Hello, I wanted to test what the Vid. Stab Deshake effect does and here is what happened: - I dragged a video clip on the timeline - I dragged the Vid. Stab Deshake effect from the Effects list to the clip on the timeline - Kdenlive crashed: segmentation fault (core dumped) kdenlive I reproduced the same event every time I tried to apply this effect on a clip.
Created attachment 108808 [details] backtrace Here is the backtrace I get following the bug report manual.
It crashes in libvidstab.so when parsing motions file, not sure if that is created by MLT. I suggest to report this issue to MLT developers via https://github.com/mltframework/mlt/issues Relevant part of the backtrace: #0 0x00007ffff03c6cdf in __GI__IO_vfscanf () at /usr/lib/libc.so.6 #1 0x00007ffff03d60c6 in __isoc99_fscanf () at /usr/lib/libc.so.6 #2 0x00007fffc40babbd in restoreLocalmotion () at /usr/lib/libvidstab.so.1.1 #3 0x00007fffc40bad96 in vsRestoreLocalmotions () at /usr/lib/libvidstab.so.1.1 #4 0x00007fffc40bb128 in vsReadFromFile () at /usr/lib/libvidstab.so.1.1 #5 0x00007fffc40bb1cb in vsReadLocalMotionsFile () at /usr/lib/libvidstab.so.1.1 #6 0x00007fffbed9e7d7 in () at /usr/lib/mlt/libmltvidstab.so #7 0x00007ffff71d5b52 in mlt_frame_get_image () at /usr/lib/libmlt.so.6 #8 0x00007ffff71ec70b in () at /usr/lib/libmlt.so.6 #9 0x00007ffff71d5b52 in mlt_frame_get_image () at /usr/lib/libmlt.so.6 #10 0x00007ffff6fbb27e in Mlt::Frame::get_image(mlt_image_format&, int&, int&, int) () at /usr/lib/libmlt++.so.3
I thought libvidstab.so to be working as expected, because I think I am using it through ffmpeg and it works well. $ ffmpeg -i source.MP4 -vf vidstabdetect=shakiness=8:accuracy=15:result="transforms.trf" -f null - $ ffmpeg-i source.MP4 -vf vidstabtransform=smoothing=60:input="transforms.trf",unsharp=5:5:0.8:3:3:0.4 out_stabilized.mp4 This works without any crash. I am not 100% sure this is using libvidstab.so but it looks like it does to me. With these informations, do you still think this should be handled by MLT? Thanks
