Analysis
========



DTS is abbreviation from Decode Timestamp. Muxer (multiplexer) combines multiple data streams into single stream eg. for transfer.

From https://stackoverflow.com/a/76222700: The 'non monotonically increasing dts' issue is mainly a result of streaming the input video file in a loop. Each time the loop starts, the timestamps starts from the beginning. The remuxing procedure copies the timestamps from the input to the output, so there is a 'non-increased DTS scenario' each time the loop restarts.

Is it a bug in the validating software? - no

Convert file format with ffmpeg
===============================

Suggestion
~~~~~~~~~~

The problematic WMA file is converted to WAVE format using FFMpeg.

Effects
~~~~~~~

The file format changes to the WAVE format.

Justification
~~~~~~~~~~~~~



Execution example
~~~~~~~~~~~~~~~~~

	ffmpeg -i <problematic WMA file> <converted WAV file>
