Asset MediaPackage has no audio especification

Hello Alisson,

Based on your note, I understand the HLS file from MediaConvert plays well but for the MediaPackage asset, the audio is silent. Here are some checks you can perform on the no audio file :

1. ffprobe on the mediaconvert output
2. ffprobe on the MediaPackage output

For the MediaConvert output, since it is working as expected, you should be able to see an audio stream on the ffprobe output like this: Stream #0:10x101: Audio: aac (LC) ([15][0][0][0] / 0x000F) .....

For the MediaPackage output, the audio stream should be missing from the ffprobe output since the output playback is silent.

I would suggest you to make a minor adjustment to the MediaConvert job settings: We recommend setting "Minimum final segment length (sec)" to 1 second, and re-running the conversion job. This will ensure MediaConvert does not produce a really short (<1s) length final segment.

When a Minimum final segment length is not set, MediaConvert could produce a segment that is less than 1 second long. Such segments usually contain only a few frames, sometimes only video and no audio frames.

The "Minimum final segment length (sec)" config can be found under Output Groups > Apple HLS. Once you have re-converted the file with this change, please try ingesting the new asset into MediaPackage, and give it a test.

If this still does not fix the silent MediaPackage output issue, I would recommend you to create a Support case with the AWS MediaPackage Support team for assistance.
