+gst-ffmpeg: lavf: compute probe buffer size more reliably.
+
+The previous code computes the offset by reversing the growth
+of the allocated buffer size: it is complex and did lead to
+inconsistencies when the size limit is reached.
+
+Fix trac ticket #1991.
+(cherry picked from commit 03847eb8259291b4ff1bd840bd779d0699d71f96)
