Summary

0002948: Rendering crashes at a still image

Description

Hi all,
my rendering crashes at the first frame of a still image. Strangely enough, if I use the same sources, project, and kdenlive on another PC, it does not crash.
Also, if i select only the zone of the crash, it does render fine.

I'm running Debian Sid. The kdenlive Version 0.9.3 (rev. c3fa0f6)/melt 0.8.7/ffmpeg git-2013-01-13-a6e4796 are frome the build script.

In gdb, the crashing thread shows
the following, with s pointing to NULL afaics

Program received signal SIGSEGV, Segmentation fault.

Additional Information

This is a rather large project with lots of clips and stills, so it's quite difficult tor reproduce. But If I can be of assistance to narrow his down, I'd gladly help.

(0009104) sys3175 (reporter) 2013-01-18 20:27	The command line I used for this was gdb --args melt /home/hartmut/kdenlive/scripts/suedtirol-01-hd-x200s_002.sh.mlt -profile atsc_1080p_25 -consumer avformat:/home/hartmut/Videos/suedtirol-2012-hd.mp4 progress=1 f=mp4 hq=1 acodec=aac ab=128k ar=48000 pix_fmt=yuv420p vcodec=libx264 crf=23 maxrate=12000k bufsize=1835k preset=superfast tune=film aspect=@16/9 threads=10 real_time=-1 verbose=1 and I sourced bin/kdenlive_env before calling this.

(0009113) j-b-m (administrator) 2013-01-21 11:28	Can you try to make a copy of your .kdenlive project file and remove everything from the project except the clip that causes the rendering crash. Does rendering also crash with this modified project? If it does, could you archive the project (in Kdenlive's Project menu > Archive Project, then select the "Compressed archive" option)? It will create a .tar.gz file with the project file and all necessary clips. You can then attach the tar.gz here or mail it to me - jb at kdenlive org - so that I can try to reproduce..
