Any support to get duration of gif file about gifu

[fouadkada]

i am trying to use the project to display a gif as a splash screen, it would be nice to get the duration of the animation to start a new viewcontroller after a specific duration

[kaishin]

No it is not. It could be something that the API exposes though. What you need that info for?

[kaishin]

Yes, that is not unreasonable.

i am following the same approach on the android version of my project and for that i am using this project https://github.com/koral--/android-gif-drawable
and that project exposes this set of APIs

stop() - stops the animation, can be called from any thread
start() - starts the animation, can be called from any thread
isRunning() - returns whether animation is currently running or not
reset() - rewinds the animation, does not restart stopped one
setSpeed(float factor) - sets new animation speed factor, eg. passing 2.0f will double the animation speed
seekTo(int position) - seeks animation (within current loop) to given position (in milliseconds)
getDuration() - returns duration of one loop of the animation
getCurrentPosition()

they also expose an event listener that is triggered on animation completion which can be used to start a new controller
this is the equivalent in android

gifDrawable.addAnimationListener(new AnimationListener() {
                @Override
                public void onAnimationCompleted() {
                    Log.d(TAG, "splash screen animation complete...starting activity");
                    if (gifDrawable.canPause()) {
                        gifDrawable.pause();
                    }
                    Intent i = new Intent(SplashScreen.this, MainActivity.class);
                    startActivity(i);
                }
            });

it would be nice to have something similar

Thanks for sharing this @fouadkada. I had thought about adding some of these and this is a good reference. I'd happily welcome PRs as well.

+1 on this as well. I'm working in a project that is dependent on showing a new view controller when the gif image has finished. It would be great for this to be dynamic instead having to manually find out the duration of the gif file.

This can be done using GIFAnimatable.gifLoopDuration starting https://github.com/kaishin/Gifu/releases/tag/v3.0.0 😉 It used to be there before but didn't work properly if called immediately after calling any of the animate() functions.
