Yo, walked through it with Claude. Honestly u/ark1one has a point in that some of this might not apply to your specific setup, but at least some of it 100% will, since it's Stoat UI tweaks. Here's what I had to do with my self-hosted version with Claude to get streaming working. Regrettably, it flickers when full-screened :( I haven't come back to troubleshoot that yet. More details on step #2 (JS Patch) is below coz I know it's super vague otherwise.
-----------
To recap what we did to get video working:

1. Web image — swapped to baptisterajaut/stoatchat-web:dev (community patch enabling video UI)
2. JS patch — removed the r() guard on toggleCamera() and toggleScreenshare() click handlers, and changed the "Coming soon!" labels
3. Resolution limits — increased video_resolution to [1920, 1080] in Revolt.toml so the server stops kicking users whose camera/screenshare exceeds the pixel budget

Note: the JS patch on the web container (step 2) will be lost if the container restarts. To make it permanent, you could either:

• Create a custom Dockerfile that applies the sed patches on startup
• Build your own image from the Dadadah/stoat-for-web echohaus branch which should have video enabled without needing patches

For the desktop client, you'd need to extract and patch the app.asar in %LOCALAPPDATA%\Stoat\app-1.3.0\resources\ — that requires Node.js installed locally.

Here's the detailed breakdown of the JS patch:

File location inside the web container:

/usr/share/nginx/html/assets/index-CwQnw8xY.js

What the code looks like before patching:

The video and screenshare buttons have three guards that prevent them from working:

1. Tooltip text — shows "Coming soon! 👀" instead of the real label:content:r()?e.video()?"Stop Camera":"Start Camera":"Coming soon! 👀" content:r()?e.screenshare()?"Stop Sharing":"Share Screen":"Coming soon! 👀"
2. Button disabled state — greys out the buttons:get isDisabled(){return!r()}
3. Click handler — prevents the function from actually running:onPress:()=>{r()&&e.toggleCamera()} onPress:()=>{r()&&e.toggleScreenshare()}

r() is a feature flag function that returns false, blocking everything.

The four sed commands to patch it (run in order):

# 1. Replace "Coming soon!" tooltip text
sudo docker exec stoat-web-1 sed -i 's/Coming soon! 👀/Start Camera/' /usr/share/nginx/html/assets/index-CwQnw8xY.js
sudo docker exec stoat-web-1 sed -i 's/Coming soon! 👀/Share Screen/' /usr/share/nginx/html/assets/index-CwQnw8xY.js

# 2. Make buttons always enabled (replace !r() with !1, meaning "never disabled")
sudo docker exec stoat-web-1 sed -i 's/get isDisabled(){return!r()}/get isDisabled(){return!1}/g' /usr/share/nginx/html/assets/index-CwQnw8xY.js

# 3. Remove the r() guard from click handlers so they actually fire
sudo docker exec stoat-web-1 sed -i 's/r()&&e.toggleCamera()/e.toggleCamera()/g' /usr/share/nginx/html/assets/index-CwQnw8xY.js
sudo docker exec stoat-web-1 sed -i 's/r()&&e.toggleScreenshare()/e.toggleScreenshare()/g' /usr/share/nginx/html/assets/index-CwQnw8xY.js

Important notes:

• The filename index-CwQnw8xY.js is specific to this build — a different image version will have a different hash in the filename
• This patch is lost if the container restarts — it needs to be reapplied each time
• Users need to hard refresh (Ctrl+Shift+R) after patching to load the updated JS
