validated based on the comparing.

According to an aspect of the invention there may be provided a method of decoding a bitstream, the method comprising: receiving a Supplemental Enhancement Information (SEI) message; parsing the SEI message to obtain an encoded bitstream, said encoded bitstream containing encoded information which is associated with information of an original signal; and, decoding said encoded bitstream to obtain decoded information which is used to reconstruct the original signal. A method of decoding is also provided as well as apparatuses and a computer readable medium.

Provided is a method for encoding video data. The method includes: acquiring video data; configuring an encoding parameter of an encoder; determining a first time interval between two adjacent video frames in a group of pictures based on the encoding parameter; and adjusting a number of video frames in the group of pictures based on the first time interval by encoding the video data based on the encoding parameter. A device and a storage medium are also provided.

The present invention generally relates to a technology of effectively performing video analysis of a compressed video (e.g., H.264 AVC, H.265 HEVC) in a video analysis system. More specifically, the present invention relates to a video analysis technology of a compressed video (e.g., CCTV video) in which branching in the video analysis process is performed with referring to motion vectors which have been obtained by parsing the compressed video, so that computing resource for the video analysis of the compressed video may be lowered. The present invention may provide an advantage of lowering the computer resource which is required for analyzing a compressed video (e.g., CCTV video).
