 |
|
Hi y'all,
OK - so I had a perfectly working mythbox untill I "emerged updated all deep newuse" and what ever it us called...that kind of screwed up my alsa or at least my myth sound config.
In mythtv setup under the general -> audio I have
'audio output device' = alsa
'Mixer Device' = /dev/mixer
this makes the sound on tv and movies work
In the Mythtv setup media settings -> music settings -> general settings
the 'audio device' is set to /dev/dsp
this gives a minimum of errors but it does not make it work. This is what I get:
| Code: | 2005-08-10 21:51:33.840 Opening audio device '/dev/dsp'.
2005-08-10 21:51:33.841 Opening OSS audio device '/dev/dsp'.
Decoder error. DecoderMAD: Failed to open input. Error 5. |
on the frontend I get a dialog saying almost the same - and no music....
I can play mp3 files using madplay, mplayer and mpg123 - what gives?
Any idea ???
I'd sure love to hear them !!!!!

Maybe you didn't compile your kernel with oss support or there are some other probs with your oss emulation.
Sound in mythtv and other apps are configured to use alsa, i think.
Try to set mythmusic's 'audio device' to 'ALSA:default', to use alsa there too. |

Hi Doc_23 and others
Do I really need OSS support to run MythMusic ???
I had the impression that the entire myth package only depended on ALSA.
I do have a USE flag saying -OSS.
Does MythMusic use the MADplayer ? I have tried to unmerge and merge the following without results:
-myhtmusic
-libmad
-madplayer

I have a similar problem. I thought that mythmusic would use the same audio device as the TV module. I can get my DVD, DVB etc to play ok. xine plays the mp3 ok but the mythmusic player doesn't.
What does mythmusic use to play music? |

You can set the output device for mythmusic in the setup menus somewhere, so try changing that.
Edit: Okay, that made no sense... Basically mythtv's "general" setup you put the output audio device for everything. But mythmusic you can also set the output device for just that module. You'll have to dig in the Setup menus somewhere to find where it is (I certainly can't remember), and you can change it in there. If you're using ALSA then change the device to "ALSA:default".

Oh man I suck. I didn't even see that setting in MythMusic. It all works fine for me now.
Thanks. |

| I read somewhere that it is because myth frontend does not have access to the media file - does not make sense to me....anybody else |

If I look through the source (http://wakeboard2.gonzalezfamily.org/devel/mfddocs/html/maddecoder_8cpp-source.html) I see this:
| Code: |
00116 if (! input()->isOpen()) {
00117 if (! input()->open(IO_ReadOnly)) {
00118 error("DecoderMAD: Failed to open input. Error " +
00119 QString::number(input()->status()) + ".");
00120 return FALSE;
00121 }
00122 }
|
(see link above for full code)
Can any of you code geeks help interprete...tell me how to move on |

OK I'm no c++ coder (at best I dabble in a little c) but this is what I make of it:
input() is an object that is the file you are trying to play. So line 116 is asking if the file is already open. If not then line 117 asks if it can open the file read only. If not then lines 118 and 119 are run which gives you the ouput.
So this does appear to be an access issue.
I got the same error myself. I checked the permissions and the files were owned (and readable and writable) by the mythtv user. So the perms were correct. What I found fixed the problem was to rebuild the mythmusic db by searching for new music.
Hope that helps.
Cheers

| I had the same problem. Simple fix, check the path where the music files are located. For some reason it has reset it self to the default path (and there are no music files located). |

I had the same error message tonight when I was moving some music around and forgot to "scan for new music".

I had the same error....because I had moved the audio files.
pretty silly error message really. It should say "this file no longer exists" or something a little more user friendly. |
