Is there a filepath/filename length limit in the UI? #2070
Description
I want to use the following for "image file name":
camname_%Y-%m-%d/camname_%Y-%m_%d_%I-%M-%S-%p_%q
and this for "movie file name":
camname_%Y-%m-%d/camname_%Y-%m_%d_%I-%M-%S-%p
but upon clicking the apply button, motioneye throws up the message
"Make sure all the configuration options are valid!"
When I look at the fields, they have the little red warning icon / mouseover text "special characters are not allowed in the filename", but I'm pretty sure I'm not using any because:
a) if I delete some from anywhere, eventually the warning vanishes
b) if I manually populate the filename in camera-1.conf, it works fine. files are saved with the right names in the right place.
Might be related to #1497 but I dunno.
Thanks,
Matt

Do you need 2 camname_'s in the filename? I use something like:
camname/jpg/%Y-%m-%d/%H-%M-%S-%q and camname/mp4/%Y-%m-%d/%H-%M-%S
or
camname/%Y-%m-%d/jpg/%H-%M-%S-q and camname/%Y-%m-%d/mp4/%H-%M-%S
to split them up.
Also, what value is %p? It's not in the tool tip, and may not be supported.

I suppose I don't need two camnames, it just makes it easier to run scripts on multiple files, but that doesn't really answer my question.
%p is AM/PM. Here's some examples taken just now:
I edited my camname but you can see that the filenames work just fine.

Unless your camera name includes special characters, I can't see any reason why a 60+ character path name (expanded) should cause a problem.

That's the thing.. it's not causing a problem anywhere but in the motioneye interface. I can't apply any changes because it gives me the error above.

I just did a copy/paste of your filenames above (literally camname in it)
Red warning.
If I change the %I for %H and remove the -%p it accepts it in the web interface. Since they are not mentioned in the WebGUI tool tip, there may be a filter for valid variables that isn't including those. I can tag as a request for 'enhancement' for the modification to allow them if you'd like.

The validator for filenames has this matcher as the part of it:
%[CYmdHMSqv]. Edit: and there's no lenght limitation.So, that's why
%land%pare not valid for the field. There's no real technical reason for that I guess (and the reason might be that those are not mentioned in Motion docs, either, they get inherited fromstrftimeformat specifiers). It would be trivial to add those two.Myself I do find using 12 hour notation in file/path names terrible since it breaks up sorting by the file name (mixes day and night files), but then again I'm also used to 24 hour time notation.

@zagrim many thanks for the clarification, as always.
Allow 12-hour/AM-PM strftime specifiers (%I, %p, %l) in file names (#…

Done with #3377 for next release, thanks to @JamBalaya56562!
