squeezelite can't play some m4a files

[m-reiter]

I'm experiencing a problem with some m4a files in squeezelite on Linux (ARM and x86): Playback of these files fails with the following output on decode=debug:

Here's the mediainfo output for one of the files in question:

Linux distributions are Raspbian stretch on ARM and Debian stretch on x86. On the latter, I have tried a self-compiled version of squeezelite with identical results to the packaged version.

The faad binary linked against the same libfaad is able to decode the file without issues.

I can provide one of the affected files on request.

Thanks very much in advance for any help!

Update: Solution was pointed out to me in the Slimdevices Forum here: Seems like the files in question have some audio index at the end of the file and are therefore not suitable for streaming.

I'll leave this open for a couple of days in case anybody wants to comment. Issue is solved though.
