I am developing a video player on the LG webOS tv platform. I have trouble with (pre)loading the data on LG WebOS 4.0 displays.
I read in the HCAP documentation that there is a specific video and app layer, and that a video needs 0.5 seconds to load. This is too long for us, so we preload. This way, we load a video while another is playing, but after loading the next video, we get a few frames of incorrect video output.
This always triggers on the video onloadeddata event of the HTML5 video tag of the preloader but is visible on the actual video player tag. The LG WebOS 6.0 and Windows players do not have noticeable visual issues with this.
I only use the webosTv.js library and not HCAP, but I suspect it has something to do with it (it seems like a kind of lock on the video memory, which is reclaimed by the actual video in the next frame or something). The white flash is actually green data (memory issue? I also see green data through it, see the attached photo) that I am currently trying to mask as much as possible with JavaScript / css.
Is this a known issue, or does someone have tips to remove and/or debug these green/white flashes without having to revert to a single player and wait 0.5 seconds each time?
