    Basic observations and information on how to use Wowza Server with Samsung Smart TV (formally called ConnectedTV).

    Several of the new 2011 Samsung TV models support Samsung Smart TV. There is more general information along with a list of TV models here:

    http://www.samsung.com/us/article/ap...lt-for-your-tv

    Smart TV support Flash player 10.1. This includes support for RTMP (and all of its variants), Flash HTTP (sanjosestreaming) and Apple HLS (cupertinostreaming). To get started I downloaded the Samsung TV Application SDK from here:

    http://www.samsungdforum.com/us

    The SDK includes an IDE and an emulator. It seems to be a pretty simple system that relies heavily on HTML, Javascript, CSS and XML. It looks like you can easily embed the Flash player in any of your application pages to support video playback. The documentation suggests that H.264/AAC-LC playback is accelerated and can play fullscreen.

    I do not have a Smart TV for testing. So this is all the information that I have at this time.

      You can play Flash as described in the \samples\client. Open your site using the web browser provided with the TV, Pre-Configure the client to enter default URL and UDP source to make things a bit easier since typing this information is tedious in using the remote controller. Video plays well, live or on demand.

      We're testing this now with a BD5300. For this we're using the sample code for HAS/HLS streaming. It works great in the emulator, but once we upload it to the Samsung device we're stuck. It makes the request to Wowza and we see it buffering, but there's just no video or audio. This is with a Live setup. VOD works great.

      To isolate the problem we're using the Big Buck Bunny 1500. For Live setup we stream from VLC to Wowza (rtp, ts) without any transcoding. Works great in both flash and on the ipad (hls). Will test a flash-player on the Samsung now, but would hate to have to use it, would really prefer the HLS method.

      I am facing the buffering issue with live HLS, I am sure it's an encoding issue, did anyone found a specific parameters need to be set for this ?

      For me this would make no sense, as I'm using the same file in a VOD and Live scenario and it works in VOD. Encoding should thus be the same, only mux would differ?

      Finally found some specs for this, googling skills working overtime!

      http://www.samsungdforum.com/Devtools/Spec

      Notably:
      * Different specs for emulator and hardware
      * Hardware VOD HLS streaming: Supported
      * Hardware VOD HLS adaptive streaming:HLS v2/MPEG2 TS only/AES-128
      * Hardware Live HLS streaming: HLS v3/MPEG2 TSonly/AES-128

      I do not know how different HLS versions work, are they backwards compatible? If Samsung supports v3 and Wowza is using v1, could this be the source of the problem?
