Building proxies is crashing kdenlive after so many completed like something consuming memory as it goes until no memory left. Trying to build proxies for about 400 files didn't use to crash kdenlive, its a mixture of DSLR images and HD videos. It flys through the project tree doing the images but after a few videos further down the tree kdenlive crashes, even batching proxy conversion to say 4 videos at a time low down the project tree crashes kdenlive.

Anyone else experiencing problems?

Using svn on Ubuntu 11.10 64bit with either KDE or XFCE desktops.

i committed several proxy fixes last night, can you make sure you have svn rev. >=2818 and try again...

ok, I'll wait until sunabs next update then, currently on svn20111021r5975.

Just a bit more info in the meantime, when reloading the project after a crash building proxies and choosing to recover kdenlive crashes before finishing recover, so have to choose not to recover in order to open a project.

But hopefully next PPA update will include your fixes. Back soon, thanks.

hi j-b-m, just updated via sunabs svn build of today and kdenlive still crashes building proxies as described above and pretty much immediately after recovering. No change it appears. :-(

Damned! I thought I managed to fix those proxy crashes. Can you get a backtrace for these crashes (explained at the bottom of our bugs page http://www.kdenlive.org/bug-reports ?

regards

j-b-m, apologies, I think my problem is hardware related, but brought on by kdenlive. To explain, I'm using a dual xeon processor machine but it is limping by on half the RAM it should really have, some RAM has failed. So I read sometime ago that sufficient RAM per processor is a must with dual setups.

kdenlive was running 4 proxy building ffmpeg's simultaneously, I assume one per logical processor detected but perhaps insufficent RAM.

As a test I switched off Hyperthreading, so Linux see's only two logical processors, as a result kdenlive runs only 2 proxy building ffmpegs and all is well.

NO CRASHES. woot!
