[SlimDevices: SqueezeCenter] Streaming (Audio) from Enigma2 Receiver

[Simon74]

Hello i like play Radio Streams over DVB-S from my openPLI Enigma2 Box.

When i save the URL from Stream under Favorites then is the Problem the
empty extension:
-http://enigmabox:8001/1:0:2:3176:459:1:C00000:0:0:0:-

Ok i can get a URL with extension from openwebif, that URL can i save.
-http://user:***@enigmabox/web/stream.m3u?ref=1:0:2:3176:459:1:C00000:0:0:0:-

Then the next Problem, when i start the Audiostream becomes the error:
-Playlist is empty -

On VLC Player run the Audiostream.
Codec Info from VLC:
18838

Is this Codec the Problem ?
in Log i not see errors

The audio format of a stream is determined by LMS from the extension
and/or MIME.

Since you have no extension - what is the MIME type for the http stream
that is sent by your enigma2 (i.e. the value of Content-Type in the http
header )

There are two issues

1. MIME is video/mpeg
2. Codec is MP2 in an MPEG-TS container - this is not simple http/MP3 -
I think the "proper way " to support this stream would to be to create a
plugin

There are two problems
1. Supporting MPEG-TS - I think only the LMS MP4 support handles this
but not sure if it can handle a non AAC codec.
2. Supporting MP2 - not sure if all players upport ddcoding MP2 - I know
the older IP3K based player such as SB2/SB3/Class/Boom can.

Suggestions

Is it not possible to get OpenPLi enigma2 to send a nicer formatted
stream (e.g. strip mpeg-ts and use "raw" plain http) ? as I understand
it, it is a highly customisable linux box

To tell LMS the video/mpeg is supported you can create a
custom-types.conf file in the same directory as the LMS types.conf. Try
creating the custom-types.conf file with ONE of the following lines and
restart LMS. And then try to play your stream - personally I don't
think ti will work.
mp4 m4a,mp4,m4b audio/m4a,audio/x-m4a,audio/mp4 audio,
video/mpeg
mp3 mp2,mp3
audio/mpeg,audio/mp3,audio/mp3s,audio/x-mpeg,audio/mpeg3,audio/mpg
audio, video/mpeg

Since VLC can play this stream you could install the playDASH plugin
(which uses VLC to play DASH streams) and then modify the PlayDASH
custom-types.conf file to support video/mpeg. However I haven't tested
playDASH but it is a mod of my playHLS plugin which couldbe similarly
modified if your stream can be played with ffmpeg.

What system does you LMS run on ?
The modded PlayDASH or PlayHLS seems to be the way the go.

Can you play your stream with ffmpeg ? If so I can help with changes to
playHLS.

The format is still MP2 not MP3 - check if you can play this file on
your Squeezebox baby radio ? I think it should work.

OK

Install PlayHLS plugin - and check that it works by playing a m3u8
stream. There are differences betrween various linux distro regarding
ffmpeg and avconv which may be the problem.

Down load the attached zip file. and unzip into the PlayHLS directory -
the 3 files should replace the existing PlayHS files.

Restart LMS and you should now have a ENM2 file type under
Setting/Advanced/Filetypes. It is setup to use ffmpeg. If diesbaled
then ffmpeg isnot on your system.

The custom-convert.conf file controls the ffmpeg options to use when
converting the input stream.
The PlayHLS custom-types.conf file now has the video/mpeg type - so you
shoudl remove any changes or files you made earlier.

I cant' get back to this this later today so you may prefer to wait.

LMS is using ffmpeg to play the stream. You should be able to see this
process and the command line when it is playing. When you stop playing
this ffmpeg process should die. When you start playing the new Favorite
is the original ffmpeg process running (i.e. do you have two ffmpeg
processes running ?) What is the difference between the two URLs ?

Since you ffmpeg processes are not dying - I think the problem is with
the build of ffmpeg but IIRC there may be a LMS contributing factor. I
think there are a few workarounds - I'll see if I can find them. What
version of LMS are you using ?

Before I chase solutions - are you sure there are two different parent

There are two solution proposed by different users about how to kill
persistent ffmpeg processes.

1. This one suggests changing LMS file bootstrap.pm
http://forums.slimdevices.com/showthread.php?103158-Announce-PlayHLS-Plugin-plugin-to-play-Apple-HLS-m3u8-stream&p=809208&viewfull=1#post809208
If this change works - remember it may need to be applied each time
LMS is updated.

2. The second solution relies on a wrapper around the ffmpeg program -
the wrapper makes sure ffmpeg processed is killed when playing has
stopped. In the plugins custom-convert.conf file - the name of the
program is with square brackets (i.e. [ffmpeg]). LMS looks for the
program in the Plugin Bin directory and then on the PATH. This solution
relies on putting a Perl script called playhls.pl into the Plugin Bin
directory (it is not a good idea to use /usr/local/bin as suggested)
and making it executable. Then change the "[ffmpeg]" into
"[playhls.pl]" in the custom-convert.conf file and then restart LMS.
The playhls.pl script and details can be found here.

Hallo bpa,

your plugin for hls and for the ENIGMA2 based videorecorders is great!!!

It works also for DREAMBOX 920 devices.

Thanky you very much.

The SAT Radio streams are MP2 codec.

So I changed your custom-convert.conf from


Code:

enm2 flc * *
# # RB:{BITRATE=-B %B}T:{START=-ss %s}
# [ffmpeg] -loglevel quiet -i $FILE$ -f flac -
