Abstract

Incompatibile with specifications and leading for sure to playback issues, for example:
- conflict in specification with a sentence containing "must"
- some parts of the specification imply constraints on specific fields
- obviously problematic values leading to playback issue on allmost all or all players

List of checks involving this severity

(content element) is (content element value for independent) but (container element for IPF) or (container element for IF) does not indicate this frame is independent.
usacIndependencyFlag is 0 for first UsacFrame inside AudioPreRoll
(container format) (container element) (container value) does not match (content format) (content element) (content value)
usacIndependencyFlag is 1 but MP4 stts or (container format) (container element for independent frame (IF)) does not indicate this frame is independent
(container format) (container element) (container field) (container value) does not match (content format) (content element) (content field) (content value)
AudioPreRoll is not present so this frame is an independent frame (IF) but (container format) (container element for independent frame (IF)) does not indicate this frame as such
auLen is 0 but preroll frame shall not be empty

channelConfigurationIndex (value) implies element order (expected channel config order)
(container format) (container element) (container field) (container value) does not match (content format) (content element) (container value) (content value)
channelConfigurationIndex (value) is used but the usacElementType sequence contains (channel config order), which is the configuration indicated by channelConfigurationIndex (expected value)
