Crash in producer_get_image: index = -1

I am experimenting with latest svn version of kdenlive and mlt.
'svn update' reports revision 1601 for kdenlive and 990 for mlt.

It frequently crashes for me. Every time I have looked, it is because
'index' in producer_get_image in mlt/src/modules/avformat/producer_avformat.c
is -1. I don't know if this is a bug in kdenlive or mlt.

I most often get the crash when playing with transitions. For instance, I create
a PIP transition, click on the "down" arrow next to the "Horiz. position" number
to cause the image to move to the left, and then click-and-hold to cause the
number for keep stepping downwards, and there is a very high probability of a crash.

Another, quite different, task that quite often crashes is to have 4 clips lined
up in parallel in separate tracks, then move the cursor to a number of points
each about 20 seconds apart, and type "control-shift-W" to chop all the clips up
into little clips. Then I use "click" and "delete" to remove various sub-clips,
with the goal of creating a sequence which chops and changes between the
different clips. This will almost always crash at some point.

I'm happy to test patches, and do some debugging if you point me at what to
try.
(Thanks for a great program)

Forums:

Can you please update Kdenlive to current svn (1602) and tell me if the crash problem is fixed ?
regards

Thanks! It is certainly a lot better!
I did manage to get it to crash again, but I didn't get a stack trace (forgot --nocrashhandler) and I
don't think it is the same place. If I manage to reproduce it I get you more details.

Thanks for the quick response.

I'm still getting this crash from time to time.
It probably needs to be fixed in MLT - make it more forgiving of this error.
However, would you be able to explain what you did to make it happen less
often - that might give me some clues about how to approach it in MLT.
i.e. Is it simply some race whether one thread changes the image description
while another thread is trying to render that image, or is it more subtle than that?

Thanks,
NeilBrown

I can confirm the same bug.
Example : I razor a file, then press delete:

I worked two hours with Kdenlive today.

If I view clips using Play, Stop, etc... no crash happens.
If I move the cursor by hand, Kdenlive crashes after a few minutes, when moving around transitions.

When deleting a movie, I must be sure that the cursor is before the movie, not after.

Kind regards,
Jean-Michel
