Open kevleyski opened 4 months ago

kevleyski commented 4 months ago

Hi this looks to be a recent issue I have latest greatest macOS Sonoma, brew install ffmpeg, I'm consistency hitting this (I'll double check with latest SDL lib, but putting it here sos others find it)

zsh: segmentation fault

If I comment out the call to resetCursorRects ffplay is good (SDL2 branch)

./src/video/cocoa/SDL_cocoawindow

Could be Apple's bug Sonoma 14.4.1 (23E224)

What's your ffplay command line?

What's your ffplay command line?

I found it didn't matter so I didn't provide an example

Anything that would cause a window to show, which is pretty much anything, image, video, lavfi test source it doesn't matter

Heya @kevleyski - could you capture a sysdiagnose soon after this happens and post here or send to natbro@apple.com, or file a feedback (https://feedbackassistant.apple.com) soon after (this will automagically grab system traces). Neither Sam nor I are able to reproduce this from just the direct API calls, so there may be something more to the window and circumstance which a full trace would help us uncover.

@kevleyski Do you have DYLD_LIBRARY_PATH set? If DYLD_LIBRARY_PATH is set to a directory that contains a libpng.dylib (or likely libjpeg.dylib, libgif.dylib, libtiff.dylib, libjp2.dylib), ImageIO will load that libpng instead of its own, and then crash since it's the wrong library. DYLD_FALLBACK_LIBRARY_PATH is safer, and doesn't have this issue.

Here's a test app to show the crash: test.c.txt

:wave: @natbro I filed FB13800881

I'm my case I'm running vanilla Homebrew install of FFmpeg (on an Intel MacBook running latest patches of Sonoma, for me it's a recent issue)

I tried a few versions of FFmpeg including latest greatest from their git, it's not FFmpeg as far as I can tell causing this but I can try setting the dynamic library path for the other libs

The call stack doesn't seem to show problems from PNG etc but agree it's good to eliminate any cause/effect

Yeah libpng won't show up in the call stack, ImageIO crashes trying to call a function from its own libpng which doesn't exist in a Homebrew libpng (or could be a libtiff, libgif, libjpeg, etc.):

If you run echo $DYLD_LIBRARY_PATH at a terminal, does it print anything? Can you try compiling/running the test code I attached?
