From a9e00cd451f8859dad335d64cb4c77d95b6a06b3 Mon Sep 17 00:00:00 2001 From: Frank Galligan Date: Thu, 24 Oct 2013 10:33:24 -0700 Subject: [PATCH] vpxdec: Fix webm fps check. If the webm file did not have a Cues then vpxdec would fail when creating a y4m file. If there is no Cues element print out a warning and set fps to 30.
