|Target Version||Fixed in Version|
|Summary||0000148: File Filters are Incorrect|
|Description||When creating a slideshow from a series of pictures the JPEG file filter is listed as "*.JPG". This is incorrect specifically for JPEG's as "*.JPEG" is also a valid filter (it is in fact the "proper" extension). This is incorrect in general as file-filters are a Windows-only concoction and make little or no sense on a Linux system where fingerprinting and MIME types are used to identify a file's format.|
Therefore, proper design requires that file filters should only suggest a file listing - not restrict a user to that list.
|Additional Information||Compiled on Gentoo.|
Same additional info as issue 0000145.
|Tags||No tags attached.|
Update on this bug:
ffmpeg revision 15426
mlt revision 1182
mlt++ revision 1182
kdenlive revision 2413
The filter now identifies both jpeg and jpg in any case (including e.g. JPeG), but fingerprinting does not appear to work.
There is still no option for the user to provide his own extension.
Note to developers: I have acknowledged this issue, because I believe it deserves to be either confirmed, or closed (wont-fix).
This is an MLT issue. Currently, the MLT image producers (qimage and pixbuf) can only recognise image lists based on a wildcard (*.jpg).
I modified Kdenlive to be consistent with that (do not show *.jpeg anymore).
This issue requires some work on MLT image producers. We could either try to implement a mimetype detection in MLT or add a feature to pass a list of files to the image producers, so that the mime filtering could be done by Kdenlive (easy to implement)...
Keep this issue open, let's hope someone finds time to work on it.
|Moving issue to version 0.7.1 - I don't think anyone will be able to work on it for Kdenlive 0.7.0 (requires work on MLT).|
Re: "fingerprinting and MIME types are used to identify a file's format"
According to whom? Where except by the 'find' utility? What does KDE do?
File extensions are still prevalent because they are extremely pragmatic. I am not opposed to improving the system beyond file extension matching as long as it does not considerably degrade performance.
In response to myself, I am thinking freedesktop.org shared-mime-info is the way to go:
