Summary0000487: empty slideshows result in a crash
Descriptionwhen trying to load as a slideshow (not through the "add slideshow" interface since it forbids this, but there are other ways) a folder without images that match the given wildcard, kdenlive crashes
Additional Informationit could be checked by kdenlive, but it should be possible to "leave as placeholder" an empty slideshow clip

crash report:
Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread 0x2b401100 (LWP 100307)]
0x2ba18b53 in load_image (producer=) at producer_sdl_image.c:153
153 image_idx = ( int )floor( ( double )position / ttl ) % mlt_properties_count( filenames );

is % mlt_properties_count( filenames ) the problem (since it should be equal to % 0)?
TagsNo tags attached.

 Hi xzhayon,

You mention that there "are other ways" to load a slideshow. Could you provide step by step instructions on how to recreate this, as the only user visible way of creating a slideshow is through the interface.

If you can do this I can try and confirm this bug.

Thanks!

 move the folder containing the images and load the project: a dialog will appear asking you to "search manually/leave as placeholder"
if you search it and select a folder without (for example) *.jpg images you'll get a crash
if you choose to leave as placeholder you'll get a crash

also, if you delete the images and leave the directory empty, and then load the project, you'll get no errors, but it will crash

 I just submitted a patch on MLT's mailing list that will solve the MLT crash and allow clip as placeholder

 management of this situation improved, but it's still crashing. here's what i get when i:

1. rename the directory of the slideshow
2. open the project
3. select "keep as placeholder" when prompted about the slideshow

...a dialog saying "Clip xxx/.all.jpg is invalid, will be removed from project." and the following crash:

kdenlive(18174) Render::getFileProperties: // LOOKING FORÂ H264 on: 0

unfortunately i can't get a backtrace, the stack is corrupt..
it seems i can't reproduce this 100% of the times...

 fixed in revision 3265 introducing placeholders management (those, unfortunately, are still crashing: opening a new issue for that)
