Resolution Note:
The number of clips that can be played concurrently on Android devices is dependent on their capability. Exceeding capabilities can lead to stutter. Workarounds for these situations include:
* Care should be taken at using the smallest resolution and frame rate that is acceptable in the context.
* Another authoring trick would be to have a single movie file that contains all 3 streams concatenated side by side (doable with external tools like ffmpeg). At playback time, one can manipulate texture coordinates to extract the wanted subparts and place them in the right location in the scene.
* The "skip on drop" setting could also be turned off. When enabled, this setting forces the VideoPlayer to skip-ahead if it falls a bit behind. This procedure can be costly depending how the keyframes are laid out in the video.
* Having more keyframes in the video could be of help here if skip on drop is to be kept enabled.
