> arethian: <amolith/tg> jgart, yep I used the script. It takes care of everything
> 03/05/2022 | 08:02:02 AM arethian: <amolith/tg> Note, that you will need an additional sever for TURN but it can be pretty lightweight

```
What I used:
```
ffmpeg -i Pjotr-NoSQL-2022-slides.webm -i Pjotr-NoSQL-2022-webcam.webm -vf "movie=Pjotr-NoSQL-2022-webcam.webm, scale=210:-1 [inner]; [in][inner] overlay=10:10 [out]" tmp.mkv
```
use -ss for start time
```
ffmpeg -ss 00:06:22 -i tmp.webm tmp.mkv
```
For Amelie:
```
ffmpeg -i deskshare1.webm -vf "movie=webcams1.webm, scale=210:-1 [inner]; [in][inner] overlay=10:10 [out]" tmp.mp4
```
```
ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=s=x:p=0 tmp.webm
```
## Extra
Convert files using ffmpeg adding in the webcam (right justified):
```
ffmpeg -i deskshare.webm -vf "movie=webcams.webm, scale=330:-1 [inner]; [in][inner] overlay=940:-1 [out]" tmp.mp4
```
Reversed audio try
```
ffmpeg -i deskshare.webm -i webcams.webm -vf "movie=webcams.webm, scale=330:-1 [inner]; [in][inner] overlay=940:-1 [out]" tmp.webm
```
