• Crash with opencv video intitialisation

  21 November 2013, by Ingeborg

  I have the problem which is described here.

  The extension i have already set correct.
  What i have done regarding the suggestet Points on the link:

  Point 1: I have looked in my cmake file and ffmpeg, libavutil etc is all chosen.

  Point 2: I thought all files are installed automatically in usr/src if you don't change it, isn't it?

  Point 3: It is a new installation. But btw. how can i deinstall the lib?

  Point 4: Shouldn't be the problem.

  Thx in advance

  Further infos:
  Opensuse 12.3
  Opencv-2.4.3
  Qt4 Environment

  C++ Commands used last:

  VW.open(vsm, CV_FOURCC('F','L','V','1'), 25, vidImg.size(),!(vidImg.channels() == 1));

• checkasm: Generalize crash handling

  14 December 2023, by Martin Storsjö

  checkasm: Generalize crash handling
  This replaces the riscv specific handling from
  
  7212466e735aa187d82f51dadbce957fe3da77f0 (which essentially is
  
  reverted), with a different implementation of the same (plus a bit
  
  more), based on the corresponding feature in dav1d's checkasm,
  
  supporting both Unix and Windows.
  See in particular the dav1d commits
  
  0b6ee30eab2400e4f85b735ad29a68a842c34e21,
  
  0421f787ea592fd2cc74c887f20b8dc31393788b,
  
  8501a4b20135f93a4c3b426468e2240e872949c5 and
  
  d23e87f7aee26ddcf5f7a2e185112031477599a7, authored by Henrik Gramner.
  The overall approach compared to the existing implementation for
  
  riscv is the same; set up a signal handler, store the state with
  
  sigsetjmp, jump out of the crashing function with siglongjmp.
  The main difference is in what happens when the signal handler
  
  is invoked. In the previous implementation, it would resume from
  
  right before calling the crashing function, and then skip that call
  
  based on the setjmp return value.
  In the imported implementation from dav1d, we return to right before
  
  the check_func() call, which will skip testing the current function
  
  (as the pointer is the same as it was before).
  Other differences are:
  
   Support for other signal handling mechanisms (Windows
  
    AddVectoredExceptionHandler)
  
   Using RtlCaptureContext/RtlRestoreContext instead of setjmp/longjmp
  
    on Windows with SEH
  
   Only catching signals once per function - if more than one
  
    signal is delivered before signal handling is reenabled, any
  
    signal is handled as it would without our handler
  
   Not using an arch specific signal handler written in assembly
