PATCH: changeable default config files
by Richard Smith 25 Aug '05

25 Aug '05

This patch against r70 that adds the ability to override the names of the default system and user config files. For example dancebox is started with ./dancebox.py rather than ./pytone.py and the config files are /etc/dancebox.conf and ~/.dancebox/* This is a small step toward my seperate UI modules patch. It also adds an error message if pytone can't find any of the config files where previously it just told you that you needed at least one basedir statement in the config file. Joerg: When I did an svn update I had conflicts with every part of my playspeed mods. But looking at them in (most) cases I couldn't really see any difference. Was there some sort of space or tab issue or something with my patch? -- Richard A. Smith

pytone and flac support
by Dag Wieers 24 Aug '05

24 Aug '05

Hi, I tried today pytone 2.3.0-pre1 and python-flac support and it works as expected, the only thing that seems to be missing is a working progress-bar. It stays at "0:00/ 6:10" during the whole song. Forwarding en reversing through the song worked, as well as speeding it up or slowing it down :) I was surprised that the crossover was working too. Don't know if you had much feedback about flac support, but if the progress bar is fixed, the experimental flag, for my part, could be dropped. (for the limited set of flac files I have) PS SHN is next now :) If only there were python-bindings... Kind regards, -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power]

ANN: PyTone 2.3.0-pre1 released
by Joerg Lehmann 24 Aug '05

24 Aug '05

Hi PyToners! I just uploaded a pre-release for the next major PyTone version. It can be found under http://www.luga.de/pytone/download/PyTone-2.3.0-pre1.tar.gz Please test extensively as there are many, partially rather invasive, changes included in this release. In particular, a new database version requires an update. You, thus, should backup your song databases before running the new release for the first time and ensure that there is enough disk space for the upgrade. Included is a C version of the output buffer which needs the header files of the libao library for building. A detailed list of changes is attached. Enjoy, Jörg 2005-08-23 Jörg Lehmann <joerg(a)luga.de> * Add error reporting to bufferedao extension module. 2005-08-22 Jörg Lehmann <joerg(a)luga.de> * Disabled automatic closing of help window by default. * Added changeable play speed support (many thanks to Richard A. Smith <smithbone at gmail dot com> for providing the patch). 2005-08-21 Jörg Lehmann <joerg(a)luga.de> * Merged item-rework branch, which contains a new filter code. The new code makes the unfiltered case a special case of the filtered one. As a result, more than one filter can be applied, e.g., filtering for all songs in a certain genre of a given decade and with a given rating is now possible. Furthermore, every index now contains a (nearly) full directory hierarchy, thus allowing things like showing the top-played songs of a certain genre. 2005-08-19 Jörg Lehmann <joerg(a)luga.de> * Get rid of multi-file database layout: - convert old layout automatically - leave configuration file switches basename and dbfile intact but warn the user when they are non-empty - in a next step, we will set the default value of the basename switch to an empty value (when presumably all databases have been converted) - finally as a final step, we remove the switches and require that the users change their config files * Database version 5: do not longer index by years but by decades which removes many special code paths at various places in the db code. 2005-08-11 Jörg Lehmann <joerg(a)luga.de> * bufferedao.c: New C extension module corresponding to services/players/interal/buffereddevice with an ao device. The advantage of the C module is that it does not have to rely on holding the GIL when doing the output, which should help preventing sound dropouts. * services/players/internal.py: Make use of new extension module bufferedao. 2005-08-10 Jörg Lehmann <joerg(a)luga.de> * services/songdbs/internal.py: Checkpoint database regularly during registering of songs to prevent oversized transaction logs. * services/songdbs/internal.py: Replace quadratic in number of songs algorithm by a linear in time version to avoid huge system loads at the end of the song registering process. * services/players/internal.py: Do not open audiodevice without need. 2005-08-09 Jörg Lehmann <joerg(a)luga.de> * help.py, helpwin.py, statusbar.py: Introduced getkeyname function which has a fallback solution for unnamed keys (thanks to Troels Vognsen <bashfalcon at gmail dot com> for reporting this problem). 2005-08-03 Jörg Lehmann <joerg(a)luga.de> * Normalize all paths in config files. * Rework dbstats system. 2005-08-02 Jörg Lehmann <joerg(a)luga.de> * services/songdb.py. Measure cache size not by number of stored requests but by the number of objects the requests refer to. * services/songdb.py: rename resultcache -> requestcache. * conf/pytonerc, config.py, services/songdb.py: Add new section database with currently only one option requestcachesize, which allows one to configure the maximal number of objects contained in the cache. * item.py: Create genres/ratings/etc. instances only once to permit the caching of the requests involving them. * statswin.py, config.py, conf/pytonerc: New window for statistical information about databases and the request cache (accessible via "%"). * Various updates in German PyTone.po. 2005-07-16 Jörg Lehmann <joerg(a)luga.de> * plugin.py: Use thread-local channel in threadedplugin to make it actually a threaded plugin. * log.py: Add time and current thread to debugging output and prune common path from module name. 2005-07-16 Jörg Lehmann <joerg(a)luga.de> * filelist.py. Update window contents in filelistjumptosong(). * plugin.py. Daemonize threaded plugins, in order to prevent a blocking of misbehaved plugins on shutdown. * Initial checkin into Subversion repository. 2005-06-30 Jörg Lehmann <joerg(a)luga.de> * plugin.py: Use init() method instead of start(), which has a different meaning for threads. The plugins currently distributed with PyTone have been changed in this regard. * plugins/audioscrobbler/scrobbler.py: Fix typos in backlog code. 2005-06-28 Jörg Lehmann <joerg(a)luga.de> * config.py: Be more liberal concerning the accepted section names (patch by Dag Wieers <dag at wieers dot com>).

pytone locks
by Horst Eyermann 23 Aug '05

23 Aug '05

Hello, I noticed before that PyTone locks sometimes when stopped and started again. - Everything starts, but the song does not start to play. At the moment the only solution I have is to shut-down the system and start it again which is anything but convenient. Has anyone else experienced this? How can I avoid the lock ups or find out what is causing them? Thanks, Horst

Extended search function
by Stefan Wimmer 23 Aug '05

23 Aug '05

Hi all, as I start to use PyTone more and more for my DJing I wanted to put your attention to an underestimated function which is not yet discussed a lot here although I think it could be optimized (if time permits it of course) a little bit more: the *search*-function ... I would *love* to have those features in the search-function: - the ability to use it everywhere and not only inside the songs-window Isn't it possible to use the database for any search-operation as it is already in the memory as I suppose? - a separate window with all the results of the search-operation that I can use for prelistening and queueing as needed - an history of the searches I processed at least for the current PyTone-session Again this is only a question to look at the possibilities as I am only a user and not a programmer and therefore not able to transform my whishes in some useable software ;-) Joerg, are you willing to have a look at this? Do you think it is possible at all? Or is it simply to much work to implement something like that? I hope I am not too rude to ask for this but hey I love this program and I think it would just make it even more valuable!! ;-) Greetz Stefan ========================================================= My very personal wishlist for Pytone - just ignore it ;-) ========================================================= * BPS recognition Show the bits per seconds from a song in the MP3 info window * Indicate time when playlist will stop Show not only the entire time a playlist will last but as well the daytime it will end :) * Modifiable playlists Modify/delete playlists * Pause between tracks * Some sort of replaygain * Extended search function -- Stefan Wimmer <swimmer(a)xs4all.nl>

Add play speed controls
by Richard Smith 22 Aug '05

22 Aug '05

The following patch adds play speed controls to pytone. Diffed from svn but should apply and work for any recient version of PyTone. 'f' plays faster 's' plays slower 'd' resets to the original speed. Each key press should adjust the speed ~1%. These of course change the pitch as well. -- Richard A. Smith

pytone on OSX?
by Robert Ames 19 Aug '05

19 Aug '05

Hi- Has anyone had luck using PyTone on OSX? I've use PyTone in the past on my linux box (thanks, works great!), but ever since OGG support broke with iTunes in latest Mac updates, I have a serious interest in getting PyTone working (as I also have ~4000 songs and few other music players handle it well). Anyway, I've done the following on the mac side (everything is working great on recent Ubuntu install on a different computer so I know it works with my collection, setups, etc): 1- Download pytone (2.2.4) 2- do the: "python setup.py build_ext -i" thing 3- "Fix" _bsddb problem on OSX (http://pythonmac.org/packages/ and put _bsddb.o into ..../python2.3/lib/) 4- update ~/.pytone/pytonerc to point to my music 5- Start PyTone, and no songs get loaded ...here's log snip: I 08:25:40 Using configuration from file(s) /private/etc/pytonerc, /Users/rames/.pytone/pytonerc W 08:25:40 disabling mixer since neither ossaudiodev nor oss module is installed I 08:25:40 PyTone 2.2.4 startup I 08:25:40 Ogg Vorbis support disabled, since module is not present I 08:25:40 using integrated MP3Info module for id3 tag parsing I 08:25:40 flac support disabled, since flac module is not present I 08:25:41 database main: basedir /Users/rames/muzak, 0 songs, 0 artists, 0 albums, 0 genres, 0 playlists W 08:25:41 transparency support disabled because cursext module is not present W 08:25:41 terminal does not support disabling of cursor I 08:25:43 database main: scanning for songs in /Users/rames/muzak I 08:25:43 database main: finished scanning for songs in /Users/rames/muzak ...which looks like it has the following problems: 1- No sound file support on OSX 2- No ogg support, since it's not finding any of my OGG's Is this correct, or am I missing something? Thanks again... --Robert

Speaking of LAD
by Richard Smith 11 Aug '05

11 Aug '05

Looking at the LAD page got me thinking that PyTone probally need to look at supporting JACK. JACK was designed by the LAD folk for low-latency no dropout audio and they have tons of experience gettting it to happen. Does PyTone have any plans to try and set any of the realtime process flags for the decoder thread? Most of these would require you to suid root for pytone but it may go a long way to solving your drop out problems. I'm thinking that the dropouts may be caused by the garbage collector in python. #1 non-deterministic problem in embedded and realtime systems is memory management. Most of the time it falls into the "Don't do that" catagory when running realtime stuff. Considering the ammount of RAM you guys are reporting PyTone using the GC may take a good bit of time to figure out what it needs to do. I've not played with the GC tweaking stuff in python but I seem to remember that there is more than one algo you can select for GC. Perhaps a less intrusive GC + realtime priority on the decoder thread might help? -- Richard A. Smith

Introduction
by Doug Friend 11 Aug '05

11 Aug '05

Hi, Thought I'd introduce myself. Just installed PyTone 2.2.4 & have it running after a couple of tries. On initial set up I pointed it to 120GB of music which caused some fairly severe performance issues. Anyone have experience with PyTone & a large music collection? I'm new to Python, have been coding with Perl for the last 5 years or so. I have been planning to write a playlist generator which will take additional parameters than what is currently in PyTone (tempo, texture, music style among others). Just starting to get into the code now, so any words of wisdom would of course be more than welcome :) Thanks, Doug.
