Package: gscan2pdf
Version: 2.13.0-1
Severity: normal
X-Debbugs-Cc: none, Francesco Potortì <Potorti@isti.cnr.it>

If I enable the "Postprocessing / Clean up images" option with default values, I get errors from unpaper.  Here they are:

[image2 @ 0x564ee7da3540] Encoder did not produce proper pts, making some up.
[image2 @ 0x564ee7da3540] The specified filename '/tmp/gscan2pdf-EBri/SGOfFcr2Nn.pnm' does not contain an image sequence pattern or a pattern is invalid.
[image2 @ 0x564ee7da3540] Use a pattern such as %03d for an image sequence or use the -update option (with -frames:v 1 if needed) to write a single image.

The file mentioned in the second of the three error messages does not exist.

This is unpaper 7.0.0-0.1

If I downgrade to unpaper 6.1-2+b2 I get these errors instead:

[ppm_pipe @ 0x5560cbcbd500] Stream #0: not enough frames to estimate rate; consider increasing probesize
[image2 @ 0x5560cbcc3740] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead.
[image2 @ 0x5560cbcc3740] Encoder did not produce proper pts, making some up.

I can't downgrade unpaper further because that would require installing old dependencies.

I have used gscan2pdf (with unpaper) for many years, and I am sure it used to work without problems until maybe one year ago.  I also tried downgrading gscan2pdf to 2.3.0-1, the error message changes but it is always there.
