TAP feature not working properly

[ks61625]

I've just experimenting with TAPs...and experiencing some strange behaviour...one of those is, when TAP starts encoding into its corresponding *.taf.tmp file, the box blinks red and shutdown emidently. It seems that the content of *taf.tmp is not sent to the box while encoding? Since the conversion will abort when I just restart the box and try to play the TAP again, I just let the box shutdown (waiting for finishing conversion). Which is fine for short content. But When it is a longer content, the converions aborts either, caused by time out...since nobdy is consuming the stream? So it seems that I cant consume the stream befor its conversion is done, but I cant complete the conversion due to not consuming it.

This is the corresponding docker log when aborting conversion by time out while box was / is shutted down:

Another user in telegram had similar if not same experience:

Hello, I have tried to combine several TAFs via a TAP (playlist). As soon as I assign this TAP to a TAG, a *.taf.tmp is created when the TAG is set up. I can play this via the browser. However, the Toniebox flashes red several times and then switches off.

Is there anything I can do / adjust to make conversion not abort / timed out ?

If there is anything I can provide you with, just tell me.

Edit:
Toniebox is cc3200
TeddyCloud version is 0.6.2 (203f12d) ubuntu linux aarch64
docker host is raspi5-8gb

Please provide an example TAP

[ks61625]

This is my TAP content:

{
	"type": "tap",
	"audio_id": 0,
	"filepath": "lib://by/tapID/Deep Focus Mix.taf",
	"name": "Deep Focus Mix",
	"files": [
		{
			"filepath": "lib://by/mp3/Deep Focus Mix.mp3",
			"name": "Deep Focus Mix"
		}
	]
}

The mp3 has 82MB size and a playtime of 1h 29m 34sec
VLC Codec info is:

Codec: MPEG AAC Audio (mp4a)
Stereo
44100Hz
Bits per Sample: 32

When placing the tag on the box, no error-sound occurs, just blinking red LED ... then the box switches off (after ~15sec).

I can confirm exactly the same behaviour. Tried it with different input files, mp3 and m4a (aac).

Toniebox: CC3235
Teddycloud: develop (vX.X.X 9930675)
OS: Raspberry Pi OS (bookworm)

The strange thing is that Teddycloud itself seems to work without problems. It transcodes the src file, first to *.taf.tmp and then renames it to taf when ready. So when I turn on the Toniebox again and put the same tag on it again, it starts playing without a problem (incl. downloading of the converted taf). But I have to wait until the transcoding is finished (by checking the logs). If I turn the box on again too quickly, the tmp file will be deleted and it starts from the beginning (incl. turning off/crashing)

Sometimes there is an error at the end saying file /teddycloud/data/library/by/tapID/Modjo.taf.tmp not available or not send, error=End of file reached [304].... I guess this happens with small files where the transcoding finishes quite fast. But I also tried it with longer files. Only one file. Nothing special.

  ]

As long as the converting TAF.tmp file is not bigger than 25 MB. In my case (1,5h audio) the TAF encoding aborts on ~25 MB. Encoding same mp3 (from above) with teddycloud-cli all went well. Target TAF size is ~80 MB.
