I'm trying to diagnose the same problem. I'm using "Ralphy's ffmpeg
version". Trying to play a track, squeezelite tells me:
Code:
--------------------

[22:05:12.375828] faad_decode:388 error reading stream header
--------------------
ffmpeg has this to say about codecs in the file:
Code:
--------------------
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'funk.m4a':
Metadata:
major_brand : isom
minor_version : 512
compatible_brands: isomiso2mp41
encoder : Lavf56.4.101
Duration: 00:04:30.44, start: 0.000000, bitrate: 254 kb/s
Stream #0:0(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo,
fltp, 253 kb/s (default)
Metadata:
handler_name : SoundHandler
--------------------
The same track plays just fine on my Squeebox Boom. Looking at my LMS
server, it looks like the file is getting transcoded before being sent
to the boom, because I see a "faad ... | flac ..." pipeline running. I
don't see the transcoding pipeline start up when squeezelite tries to
play the same track. I'm guessing this has something to do with the
codecs that squeezelite is reporting to LMS.
I'd be happy to either (a) get squeezelite to just play the track as is,
or (b) figure out what codec setting is necessary to make things work
like they do for the Boom.
