Hi Trausti, thanks again for finding what cause this problem and offering solution on your side by creating your own 'o2vr'...
I am actually split in half regarding to one file vs folder with files. I can see the point with handling files, etc. but I can also imagine it could be counter-productive. I mean when streaming user might not know if movie is still loading or if it has been loaded. In case of slow connection there is a risk that viewer could see just begining of the movie and could think that was it. If you know what I mean... On the other hand I could imagine situations where streaming is much better option. Personally I don't plan to use massive files just yet so at this stage I am leaning towards one file. But I am aware I might regret it in the near future. ...of course to have an option to choose either output would be the best solution for us (but not necessary for proggy, heh?)

Zoom, auto/manual rotation would be good for a start. I guess there would be still option of grabbing movie by mouse and spin it around, correct? Simple dropping numbered files is good enough and I don't think even in the future versions there would be need to changing files at all. Object2VR has a lot of options of setting the output size, quality, etc. but personally I prefer to do this in PS so I have 100% control over the files.
I have never used advanced features like hotspots and text fields. Woody is a master of using them but I reckon those are not in category "basics". Of course it would be great to have such a features in future versions. Same as possibility to add more than one row of photos so we could pan also up/down, not just left/right.
What I care more about is final output and options of embedding it into the FPP. I have NO idea how difficult would it be but I would rate highly if:
- there will be option of distort the movie
- there will be an option of using 'Alpha channel'. I mean to get rid of the background or unwanted parts of the picture. I assume its not as easy as using png files with alpha channel. But maybe it would be "easy" to have blend layer as we have for movies where black background is eliminated. If this is possible I think rather that black it would be great to use some strange colour which is not seen in nature very often, something like #ff00f0
That's what I could think of now. I am curious to see contribution from other users which might inspire me to have more requirements

Having said that simple thing as you described it would be more than what we could have wished for!
Thanks
Ondrej
btw If you plan further development of object player I dare say it should be paid add-on.
