[FFmpeg-devel] [PATCH] tests/fate/mov: Disable fate-mov-invalid-elst-entry-count, the test does not work reliable currently

[Sasi Inguva]

i was on vacation so I missed this. sorry for the trouble and thanks for
fixing the test. This test was fixed once before
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=4ccc1ef2a3b1a22d849861423df830e110c9a4ab
.  I've no idea why only this test needs to have the "-flags +bitexact
-idct simple" while the other tests are fine.  I've used the same file as
the other tests, but just changed the Entry count atom using an Atom editor.
