Can you use gdb and do a backtrace ?

morphogo picture morphogo on 13 Oct 2019

yes the backtrace macOS throws (clicking on report) would be helpful. does it also occur with --vo=gpu? could you try a commit before https://github.com/mpv-player/mpv/commit/6d0f0546ee851f4106438c5b92c8d1d152937ea7, eg 2b19a7c964b821945e3ea06cfa81c1c064f2504d?

Im not a programmer. I know how to use terminal and build from source. Thats my limit

vo=gpu

(gives this error)

Warning: option --video-aspect was replaced with --video-aspect-override and might be removed in the future.

(+) Video --vid=1 () (h264 320x240 29.970fps)
(+) Audio --aid=1 --alang=eng () (opus 1ch 48000Hz)
[vo/gpu] opengl cocoa backend is deprecated, use vo=libmpv instead

Im using Catalina. Im basically trying to use the latest FFmpeg and latest mpv. Without home-brew installation.
Which is the trouble I think.

I have lldb on my Mac. I have no idea how to backtrace with it.

Maybe give me instructions. Id gladly do it.

See the LLDB documentation on:

  1. Loading an application in it.
  2. Starting the application you've loaded.
  3. When it crashes, within lldb do bt all.

That should do it unless you specifically disabled debug symbols. When the application gets loaded into lldb it should tell you if it was able to load symbols or not.

jeeb picture jeeb on 13 Oct 2019

i don't see an error, just warnings. so --vo=gpu works?

the backtrace should come automatically when an app crashes on macOS. no programming skills required.

otherwise this:

lldb mpv
(lldb) run /PATH/TO/FILE.mkv --no-config
----wait for crash----
(lldb) bt
(lldb) bt all
----copy the output----

most helpful right now for me would be if you could confirm if the mentioned commit is the offending change, otherwise the backtrace.

Thanks

No , the vo=gpu did not work. I got the segmentation fault error. Anyway, thanks for the shortcuts on lldb. I did what you said.

here is the terminal read out

could you try with xcode 11, not the beta, instead of the command line tools? just download xcode and use this command:

sudo xcode-select -s /PATH/TO/Xcode.app

to revert:

sudo xcode-select -s /Library/Developer/CommandLineTools

~also before switching~ (okay it's clang-1100.0.33.8, from your log), please paste the output of clang --version. same for after switching.

maybe it's how I installed FFmpeg? I used this to install with everything;
brew install $FFMPEG_TAP_NAME/ffmpeg $(brew options $FFMPEG_TAP_NAME/ffmpeg | grep -vE '\s' | grep -- '--with-' | tr '\n' ' ')

I also get

ss@sss-iMac ~ % ffmpeg
zsh: segmentation fault ffmpeg
ss@sss-iMac ~ %

yes, we had a little chat on irc and the actual segfault is most likely within ffmpeg or/and its libraries. they have to be compiled with the same clflag i posted above.

another workaround, supposedly, is to build everything with MACOSX_DEPLOYMENT_TARGET=10.14.

ideally apple fixed their shit, it has been reported to them since august.

since it has been reported to apple.
