 Replying to [comment:2 mkver]:
 > Can you upload the exact png that leads to this error? (If the file is
 big, you can upload it [https://streams.videolan.org/upload/ here].)


 I uploaded a ZIP with several PNG files that produce the crash. In my use
 case the crash happens when sending the data as a stream, but I just
 checked that using the PNG files as an input produces the crash too:

 {{{
 ffmpeg -i %03d.png -c:v prores_ks -y test.mov
 }}}

 I could just upload a handful of PNGs if the file is too large. The crash
 does not always happen on the same frame but it's usually within the first
 30. Just wanted to make sure there were enough of them (and I don't know
 if them being different or the same makes a difference).
