Ok, thanks Marc. I have tried your file (just making it simpler and adding a RPG) and timer does not work for me... I will send the log later when I arrive home. So, just a silly question. Imagine I want a picture every 10 seconds. I would just have to change scheduling period to 10 sec or 10000 msec, right?. Does this work even if I specify FPS: 24?
I noticed that the video profile is chosen based on the FPS value. If I set FPS: 1 I get very large images while with FPS: 24 I get smaller 800x600 images. I guess this will be configured as a property in the future. Best regards, Iyán -----Mensaje original----- De: Marc P.

Here is my config file https://urldefense.proofpoint.com/v2/url?u=https-3A__gist.github.com_phrocker_a209b5163044a5bb3c2e6ac4662ce143&d=DwIFaQ&c=y5LGzd1hT50ruE_IlUH7x8VGgWz9W0tFVWT6rSvPUKA&r=OqJOXvZGIFafgLt7Uocjlzsiwprj2_HJJ0p7HG9IsupasVjguMhbhoUfzdA5V_Qn&m=CCOIqqrapqve7SfBS7uoDgFCrVh83PSU7mN-ZblHnho&s=ehLOY9yBJ2LpM0Jnl-xWpiL5r35oVQnvoglF9U_m118&e= Below is the output form my pi. Due to the time it takes to create a PNG and the scheduling strategy it usually ends up being about a second between pictures. When I reduce my configuration to what you have ( for the timing config options ) I maintain the same pattern of taking a picture every 900 ms. Logs may help further diagnose the issue.
