![]() ![]() This module provides a Python API which is very similar to that of OpenCV VideoCapture. Sudo docker run -it -ipc=host -env="DISPLAY" -v $(pwd):/home/video_cap -v /tmp/.X11-unix:/tmp/.X11-unix:rw mv-extractor /bin/bash You can install the motion vector extractor via pip Hence, I gladly welcome any community contributions. However, I do not have the time and resources to do this alone. The mv-extractor seems to be quite popular and I want to improve it. Changed Docker image to manylinux_2_24_x86_64 to prepare for building wheels.Updated demo script with command line arguments for extraction and storing of motion vectors.Provided a script to wrap Docker run command.Updated for compatibility with Python >3.8.The image below shows a video frame with extracted motion vectors overlaid,Ī usage example can be found in extract_mvs.py. These additional features enable further projects, such as fast visual object tracking or synchronization of multiple RTSP streams. (for RTSP streams): UTC wall time of the moment the sender sent out a frame (as opposed to an easily retrievable timestamp for the frame reception).It returns the following values for each frame: This class is a replacement for OpenCV's VideoCapture and can be used to read and decode video frames from a H.264 or MPEG-4 Part 2 encoded video stream/file. This tool extracts frames, motion vectors, frame types and timestamps from H.264 and MPEG-4 Part 2 encoded videos. ![]()
