Updating DLC-Live! GUI to pyside6 and multicamera support by arturoptophys · Pull Request #35 · DeepLabCut/DeepLabCut-live-GUI

arturoptophys · 2026-01-13T12:05:03Z

This PR supercedes the #34

Compared to the previos PR this:

changed the pqt bindings to pyside6
added simultaneuos multicamera support (with multiple backends)
added h265 hardware encoding as well as mac-specific hardware encoding options

…modern-python-and-pyqt6 Add Basler and GenTL camera backends for modular capture

…era-functionality

…camera-functionality Rework layout and camera handling controls

…' into artur/test_update

…r integration - Implemented `get_device_count` method in `GenTLCameraBackend` to retrieve the number of GenTL devices detected. - Added `max_devices` configuration option in `CameraSettings` to limit device probing. - Introduced `BoundingBoxSettings` for bounding box visualization, integrated into the main GUI. - Enhanced `DLCLiveProcessor` to accept a processor instance during configuration. - Updated GUI to support processor selection and auto-recording based on processor commands. - Refactored camera properties handling and removed deprecated advanced properties editor. - Improved error handling and logging for processor connections and recording states.

@arturoptophys, great PR! I think this is going to be super helpful.

I think we should aim to merge as soon as DeepLabCut-live 1.2 release is official. This PR is getting quite big already.

Let me know if you want me to look at specific components that you are unsure of / need help with.

Ofc it would be great to add some testing as well..

I think setup.py should be removed. All information is in pyproject.toml now, and having this duplicated list of dependencies here is only confusing (or potentially conflicting). Setuptools works perfectly fine without setup.py now, since you made the pyproject.toml PEP 517 / 518 / 621–compliant.

You could keep only the following code if you want:

Suggested change

from setuptools import setup

# Only kept for compatibility with external legacy tools.

# All information is now in pyproject.toml.

setup()

Maybe also add basler here:

Maybe add an additional block on how to install from source:

Editable Installation from Source (for contributors or advanced users)

Clone the repository

git clone https://github.com/DeepLabCut/DeepLabCut-live-GUI.git cd DeepLabCut-live-GUI

Install editable package using pip or the uv package manager

# Using pip pip install -e . # Or using uv uv sync

+2. **Select Camera Backend**: Choose from the dropdown (opencv, gentl, aravis, basler)

-#### Processor (optional)
+3. **Configure Camera**: Set FPS, exposure, gain, and other parameters


This section is not updated for the multi-camera setup yet, is it?

+The GUI supports PyTorch DLCLive models:

-If you would not like to save the data from the session, please click `Delete Video`, and all data will be discarded. After you click `Save Video` or `Delete Video`, the `Off` button will be selected, indicating you can now set up a new session.
+1. **PyTorch**: PyTorch-based models (requires PyTorch installation)


Ideally the Pytorch dependency is automatically handled by DeepLabCut-live to avoid issues.

+dependencies = [
+    "deeplabcut-live", # might be missing timm and scipy


Let's specify this minimal version (old version is incompatible). And let's have the PyTorch dependency handled by deeplabcut-live (installs scipy, timm and torch automatically).

Suggested change

"deeplabcut-live", # might be missing timm and scipy

"deeplabcut-live[pytorch] >= 1.1.0"

NOTE: the required deeplabcut-live version is not officially released yet

on my windows machine the current dlclive3 branch installed with [pytorch] flag does not install cuda-compiled version of pytorch i had to manually install pip3 install torch torchvision --index-url https://download.pytorch.org/whl/cu130

I encountered this race condition: when stopping, _stop_worker() sets self._queue = None (line 236) while the worker thread is in the finally block. (I think..?)

Suggested change

self._queue.task_done()

if self._queue is not None:

self._queue.task_done()
