Yes...Same issue here. I'm using the Flatpak version of OBS.Something seems to be broken in the latest OBS release. Yesterday I have been pulling my hair all day trying to figure out why I got the "Stopping recording ..." message when using Source Record on a clean install of OBS 30.1.
When I did a new install of OBS 30.0.02 with Source Record everything seems to be working again just fine.
Anyone else having similar experiences?
After upgrading to OBS 30.1, "Source Record" plugin still works, except it won't stop recording when I clicked "Stop Recording..." on OBS main control dock, thus showing the "Stopping recording..." message. Until I exit OBS completely, at which point OBS would prompt me with a message indicating some recording is still ongoing and asked if I really wanted to "Quit". Only after I exited OBS would the "Source Record" plugin stopped recording. I confirmed that after checking the corresponding recorded videos' time-stamp and length.
I can also confirm that by downgrading OBS to 30.0.2 would restore the stop recording functionality for "Source Record" plugin.
I like the added feature (not to mention fixes) in OBS 30.1 such as VAAPI-AV1 support, but I also need to retain the ability to record a source separately. But if I have to choose, I would go back to OBS 30.0.2.
Lastly, many thanks to Exeldro for this amazing plugin (and many others). I've been a fan for several years now and can't say enough how his plugins have streamlined my streaming and recording sessions! Thanks again.
