Request: Add an Instant Transition [SOLVED]

@cafarellidigital said in Request: Add an Instant Transition:

Whichever system encounters the static first, that's the one it uses.

If you were going to have a static image, you would not have more than one background specified. In the main .xml for the theme you would have the system background called out one time to a single location in the .art folder, or wherever theme creator places it. You would not call this out again anywhere in the theme, so you wouldn't need a static tag. This is true for any element you would want to stay in the same location for every system. Simply call it out once in the main .xml and it won't move. This is how it works now, but ES reloads the same image The only thing that needs to be done is to have Emulationstation not reload the image when system is switched so that it does not fade or slide. I agree with you, not sure how to do it, or how easy that might be?

I agree, you won't have more than one background specified because you would put it in the main/common xml, but technically that main/common xml is "included" in each system xml, so that line of code would appear on any and every system.

The reason I would want a static tag is because it might be useful to have this happen with only one or a few elements in the view. Without a tag, you could not specify only certain elements to have this function.

For instance, in the system view, say I had a background and a custom help legend that never changed, no matter what system you were on. However, I also have an outline of the system controller above the system logo, which obviously changes for every system.

What I would want is for the background and help legend to not slide/fade when you change systems, but the controller outline would. You could only do this if you could define which elements were static and which were not. By default no elements would be static.

TMNTturtlguy

@cafarellidigital so your not really asking for a new transition at all, you still want some elements to transition, you just want some elements static and not to be effected by the transition.

cafarellidigital

@TMNTturtlguy correct. At first thought the idea of a new "instant" transition was great, then as I thought about it, I realized what I really wanted was a new function/tag that elements could have. So I guess I hijacked the thread a bit didn't I?

@cafarellidigital Hijack away! It's the same goal in the end.

@Capeman Would you be interested in testing ?

I have pushed changes correspoding to No Transition/Animation to my repo:

https://github.com/hex007/EmulationStation

@Hex can you provide me with some more information on what is in your build? How up to date is it with the main ES build? Thanks

Hex

As of now it is 4 commits behind. Those commits were pushed today i guess.

The build is optimised for Pi zero and 1. Has problems with video as the program sleeps till user input.

Has music player incorporated for which you have to follow some instructions to get running. If you are testing on Linux and not Pi then you will have to change "audio-server/player.py" file to change music directory.

I have added None as a Transition today.

Thats all

TMNTturtlguy

@Hex Right now all of my gamelists have video, should i avoid testing at this point?

Hex

@TMNTturtlguy You can test it. Just that I dont know how it might behave. Only two options either the video continues playing or it stops after some time. It certainly wont crash or damage your lists/data

On the plus side if it works I will put it on the Readme that videos work

TMNTturtlguy

@Hex I just ran through your build. I have to say the theme transition NONE, is pretty slick. My only question is if it would be possible to allow the carousel to still transition. I like the static background, but and the carousel images pop up really fast, so it isn't an issue, but i think it would look really cool if the carousel logos could slide or fade over the static backdrop. As for videos, the videos played for 2 seconds and just paused. No other performance issues, they just paused.

I would seriously consider making a branch of the main ES Build and only incorporating the NONE transition into it. Like I said, if he carousel could still transition, it would be perfect. If you isolate this update and submit a PR, a lot of people would be really excited about it.

Thanks for the awesome work

@Hex would you consider bringing your changes over to the main repository? The optimizations could come either as a compilation option (if compiled on a pi zero or 1), emulationstation option (for users to select) and/or command line option (and have RetroPie Setup add that option on a pi zero or 1 to the emulationstation startup script).

The rest could come as normal options for everyone.

I suspect that'd be the best to avoid fragmentation, bring your work to a wider audience and bring another good emulationstation developer to the project.

Do consider that. Happy to help.

Also, you could certainly make videos work by forcing the screen to refresh in the video view only, which I agree isn't needed for anywhere else on emulationstation as everything is static.

Oh, and that won't be an issue with OMX player, as rendering is handled in a separate process.

Still, good work!

Hex

@TMNTturtlguy I will try that tomorrow. Also read ahead.

@pjft If you have a Pi Zero or 1, I would appreciate if you can measure CPU consumption of Emulation station (mine and stock) when doing nothing on Carousel.

ssh into Pi
top

I noticed a constant ~60% usage on the stock on pi zero

pjft

@Hex I don't have one, but I notice similar regular CPU consumption (unsure if at 60%, but certainly not idle) when emulationstation is idle. I haven't read your code but from what you described you're avoiding refreshing the screen - including reading and processing the textures - unless there's an input. That's a wise change, as very little of it is animated. You probably have a few seconds of buffer to accommodate animations, inferring from the fact that videos play for a few seconds.

The reasons video views would need to be refreshed is because they are rendered in a normal texture, so if emulationstation doesn't refresh the screen it won't render more frames.

But for the time being that's the only exception that comes to mind.

@pjft Can you update the clone and test it? I have set it to disable powersavings if Videos are present.

jdrassa

@Hex I haven't tested it yet, but I don't think the power saver flag is going to work properly. On startup, getGameListView is called for each system and the view is cached. As implemented, I believe the power saver flag will be set based on the last view created vs. the current view. Instead of setting and returning a boolean, you could test the name of mCurrentView to see if it is video.

jdrassa

@TMNTturtlguy I agree changing the view transition style shouldn't effect the animation in the carousel itself.

Hex

@jdrassa Can you test it. I dont have Videos so i cant test it. I will change the implementation if it doesn't work

jdrassa

@Hex I will try to get it tested in the next couple of days will report back.

TMNTturtlguy

@Hex did you make changes to the carousel transition or just the video playback? Thanks
