Assertion fctx->async_lock failed at libavcodec/pthread_frame.c:172
Аварийный останов

but unfortunately log ends like this ...


clr async lock
./cin() [0x8c04a07]
./cin(ff_thread_flush+0x32) [0x8c06012]
./cin(avcodec_flush_buffers+0x109) [0x8cff139]

./cin(_ZN6FFMPEG6deco

and nothing past this .. :/

Lets create another thread for this specific problem....

Because it hit me randomly on file load :/

    split resource_thread update into separate audio/video threads, boxblur layout tweaks

    mailmap: add entry for myself


Configure line:

LDFLAGS=-L/usr/X11R7/lib setarch i686 ./configure --prefix=/usr --with-git-ffmpeg=https://git.ffmpeg.org/ffmpeg.git --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib --with-ladspa-build --with-opus --with-nv --enable-opus --with-jobs=4 --with-booby --build=i486-slackware-linux build_alias=i486-slackware-linux CC="ccache gcc" CFLAGS="-O3 -march=i686 -mtune=i686 -D__STDC_CONSTANT_MACROS" LDFLAGS="-L/usr/X11R7/lib -ldl -L/usr/lib" CXX=clang++ CXXFLAGS="-O3 -march=i686 -mtune=i686 -D__STDC_CONSTANT_MACROS" --no-create --no-recursion --with-commercial  

yeah, quite aggressive, I know ....

Action:
1) open program
1.1) Set load strategy to 'Create resources only'
2) try to load my KARA... .mkv file ('O' then navigate to folder where file is
 and the doubleclick on it - only resource should appear, timeline still in default state - 3 tracks,
one for video, 2 for audio)
3) drag file from Resources on timeline.
If it loads correctly - undo loading, and try again.
Eventually it will hit this assert.

Thing is, I was unable to make it assert with ffmpeg.patch provided :/ (on very same sw and hw)
may be patch slows down all those threading operation enough for assertion to be avoided ?
