It doesn't hang but it makes my pc unresponsive for a long time, even after I close rage. FWIU there should be a limit in how much cpu the thumbnailing processes can take, or a limit in the number of thumbnailing processes which can be run at the same time, or at the very least an option to turn off thumbnailing. I understand that my PC is quite old (6 years), but I would like to keep using it as much as possible :) >>>> If it would segvs i would do it via a "bt" command in gdb, but it >>>> doesn't crash and also rage_thumb keeps running in multiple processes >>>> when I stop rage, so how should I trace its activities? >>> >>> ^^^^^ you can attach to an existing process any time. when you attach the >>> process will be paused. you can grab a bt then. you can let it continue >>> running with "c" (continue) cmd any time. you can pause it again with ctrl >>> +c in gdb an get another backtrace. switch stack frame with "fr N" where N >>> matches the backtrace number. list the code where you are at with "l". list >>> a specific line number in that file in context with "l 1234". print a >>> variable you see with "p varname" dereference a pointer (like c/c++ does >>> all the time) with "p *varname" or if its a struct geta member with "p >>> varname->member". gdb will even be able to tab complete these like a shell >>> does with files. :) >>> >>> learning gdb is a very powerful thing. you can find out so much useful info >>> about a process... :) >>> >>>>> >>>>>> Thanks >>>>>> Massimo >>>>>> >>>>>> Carsten Haitzler (The Rasterman) ha scritto il 20/08/2016 alle 05:45: >>>>>>> So here is a new release of Rage. >>>>>>> >>>>>>> It is a simple video and audio player intended to be slick yet >>>>>>> simplistic, much like Mplayer.
