resolves #8992

Workaround for crashed test:

[ RUN      ] Videoio_Video_parallel_writers_and_readers.accuracy
incorrect codes
*** Error in `/build/precommit_linux64/build/bin/opencv_test_videoio': free(): invalid pointer: 0x00007fc301fdf240 ***
Process returned: -11

or

[----------] 1 test from Videoio_Video_parallel_writers_and_readers
[ RUN      ] Videoio_Video_parallel_writers_and_readers.accuracy
Process returned: -11

Can be reproduced with Ubuntu 14.04 (libav 9.20).
Ubuntu 16.04 (ffmpeg) is fine.
