Failure while processing: audio_object_type_ < 31 with xHE-AAC audio

[christosts]

Hi team,

I'm trying to create a DASH package from an xHE-AAC audio file. When parsing the file, I get the error

[0729/132723:ERROR:aac_audio_specific_config.cc(68)] Failure while processing: audio_object_type_ < 31
[0729/132723:ERROR:box_definitions.cc(1691)] Failure while processing: aac_audio_specific_config.Parse( es_descriptor.decoder_config_descriptor() .decoder_specific_info_descriptor() .data())

I guess the failing assertion is here but I can't tell if the issue is that the specific format is not supported in general or something else in the bitstream of this file.

System info

Operating System: Linux Debian 5.17
Shaka Packager Version: 2.6.1

Issue and steps to reproduce the problem

xHE-AAC audio file cannot be parsed

Packager Command:
./packager-linux-x64 in={audio.mp4} --dump_stream_info

What is the expected result?
The packager parses the audio file and prints the stream info

What happens instead?
Output copied in details below

If the format is generally supported and the issue seems to be related to the specific file, I can share the file to [email protected].

Thanks

I am having the same issue, with multiple files.
