Subject: typefindfunctions: Reduce XML typefinder minimum data size from 64 to 32 bytes
X-Git-Tag: 1.22.0~82
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=54ff9b2b5f2d72f5f6f98acd65d8ebf7375e73b9;p=platform%2Fupstream%2Fgstreamer.git

typefindfunctions: Reduce XML typefinder minimum data size from 64 to 32 bytes

64 bytes makes the typefinder fail on very small XML documents on which
it succeeded previously.
