svn-1082 on NSLU2

[fizze]

Hey ron, cheers for giving us transcoding thru rsp. 🙂

Am i right that in

Make unix-slashes .m3u files work on win32 and vice versa

I should be able to use native relative-pathed winamp .m3u’s on the slug’s music repository ? 😉

[quote=”fizze” I should be able to use native relative-pathed winamp .m3u’s on the slug’s music repository ? ;)[/quote]

That’s the theory, yeah. Does it work?

[fizze]

havent yet upgraded. but I will do so shortly 🙂

edit:
I set process_m3u =1 and the server did come up, but it refuses to show any content.
My soundbridge reboots gracefully and tries to reconnect then, which is kinda bad to.
iTunes clients get no data as well, but dont show any error.
I dont know whats wrong.
The webinterface seems to work though, although it shows any DB related functions return nothing.

I gotta dig into this to find out whats happening.

Could it be that some bogus m3u lists cause it to fail like that ?

I hope I find the time to investigate this in the next few days. Im kinda busy now.

edit2:
well, just as I thought, if I comment out the process_m3u setting it just comes up, but it doesnt stream any content. I could see the database contents in the web interface’s “playlist” view.

edit3:
ok, I tried to play with some other other config settings, and also with -d9.
no info. now even the webinterface refuses to come up.
There are 3 mt-daapd instances with state “S” and one with state “D”. that one can only be killed by -9’ing it.

any clues ?

kill -9 everything and make sure it’s dead. Start it in the foreground with a -d9 and see what you see there. (/opt/sbin/mt-daapd -c /opt/etc/mt-daapd/mt-daapd.conf -f -d9 -y)

[fizze]

I killed my DB files (there were like 4 with very temp-ish sounding names), and rerun it with -d9 last night.
Today its running fine. Weirdest thing.

BTW is there a way to save one’s smart playlists ?
like a small DB export/import ?

edit:
it ran fine with transcoding deactivated, and no process_m3u.

Now Im running in foreground with -d9 and stuff, without process_m3u, but with transcoding at least.

As far as I can tell its working, but its slow as hell.
Browsing from my Notebook via iTunes took like 10-30 seconds to get the full list, I am now waiting for 5+ mins, and its still not here.
In putty I can see mt-daapd is happily at work though.
Seems those selects just take forever … ?

edit2:
a snip of the log file:

[fizze]

On a sidenote, when the server is in this state, it makes a soundbridge reboot upon connection failed, and then disconnect.
here’s the log from mt-daapd, while this happens:

# This is the location of a playlist file.
# This is for Apple-style “Smart Playlists”

#
# These are the file extensions that the daap server will
# try to index and serve. By default, it only indexes and
# serves .mp3 files. It can also server .m4a and .m4p files,
# and just about any other files, really. Unfortunately, while
# it can *attempt* to serve other files (.ogg?), iTunes won’t
# play them. Perhaps this would be useful on Linux with

# Program that is used in server side format conversion.
# Program must accept following command line syntax:
# ssc_prog filename offset
# Parameter filename is the real name of the file that is
# to be converted and streamed, offset is number of bytes
# that are skipped from the beginning of the _output_ file
# before streaming is started. The resulting wav file (or
# rest of the file after initial seek) is written to the
# standard output by the ssc_prog program. This is typically
# a script that is a front end for different conversion tools
# handling different formats.

#
# Not that the -d switch will control the log verbosity.
# By default, it runs at log level 1. Log level 9 will churn

# like zina or andromeda, for example, with cover art called
# “_folderOpenImage.jpg”, you could use the parameter
# art_file _folderOpenImage.jpg and if the file _folderOpenImage.jpg
# was located in the same folder as the .mp3 file, it would appear
# in iTunes. Cool, eh?

#
# rescan_interval
#
# How often to check the file system to see if any mp3 files

#
# if not specified, the default is 0, which disables background scanning.

#
# The default behavior is not not do background rescans of the
# filesystem unless there are clients connected. The thought is to
# allow the drives to spin down unless they are in use. This might be

# 24×7. Forcing a scan through the web interface will always work
# though, even if no users are connected.

# process_m3u

#
# If you are sure your m3u files have good paths (i.e. unixly pathed,
# with relative paths relative to the directory the m3u is in), then

# This sets how aggressively mp3 files should be scanned to determine
# file length. There are three values:
#
# 0 (Normal)
# Just scan the first mp3 frame to try and calculate size. This will
# be accurate for most files, but VBR files without an Xing tag will
# probably have wildly inaccurate file times. This is the default.
#
# 1 (Aggressive)
# This checks the bitrates of 10 frames in the middle of the song.
# This will still be inaccurate for VBR files without an Xing tag,
# but they probably won’t be quite as inaccurate as 0. This takes
# more time, obviously, although the time hit will only happen the
# first time you scan a particular file.
#
# 2 (Painfully aggressive)
# This walks through the entire song, counting the number of frames.
# This should result in accurate song times, but will take the most
# time. Again, this will only have to be incurred the first time
# the file is indexed.

I hope there’s some clues about that.

[rpedde]

can you make it fail on demand?

[fizze]

the soundbridge ?
yes. its reproducable.
With the above recipe, on my slug.

like I said, it works with iTunes, but its so darn slow that noone would expect its working.

Do the above log files look even “normal” ?

[rpedde]

Yeah.

It really sounds like one of several things. It sounds like you have multiple mt-daapds running (the multiple temp files in the db dir) and it’s slow because of db contention.

Or, you are cpu pegged on something else (or maybe on a transcode), adn that’s slowing you down. Transcoding will do that if you aren’t using the ivorbis-tools package, or if you are using a home-build alac decoder… not the alac-decoder package in unslung.
