When trying to convert jpg into webp I get on some images an error 0x0x0 impossible to open

the jpg are not read only

any idea ?

do you use 'multi core'?

I have a Mac pro Quad-Core Intel Xeon, a old one but running very well

I think Pierre is asking whether you have selected the option on the Output tab to use more than one core, a check box and slider at bottom left, if that option is available in the Mac version...

I get the same error with or without 'Use CPU Core's', only some files are converted and I get thousands of errors.

If possible could you upload an example JPEG file that doesn't convert to WEBP for Pierre to test, 2MiB the current forum attachment limit...

there is no example jpg exactly, one time it works one time not, I proposed Pierre to look the problem with teamviewer

Some things you could try if you wish, while waiting for a response from Pierre: the developer of all XnView software, who has a heavy workload at present:

On the Settings tab, do you have Load format settings... > Ignore read errors enabled?

Are you sure the failures are random, and not related to particular JPEGs?

Does the same issue occur when converting to formats other than WEBP, PNG for example?

Does the issue occur when using XnConvert 1.79, the version before multiple core support was introduced?

I have only the last version , I dont know the one before
it seems that error occurs after more or less 2500 files
yes same error if I try to convert into png

Thanks:

XnView software seems less tolerant of malformed files than some other software, so that rather hidden setting can be relevant.

But if the error normally occurs only after successfully reading around 2500 files, that seems significant and could be useful information for Pierre.

Another question: are the files being read all on your computer hard drive?

Although it might be inconvenient, downloading and installing XnConvert 1.79 [scroll well down] which only uses a single core, might also provide useful information.

Ignore read error is on
all files have read/write permission and the containing folder too

ill cannot find 179 version for MAC the appleimage format is unknown on my mac

There is a download link for Mac on this page, but whether the link is still to 1.79, or to 1.80 now that it has been released, I'm not sure...

1.79 works perfectly , very fast and not a single error

thanks a ton

Progress!

Thanks for your investigation, so the problem you originally reported seems to be related to the multi-core support added in 1.80...

but you don't use 'multi core', right?
