AtomBox Studio Pro supports the following validation modules as separate options:

• AVC/H.264 Video Validation Module.
• HEVC/H.265 Video Validation Module.
• MPEG-2 Video Validation Module.
• MPEG-4 Video Validation Module.
• AAC Audio Validation Module.

The following list contains some of the QuickTime/MP4 container validation check groups used in the verification process:

• Mandatory atom/box absence check.
• Atom/Box extended size check.
• Atom/Box completeness check.
• Zero atom/box check.
• Descriptors completeness check.
• moov/mdat position index information.
• Mandatory entries absence.
• Zero entries presence.
• Header parameter values check.
• Media header information.
• Descriptors information.
• Track Header information.
• Media Duration information.

The following list contains some of the AVC/H.264, HEVC/H.265, MPEG-4 and MPEG-2 video validation check groups used in the verification process:

• Corrupted video frames while decoding.
• Valid video frame resolution check.
• Changing video frame resolution check.
• Valid FPS check.
• Changing FPS check.
• Changing Field order check.
• Changing Picture Structure check.
• Video Stream parameters information.

The following list contains some of the AAC audio validation check groups used in the verification process:

• Corrupted AAC audio frames.
• Changing header parameters.
• Valid audio header parameters.
• Junk data blocks detection.
• Audio Profile information.
• Audio Frequency information.
• Audio Channels configuration information.

The combined validation report output, containing the multiplex and all elementary streams validation information, can be exported into XML report file, having the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.

For detailed validation check list follow the AtomBox Studio documentation.
