AVPlayer libBacktraceRecording.dylib macOS App崩溃

Question

我正在开发一个macOS应用程序,我不时会收到一个奇怪的错误.我使用AVPlayer流式传输实时视频.一切正常,但经过一段时间的流媒体突然,应用程序崩溃与以下错误:

libBacktraceRecording.dylib`__gcd_queue_item_enqueue_hook_block_invoke:
    0x10019fe32 <+0>:  pushq  %rbp
    0x10019fe33 <+1>:  movq   %rsp, %rbp
->  0x10019fe36 <+4>:  movq   0x20(%rsi), %rax
    0x10019fe3a <+8>:  movq   0x20(%rdi), %rcx
    0x10019fe3e <+12>: cmpq   0x8(%rcx), %rax

    0x10019fe45 <+19>: popq   %rbp
    0x10019fe46 <+20>: retq

并且控制台日志中的消息如下所示:
