(It seems to me that I still have some audio frames lost

but I do not know if it is due to the signal i have to test this longer)

Did you install latest files?

Because the latest files should print {"mot":"/tmp/xxxx","mot_type":"y"}

There is no "mot" printed in the log? Are you using latest dab-cmdline?

You are still using wrong plugin.py.
 
			if "mot" in rds:
				self.showPicture(rds["mot"].encode('utf8')[:-2]) 
The mot contains the path to image without the mot_type, the mot_type is now different field in json. So removing the last two chars from mot is not required.

There is not enough cpu power on mipsel to perform viterbi decoding.

Please feel free to provide an mipsel optimized viterbi algorithm.

Until then, just forget mipsel.

 

 

Working on SF4008,  I have to try sometimes several times to lock signals, but finally I got it working.

PCM mode works for DAB and DAB+

non-PCM works only in DAB+.


Enigma is getting old....

Can you create a small I/Q file (up to 60 seconds) with DAB? In order to check why DAB + faad is not working?

(use dab_raw_record.sh from here: https://gist.githubu...b_raw_record.sh)

Which multiplex do you want ?    DAB only multiplex, or DAB/DAB+ multiplex ?
