A screensaver for Mac OSX / macOS that plays animated GIFs and APNGs

animatedgif's Issues

Screensaver is misaligned under the menu bar when run in background

If you run the screensaver in the background, it starts just below the menu bar, and you can see the other desktop background above it, behind the menu bar. If you have a screensaver that's the same size as the display, the bottom is cut off at the bottom.

Generate mipmaps in Metal Render

The Metal Render not creates mipmaps so that minimised texture still look good.

[MacOS 10.14] Bug in drawInRect of NSImage let preview window stay black

I saw another bug of macOS 10.14 in the method drawInRect of NSImage. When method is used to draw into the preview window of the preferences panel of screensaver it stays black. This was working until 10.13 .
I tried a workaround with using OpenGL instead to draw into the preview window witch seems to work with 10.14 but I remember using OpenGL for the preview window with an older version of OSX leads to crashing. But I can't remember witch version it was (Mavericks or El Capitan ?). I need more tests before making an official release with OpenGL in preview window, but I will already submit the source code changes.

Handle variable delay times between frames

A GIF file can have a unique delay time for each frame, but AnimatedGif only uses the one of the first frame as static value.

Add Japanese localization

Since I just start learning Japanese will be mostly a google translation witch is probably very bad.
So tagging it as enhancement is maybe a not so good idea and I should tag it as impairment. ;-)

Feature Request: GIF Overflow

Feature to allow gif to overflow screen creating a nice full screen effect

From this:

To this:

Handle GIF's that have no delay time in frame 0

AnimatedGif only uses a static delay time of first frame and can not handle variable delay times (see #26).

Unfortunately I saw some rare GIF files, where the first frame had no delay time at all (delay time = 0ms -> infinity fps). In some cases often the later frames include a valid delay time.

But since AnimatedGif only supports a static delay time the GIF was running way too fast.

Add support for Animated Portable Network Graphics (APNG)

Add support for Animated Portable Network Graphics (APNG) witch is a more modern graphics format for animated images. Since it is very similar to GIF and supported by NSBitmapImageRep(there a only small differences) it should be easy to implement.

Optimise 3x3 tiles rendering

The 3x3 tiles rendering creates a new texture for each of the 9 tiles. It would be better to create only 1 tile and map it to 9 quads.

Excessive CPU usage while connected to an external display

Title says it all, there's excessive CPU usage while connected to an external display
Fans start running at full speed when the screensaver comes on. When there is no external display connected, it is fine.

GIF loads too slow

GIF will look okay when viewed in sys pref. But when previewed or seen as screensaver the gif runs slow
Tried running at 30 fps with manual override setting.

[10.13.4] Support multiple screens in background mode

Right now the background mode only supports the mainScreen ( https://github.com/Waitsnake/AnimatedGif/blob/master/AnimatedGif/AnimatedGifView.m#L113 ). It would be nice to support other connected screens as well.

It might be a stretch, but it would also be great to be able to pick what gif will be shown in what screen.

Feature Request: GIF files over 30 fps

Please allow to load upto 60fps GIFs

value from gif will allow over 30fps but manual frame rate is limited to 30

Feature request: Pixel perfect rendering

When low resolution pixel art images are stretched, they are rendered blurry, rather than sharp. Pixel art looks much better sharp than blurry.

A workaround is to blow the images up yourself making sure they stay sharp, but I think this may be more taxing on the computer to run.

Cycling through the folder

It would be nice, if you have multiple gifs, if you could set a cycle count to how many cycles each gif goes through before loading up another random gif from the file or have the ability to change the time between cycling.

Also on multi monitor support, if there are enough gifs in the folder, have the ability to disable duplicates so no 2 screens show the same gif

Thanks for your work this thing is great! :)

Run?

How do you setup and run this?
Thanks

Background color doesn't match GIF using color picker.

Support of different frame delay times in GIFs

Even if this feature(different frame delay times in GIFs) is not used very often in most GIF files a GIF can contain different delay times between frames resulting in variable fps values during running.

For the sake of easier implementation and because the method animateOneFrame from the class ScreenSaverView did not support a changing of timerAnimateOneFrame between startAnimation and stopAnimation AnimatedGif until now did not support this feature. It uses an fixed delay time(means a fixed fps) from the first frame of the GIF for the complete animation time.

To support this feature AnimatedGif needs to trigger the needed animation steps within its own controlled timer method.

[10.13.4] black screen in normal screensaver mode

The preview I see in Settings.app looks fine, but when I activate the screensaver, the screen is black.

I've tried 1.3.6 and the 1.3.7-beta. Running 10.13.4, two external displays on a MacBook Pro in clamshell mode.

Slider for timer interval is gray but still selectable

When the single file mode is active the slider for timer interval is gray, but still selectable.

[MacOS 10.14] Bug in NSOpenPanel of Mojave let crash AnimatedGif

On MacOS 10.14 beta 1

It crashes the desktop and screen saver menu.
I opened the project in Xcode and did some deprecation clean up now it stopped the crash but still does not load up due to constant error of missing DYLIB.

Request

Any chance of making the gif random from a folder? Allow for a change every X amount of minutes?

five stars

I love your animatedgif screensaver. great code, it does the job.
I like to use it with http://stormandsky.com/gifs.html
But I also use
http://s.sudre.free.fr/Software/SaveHollywood/about.html
https://pastebin.com/q8Y373zK
https://flixel.com/cinemagraphs/nature/

personally, I do use SaveHollywood with cinemagraphs from flixel,
and a custom launch agent. I have more mp4s, they use less memory,
2% cpu vs 5% for a gif. BUT!
it doesn't truly seamlessly loop. gifs loop a little bit better.
It is harder to tell where they transition, sometimes even impossible because
they will rewind for truly seamless loop.

[Request] Put this screensaver on the App Store

Rather than having this file run by the user from GitHub, there might be more visibility and more trust in using it from the App Store. This way, users can just uninstall via the App Store on macOS rather than additionally downloading a separate file to uninstall the screensaver.

Having trouble running in the background

I'm just installing AnimatedGif, and for some reason it doesn't work in my background mode. I'm not sure if it has to do with macOS High Sierra or if even a version of Xcode I'm using (8.2.1).
I'm following the instructions on the installer and I tried looking through all of the questions before asking. If anyone can help troubleshoot, that'd be awesome.

Frame rate of gif not detected properly

Noticed that for this gif the frame rate is not automatically detected properly (it runs slower than it should)

(also, this should probably say cancel instead of Abbrechen)

Love the project, thanks a lot

Stretch keeping ratio but filling screen completely

Hi, I love AnimatedGif, it works by far the best with super low cpu usage. Awesome work! If I may have a small request, I'd like to see an option for keeping the gif image's ratio but filling the screen completely with some part of the image going outside the screen area. This would make it perfect for me. Thank you!

Multiple Change Timers in Preview Mode

In Preview Mode within the screensaver options and when the config panel is closed an stopAnimation event is fired by ScreenSaverFramework and then an startAnimation event.
startAnimation starts a new change timer, but the old timer was not stopped and so multiple change timer could be running. With multiple open and closing of the config panel this could lead to a very high number of running timers and very short and unpredictable change intervals of the preview form the screensaver. Once I even see [MTKView currentDrawable] crashing due to the high frequency.

This never happen in Normal or Background Mode since in those modes the stopAnimation event is only send before screensaver process closes completely and this will end also a running timer.

Add a version number

Add a version number of the release to preference panel and info.plist (visible version number in finder when selecting screensaver object).

Feature Request: No time between random gif changes

First off thanks for this awesome screensaver. It would be great if we had an option to not have any time between gif changes when a directory is selected.

GIF is zoomed in even if stretch to screen option is disabled

Directory Mode is Greyed Out

Directory Mode is Greyed Out so selecting a directory also doesn't work only single file is allowed

The preview of option "keep image original size" is not realistic

The preview of option "keep image original size" is not realistic since it not scales the image on the small preview window to the size how it would look like if it was on the main screen.

AnimatedGif crashes when a folder is selected that is not empty, but contains no GIF files

AnimatedGif crashes when a folder is selected that is not empty(contains other folders or files of other type than GIF), but contains no GIF files.

After AnimatedGif is restarted it continuous to crash since the folder was already saved into screensaver defaults file.

Review of Japanese GUI

Since I'm still a beginner in Japanese I did't the most translation of Japanese GUI with help of Google. But because Japanese is such a hard language to translate this output is not always useful and needs to be fixed.

High Sierra: Screensaver not visible in System Preferences after "Install for this user only"

When the screensaver is installed in High Sierra 10.13 with the option "Install for this user only" it is not visible or selectable in the Systems Preference panel.

A workaround is to install the screensaver with option "Install for all users of this computer".

after starting screensaver in background mode a second instance of a screensaver will not start

This is a problem or intension of implementation of the ScreenSaverEngine. When running it with parameter "-background" a second instance of a screensaver will not start(e.g. after inactivity of user or moving mouse to an active corner).

I found out that calling the screensaverenginge with parameter "-idlecheck" a second time after the background mode is already running will stop this lock and enable a second screensaver instance afterwards.

This needs to implement in AnimatedGif within the startAnimation method in case the screensaver instance starts first time.

Change behaviour of About Window and Open Files Dialog

Since implementing the workaround for #37 the About Window and Open File Dialog are behaving a bit strange. They opened in foreground but they are still missing the input focus (meaning they are no key windows).

Update the UI of options panel

The UI of options panel became a bit confusing with the last adding of the folder feature.
So the UI needs to be a bit more clearly represented.

Can't disable it

I've tried to do as many tries as possible to disable and seems not to be able to.

Gifs with high fps are lagging when screensaver is in background mode

When ScreenSaverEnginge is started by launchd with is only used for background mode than the animation becomes lagging. In any other mode, like preview window in system preferences or normal screensaver mode there is no lagging. This happens independent of the used render (same for OpenGL and Metal).

[MacOS 10.13.6] saver window

Having downloaded the Animated Gif as screensaver, I now have a "Saver Window" that is always on my screen. Have tried to get rid of it to no success. It interferes with all activities. Can you advise.

Background mode crashes when option "show with clock" is active

Background mode crashes when option "show with clock" is active too.
This issue not affects the normal screensaver mode though.

It always crashes with an "Segmentation fault 11" when ScreenSaverEngine is startet with option "-window" and "show with clock" is active too.

This is an bug of ScreenSaverEngine and even Screensavers that comes with the System are crashing under the same conditions. But since in macOS an normal user don't use the "-window" option (this feature is for developers of screensavers) this bug was hidden and not relevant.

The option "-background" that I used before did not crash with the clock active, but I needed to switch from "-background" to "-window" because of issue #28 .

Sorry this is a "wont fix" for the moment.

Metal support

Since support for OpenGL will running out on macOS in the future AnimatedGif should add support for Metal as secound render API.
On older systems that don't have Metal it should still use OpenGL for drawing, but it should switch to Metal when a system has it.

Wrong alpha blending in Metal Render

The alpha blending of GIF files is not enabled globally for a hole file, but can be individually enabled or disabled for each frame.

The Metal Render at the moment enables alpha blending for a hole file. The OpenGL Render instead enables alpha blending only for each frame as it should be.

The Metal Render needs to be fixed.

screensaver stay white after return from sleep (using background mode)

There is an issue that glview is not working (stay white) after return from sleep when using background mode.

Starting screensaver in background mode is not working after an clean install

I just did a clean install on one of my machines and than I try to start AnimatedGif in background mode, but nothing happens.

I analysed it and the problem is that on a clean install of OSX the folder '/Users/name/Library/LaunchAgents' is not existing.
In the 'LaunchAgents' folder the file 'com.stino.animatedgif.plist' needs to created to start the background mode of the screensaver. But as long as the folder is missing the file will not created and background mode is not working.

Workaround is to create that folder:
1.) Open Terminal
2.) 'cd /Users/name/Library'
3.) 'mkdir LaunchAgents'
4.) Background mode is now working

The intended bugfix of AnimatedGif will be that the screensaver itself will create that folder if the folder is missing.

High Sierra: Wallpaper mode not working

I saw on YT a video that shows that the wallpaper mode is not working in High Sierra.

Since I'm still on El Capitan I can't analyze the problem at the moment.

Possible reasons:

1. I found this forum where the discuss that the LaunchAgent in High Sierra only allows some narrow privileges of the agent file. But I'm not sure if this is really a problem since AnimatedGif don't give any strange file privileges. Anyway it needs to be checked.
   See:
   https://www.apfeltalk.de/community/threads/problem-mit-launchd.521676/

2. I read that the directory of the screensaver engine has moved! This is definitely a problem of AnimatedGif since the path is used in the launchd script that AnimatedGif creates.
   macOS 10.12 and earlier: /System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine
   macOS 10.13: /System/Library/CoreServices/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine
   See:
   https://iscreensaver.com/help/notes/high_sierra/high_sierra.shtml

3. The command-line parameters to ScreenSaverEngine are broken in 10.13 (Submitted as RDAR 34481351). AnimatedGif can not fix the ScreenSaverEngine.
