HLS on Smart TV

I tested new Samsung SmartTV with Tizen 2.3 and Samsung Browser 1.0/TV/Safari 538.1.

First I tested 3rd party input and it worked: http://ocko-live.service.cdn.cra.cz/playlist/live/ocko_expres/live_hq.m3u8

So I put our stream from Wowza (nearly basic settings, only few changes): http://stream10.idnes.cz:1935/live/slowtv7/playlist.m3u8

But it didn’t work.

Is there any setting which I should apply?

Hello there and welcome to the wowza support forum.

Can you please provide more detail about your set up?

What is the source of the stream?

What are the video/audio codec of the stream?

What, if any messages or errors do you get when trying to connect to the stream? You can start Wowza stand-alone mode (install-dir/bin/startup.bat|startup.sh) and view the output in the console.

Thank you.

Thanks for the update on this thread and solution.

Hi,

It could be related to the source. We can’t guarantee that all Wowza Playback Types will be compatible with devices such as smart TVs.

A quick way to test is (in the smart tv browser) open the sample file that’s provided as part of a standard install, e.g.

HLS

http://[wowza-ip]:1935/vod/sample.mp4/playlist.m3u8

RTMP (Flash)

rtmtp://[wowza-ip]:1935/vod/sample.mp4

If it doesn’t stream then the limitation is likely to be due to the smart tv.

Hi,

I’m not sure how to debug this with regards to a smart TV. If the HLS of sample.mp4 plays and the HLS of the one titled “slow” doesn’t then it may be codec related. You can test this with something like Chrome, enable the JavaScript console, and see what codecs are reported. Alternatively, try passing the streams through the Wowza Transcoder (the source will need to be a live stream, so the Stream Publisher may be required).

Source is incomming rtmp stream. We use some Applications, mainly Apple HLS for flash video element and mobile devices.

Stream is working fine on apple devices (iOS, OS X Safari) and in flash, but we realised problem on smart tvs (Samsung, LG)

You think it has something to do with incomming stream? But same stream is working fine on youtube (https://www.youtube.com/watch?v=yqUKgAyRmh0), we have problems only through wowza.

Our settings:

live

You’re right, it is probably related to the source:

http://gidnes.cz/test/catt/videoplayer/flash-streamy.html

First one (http://stream10.idnes.cz:1935/vod/sample.mp4/playlist.m3u8) plays, but one titled “slow” doesnt.

Can you please help me how to debug this issue?

Hi,

we use Adobe Flash streamer with theese settings. My question is simple - what change to enable stream on smart tvs - I guess that maybe change baseline into 3.0, but i’m not sure…

I found it! Samsung Tizen only support HLS v.3, not 4

Thanks for the valuable advice, that’s what I was looking for

Hello, where to adjust this in wowza?
