NOT Recognize only by extension (for videos also)

George2006 · Post by **George2006** » Sun Oct 21, 2007 10:05 pm

I have a request, simllar with what is discussed in this thread:

http://newsgroup.xnview.com/viewtopic.php?t=5588

The problem is my videos from my Nokia phone have the extension .mp4, but it seems to me that is actually .3gp format (thus renaming the extension to .3gp shows a thumbnail).

I don;t want to rename the files because other programs (including my TV set that has a SD card reader build-in, sees the videos and plays them only with the mp4 extension)

So my request is to ignore the extension for the recognition of the actual format, not only in the pictures but in videos also OR any other solution you can make up, without renaming the original files.

Thank You.
Great Job, so far.

Thank you guys for your quick response

but unfortunately this doesn't seems to be the solution to my problem.

I already had this option checked and the MP4 extension at place.

I include an image that shows exactly what I mean:

When I let the original extension (MP4) I get the plain icon for this filetype.
XnView ignores the fact that this file is actually a 3gp (as Gspot and similar programs recognize).
Only when I rename it to 3gp the file shows a proper thumbnail.

See the before/after photo. This is the same file.
As MP4 shows the icon, as 3gp shows the thumb.

Any (additional) help would be appreciated!

Hello,
But this solution was only to hide the related thumbnails
with also:
View\filter by\custom
and uncheck custom files(*) at the bottom:" thumbnails" and if needed "other" too.
to hide at least your *.mp4 blank thumbnails.

But if you want to see your *.mp4 thumbnails as your *.3gp, I think (maybe) , in your case, it is a codec association issue or maybe a bug in xnview???
"if (thus renaming the extension to .3gp shows a thumbnail). "

My problem is that XnView doesn't build thumbnails because it looks at the extension. I don't have problems with codecs. I have almost 500 installed (Gspot states that) and all my clips are playing fine.
The problem is obviously with XnView.

In my 1st post you can see a related topic:
http://newsgroup.xnview.com/viewtopic.php?t=5588

In that post the author of Xnview says that the option
Options > Browser > File list > Recognize only by extension
is for pictures only.

So that's why I posted the "suugestion" for this option to include videos.

Any other solution? TIA.

For videos, XnView check extension. For pictures, xnview can read header to find the format...

thanks for this precision Pierre, about this current Xnview version (1.91.6).

It does? o.O Whenever I have a picture in a folder with a wrong extension, it's always given a blank icon and won't open. (Showing properties sometimes does show the real format though, for whatever good that does.)

Do you have enabled 'based only on extension'?

Oh, I guess that option is on by default. Well, I turned it off, so I'll see how it goes.

I'm having a similar problem:

I have some 4:2:2 YUV pictures with the extension .yuv8. Even when I uncheck "Recognize only by extension", the thumbnail of these pictures will not display. However, as soon as I simplify the extension of the file to .yuv, the thumbnail appears perfectly.

I'd like to leave the existing extensions in place (if only to differentiate yuv16 from yuv8 files), but it seems that I can't do this if I want XnView to display them.

Is there any workaround for this? Am I missing something?

Thanks.
