When it comes to Lightfield video, we have broadly have two supported formats right now: SBS and Quad.
Quad really only comes in one format (because we are the only ones using it), and that’s a full width 2x2.
As I’m sure you may have seen, there are a variety of other stereoscopic 3D formats. SBS is just one of them. There are also two other popular methods of encoding 3D information on legacy devices like 3D TVs, and those include options like TB (Top-Bottom) and Frame-packed.
SBS is of course the most popular. There are two major kinds of SBS: Full-width and Half-width. Of course, Half-width was designed for particular 3D TVs in which using Full-width would actually REDUCE your usable resolution, and Half-width was the best method to get the most out of the pixels on your display.
Full-width is of course by far the most popular method. In the past, RED Player and LeiaPlayer would guess whether the content was Full-width or Half-width based on it’s resolution. This would sometimes cause problems for some Full-width content that’s accidentally thought to be Half-width (like some Portrait orientation content) and vice versa.
The new version of LeiaPlayer corrects this, and instead all content is assumed to be Full-width, and in the rare cases it’s not, the user has to change the naming scheme to add “half” to the filename as in “filename_half_2x1.mp4”. Our data shows that a tiny fraction of our users are using Half-width content.
The new version of LeiaPlayer has the same compatibility as the last version, with a slight change to make life easier for users the majority of the time.
There are two simple solutions for you:
- Add “half” to the filename of the Half-width content you’re having issues with.
- Use the older version of the app that seems to work for you.
