The app, when using with gphoto2 plugin, will cause a lot of memory leaks (see the last line of terminal output), as shown in the screen recording below:

OBS Studio is software designed for capturing, compositing, encoding,
recording, and streaming video content, efficiently. _This is a
community-supported modified build of OBS Studio; please file issues on the
Snapcrafters GitHub:_ https://github.com/snapcrafters/obs-studio/issues
**Batteries included**
The snap of OBS studio comes pre-loaded with some extra features:
* Supports **nvenc (NVIDIA) and VA-API (AMD & Intel) accelerated video
encoding**.
* **Advanced Scene Switcher** plugin; an automated scene switcher
* **Browser** plugin; CEF-based OBS Studio browser plugin
* **Directory Watch Media** plugin; filter you can add to a media source
to load the oldest or newest file in a directory.
* **Dynamic Delay** plugin; filter for dynamic delaying a video source.
* **Freeze Filter** plugin; freeze a source using a filter.
* **gPhoto** plugin; connect DSLR cameras with obs-studio via gPhoto.
* **GStreamer** plugins; feed GStreamer launch pipelines into OBS Studio
and use GStreamer encoder elements.
* **Move Transition** plugin; move sources to a new position during a
scene transition.
* **NDI** plugin; Network A/V via NewTek's NDI.
* **NvFBC** plugin; screen capture via NVIDIA FBC API. Requires NvFBC
patches for Nvidia drivers for consumer-grade GPUs.
* **RGB Levels** plugin; simple filter to adjust RGB levels.
* **Source Switcher** plugin; to switch between a list of sources.
* **Spectralizer** plugin; audio visualization using fftw.
* **StreamFX** plugin; collection modern effects filters and transitions.
* **Text Pango** plugin; Provides a text source rendered using Pango with
multi-language support, emoji support, vertical rendering and RTL
support.
* **Transition Matrix** plugin; customize Any -> One or One -> One scene
transitions.
* **VNC Source** plugin; VNC viewer that works as a source.
* **Websockets** plugin; remote-control OBS Studio through WebSockets.
**Connecting Interfaces**
For the best experience, you'll want to connect the following interfaces.
sudo snap connect obs-studio:alsa
sudo snap connect obs-studio:audio-record
sudo snap connect obs-studio:avahi-control
sudo snap connect obs-studio:camera
sudo snap connect obs-studio:jack1
sudo snap connect obs-studio:kernel-module-observe
**NDI**
If you want to use the NDI plugin you'll need to connect the Avahi Control
interface.
snap connect obs-studio:avahi-control
**Virtual Camera**
Starting with OBS 26.1.0, Virtual Camera support is integrated. Here's how
to install and configure `v4l2loopback`:
sudo snap connect obs-studio:kernel-module-observe
sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
echo "options v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
Camera' exclusive_caps=1" | sudo tee
/etc/modprobe.d/v4l2loopback.conf
echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
sudo modprobe -r v4l2loopback
sudo modprobe v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
Camera' exclusive_caps=1
**NOTE!** Using `video_nr` greater than 64 will not work.
**Removable Storage**
To access content on external storage, connect to the removable-media plug:
snap connect obs-studio:removable-media
**gPhoto**
The gPhoto plugin allows some DSLR cameras to be connected via USB. You'll
need to connect the Raw USB interface.
snap connect obs-studio:raw-usb
**3rd Party plugins**
To install pre-compiled plugins, download and extract the plugin to
`~/snap/obs-studio/current/.config/obs-studio/plugins/`.
This is how the Input Overlay plugin looks when correctly installed:
/home/username/snap/obs-studio/current/.config/obs-studio/plugins/
└── input-overlay
├── bin
│ └── 64bit
│ └── input-overlay.so
└── data
└── locale
├── de-DE.ini
├── en-US.ini
└── ru-RU.ini
If you want to use the Input Overlay plugin, you'll also need to connect
the joystick interface:
snap connect obs-studio:joystick
commands:
- obs-studio.eglinfo
- obs-studio.ffmpeg
- obs-studio.ffplay
- obs-studio.ffprobe
- obs-studio.glxinfo
- obs-studio
- obs-studio.srt-ffplay
- obs-studio.srt-file-transmit
- obs-studio.srt-live-transmit
- obs-studio.srt-tunnel
- obs-studio.vainfo
- obs-studio.vdpauinfo
- obs-studio.vulkaninfo

info: Number of memory leaks: 15
I tried launching my local gphoto2 with:
gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 2 -f v4l2 /dev/video13
There's no memory leak at all.
Note: my dummy video device is at /dev/video13 which I checked it by v4l2-ctl --list-devices. I can use my camera through gphoto2 directly. But I would prefer using it through OBS which would provide a lot more options.
The memory leaks message is output by OBS. I doubt it is specific to the gphoto plugin, tho I cannot be 100% certain. It is also unlikely to be specific to the Snap Packaged release of OBS (https://github.com/obsproject/obs-studio/blob/f5be6f5fdd2fe34b18518ecd38030f0768845688/UI/obs-app.cpp#L3068)
Is it possible for you to check a non-snapped version of OBS with the gphoto plugin to see if it occurs only with the Snap Package? If it is reproducible with a copy of OBS that isn't from the Snap Package then you have two options below for further steps:
- If you can confirm that it is definitely the gphoto2 plugin then please report it at the gphoto plugin's issue tracker: https://github.com/Atterratio/obs-gphoto/issues/new
- If it is an issue with OBS without using the gphoto2 plugin then please report it at the OBS issue tracker: https://github.com/obsproject/obs-studio/issues
If it is an issue that is specific to the Snap Package then we can look into further diagnostics to attempt to narrow down why the Snap is different.
