AAC video not playing and "Unknown encoder '' " error

[murphy2712]

I'm trying to read video files with AAC 6 channels to a Chromecast.

Video Station doesn't seem to like AAC files (with more than 2 channels) so I installed this wrapper to try. Now when playing a video with AAC (6 channels) it doesn't play and stays at 00:00.

I'm using a DS923+ with the latest Video Station, AME, ffmpeg 6 and the advanced wrapper. I noticed that AME shows only HEVC but not AAC:

Here are the logs I found:

I don't quite understand the config, maybe there's a setting to fix this? Or I should transcode before playing? ( I tried without success)

Thanks for the help!

Please use a MKV not a MP4. The AVC1 (video's codec) is not fully compatible with your NAS.

Have you got others wrappers installed in your system?

I just tested and is working fine:

Regards.

[darknebular]

if you're getting that error, that's because you used my Wrapper but it looks like you didn't use my installer or you have an error produced by another wrapper's installer...

Could you to ensure that the entire system is clean, uninstall AME and VIDEOSTATION and reinstall everything, this time using my installer on the clean system?

Regards.

So it seems the avc1 codec is the issue, not the aac audio? I have no other wrapper, I already reinstalled a couple of times but I will retry. Uninstall the wrapper, AME, Video Station, then reinstall...

[darknebular]

So it seems the avc1 codec is the issue, not the aac audio?

Probably YES!!

Best regards.

I reinstalled but have the same Unknown encoder issue. I can play the movies on the web videostation on my computer, but cannot cast those on Chromecast.

I have the same issue on hevc videos, but still having 5.1 aac audio:

Also from a h264 file/aac 5.1. Maybe my uninstall/reinstall is not working? I'm uninstalling the wrapper, AME, Videostation, then install videostation, AME, the wrapper advanced. Is this the way to reinstall? I didn't reinstall ffmpeg (keeping v6).

Am I missing something?

I will replay to you, asap. Thanks for the Anydesk Code, I could to fix It.

[murphy2712]

Strings to add in ffmpeg41 l.400, l.428 and l.453: " || grep "Unknown encoder" /tmp/ffmpeg-${streamid}.stderr "

[darknebular]

Yes, I remember the changes and the lines. Thanks for your time, finally was due to your DSM Version and not to AAC 5.1.

I Will do This change in the Next minor release.

[darknebular]

I am glad that finally works fine for you.

BEST regards.

[darknebular]

Don't forget the star jejeje 😝

[murphy2712]

Thank you for the assistance! I'm also glad we fixed my casting issue and found a patch for the wrapper.
