    initial commit
    
    - re-starting version control fresh
    - old repo had video files committed + node modules at one point that made it much larger than needed

+# webcam_manager
+
+en avant les commits!
+
+
+## Installation 
+
+We are looking to package this as a bundled application, in the meantime to install and run the Python code: 
+
+### Python dependencies
+
+See `pyproject.toml` for requirements to install.
+
+### Linux
+
+On linux [v4l2loopback](https://github.com/umlaeute/v4l2loopback) is required to create a virtual webcam that can be used in call software.
+
+```
+sudo apt install v4l2loopback-dkms
+```
+
+The program starts the service automatically (this is why it asks for the sudo password at startup) to start manually: 
+
+```
+sudo modprobe v4l2loopback devices=1
+```
+
+### Windows 
+
+On Windows OBS is required 
+
+add details here 
+
+### MacOS
+
+Coming soon...
+
+## Usage
+
+### Connect to call software 
+
+### Recording and looping
+

+
+# TODO
+
+- [ ] V4L2 warnings on Linux 
+  - 9 warnings so I guess one for each camera that is not found (we test for 10 devices in `camera_indexes()`)
+
+- [ ] Stealth button names/colors
+  - icons only? see [this](https://pysimplegui.readthedocs.io/en/latest/cookbook/#use-with-buttons)
+
+- [ ] Start modprobe service automatically from Python? 
+  - probably can call a `subprocess` or something. Probably check first if the `v4l2loopback` package exist, and if not display the command to execute? 
+
+- [ ] Package Font?
+  - Title using [Steps Mono](https://www.velvetyne.fr/fonts/steps-mono/download/) libre font from Velvetyne.
+  - Can we embed it/package it? 
+  - let's see how it goes when we use `pyinstaller`. As far as I understand `pysimplegui` uses `tkinter` to manage fonts, so checking how tkinter does it might give us a clue.
+    - https://stackoverflow.com/questions/63585632/how-to-add-a-truetype-font-file-to-a-pyinstaller-executable-for-use-with-pygame
+
+- [ ] How do we package the rest anyway?
+  - Cookiecutter: https://cookiecutter.readthedocs.io/en/1.7.2/index.html
+
+  - package FFMPEG builds and include in pyinstaller
+https://stackoverflow.com/a/57081121
+https://stackoverflow.com/a/60822647
+
+## DONE
+
+- [x] Keyboard shortcuts
+  - ~~to easily start/stop recording: space bar~~
+  - ~~start/stop loop: enter?~~
+  - Done and tested on Windows!!
+
+- [x] Added device selector for the camera, to be tested elsewhere
+
+- [x] Added a flush function 
+  - Empties the video recorded in static at the start of the application
+  - Added a `Flush` button next the `Exit`
+
+- [x] Pick normcore theme
+
+- [x] create `static/` if it doesn't exist.
+  
+- [x] Output of virtualcam (e.g. previewing in Jitsi) has weird smurf colors.
+  - ~~preview in window is fine~~ 
+  - ~~recorded output file was fine~~
+  - preview in window fine, recorded out fine, preview in Zoom fine.
+  
+- [x] Are we downsizing the video resolution? why not use best res available? (line 57 see # XXX)
+  - we was, now we're webcam native size
+  
+- [x] Click on LOOP after launch before recording crashes
+  - ~~`variable referenced before assignment`~~
+  - fixed. If you click LOOP first and there's no static videos, the button gets disabled. Also added colours and disabled buttons
+
+- [x] Stop saving video files locally?
+  - or at least add to `.gitignore`?
