Subject: www-client/chromium: Restore widevine support in the dev channel (47)
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=bc7b92e875db316b8b81055c21334dcd0dcbd16c;p=gentoo.git

www-client/chromium: Restore widevine support in the dev channel (47)

This includes a minimal patch to get chromium to compile. The widevine
version is reported as "unknown" in chrome://plugins. A more robust
solution should really be implemented upstream.

Tested by viewing a video on Netflix.

Based on work by Greg Turner and Ari Entlich.

Closes #37.
