 You're right, workaround works fine, my mistake, ignore
 failure_with_threads_1.mp4.

 Using threads=1 option improves output a little but doesn't fix the issue.
 You can see the output file
 [https://trac.ffmpeg.org/attachment/ticket/7583/failure_with_threads_1.mp4
 failure_with_threads_1.mp4].

 By the way, thanks for trying to help me but I never used **threads**
 option before and [https://ffmpeg.org/ffmpeg-filters.html FFmpeg Filters
 Documentation] does not list any **threads** option for filters used so I
 googled your **threads=1** recommendation. All search results from first
 page corrected **threads=1** as **-threads 1**. This is why I tried using
 **-threads 1**. Just wanted to let you know.
