From 2a0d7b1a55aff0870f6bda485cf7cb63662c2337 Mon Sep 17 00:00:00 2001 From: Ralph Giles Date: Thu, 5 Jan 2012 10:39:38 -0600 Subject: [PATCH] Reduce the default kf_max_dist to 128. The default maximum keyframe interval is 9999, or over five minutes at normal video rates. When the encoder produces streams with such a long interval seeking (with correct output) is more expensive, and live streaming is impossible. Of course the encoding application should set this parameter based on its knowledge of the intended use of the stream, but reducing the default gives better results for applications which do not.
