I have a MPMoviePlayerController instance in my iOS app, that plays a local file in fullscreen mode. This all works fine, but now I want to add a custom button to the window for changing the playback speed. We support both iPhone and iPad in all orientations.
I know how to set the playback speed from code (using setCurrentPlaybackRate), but I need to let the user do it while watching the video, which means adding some kind of button to the playback screen next to the existing buttons, e.g. next to "play", "pause", or in the top bar.
By looking on StackOverflow I have found various replies for questions similar but not quite the same, some saying it cannot be done in fullscreen, some saying it can be done (but is very complex) by creating some kind of overlay, effectively replacing the entire overlay with a custom one.
Although, I have yet to find any code examples (apart from a few snippets without context), getting-started style tutorial or similar for this, so any pointers to example code would be greatly appreciated.
maybe this Apple example could help you

I want to play video streaming using MobileVLCKit in fullscreen mode.
How can I do this?
Please share code if possible (swift)..
I just saw that my previous answer on the old thread was massively downvoted back then. It's still true though. MVK renders in a simple UIView, so it is the obligation of the client app to implement the view handling, be it a tiny one or one filling the screen.
Note that there is sample code available on how to integrate MVK here: https://code.videolan.org/videolan/VLCKit/
I am learning to develop iphone apps and I have a simple question.
I am making a really simple app which allows the user to set the volume of the device on the settings screen using a slider instead of the volume buttons.
It may be quite obvious for experienced developers but I just can't find the answer I am looking for.
My question is:
How can I make this slider?
Basically I want to do this (image: https://www.dropbox.com/s/b81bzdwyrab0ha7/slider.png?dl=0):
I used to think that I could use a regular UISlider but some documentation says that I need to use something called a MPVolumeView. The problem is that I can´t find a good tutorial that tells how to use this explicity.
I found this link on the apple documentation but I dont understand how this works. – http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPVolumeView_Class/Reference/Reference.html
And the description says: Use a volume view to present the user with a slider control for setting the system audio output volume, and a button for choosing the audio output route. When first displayed, the slider’s position reflects the current system audio output volume. As the user drags the slider, the changes update the volume. If the user presses the device volume buttons while sound is playing, the slider moves to reflect the new volume.
This is exactly what I want but I dont understand the example it gives. If you could please tell me how t make this slider work, even if it is on a new one-view project, I would really appreciate it.
Also I am aware that this method also creates an airPlay button next to the volume slider. Is there a way to delete this button? (My app is a simple productivity app so I only want the slider, not the airplay button).
I also understand that this will not work on the simulator. How am I supposed to know that this will work without having to test it on an actual device (I am not registered as a developer yet)?
Plus, I only know objective-c, not swift. If you could please restrain from using swift in your answers I would apreaciate.
Thank you so much for your help.
PD: English is not my first language. Sorry for any mistakes I made.
The MPVolumeView class is designed to let you do exactly this. It's in MediaPlayer.framework, so add that to your app to make things build correctly.
You create it and make it visible the way you instantiate any other subclass of UIView, which you probably know by now.
You disable the routing button by setting the "showsRoutingButton" property to false.
"How am I supposed to know that this will work without having to test it on an actual device?"
By seeing that it's been there since iOS 2.0, and is used in countless apps?
The process to writing such a slider is incredibly simple, look into UISlider(https://developer.apple.com/library/ios/documentation/UIKit/Reference/UISlider_Class/) and then use the float value from the slider to set the volume.
If you do not want to write your own slider, look on GitHub(github.com) for controls that do this for you. After doing a quick search, I found this UISlidersubclass that adjusts volume.
I am working with a sample application like vine. My requirement is that I have to create a 'ghost' filter for video as in vine.
Actual requirement is
-Record a video on long press on the view
-On pause of record, I need to show the last frame of the recorded video above my view. Please see the expected working here
I have checked PBJVision library and found this feature working. But I need to implement this feature separately in my application.
While analysing the code, I found that this can be achieved using Open GLES. I have tried using a GLKView but it just shows a dark shade instead of image frame. Since I am new in this area, please help me.
I have an app and would like to have a video loop in the background of my initial view. It will serve as my home screen and menu and will have buttons overlaying on top of it. I have looked around but can't seem to find a guide or tutorial on this.
Take a look at MPMoviePlayerController for what is probably the most approachable way to attack the video idea.
MPMoviePlayerController will very quickly let you present a fullscreen interface, but will require a bit more work to use it "in-line" which is what you are describing.
Otherwise you'll find yourself wandering down the AVAsset path, which will allow far more control over what is happening, but will require quite a bit more code to configure.
As far as 3rd party options go, using the excellent GPUImage will allow you to throw a video at a view quite seamlessly and with very little code written on your part (the "SimpleVideoFileFilter" project in the examples can show you the way). But since you are merely displaying a video, this would be a significant amount of bloat for your project.
Bigger picture, using Animations instead of a movie has lots of appeal, for the performance, battery life, and general responsiveness of your app reasons stated by others.
I want to remove/hide the full screen button from MPMoviePlayerController standard controls as full screen mode is creating lot of problems and also not a requirement of my app.I just want the play,stop,forward,reverse controls. Can anybody help me?
There's no standard way to do this. Here are your options.
You could set the MPMoviePlayerController's controlStyle to None and create your own custom controls. Cons: this is a lot of work.
You could use the NSNotificationCenter to intercept the MPMoviePlayerWillEnterFullscreenNotification and immediately set fullScreen mode to NO. Cons: based on the iOS version of the user, this may cause a flicker or some glitchy effect.
You could go through the MPMoviePlayerController view's subviews until you get to a MPInlineTransportControls view which contains the controls, the slider and the play/pause button and the full screen button which are all of class MPTransportButton. Find that one and you can hide it or remove it from its superview. Cons: as of right now this passes app store reviews and works perfectly on all currently supported iOS versions. But this could change at any time. If Apple decides to redo their default video player you may end up with non working code.
