nit: supported format includes those without a leading 0 for profile or
level_id. spot-test those?

[erickung1, 2017/02/03 18:18:31]

according to Dolby Vision spec, the profile and level are reiquired and should
be two digits each. we have the negative test about such from #169~#182

Following is the part of the spec


--------------------------------------------------
[Dolby_Vision_fourCC].[Dovi_Profile_ID].[Dovi_Level_ID]

In this string:

• The [Dolby_Vision_fourCC] is a four-character value as listed in the Sample
description entry code table that indicates the codec type. This value can be
obtained from Dolby Vision sample entries, as described in the Dolby Vision
streams within the ISO basemedia file format specification.

• The [Dovi_Profile_ID] is a two-digit value representing the Dolby Vision
profile ID as listed in the Dolby Vision profiles section. This value can be
obtained from Dolby Vision configuration box, as described in the Dolby Vision
streams within the ISO basemedia file format specification.

• The [Dovi_Level_ID] is a two-digit value representing the Dolby Vision level
ID as listed in the Dolby Vision levels section. This value can be obtained from
Dolby Vision configuration box, as described in the Dolby Vision streams within
the ISO basemedia file format specification.
