Hello, I was debugging an issue with a video file containing an invalid display matrix, probably produced by a non conforming software.
The content of the matrix is: 00000000: 0 65536 0 00000001: -1 0 0 00000002: 0 0 1073741824 The -1 (stored as 4294967295) was probably a 1 shifted 32 times instead of 16. The problem is that this value is bypassing the validation check in the code below, and the resulting computed SAR value becomes 1:65536. This change interprets extremely low entries as invalid and makes sure to skip them in the SAR computation. This passes fate, but I haven't been able to test this extensively. Please see the attached patch, any feedback or better solution is welcome. -- Vittorio
