mdd on masterbackend

[GoogleCodeExporter]

Which version of MythDroid were you using?
0.5.2

Which version of MDD?
0.5.2

Which version of MythTV were you using? (e.g. mythfrontend --version)
Master Backend only 0.23 

What steps will reproduce the problem?
1. Try to play a recording to 'here'

What is the expected output? What do you see instead?
Recording plays on the phone.

Instead I get "Connection refused to 192.168.xx.xx:16546"

Please provide any additional information below.

Headless MBE in loft.

I believe I correctly installed mdd on MBE, but can not find a running process 
for it. I can run 'sudo ./Build uninstall' and it appears to uninstall 
correctly.
'sudo service mdd restart' seems to restart the service.
mythlcdserver is NOT installed, as this is a backend only, and I am wondering 
if this is the problem?

Also when I try to schedule a recording (the guide seems to work fine) I get 
'Failed to connect to MDD on 192.168.xx.xx.

Does this mean mdd is not running? If so, how do I get it running correctly 
without having to install mythtv-frontend to get mythlcdserver?

Remote of both frontends seems to work OK so far (couple of permission errors 
but no probs to fix)

The errors do suggest that mdd isn't running but MDD doesn't attempt to start 
mythlcdserver when it's running in backend-only mode so this shouldn't be the 
problem. Try running mdd in debug mode (mdd.pl -d) and then have a look at 
/tmp/mdd.log. Attach the logfile here if the problem isn't obvious.

OK - mdd certainly wasn't running correctly, but...

chris@mythmaster:~$ sudo service mdd stop
mdd stop/waiting

...it kinda was running!?!?

chris@mythmaster:~$ sudo mdd.pl -d
Can't locate Image/Imlib2.pm in @INC (@INC contains: /etc/perl 
/usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 
/usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10

BEGIN failed--compilation aborted at /usr/bin/mdd.pl line 41.
chris@mythmaster:~$ sudo nano /usr/share/perl5/MDD/HTTPServer.pm

So, I installed libimlib2 & libimage-imlib2-perl
& the install script did its magic, and I now get 'mdd.pl' as a service.

I was under the impression that the Imlib2.pm error during the ./Build test did 
not matter, but it seems it does. (I'll go fix it on the frontends as well, 
just in case)

Thanks for your help foobum- at least mdd is now working as it should, just 
scheduled a program using the guide - off to sort out the vlc streaming errors 
now (may be back later).

ps- fantastic app, will go a long way to improve the WAF - she'll be able to 
control all the frontends with the same remote, and she should NEVER lose it ;-)

OK problem with videos (not the recording issue - I think that's a vlc problem)

That was the o/p when I selected 'Videos' on the phone.
When I select a video, no o/p in log.
When I hit play, I get a popup "Connection refused to 192.168.xx.xx:16546"
and Mythdroid politely tells me "Sorry, this video cannot be played"

O/p in log at this point is:
sh: Syntax error: "(" unexpected

Any pointers?

Could you attach logs please? mdd's log can be found in /tmp/mdd.log. If 
possible, the relevant logcat output from the device would also be useful. 
Thanks.

Hopefully, this should be what you're looking for.

Not sure if it matters, but Im running a Samsung Galaxy mini with CM7 firmware 
and the master backend is ubuntu 10.04 server (minimal install, with bits added 
as needed).

Cheers.

Thanks for the logs. Easily fixed by escaping shell meta-characters in video 
file names. Commit imminent..

So, I installed the patches (thanks) and installed ffmpeg & codecs from 
medibuntu repo, and we seem to be making grand progress. I can stream videos to 
the handset - audio perfect - video bit suspect! - what is recommended backend 
spec for streaming to android?

Only problem (think its still related) is streaming recordings to handset - 
get the popup as with videos "Connection refused to 192.168.xx.xx:16546" - was 
sure it politely told me again "Sorry, this video cannot be played", but can't 
reproduce that.

Logs attached again.

Thanks again for all your hard work and excellent app.

You do need a reasonable cpu on the backend. I use a dual-core Athlon64 and can 
happily encode 448 kbps but not 1024 kbps. The more cores the better. An atom 
is unlikely to cope. Lower bitrates require less horsepower..

So the problem is that the RTSP connection to VLC is being refused, which 
suggests that VLC has had a problem or is just being very slow to start the 
stream.. Could you post one more log please? /tmp/vlc.out should tell us what's 
going on..

OK - to get this log mythdroid DID tell me "Sorry, this video cannot be played" 
as well as the popup.

MBE is 2.66ghz celeron with 512MB. :-o
Only trying to stream 192 to handset - hopefully its not the hardware causing 
problems.

The VLC output looks ok. So, I guess it's that VLC is taking a long time to 
start the stream (we already wait for a rather long time before accessing it). 
I've just committed a potential fix, which causes us to attempt the RTSP 
connection three times before giving up. Perhaps you could test the trunk 
version of MythDroid?

No problem - how is the best way to go about that?

I guess I can use adb to push the file to the device? Where is it located in 
the file system? I have no 'locate' in the adb shell!
I am currently sat with a windows laptop, but can use a linux box if it's 
easier. 

Cheers.

(I also wonder if this may help issue 53)

Looks like r580 & r590 has solved the problem.
Thank for all your help with this, foobum.
