A pyGTK and vlc based application to hand-annotate audio and video files for classification tasks
Project description
pyMediaAnnotator
A GTK+ and vlc based application for annotating video and audio files for classification tasks
Features:
- Add text annotations time-locked to content in media file
- Annotate time accurate to the millisecond
- Jump to annotation start time to verify correctness
- Standard media playback features (play/pause, stop, seek)
- Change annotation task mid-video
- Edit annotation label for particular time segment
- Delete annotation entry
- Undo annotation segment (in the order of most recent)
- Sort annotations by starttime by clicking on column header so that you can go back and re-annotate a particular segment of media
Planned features and bugfixes for future releases:
- The YAML format was chosen because it is convenient and human-readable. However, in the future, the user should be able to choose output format (
json
,pickle
,txt
, Numpy array, etc.) - Fix seek bar synchronization with playback
- Multiple button support for rapid multiclass annotation
- Save and resume existing annotation
Installation:
From pyPI using pip
:
python3 -m pip install --upgrade [--user] pyMediaAnnotator
The --user
flag installs it locally
without needing root
(optional).
If you are able to ensure the availability of GTK bindings from some other source, you could skip installing pyGTK:
python3 -m pip install --upgrade [--user] --no-deps pyMediaAnnotator
From source
- Clone the repository
git clone https://gitlab.com/aalok-sathe/pyMediaAnnotator.git
- Make sure to have the necessary prerequisites:
pyGTK/pyGTK/pyGObject
: Python GTK bindingsvlc
,python-vlc
: the VLC media player and Python bindings forlibvlc
- Create Python package and install:
make build
python3 setup.py install
Usage:
- Start application with the executable:
./pyMediaAnnotator
- Screenshot (v0.1.2): example usage to annotate the laugh track in an episode of Friends ![example usage](scrsht-friends.png?raw=true Screenshot")
Compatibility:
- GNU/Linux, *NIX [recommended]:
- Expected to run with proper prerequisites
- Tested on Ubuntu 16.04
- Any other system:
- Not tested, however, should theoretically work long as you are able to provide pyGTK and libvlc support
