Maximum supported frame rate on Samsung Tizen Displays
Samsung Tizen panels do not currently support frame rates above 30fps. You will need to reencode any video content above this frame rate in order to display it on any Samsung Tizen display. You can learn more about encoding your media files, here.
Playing Multiple videos concurrently
Only one video is able to play at a time, this is because the SSSP has one video decoder that can only decode one stream at a time.
Please note that 'video' in this context refers to video files, IPTV streams and HDMI input.
If there are two zones with videos in the video will be played on a first come first serve basis, i.e. the zone that requests it first will play the video. If for example, there are two zones with entirely videos in one of the zones will not be able to play its videos and will display black.
Video zones overlaid over other content zones
If video content is overlaid over 'other' content zones it will not display as the SSSP application is unable currently to make the transparent cut through the content within the zone required to display the video. This is because the video layer is below all other layers so in the 'standard' scenario e.g. no overlapping zones the background image is cut out, however, this is not currently possible with scheduled zones. In order to work around this please use PNG's and cut out the required area with a transparent section.
Smoothness of Ticker
To ensure the ticker is smooth it refreshes 16 times per second (approximately 60Hz), if there is another process such as a content download or asset in a zone loading this will have an effect on the ticker as CPU cycles are taken away from the ticker. This effect should only be temporary whilst the other operation is executing.
In order to limit the effect of this, it is recommended to have the content check as infrequent as possible to limit the occurrences of this occurring and carefully consider the design of the content and playlists, adding lots of zones will have a detrimental effect on the performance of the ticker.
Note that ticker performance is greatly improved if using a fade rather than an animation.
It is rumoured that Samsung will be introducing hardware acceleration in future models of the SSSP as they have this available with Smart TV's which will defer all animation rendering to the GPU eliminating this limitation.
Playing a video after HDMI input
After the SSSP has rendered the HDMI input, it may take up to a second for a video that is next in the playlist to start playing, during this time the screen (if fullscreen) or zone will display black. The reason for this is that the panel is switching inputs between HDMI and the internal media input.
Screen and Audio Settings
It is not possible to set the settings such as brightness, contrast and audio settings whilst the SSSP is running. Note that if a video is playing you will be able to, however, this will only affect the screen area where the video is playing not the entire screen - This is a bug in the Samsung firmware. Currently, it is also not possible to set these settings via the Samsung SDK as they do not work, this is logged with Samsung as a defect. If you need to set the audio settings switch to another input and make the changes there as they are global and then reset the panel.
Running Videos in Portrait
When portrait support is added to the SSSP all video content will need to be rotated appropriately before publishing to the SSSP, this is because the video decoder does not support rotation. Please note that 'video' in this context refers to video files, IPTV streams and HDMI, therefore if a streaming format is required to be used in portrait a third party piece of hardware that rotates the stream must be between the source and the
Note that all other content will rotate correctly as this is accomplished in the HTML layer which is independent of the video processing.
