Subject: fix pipe support on windows
X-Git-Tag: 1.0_branch~809^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c377bf0eec4ab3862e41f7db534e9d3070b0bed7;p=profile%2Fivi%2Flibvpx.git

fix pipe support on windows

STDIO streams are opened in text mode by default on Windows. This patch
changes the stdin/stdout streams to be in binary mode if they are being
used for I/O from the vpxenc or vpxdec tools.

Fixes issue #216. Thanks to mw AT hesotech.de for the fix.
