[Tizen] Stream playback issues & limitation

There are several restrictions in order to play streams on Tizen display:

Multicast address​

Supported IP range 234.0.0.0 to 238.255.255.255 for streaming

UNsupported IP range 224.x.x.x & 239.x.x.x DO NOT use these ranges for multicast streams on Tizen

Bandwidth Requirement​

  • Streams in SD (640 X 480) require approx. 3-4 Mbps
  • Streams in HD (1920 x 1080) require approx. 5-8 Mbps

Passing URL to JS SDK​

The URL with the stream HAS to include the protocol while passing it to streaming JS SDK

  • RTP stream URL MUST start with rtp://<IP>:<PORT>
  • UDP stream URL MUST start udp://<IP>:<PORT>

You cannot mix video playback and streaming​

  • Streaming is limited to 1 playback at 1 screen.
  • Streaming + video playback is NOT supported on 1 screen
warning

Due to this limitation you HAVE TO use a special signageOS Core App for Tizen that supports streaming.

Current version is 2.12.0-streams.5944:tizen-streaming-app.png This special application can be installed via Box (image above) or via REST API by using the version above.

UHD streaming​

To be able to play video stream in UHD resolution on Tizen device you have to stream .ts files without transcoding.
