(0009374) farid (reporter) 2013-03-09 22:42	i also got this: (gdb) backtrace #0 0x00007fffd7d2f850 in ?? () #1 0x00007fffd6f2e54e in av_lockmgr_register () from /usr/lib/libavcodec.so.54 0000002 0x00007ffff2895e51 in __run_exit_handlers () from /usr/lib/libc.so.6 0000003 0x00007ffff2895ed5 in exit () from /usr/lib/libc.so.6 0000004 0x00007ffff287fa1c in __libc_start_main () from /usr/lib/libc.so.6 0000005 0x0000000000455ef1 in _start ()

(0009375) farid (reporter) 2013-03-09 23:29	maybe this also will help.

(0009387) zico (reporter) 2013-03-18 01:12	I experience the same bug as well. Bug from post 0009374 happens on exit of kdenlive as well as on every render. I happened somewhere when Arch upgraded ffmpeg as well as some other packages. I can however not really isolate the problem to a single package and downgrading them usually creates even more issues. I am almost thinking this has something to do with Arch itself but the backtrace points to mlt (0.8.8) and ffmpeg (1.1.3 and 1.2).

(0009392) nboichat (reporter) 2013-03-20 10:02	I managed to trace down the bug related to the last backtrace (av_lockmgr_register). https://sourceforge.net/p/mlt/bugs/192/ [^] That one is a melt bug.

(0009393) nboichat (reporter) 2013-03-20 10:07	For the errors that shows "Undefined constant or missing '(' in 'dct8x8'", and " Encoder did not produce proper pts, making some up. ": These errors happen anyway, whether melt crashes or not. It's just that when melt crashes they are displayed to you. Otherwise they aren't.
