AVI Viewer’s General Info
All container errors, such as important AVI chunks absence, incorrect container structure or invalid header values, pointed as mandatory in the corresponding specification are output as Error Report. All container irregularities, which are not pointed as mandatory in the corresponding specification, but have unusual content are output as Warning Reports. Additionally there is a set of Informational Reports, which deliver more detailed information about the file being examined, such as the stream format, media duration, etc.
Each AVI container check can be disabled or enabled or set to another report type, such as Info, Warning or Error. The solution can be applied in wide variety of workflows and with many container format deviations due to its flexibility and customization ability.
The validation report output can be exported into XML report file, containing 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.
The validation takes only a few seconds for an average long and complex media file to be processed.
