CMA - User Content Scanning

Incorrectly encoded content can cause issues with playback performance, network synchronization, and graphics engine
stability. To prevent this, the CMA automatically scans content locally on your computer (or the Axon media server) before
actually loading it. If no warnings or errors are found, the content is loaded on to the server. If warnings or errors are
found, a dialog box describes specific content problems.
Please note:
When the system is scanning content, the graphics engine may be unresponsive, playback may stutter, or other visual
glitches may be seen. Once scanning is complete - the system will resume normal operation. Scanning will begin
immediately after applying a DMX value to a user file, or upon start-up if no valid ContentRootCache is found.
Warnings are problems that will potentially cause issues with playback of the media on the fixture, but won't affect
graphics engine stability. An example would be a movie not being encoded with all I-frames or not having an End-of-
Sequence header. The CMA will allow these files to be loaded on to the server, but it will alert you to potential issues by
displaying the warnings in a dialog.
Errors are more serious problems with content that can create severe stability issues in media server software; for
example, content encoded as the wrong type of stream (Transport Stream instead of an Elementary Stream). Errors are
caused when content does not adhere to the MPEG2 encoding standard. When an error is found, the CMA will not allow
this content to be loaded on to a server at all. A dialog will describe the issue, and after dismissing the dialog, you will find
the specific file has not been loaded onto the server.
