Ad Media Files Don't Play

Problem: Even with a valid implementation, ad media does not play.
The Ad media creatives are typically MP3 files. Some VAST parsers might reject this type of file as it is not a valid format in the strict VAST specification. If you encounter this problem, the best solution is to switch to DAAST, if possible.
If DAAST is not possible, try these alternatives:
- Use a less strict or alternative VAST parser.
- Control the type of files being returned by using the parameters described in the Triton Digital On-Demand Advertising Guide ("Asset Constraints"). For example, you can use MP4 (AAC inside an MP4 Container), as it is a valid VAST media format.
- Make sure your "Mediaplayer" code supports the format being returned (MP3, AAC, FLV, and others).
