Play "here" mythbuntu:15647 connection refused

[John C]

Have only now tried streaming to my android (galaxy tab). I get
"http://192.168.2.44:15647 connection refused". Is there something
else I need to enable/turn on?

Thanks,
John

Hi,

Do you mean 16547? That should be vlc's rc interface. A failure to connect to that shouldn't stop the video playing but you won't be able to seek, etc.

Have a look at /tmp/vlc.out for clues as to what's going wrong..

1) vlc wasn't running because I run mythfrontend as user "john" and
the vlc command could not write to /var/log. I just changed it to
write to /tmp/mddvlc.log and that got that

2) mdd.pl (0.5.2). findFileSG for some reason was looking for /var/
lib/mythtv/recordings1038_20111202210100.mpg [note no slash] instead
of /var/lib/mythtv/recordings/1038_20111202210100.mpg. So I hacked to
look for "$d/$file" instead of "$d$file".

3) It streams video to the Android now, but no audio. mdd.log shows:

I am not at all a vlc or streaming guru so do you have any tip?

I think I am running mythdroid 0.5.2 apk (Nov 15)

Thanks!
John

Hm. It should write to /tmp/vlc.out by default, not into /var/log...

Ok, thanks for that. I thought that all SG dirs have trailing '/'s but a check is trivial - I'll add one.

Looks like you're missing an AAC (MP4A) encoder - you probably need to enable one at (vlc) compile time.

Thanks foobum! See below.

Oh, my bad, it seems I had patched mdd to (attempt to) write to /var/
log!!

I've been browsing 17 pages of discussion at http://ubuntuforums.org/showthread.php?t=1117283
and
conclude that it's way over my head and I can't afford to risk messing
up my mythtv installation and
try to recover from it right now.

I realize you're not the right person to ask but are there any audio
codec encoding alternatives that
would likely play on my galaxy tab and LG optimus S that are not
"restricted"?

Cheers,
John

John,

Using ubuntu, you need to uninstall ffmpeg. Enable the medibuntu repostitry, then install ffmpeg from there. I'll double check, but I think thats all I did to get it working.

[minidroidboy]

I also had to install libavcodec-extra-52 in 10.04. I believe for any
higher version of ubuntu you need to install libavcodec-extra-53.

Hope you get it working.

I think, as Chris said, you just need to enable the medibuntu repository, uninstall vlc and ffmpeg and then reinstall them..

Well, you'd need a codec that a) you can encode b) vlc can send via rtp and c) is supported by your device.

You can see what you can encode with:

vlc -l | grep encode

+

ffmpeg -formats | grep 'E '

You can see what formats can be sent via RTP at http://www.videolan.org/streaming-features.html

The specs for your device should list what codecs it can decode..

But, I'd recommend just getting yourself a vlc and ffmpeg that can encode aac..

foobum
