Bambu Studio Flathub - Go Live

[immortel32]

Bambu Studio Version

1.9.2

Where is the application from?

Built from source by yourself or others

OS version

Linux mint 21.3

Additional system information

No response

Printer

Bambu Lab X1c

How to reproduce

Install Bambu Studio with Flathub
Enable the Go Live option
Configure OBS Studio to read the file /home/myuser/.var/app/com.bambulab.BambuStudio/config/BambuStudio/cameratools/ffmpeg.sdp

Actual results

I got a black screen (nothing happens)

Expected results

I'm expecting to see the live camera on my printer.
If I do it with AppImage and use the file in /home/myuser/.config/BambuStudio/cameratools/ffmpeg.sdp, it is working fine.

The reason of using Flathub intead of AppImage is because it manages Bambu Studio upgrades. The last I check with AppImage it did not warn me when a new version was available.

Can be done with any STL

This is what I get with the application from flathub

ps -ef | grep ffm

This is what I get with the appimage
ps -ef | grep ffm myuser 5773 1 1 21:20 pts/0 00:00:02 /home/myuser/.config/BambuStudio/cameratools/ffmpeg -fflags nobuffer -flags low_delay -analyzeduration 10 -probesize 3200 -f h264 -i pipe: -vcodec copy -f rtp rtp://127.0.0.1:1234

There is a lot of "sensitive data" in the logs. What do you need? (There is nothing in the logs with ffmpeg).

I need the log lines with "MediaPlayCtrl".

I am also experiencing this issue. I get about five seconds of video, then it freezes, and I also have a ffmpeg [defunct] process that hangs around (i.e., is not being reaped by the parent process) until I quit BambuStudio. If I stop-and-start the video from within BambuStudio, I get another five seconds (and so on).

The following are running:

FYI, I would not need this fixed if #1536 was addressed.
