I've just released a first version of a new bridge that allows airplay
devices to be used as is they were regular LMS players. Compared to my
other bridges, it brings replaygain, gapless, fading (in/out/cross) and
... what was the most important for me: synchronization with other LMS
players.
Please be aware of the following at this point
- it is experimental, so expect (a lot of) issues
- it consumes a bit too much CPU (3~10% on my raspi 2B) - I have a
lots of optimisations in mind
- being an airplay system, it uses 1.4Mbits/s of network bandwidth per
active player (44.1*16*2)
- IT ONLY SUPPORTS PCM AND AIFF, ALL OTHER FORMATS MUST BE TRANSCODED
BY LMS (you need to edit your custom-convert.conf, see below)
- IT ONLY SUPPORTS 44.1 kHz, ALL OTHER SAMPLE RATE MUST BE RESAMPLED
BY LMS
- THERE ARE ONLY WINDOWS, LINUX (x86 and x86_64 and armv6hf) - I WON'T
DO ANOTHER VERSION SOON
- my test environment is Windows, so Linux versions are much less
tested
- it can run on LMS or another computer
Only use this if you are want to do some test and tinkering. If you
don't know how to edit your custom-convert file, please wait till it's
more mature. If it works well, I will add support for more codecs (mp3,
flac at least) as well as re-sampling, but currently my objective is
stability of the main features. The link to the repo is here
http://sourceforge.net/projects/lms-to-raop/files/dev/repo-sf.xml.
Once you have started the plugin, allow 15-60s for players to appear.
For synchronisation, you need to adjust once your player delay in the
LMS player settings (not in the plugin setting page). Once you have
found the right delay, it should be pretty stable (I never had to adjust
mine on my 2 players, they are 375ms) - I've added a quick manual ...
have a look at it
To transcode mp3 to pcm, add the following to custom-convert.xml (needs
lame as well) (you could/should replace "*" by the mac address of the
player to avoid systematic transcoding for all squeezelite players -
this mac address can be found in the plugin setting page)
Code:
--------------------
mp3 pcm squeezelite *
# FT
[lame] --mp3input --decode -t --silent $FILE$ -
--------------------
other notes :
- the log file can grow very quickly when something wrong happen, be
careful, you can erase/disable it in the plugin settings
- if the player seems to be un-responsive, before
de-activating/re-activating the plugin, you can try to switch it off/on
in LMS
- one of my player takes a lot of time to start playing (>5s and volume
changes interrupt playback - itunes gives the same result, so I assume
this is a player problem, so I've added this digital volume option to
avoid using the player's volume command, but it adds to CPU consumption
as every sample must be scaled up/down)
