I pulled the ffmpeg command myself. Here is the timing:

So it takes ffmpeg 4 minutes to process my 19 GB video file. Can you make this
timeout configurable rather than static 30s ?

--- Comment #4 from Anton Gubarkov  ---
Can you share the ffmpeg command template so I could time my audio thumb
creation outside kdenlive? I usually shoot performance of approx 60-100 minutes
which results in a file 12-19 GB (FHD@50p).

If FFmpeg audio thumbnails fail, switch to MLT audio thumbnail (slower but
safer)

Hmm, I see there is a 30 seconds timeout for the audio thumbnail creation, and
after that the process is killed. Any chance that you hit this delay ?
