Re: [SlimDevices: Plugins] Squeezelite: How to get the sample rate of the stream ???
Ok, done, the code is now working :cool: The last thing to test is if the hardware clock selection is responsive. To be done soon. Thank you all for the help !

Re: [SlimDevices: Plugins] Squeezelite: How to get the sample rate of the stream ???
Thank you Roland, this was it ! So, now I'm trying to compile Squeezelite with the GPIO 4 enabling the right Clock I looked at the code of -gpio.c - and -resample.c- in order to build a new version of resample.o that would integrate GPIO and change it on the fly I first integrated a flag that is 0 when the stream sample rate is 44K1 and 1 when the stream sample rate is 48k, this part of the code is running: 44K1 STREAM -> 44K1 STREAM Code: root@StudioCube:/tmp/squeezelite-master# tac /tmp/squeezelite.log | grep -m 1 "setting Clock from" > [13:40:11.269653] resample_newstream:200 setting Clock from 0 -> 0 =OK 44K1 STREAM -> 48K STREAM Code: root@StudioCube:/tmp/squeezelite-master# tac /tmp/squeezelite.log | grep -m 1 "setting Clock from" > [13:50:55.597058] resample_newstream:200 setting Clock from 0 -> 1 =OK 48K STREAM -> 44K1 STREAM Code: root@StudioCube:/tmp/squeezelite-master# tac /tmp/squeezelite.log | grep -m 1 "setting Clock from" > [13:51:20.552550] resample_newstream:200 setting Clock from 1 -> 0 =OK 44K1 STREAM -> 48K STREAM Code: root@StudioCube:/tmp/squeezelite-master# tac /tmp/squeezelite.log | grep -m 1 "setting Clock from" > [14:01:15.358690] resample_newstream:200 setting Clock from 0 -> 1 =OK 48K STREAM -> 48K STREAM Code: root@StudioCube:/tmp/squeezelite-master# tac /tmp/squeezelite.log | grep -m 1 "setting Clock from" > [14:01:31.542105] resample_newstream:200 setting Clock from 1 -> 1 =OK BUT IF I TRY TO CHANGE THE GPIO, I GET AN ERROR: Although I get no compiling error I have an error when running squeezelite.

Hello Coryls > You could use Squeezelite to resample to a fixed rate (maybe the max for > the DAC) and then there would be no need to switch the DAC's hardware > clock. That's what I'm doing now. Well, I tried two ways. I use a DAC Chip that can be configured with asynchronous recklocking (its default mode), with Squeezelite resampling everystream to the max supported sync rate. However there is still a little to be gained in terms of jitter if I configure the DAC in the synchronous reckloking mode with the Raspberry Pi in Slave mode. I tried it, and that is working fine with a single Clock where I choose to use 176K4 as the bck and do asynch recklocking for every clock that is not a multiple of 44K1. But, as the original stream sample rate is known, a simple toggle swith could activate the right clock (176K4 or 192K). This is very cheap way to get the lowest jitter system clock.

Hello,
I'm trying to go head and add GPIO action directly in the JSON command
Note that i'm not a programmer and didn't know anything about JSON
untill now
So, here is my trial:
Code:
curl -X POST -sd

http://10.144.1.1:9000/jsonrpc.js | jq 'if

echo "4" > /sys/class/gpio/export echo "out" >
/sys/class/gpio/gpio4/direction echo "1" > /sys/class/gpio/gpio4/value else
echo "0" > /sys/class/gpio/gpio4/value end'
> jq: 2 compile errors
> (23) Failed writing body

Any help in the synthax, thank you.

Hello Michael, thank you for helping.
In the mean time I figured that I had to install the JQ command-line
JSON processor to make your script working
Code:
apt-get install -y jq
Then with :
Code:
curl -X POST -sd
'{"id":0,"params":["10.144.1.2",["status",0,1,"tags:T"]],"method":"slim.request"}'
http://10.144.1.1:9000/jsonrpc.js | jq '.result.playlist_loop[0].samplerate'
The system returned :
"48000"
Perfect !

I'm trying to use the Samplerate information in order to switch a DAC
hardware clock on the fly.
For the time being the way I want to test it is this way:
Getting the sample rate each time a new track is starting and from that
select the right hardware clock with a GPIO flag.
However, you are right that it will probably be too late that way.
A solution may be to add a small RAM FiFO buffer before playing on the
hardware.
Something like asking Squeezelite to send the stream to a RAM FiFO and
use the same GPIO flag as before to read the FIFO with sox.
Someone may have another simpler idea.
Any way I go step by step
Step 1 is done
Step 2 is to use "Event Trigger" to execute the above JSON commands
triggered by LMS on each new track
No success yet
Step 3 test Samplerate and change GPIO
Step 4 use the GPIO for the hardware clock selection
Question would it be possible to integrate the samplerate test inside
the Event Trigger config file ?

Re: [SlimDevices: Plugins] Squeezelite: How to get the sample rate of the stream ???
Querying LMS' API will give you the stream's sample rate as received by LMS, which isn't necessarily the same as the one received by squeezelite (unless you make sure LMS never transcodes). I believe bidule needs to give us some more context about what he's trying to do. It sounds as if he needed the sample rate or whatever to _initialize_ the streaming. In which case getting it from the status query would likely be too late. -- Michael ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Thank you Michael, well, you are right I didn't mention the moment, I
wish to get the information just before the playback.
I'll try bpa's suggestion.

Re: [SlimDevices: Plugins] Squeezelite: How to get the sample rate of the stream ???
Lets say I ask for a Deezer track, LMS will stream that track to
Squeezelite as is.
Squeezelite will upsample it.
What I want is to know from a Linux command line is the original stream
sample rate on the fly.
It's not clear to me at what moment you need that information. Before
playback starts? Once it's playing? At any time?
As bpa mentioned you can use the "status" query to get information about
the currently playing track. From a shell:
curl -X POST -sd

Re: [SlimDevices: Plugins] Squeezelite: How to get the sample rate of the stream ???
No need for JSON. >From WebUI Help / technical Information / The Logitech server command line interface Status command shoud giev the info Code: status The "status" query returns the complete status about a given player, including the current playlist. Set the parameter to "-" to get the playlist data starting from the current song. In this "curent" mode and if repeat is on, the server will attempt to return elements, by repeating the playlist at most once, unless shuffling is on and the server is configured to re-shuffle the playlist at each loop (in which case it is impossible to predict the song following the last one in the playlist until this last song has finished playing). Similarly, in the "curent" mode, if repeat is one, only the current song is returned, regardless of the value of . Clients can subscribe to "status" queries, so that the query results are automatically returned asynchronously whenever a change occurs to a player. Please note this mechanism is completely distinct from the "listen" and "subscribe" commands described elsewhere in this document. Accepted tagged parameters: Tag Description tags Determines which tags are returned. Each returned tag is identified by a letter (see command "songinfo" for a list of possible fields and their identifying letter). The default tags value for this query is "gald". In addition to the tags supported by "songinfo" there's the special "DD" tag, which would return no track information, but the total duration of the current playlist only. subscribe This optional parameter controls the subscription to the player status. Only one status subscription is possible per player and connection. Subscription is enabled by using this parameter with a positive integer. It is disabled by using "-". When the subscription is enabled, normal "status" queries (i.e. not using the "subscribe" parameter) can be performed and will have no effect on the subscription in place. When enabled, the "status" request is automatically re-generated on player change (and sent asynchronously to the CLI client). The number indicates the time interval in seconds between automatic generations in case nothing happened to the player in the interval. Use "0" to disable this last feature and only be notified on player or playlist changes. . . . .Example: Simple example Request: "a5:41:d2:cd:cd:05 status 0 2 tags:" Response: "a5:41:d2:cd:cd:05 status 0 2 tags: player_name:127.0.0.1 player_connected:1 power:1 mode:play rate:1 time:13.7129358076728 duration:252.630204081633 mixer%20volume:50 mixer%20treble:50 mixer%20bass:50 mixer%20pitch:100 playlist%20repeat:2 playlist%20shuffle:0 playlist_cur_index:1 playlist_tracks:3 playlist%20index:0 title:Left%20Outside%20Alone playlist%20index:1 title:Bounce%20[Original%20Version]" Current mode example Request: "a5:41:d2:cd:cd:05 status - 2 tags:" Response: "a5:41:d2:cd:cd:05 status - 2 tags: player_name:127.0.0.1 player_connected:1 power:1 mode:play rate:1 time:18.721127818274 duration:252.630204081633 mixer%20volume:50 mixer%20treble:50 mixer%20bass:50 mixer%20pitch:100 playlist%20repeat:2 playlist%20shuffle:0 playlist_cur_index:1 playlist_tracks:3 playlist%20index:1 title:Bounce%20[Original%20Version] playlist%20index:2 title:Open%20Up%20[Radio%20Edit]" Subscribe mode example Request: "a5:41:d2:cd:cd:05 status - 2 subscribe:30" Response: "a5:41:d2:cd:cd:05 status - 2 subscribe:30 player_name:127.0.0.1 ...
