Synthwave_city_4 animated background for E27

Users Corner Customizations

I used the E16 Retrowave wallpaper, adding some sparkly stars and a small shuttle that moves from right to left.
I'm currently updating my github, and will be posting my compositions there in the future. For those who want to try it in the meantime, follow this link.


Have a good day

Very nice but ultimately I'd go for different trajectories of the spacecraft in the upper half of the wallpaper ... or maybe even multiple craft.

I couldn't resist and played around with chroma-keys on a video (Star Trek).

Not meant as a wallpaper, just for the fun of it. :innocent:

Indeed it's much better, it's more dynamic. So I added 6 ships with random movement and size from right to left and left to right. Thanks for the advice.

Too good, I don't know how to do that in EDC yet. It's cool

I think that's overdone actually, it's not really nice.
The single ship is best, it just has to move from different positions IMO.

I'm sure there has to be a way to randomize the movements or use a .gif statically as an overlay.

Alas I have to get up at 04:30 tomorrow morning so I wont be looking too hard for a solution just yet.
I rendered the ship as a .gif but it doesn't keep transparency. :thinking:

Ship-2

What would be really cool IMO is a ship that comes in at enormous size from above flying over the onlooker and then flying away in the sunset until it's a dot. :happy:

I'll be checking SciFi clips for that .... I'm sure I've seen it somewhere .... 2001 Space Odyssey ??? :thinking:

Awake, unloading ship and playing too. :w00t:

Got the transparent .gif through 'ffmpeg' on the commandline:

ffmpeg -i Trek-vessel.mp4 -filter_complex "[0:v]chromakey=0x000000,split[v0][v1];[v0]palettegen[p];[v1][p]paletteuse" Trans-vessel.gif
  • Where 0x000000 is HTML #000000 i.e the color black.

Here's the result:
Trans-vessel

'ffmpeg' and 'imagemagick' are some really awesome tools. :happy:

Gif has not transparency in a smooth way, only as 1/0 like a shaped color, it is also not an optimal format in size terms and quality... you should try other "animated image formats" to see if they works better, like OGM ? APNG ? svg's/lottie can be included and animated too, animated webp formats , AVIF, MNG / FLIF (not sure if these ones are supported in EFL).

Another option is to render the animation/video set in multiple .png files (mencoder can do easly that), and then inserting them as an animated image in the EFL interface, this is the code to reach that:

description {
    image {
        normal: "spinner.png";
        tween: "spinning_01.png";
        tween: "spinning_02.png";
        tween: "spinning_03.png";

using the "external" feature you may use emotion to play videos on the edje interfaces, but not sure about how stable or performant is this... I would point to the tween feature for this case

I should finish my edc guide documentation :slight_smile:

Instead of publishing the .edj files, publish the directories of your edjes with their images and edc files, there's multiple reasons for that:

  • edj is binary, taking much more size, not being well managed by git, requiring to commit a full binary result each time, making the git repo huge
  • there's a loss of quality everytime you decompress an .edj file, original sources must always be used when modifying an edje
  • commits / changes are gradual and can be easily seen as "diffs" of the edc, very small sized, can be commented, viewed, edited from the web, etc...
  • if you are good in git, you can create a CI that will automatically generate .edj files from your releases :applause: , im actually doing that to automate the releases of the super audio player im finishing to make :smiling_face_with_sunglasses:

I think that is the best way to go, where personally I'd look for going the .svg way.
But ... as I noted: I wasn't intending to create animated wallpapers just sharing my thoughts about them. :smiley:

That was actually quite puzzling when I first came across that ..... thinking that somehow the 'be' had got lost. :rofl2:

If that's the one on github (i.e 5_BG) then ... Yes, I have. That's the one I deemed "overdone".
I'm a great lover of "Less is More" and I don't mean the command-line version here. :innocent:
