• classLabel for the whole video can be registered with on right. new classButtons can be added with the New Class lineEdit provided.
• click next Video button to save the registered frameTags, frameLabels and classLabel to a json file with the same video name in labelFolderPath selected at the start with select Folder Dialog

Labels Format

{"frameLabels":[["Up", ["P", "R"]],
               [["Left", ["P", "R"]]
                .
                .
                .

                ],
 "classLabel" :"SomeClass",
 "config"     :{}
}

where:

• ["P", "R"] is the sorted list of Tags for the 1st and 2nd frame
• "Up" is the frameLabel for 1st frame registered by pressing Up_Arrow
• "someClass" is the classLabel for whole video, registered by pressing push buttons on the right, and new classes can be added on the fly
• "config" is currently of no use and can be used to save more fine information of the frames in future

Screens

Bugs

• Crashes with segmentation fault in windows on selecting the paths and doesn't display even a single frame
• Randomly crashes in Linux with same segmentation fault but resumes at the same video without any loss of data for the previously labeled videos as they are already exported to json, and the <labelFolderPath>/config/config.json tracks the index, so restarting gets the last shown video, not having to go through already labeled videos.
