1 | So, you want to develop gutenbach, eh? Good! |
---|
2 | |
---|
3 | Gutenbach is a distributed music player built on top of CUPs. It |
---|
4 | essentially enables anybody with access to it to play music from their |
---|
5 | own computer -- all they have to do is "print" to the Gutenbach |
---|
6 | instance as they would any other document! |
---|
7 | |
---|
8 | The current Gutenbach features are: |
---|
9 | - the Gutenbach server (packaged as gutenbach-server) |
---|
10 | - a terminal queue display (packaged as gutenbach-queue) |
---|
11 | - remctl bindings (packaged as gutenbach-remctl) |
---|
12 | - client-side scripts to print to, list, and delete from |
---|
13 | queues (packaged as gutenbach-client) |
---|
14 | - a Rhythmbox plugin |
---|
15 | - iTunes plugins |
---|
16 | - a webapp interface |
---|
17 | |
---|
18 | All of these are located on GitHub: |
---|

---|
20 | |
---|
21 | Additionally, see README.old for how Gutenbach /used/ to be installed. |
---|
22 | This can sometimes offer insight into how to fix things that are |
---|
23 | broken. |
---|
24 | |
---|
25 | Questions or comments should be directed at gutenbach@mit.edu |
---|
26 | |
---|
27 | NOTES: |
---|
28 | |
---|
29 | - If you keep getting zephyrs with the following errors: |
---|
30 | |
---|
31 | Playback completed with the following errors: |
---|
32 | bt_audio_service_open: connect() failed: Connection refused (111) |
---|
33 | bt_audio_service_open: connect() failed: Connection refused (111) |
---|
34 | bt_audio_service_open: connect() failed: Connection refused (111) |
---|
35 | |
---|
36 | This is because you have alsa configured for bluetooth, but |
---|
37 | bluetooth is not enabled. You should either enable bluetooth, or |
---|
38 | uninstall the bluez-alsa package. |
---|
39 | |
---|
40 | - The commands to print and remove jobs should be used via the scripts |
---|
41 | in gutenbach-client package. However, if you insist on using them, |
---|
42 | the correct syntax is: |
---|
43 | |
---|
44 | CUPS_SERVER=servername lp -dqueuename foo.mp3 |
---|
45 | CUPS_SERVER=servername cancel [ID|-a] queuename |
---|
46 | |
---|
47 | TODO: |
---|
48 | |
---|
49 | - include mixer and channel in debconf, or even better, move it to |
---|
50 | gutenbach-remctl and implement debconf in that package |
---|
51 | |
---|
52 | - this should really not conflict with pulse (the biggest problem at |
---|
53 | the moment is that pulse will spew a bunch of errors like "Home |
---|
54 | directory /var/spool/cups/tmp not ours." I can't figure out how to |
---|
55 | get rid of them, but they're really annoying. As long as pulse is |
---|
56 | in system mode, things seem to work otherwise.) |
---|
57 | |
---|
58 | - CUPS issues |
---|
59 | |
---|
60 | * the CUPS daemon processes do not inherit groups from the lp user |
---|
61 | (so, for example, even if we add 'lp' to 'audio', the process |
---|
62 | will not be running in group 'audio'). For the time being, I've |
---|
63 | set the CUPS daemon to always run under group 'audio', but there |
---|
64 | should really be a better solution. |
---|
65 | |
---|
66 | * when the Purge-Jobs command is sent, the jobs are removed, but |
---|
67 | the current mplayer instance continues playing. This |
---|
68 | unfortunately leads to jobs being played over each other when |
---|
69 | the CUPS server restarts |
---|
70 | |
---|
71 | - Making it easier to use across multiple platforms, regardless of |
---|
72 | debathena/normal linux/etc? |
---|
73 | |
---|
74 | - Gutenbach should not depend on Debathena -- ideally, |
---|
75 | gutenbach-server should be debathena free, and then if people want |
---|
76 | to use zephyr, etc., they can install an additional gutenbach-zephyr |
---|
77 | package or something |
---|
78 | |
---|
79 | - add regex support to the client scripts, so you can do something |
---|
80 | like `gbr sipbmp3 *.mp3` and have it send separate jobs to the queue |
---|
81 | |
---|
82 | - fix the web interface |
---|
83 | |
---|
84 | - fix the youtube feature. Additionally, make it possible to play |
---|
85 | movies! |
