[FFmpeg-user] Issue timelapse fps slowing down until reach 0 fps - thread_queue_size

The idea behind this is: From a list of photos I generate a timelapse add a
logo in the first few seconds and fade out. Also I have a audio fading in
in the beginning of the video and out in the end.

I already added thread_queue_size 512 but didn't work. I will try to check
your rules Moritz, if you could give an example within the command would be
great. Thanks

This is the full output:
