Recording does not check whether the target path exists already about obs-studio HOT 5 OPEN

There are some things we could try to prevent this at least, e.g. the first instance to decide on a filename could touch the file so it exists as a 0-byte placeholder until the output and encoder are ready to start writing actual data.

We can probably leave this open for now.

I have retested with OBS 30.1.2, the issue remains, here are the new logs:

OBS does check if a file already exists unless the "Overwrite if file eixsts" option is enabled in advanced settings. It's possible that you're running into a race condition where the file simply does not exist yet by the time the check runs. Just use different output folders or filename formats.

I do not have the "Overwrite if file exists" option checked and I am clicking the 2 buttons manually with around 300ms in between (according to the logs).

Just for testing I have changed the format to always collide and I can confirm that given enough time between the 2 button presses, OBS will create a second file with (2) in the filename, so this looks to be a race condition.

Next time I will write to different folders but this was just bad luck where I have lost one of my recordings due to this, but I believe in reporting issues even if I already know the solution (for example, wait 1 second between starting each recording session).
