Are you able to build MLT > from git yourself and test it? After uninstalling melt package I used from apt repository, I've tried to build MLT from git but I have errors. Here is the configure command I used (I think it's yours ;p ): ./configure --enable-gpl --disable-mmx --avformat-swscale --avformat-static=/root/ffmpeg --avformat-ldextra="-lmp3lame -lfaad -lfaac -lxvidcore -lx264 -lvorbis -ltheora -lvorbisenc -logg -lbz2" Which returns me the following: Configuring framework: Configuring modules: Configuring modules/avformat: Configuring modules/core: Configuring modules/dgraft: Configuring modules/dv: - libdv not found: disabling Configuring modules/effectv: Configuring modules/feeds: Configuring modules/frei0r: - frei0r plugin disabled.

That seems backwards. I was very dependent of Aptitude repositories. On my newer production server, I first used the last Ubuntu official repository (http://fr.archive.ubuntu.com/ubuntu/ lucid/universe Packages) to install melt v0.5.4-1 but I had the "Segmentation fault" error. Then I uninstalled the melt package (apt-get purge, then I check with "dpkg -l | grep melt" to confirm the package has been successfully uninstalled) and tried with the launchpad repository (that someone from this mailing list once advised me to use).

So, still on my production server, as I didn't succed in building MLT from git, I did again "apt-get install melt" from official Ubuntu Lucid repository. I currently have melt v0.5.4-1 Here is the backtrace I have with gdb: http://www.vercoustre.com/gdb-melt.txt > >> Finally, here is my command line: >> # command beginning >> melt -debug color:black in=0 out=1549 length=1550 \ >> \ >> -track -blank 75 >> avformat:/home/www/framework/files/recordings/29_20100617_192359_second.wmv >> audio_index=-1 in=75 out=1474 length=1550 \ >> -track avformat:/home/www/framework/files/recordings/29_20100617_192359.wmv >> out=1549 length=1550 \ >> -track colour:black in=0 out=99 \ >> -track colour:white in=0 out=74 \ >> -track /home/www/framework/files/recordings/logo.png ttl=1550 in=0 out=1549 \ >> \ >> -transition composite geometry=170,30:300x300 progressive=1 a_track=4 >> b_track=5 in=0 out=54 \ >> -transition composite:170,30:300x300 end=10,290:60x60 progressive=1 >> a_track=4 b_track=5 in=55 out=64 \ >> -transition composite geometry=10,290:60x60 progressive=1 a_track=3 >> b_track=5 in=65 out=74 \ >> -transition composite geometry=10,290:60x60 progressive=1 a_track=4 >> b_track=5 in=65 out=74 \ >> -transition luma softness=0.1 reverse=1 a_track=3 b_track=4 in=65 out=74 \ >> -transition composite geometry=10,290:60x60 progressive=1 a_track=0 >> b_track=5 in=65 out=1549 \ >> -transition luma softness=0.1 reverse=1 a_track=1 b_track=3 in=75 out=99 \ >> -transition composite geometry=160,0:480x360 progressive=1 a_track=0 >> b_track=1 in=75 out=1549 \ >> -transition composite geometry=-180,10:180x135 progressive=1 a_track=0 >> b_track=2 in=0 out=89 \ >> -transition composite:-180,10:180x135 end=0,10:180x135 progressive=1 >> a_track=0 b_track=2 in=90 out=99 \ >> -transition composite geometry=0,10:180x135 progressive=1 a_track=0 >> b_track=2 in=100 out=1549 \ >> \ >> -consumer >> avformat:/home/www/framework/files/recordings/29_20100617_192359_mixed.mp4 >> acodec=libfaac ab=92k vcodec=libx264 >> vpre=/usr/share/ffmpeg/libx264-hq.ffpreset minrate=0 b=1024k b_strategy=1 >> subcmp=2 cmp=2 coder=1 flags=+loop flags2=dct8x8 qmax=51 subq=7 qmin=10 >> qcomp=0.6 qdiff=4 trellis=1 aspe...@16/9 s=640x360 >> # command end >> > > Are you certain your build of ffmpeg and libs has enabled libfaac?
