Filter has an unconnected output

Question

I am using FFMPEG to merch 2 videos together with a fade effect in between. The console output shows the following error:

Filter setpts has an unconnected output

I have looked up what could be wrong, but can't find anything related to my error that helps me out.

ffmpeg -i ./temp/1900f421192fcdaf.ts -i ./temp/35c16f3debf9e730.ts -an \
    -filter_complex \
    [0:v]trim=start=0:end=9,setpts=PTS-STARTPTS[firstclip];\
    [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip];\
    [0:v]trim=start=9:end=10,setpts=PTS-STARTPTS[fadeoutsrc];\
    [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc];\
    [fadeinsrc]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1[fadein];\
    [fadeoutsrc]format=pix_fmts=yuva420p,fade=t=out:st=0:d=1:alpha=1[fadeout];\
    [fadein]fifo[fadeinfifo];\
    [fadeout]fifo[fadeoutfifo];\
    [fadeoutfifo][fadeinfifo]overlay[crossfade];\
    [firstclip][crossfade][secondclip]concat=n=3[output]\
-map ./rendered/2017-11-16_11:59:41.mp4

Thank you in advance for helping me out.

Answer 1

This error has nothing to do with setpts, but with the syntax of the parameters for complex_filter, they should be enclosed in quotes.

---

Changed:

• Enclosed filter_complex parameters in quotes
• Removed -map parameter
• Removed [output]
• Added whitespace before every line-break

---

Editted command:

Remove -report parameter if not debugging.
