[msmeissn]

Describe the bug

--get-config imageformat

returns

Label: Image Format

Name the camera

Canon EOS M10

libgphoto2 and gphoto2 version

2.5.31.1 current GIT vs 2.5.31

To Reproduce
Steps to reproduce the behavior:

gphoto2 --get-config imageformat

[msmeissn]

eos.log 2.5.31 logfile
eos-new.log 2.5.31.1 logfile

[msmeissn]

@axxel if you could take a look perhaps

[msmeissn]

in 2.5.31 it is coded as 0x200
in 2.5.31 it is coded as 0x2ff

[msmeissn]

i now emit the default even if the ENUM is empty

[msmeissn]

but perhaps axxel has a better fix

[axxel]

Based on your fix, it seems the problem is that the M10 reports a current value that it actually does not enumerate as a valid value?

[msmeissn]

Yes, it does not return an enumeration, but a value.

Might depend on the camera mode, but the camera is currently in Manual Mode

[axxel]

Apart from the code duplication in your fix, I don't see a better approach then. I'll post a cosmetic fix for that at some point in time.
