With time I've learned I think pretty well the behaviour of the .conf files, but I must say that the header lacks a bit of clarity when it says Code: # Capabilities # I - can transcode from stdin etc. etc. The subject of the sentence is missing, and for newcomers the meaning could be puzzling. Something like "The first executable binary of each entry can transcode from stdin" would make all those statements clearer, IMO. Perhaps one of the code maintainers could add this in one of the future releases? That would be much appreciated (at least by me!). scala's Profile: http://forums.slimdevices.com/member.php?userid=13391 View this thread: http://forums.slimdevices.com/showthread.php?t=111718 ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter

It does not have a specific "model", which is the 3rd field of the convert.conf, but you can always do specific rules by its MAC address.

I dont see what more you'd want To convert all formats, you need a rule for each format. You can simplify your life by only allowing one codec for the upnp players, e.g. flac and only have the rules to transcode *to* that format You can't be specific to all upnp devices as they don't have their own model, just a modelName which is not used as a criteria for rules, but you can use their MAC addresses LMS 8.2 on Odroid-C4 - *SqueezeAMP!*, 5xRadio, 5xBoom, 2xDuet, 1xTouch, 1xSB3.

Hi, I have the same setup LMS - UPNP Bridge - KEF LS50 W. And I also doing DSP with Sox and Qobuz Streams. What setting are you using with the UPNPBridge and the KEFs? I have mostly in the beginning of the tracks one little hiss. Have you noticed something similar?

PLAY AROUND USING LOGGING OF PLAYER.SOURCE SET TO INFO AND SEE WHAT THE CREATED COMMAND LOOKS LIKE - TRY DIFFERENT CONF SETTINGS. MUST RESTART FOR CONF FILE CHANGES TO TAKE EFFECT. Look at the real example in convert.conf and understand them fully. # F means input comes from a file (i.e. LMS will subsituted $FILE$ for the file name - the #F" tells LMS the created command line after substitution will contain a local file name) # I means input comes from stdin to the trancoder command (stdin from LMS processing source as a byte stream i.e. LMS will substitute "-" for $FILE$ in the command line and also provide the data) # R means input comes from remote (i.e. LMS will substitute $URL$ possibly $FILE$ for the remote URL) So the capabilities tell LMS, the command created after subsitution will be valid & work (i.e. a viable transcoding). The options tell LMS what to substitute to build the appropriate command. For example, faad can process input file or stdin but not remote URL so anyt faad command cannot have a "R" so faad can be used to play MP4 files but not The #T means a byte offset so the command created after substitution will be able to skip to start time/byte. This usually means one of the follow have to be in the command line. Code: # %o - stream start byte offset # # %S - stream samples start offset (not yet implemented) # %s - stream seconds start offset # %t - stream time (m:ss) start offset # %U - stream samples end offset (not yet implemented) # %u - stream seconds end offset # %v - stream time (m:ss) end offset # %w - stream seconds duration bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=111718 ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter

At the start of the convert.conf file - all settings/formats are detailed.

[SlimDevices: SqueezeCenter] DSP of Quboz Streams via SOX + UPNP Bridge (for KEF LS50W)
Hello colleagues,
I am currently trying to set up a room correction via DSP in the LMS
server via SOX and need some help.
Setup:
- Source: FLAC Streams from Quboz or Tidel (16bit / 44.1 KHz - 24bit /
192Khz)
- Logitech Media Server version: 7.9.2
- UPNP DLNA Bridge
- KEF LS50 Wireless (active speakers with UPNP renderer)
UPNP DLNA Bridge setup for LS50W without transcoding.
I have tried to write a custom-convert.conf for the equalizing of the
streams for the LS50W with this code (MAC-ID is only sample):
Code:
flc flc * 00:00:00:00:00:00
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t flac -C 0 -b
24 - gain -1 rate -v -I -b 98 88200 equalizer 200 0.33q -10
But this doesnÂt work.
First of all, I recognized, that it is not possible to do special rules
in the custom-converter.conf for devices communicating via UPNP DLNA
Bridge.
This seems to be caused by the architecture of this plugin.
Maybe someone has experience how to set up transcoding rules for UPNP
devices.
The documentation of the convert.conf is really bad - so I had done some
trial and error with help of Google.
So this is the current state:
Code:
flc flc * *
# IR
[flac] -cs - - | [sox] -q -t flac - -t flac - equalizer 312 1.237q -5.8
equalizer 201 2q 6 equalizer 229 5q -9.9
I can only define rule for all devices which with effect for UPNP
devices and must then setup rules for all the other boxes in my
network.
*So it works! - DPS for Quboz and Tidal streams up to 24/192 - great
stuff!*:cool:
But there are some questions - maybe someone can answer a few of them:
- Is there a better documentation for the convert.conf?
- What does "# IR" stand for?
- How to convert all formats (e.g. mp3) in that way, that the LS50
Wireless receives this equalized flac stream?
- Is there a way to define rules for UPNP devices in the convert.conf?
- Is there any improvement in the SOX command I use?
