commit 9a285ed020220553b8c4f47883094ce8220d4086
Author: chcunningham <chcunningham@chromium.org>
Date: Wed Mar 08 21:48:56 2017

WebM support for new multipart VP9 string (behind flag)

The new string describes profile, level, bitdepth, color primaries,
eotf, matrix coefficients, full-range enable/disable, and chroma
subsampling.

Example:

  MediaSource.isTypeSupported(
    'video/webm; codecs="vp09.02.01.10.09.01.09.01.01"')

Ordering and required feilds are still under discussion, but this
reflects the latest proposal.

For HDR EOTFs (e.g. SMPTEST2084) canPlayType/isTypeSupported will
return ""/false until RenderMediaClient is made aware of whether
chrome is running with hdr output enabled.

To enable parsing of the new vp9 string in webm, use the flag
--enable-new-vp9-codec-string.

Alternatively, to enable HDR AND new vp9 string in webm, use
--enable-hdr-output

To enable parsing (and demuxing) of vp9 in mp4, use the flag
--enable-vp9-in-mp4

Update new VP9 codec string parsing

To reflect latest proposal (move chroma subsampling) and fix a bug
in parsing of level (Level 1 is "10", not "01" - multiplied by 10 to
accodate notation of fractional levels (1.1 is "11")).

Author: chcunningham <chcunningham@chromium.org>
Date: Thu Apr 06 23:56:52 2017

Add EME support for new VP9 codec string in WebM.

Now supporing "video/webm; codecs=vp09...." in calls to EME's
requestForMediaKeySystemAccess(). Must run with the following flag:
--enable-new-vp9-codec-string.

This CL does not modify existing support for "video/mp4". To enable
in MP4 run with --enable-vp9-in-mp4.

Runtime flags are checked in MimeUtilInternal ParseVp9CodecID().
