* Fix: Return the result of rendering from dummyvecenv
* Add: Add a video recorder wrapper for vecenv
* Change: Use VecVideoRecorder with --video_monitor flag
* Change: Overwrite the metadata only when it isn't defined
* Add: Define __del__ to make the file correctly closed in exit
* Fix: Bump epidode_id in reset()
* Fix: Use hasattr to check the existence of .metadata
* Fix: Make directory when it doesn't exist
* Change: Kepp recording for `video_length` steps, then close
Because reset() is not what it is in normal gym.Env
* Add: Enable to specify video_length from command line argument
* Delete: Delete default value, None, of video_callable
* Change: Use self.recorded_frames and self.recording to manage intervals
* Add: Log the status of video recording
* Fix: Fix saving path
* Change: Place metadata in the base VecEnv
* Delete: Delete unused imports
* Fix: epidode_id => step_id
* Fix: Refine the flag name
* Change: Unify the flag name folloing to previous change
* [WIP] Add: Add a test of VecVideoRecorder
* Fix: Use PongNoFrameskip-v0 because SimpleEnv doesn't have render()
* Change; Use TemporaryDirectory
* Fix: minimal successful test
* Add: Test against parallel environments
* Add: Test against different type of VecEnvs
* Change: Test against different length and interval of video capture
* Delete: Reduce the number of tests
* Change: Test if the output video is not empty
* Add: Add some comments
* Fix: Fix the flag name
* Add: Add docstrings
* Fix: Install ffmpeg in testing container for VecVideoRecorder's test
* Fix: Delete unused things
* Fix: Replace `video_callable` with `record_video_trigger`
* Fix: Improve the explanation of `record_video_trigger` argument
* Fix: Close owning vecenv in VecVideoRecorder.close to resolve memory
