ROKU SDK...SceneGraph

So who on this forum is going to begin the learning curve of scenegraph? Any tips? I have many channels I need to change over that are subscription based on the old sdk so I guess it's back to the other forum. Since DP does not allow for subscription channels to be easily converted, it looks like it's back to the drawing board to begin again with a whole new sdk of which it seems I have no choice if I want to keep my subscription channels. I know ROKU has some of the best in the business working for them but why won't they make it easier to change over the subscription channels..I wish I knew. Guess it's just not priority for us small fish in the pond. Smiley Sad     As much as I like ROKU. I've told so many people about them. I sure wish they would add the subscription option to DP. They are a talented bunch of coders and it would be so easy for them to add it.

Re: ROKU SDK...SceneGraph

I am trying to learn SceneGraph.  I like the DP concept and it is good to get a channel up and running quickly, but there are some things that it just can't do. 
I am familiar with PHP and some Python(not an expert by any stretch), but SceneGraph is a whole nuther ball of wax. It doesn't appear to be very intuitive, and the sample channels don't really do anything.  None of them have auto play features, in fact very few of them actually have any videos, and the explanation in the SDK documentation is generally written by and for people who already have some grasp of the information. 
I wish that there was something that just had the bare minimum of files and said 'this is all you need', but I haven't gotten even that much figured out.  I have been able to modify what is provided in an example channel and make it look like mine, but that's it. I guess that's all that I need isn't it.

Great! At least you have been able to modify one. Do you have the one you modified playing your videos? That's a big step. I have not gotten to that yet. I have been reading and researching. Time to begin digging into it. Such a learning curve. Almost makes me feel like they want to phase out those like myself that are not the "big box" channels. 
Here's what I found that might just be of help to me and I'll share it here in case it will be of help to others in the same situation I am ie: change over my subscription channels by the deadline of loose them all Smiley Sad    https://github.com/learnroku/crash-course

Tim, 
Which example channel are you using?
Thanks.

Re: ROKU SDK...SceneGraph

I have been playing with the "VideoList" channel.  This is the documentation page that discusses it.  I have been able to modify the image and the blank spaces for the main screen image and added my own list of videos, that was the easiest part. There are a lot of things in that coding that I am thinking don't need to be there.  I am also trying to get the list to automatically play the next video. I guess that is "autoplay" but there isn't a lot of discussion about that in the documentation.
I think that the down and dirty Roku class that you mentioned above is kind of outdated.  There are at least a couple things that are deprecated in the first two lessons, so it's slower going that I had hoped, I'm trying to get rid of error messages. I do appreciate the course, it's much easier to understand the struggling through the SDK docs.  
I have found that the Eclipse Roku Plugin is really helpful and so is the Atom text editor plugin for Roku Deploy and Roku Develop.

Re: ROKU SDK...SceneGraph

There are two zip files with similar names:
https://sdkdocs.roku.com/download/attac ... 110&api=v2
and
https://sdkdocs.roku.com/download/attac ... 910&api=v2
I am actually using the second one:  VideoListExample.zip  that one has several videos that you select and play.  I like the immediate play of the first one, but it only has one video so I'm not sure how to add a list of videos to that kind of immediate play. Still working that out.

Thank you for the help. I also came across the videoplayer master example to be used to migrate channels. I was just reading about it before opening your reply. I'll look over the links. Thanks much.
