(Why are not testing the command line I used?)

Is -filter_complex needed for this task?
(I don't know, but it looks like a simple 
filter chain to me.)
Does it also crash if you only use the detc and the setpts 
filter?

Or, without any testing:
It is possible that detc only works for yuv / yuv420p 
while the tga decoder outputs rgb, so maybe just add 
a format filter (and merge it with scale) instead of 
pix_fmt.

Backtrace and / or sample missing.
