Gapless Playback Support webOS

Gapless Playback is supported in webOS from v4 R407

It should be noted that gapless playback capabilities between Widgets will vary when:

• Widgets are added to play in a sequence.

  or
• Widgets are added to different Layouts to play one after the other when either scheduled as separate Layouts or included as part of a Campaign.

Widgets set in Sequence

Widgets should be added after a Widget of the same type for best results:

• HTML
• HTML Package
• Image
• Local Video
• Video
• Video-In

However, there are still sequences where certain Widgets will show black frames as shown in the matrix below:

There are still limitations to this which are detailed in the matrix below:
