• Component: Media
• Status: RESOLVED FIXED

[Jean-Yves Avenard [:jya]]

leaked stack is this one:

6   com.apple.WebCore                     0x1b3bc9e5c WTF::BlockPtr<void (int, unsigned int, __CVBuffer*, CMTime, CMTime)> WTF::BlockPtr<void (int, unsigned int, __CVBuffer*, CMTime, CMTime)>::fromCallable<WebCore::WebCoreDecompressionSession::decodeSampleInternal(opaqueCMSampleBuffer*, bool)::$_2>(WebCore::WebCoreDecompressionSession::decodeSampleInternal(opaqueCMSampleBuffer*, bool)::$_2)::'lambda'(void*, int, unsigned int, CVBuffer*, CMTime, CMTime)::invoke(void*, int, unsigned int, __CVBuffer*, CMTime, CMTime) + 248
5   com.apple.CoreMedia                   0x1991cbcac CMVideoFormatDescriptionCreateForImageBuffer + 848
4   com.apple.CoreMedia                   0x1991a7e10 CMVideoFormatDescriptionCreate + 128
3   com.apple.CoreMedia                   0x1991a8520 FigDerivedFormatDescriptionCreate + 740
2   com.apple.CoreFoundation              0x18cd429b0 _CFRuntimeCreateInstance + 880
1   libsystem_malloc.dylib                0x18cb136dc _malloc_zone_malloc + 64
0   libsystem_malloc.dylib                0x18cb2bc48 _malloc_zone_malloc_instrumented_or_legacy + 152 

Which I think is this code: https://searchfox.org/wubkat/rev/9235b1a61373f4234edd48dd00c30a0fda85faba/Source/WebCore/platform/graphics/cocoa/WebCoreDecompressionSession.mm#229-230
