videocrop: Access violation reading

Submitted by Zakhar

Link to original bug (#761163)

Description

  1. DESCRIPTION:
    If set properties (left, top, right, bottom) for videocrop while pipeline playing, it crashes sometimes with "Access violation reading".

  2. HOW TO REPRODUCE:
    I ofen reproduce this bug with next several elements:
    videotestsrc ! video/x-raw, framerate=25/1, width=1920, height=1088 ! videocrop ! autovideosink

When the pipeline is on PLAYING state I set random values for videocrop properties (left, top, right, bottom) several times per second. After some time program crashes with "Access violation reading".

It can be reproduced only with one setting while playing. But that rarely happens.

It is reproduced on RGB and YUV frame format both.
