Kongqun Yang ba42fed9e5 Suppress warning messages when determining containers
- These warning messages are not useful since the code needs to
  loop through various container types to find a matching one.

Jacob Trimble a789dc6d3c Replace Nalu::InitializeFrom* with Initialize.
Replaces the InitializeFromH264 and InitializeFromH265 methods with
a single Initialize method that accepts a CodecType.  Also moves the
CodecType enum from NaluReader to Nalu.

- Sample duration wasn't scaled in TsSegmenter to calculate the current
  segment's length. So segmenting length did not always respect

Jacob Trimble a80e16bab0 Close files in Finalize for WebM segmenters.
Now Finalize() will close all the files used by the segmenters.  This
is important to allow WebMMuxer::FireOnMediaEndEvent to get the
correct size of the media file.

This also changes the WebM muxer to use 64-bit numbers for the init
and index ranges to correctly support >4GB files.

A follow-up change will replace the remaining usages of 'raw' pssh
