I'm happy to provide you with an even smaller and
easier test case.
Just
1.) copy the attached tar archive "bug.2.tar"
to the /tmp directory and
2.) do what the attached video shows
$ cd /tmp
$ tar -xvf bug.2.tar
$ kdenlive bug.2.kdenlive
Select track Video 3's Affine transition
by clicking on it with the mouse
Click on the "Go to next key frame"
button.
Wait a moment for
"[mlt_pool] out of memory"
in the console.
Hi all,
Sorry for the late feedback. So I made a few tests and found some
interesting facts.
The problem seems related to frame buffer.
When setting the "buffer" property to 0 on the consumer (sdl2_audio) in
Kdenlive, the memory usage stays stable (around 500Mb).
When setting the buffer to 25 (default in Kdenlive), I get 2 different
situations:
- When using an HD 25fps profile, memory usage goes to about 700Mb
- When using a SD NTSC profile, memory usage quickly goes up to 2.3Gb.
These tests were done with the image attached in the latest email
(3800x2500 jpeg).
I will try to make more tests but wondering if the frame caching bugs
when using profile with a non integer fps profile..
Regards
jb
So,
Kingsley
