 '''OS:''' CentOS 6.3 64-bit
 '''Build:''' ffmpeg version N-51518-g7f4b588
 '''Type:''' Burek static build, 64-bit, 20130402
 '''Obtained from:'''  http://ffmpeg.gusari.org/static/64bit/

 I am attempting to encode to encode from webM to MP4 and HLS segmented TS,
 for HLS playback).  For some webM files coming from YouTube, the detected
 framerate is 1k.  This causes the output frame-rate to also be freakishly
 high, causing the written level to be excessive (level 5.1).

 Mediainfo reads the test file to be 23.202 fps, and CFR.

 ----
 '''The exact command I used:'''
 ffmpeg -report -i RRSF49.webm shouldbeabout23fps.mp4

 ----

 I will attached the report, since it's too long.
