Does this also happen if you record without audio? Does the audio preview work?
I did not try without audio. The audio preview works. Also i tried on another computer with the same OS version and recording works there. Output of working recording of 15 seconds:

On the computer that is showing the problem, try running simplescreenrecorder --syncdiagram
, and do a test recording. This will show a synchronization diagram, please post a screenshot of it here.
It seems it was a local issue caused by Pulseaudio.
I started the recorder with --syncdiagram and i got the below output:
Video in, no audio in. Tried without audio, it worked (interesting i am sure some audio was showing last time i checked on the preview).
Enabled sound recording again, checked in pavucontrol and indeed simplescreenrecorder was recording not from the specified source, but another one (monitor of the echo-cancel recording thread instead of monitor of internal analog). So it seems Pulseaudio had some manually specified rule for simplescreenrecorder.
If you change the source to the right one, does that solve the problem? Or does it somehow switch back to the wrong source the next time you try to record something?
Yes, if i change the source from pavucontrol to the one i have in ssr, it works with audio too. Afterwards it works too. So it's not a critical issue, but it could help if some kind of error message is provided instead of silently failing...
Hello. I used simplescreenrecorder for some time and was working fine (Debian testing 64 bit). But at least since last week it stopped recording anything. I saw no error messages, it just did not record anything after i pressed record, the file size indicator and duration being at 0. The file is created, but its empty. tried different codecs but none worked. Preview works. See the screenshot, it is after 10 seconds i pressed record. It happened if i compiled manually and with the version from your PPA. What could cause this? Attached screenshot and output from the terminal (started the program, selected the options then pressed record, for about 20 seconds, pressed "save recording" then "back").
