Slimserver fails to play streams without .mp3/.mp2/etc. ending in the url

[Hypfer]

@ulope see tvheadend/tvheadend#888

No idea if or when they will merge, though...

[mherger]

I'm not familiar with tvheadend and cvlc at all. But what would you get if you used "curl -vI http://..." to request your URL?

LMS needs to somehow learn what your stream is. Either by its extension or by a content-type header. Otherwise it can't play it.

[Hypfer]

Server: HTS/tvheadend
Cache-Control: no-cache
Connection: Close
Content-Type: audio/mp2t

A content type header is set. Maybe LMS doesn't know mp2t? (It can play it, though.)

[mherger]

Yep, that type would not be recognized. You could add it though:

• find the file types.conf within the LMS installation (location depends on your OS)
• create a file called custom-types.conf in that same folder
• add the following line:

mp3       mp2,mp3         audio/mp2t     audio

Make sure you don't have any whitespace except between those three fields ID, extension, content type, and media type. Then restart LMS and try again.

You could get more information by setting logging for player.streaming.direct and player.streaming.remote to debug.

[Hypfer]

Okay so it at least tries to play the stream now, however it's not remotely sounding like music. Just some audio glitches with silence inbetween.

Does this have anything todo with the glitching or do I need to set some other logging feature to verbose?

Tvheadend streams take some time before they work like they should. mplayer for example spams me with cache not filling messages before it starts playing. Could that be related?

Ok, I did some more reading. mp2t actually isn't an audio format, but a transport format (http://www.w3.org/2013/12/byte-stream-format-registry/mp2t-byte-stream-format.html). Why don't you just use the URL which tells it to stream the actual audio data?

[Hypfer]

Because there is none. I was just able to do that by manually putting a vlc instance as a proxy inbetween.

Even though tvheadend does contain a transcoding feature, it can only transcode into container formats. Those being mp2t, mkv and webm. Would it be better to use one of those?

[mherger]

I'm sorry, that's out of my scope. You better join forums.slimdevices.com. There are many users who have done things I've never even thought of. Maybe someone will be able to help you there?

[Hypfer]

I'm making progress I think.

Using the MPEG-PS (DVD) container, LMS plays the stream without editing the conf file.
However, apparently it can't handle what I think is metadata/EPG-information in the stream and it tries to play that, too which means some periodic disorted noises. Or maybe its just the container information. Not sure about that. Running strings on the audio stream returns no normal text but I'm not sure if that means anything.

I think this is in the scope of the LMS. The Content-Type is audio/mpeg and so it should work.
No error messages playing that stream so apparently it doesn't even know that the data its interpreting as audio is in fact not audio at all.

[ulope]

@Hypfer Have you found a solution to this? I'm currently switching from VDR (which worked fine with LMS but had many other problems) to tvheadend and am struggling with the same problems.

[Hypfer]

TVHeadend just merged the PR.
