Playback error with FLAC inside MP4

[elan]

Sample: https://files.plexapp.com/elan/sample.m4a

Architecture: aarch64
BASS: Core version 2.4.18.3
AAC plug-in version 2.4.7.1

I swear there was a fix for this sort of file a while back and was seeing the error on 2.4.17.0, but after an upgrade, still seeing it.

Getting BASS_ERROR_FILEFORM when opening.

Thanks as always!

What platform are you running on? I believe FLAC-in-MP4 is currently only supported on Windows and Android, with the help of the OS's decoders (eg. Media Foundation on Windows). The BASS_AAC add-on unfortunately won't help because that only supports AAC data (not FLAC).

Ah, apologies for not mentioning the most important thing, the platform!

It's Linux, so I guess the issue is expected. A bit of a pity as there seems to be a fair bit of this weird combination floating around these days. It does work on macOS and iOS, likely due to using the system demux/decode there too.

There are some plans for an MP4 demuxing add-on, similar to BASSWEBM. I can't say when that may be available at this stage, but hopefully it'll mean these files become playable on Linux at some point.
