How can i assign whats going to happen when you press fastforward or rewind?
I have a couple of youtube videos that i want to play after eachother. Therefor i need to assign these 2 buttons in the MPMoviePlayerController. i've tried to search on this subject, but have not found anything yet.
The other thing is how can i check wether a song is done, cause i want it to automatic to go forward then.
How can i do this?

I already tried the way using currentPosition and yeah, i know what type of value does it return...
I wanted to use that return value as the position of music and when i resume the music, then the music continues at that position. But how do i make the music get started from that position?
Like, can i use the currentPosition method as an argument?
For example like "player.controls.play(currentPosition)" but i don't think that play() method gets any arguments...
To sum up the above, I'm using WMPLib and i wanna make music paused when i click button and also resume when i click another button.
is there any good solution maybe?
I'm working on an iOS movie editor project. For this editor, i use MPMoviePlayer to show the video file selected by the user.
I use custom controls, and I have a UISlider that enables the user to move the player's currentTime position. When the user touches the slider, movie is paused and its currentTime changes along with the UISlider's value.
Everything works perfectly, but now i need to let the user hear the sound at this currentTime position.
For those who know iMovie, when you move your mouse over a movie event, you see the image and hear the sound at this position, and that's what i'd like in my editor.
I've tried to call player's play method with à NSTimer to stop after 0.2 seconds, but the result is kind of messy.
Has anyone already achieved to do something like this ?
Thanks !
Best regards.
Seeking takes time; that's why you've ended up using a timer. The real problem here is that MPMoviePlayerController, while convenient because it gives you controls, is a blunt instrument; it's just a massive simplified convenience built on top of AVFoundation. But you don't need the built-in controls, so I would suggest throwing away your entire implementation and getting down to the real stuff, using AVFoundation instead (AVPlayer etc). Now you have a coherent way to seek and get a notification when the seek has completed (seekToTime:completionHandler:), so you'll be able to start playing as soon as possible. Plus, AVFoundation is the level where you'll be doing all your "editing" anyway.
I have a situation where I'd like to play 2 video clips back to back using an MPMoviePlayerViewController displayed using presentMoviePlayerViewControllerAnimated.
The problem is that the modal view automatically closes itself as soon as the first movie is complete.
Has anyone found a way to do this?
Three options:
You may use MPMoviePlayerController and start the playback of the 2nd (Nth) item after the previous is complete. This however will introduce a small gap between the videos cause by identification and pre buffering of the content.
You may use AVQueuePlayer; AVQueuePlayer is a subclass of AVPlayer you use to play a number of items in sequence. See its reference for more.
You may use AVComposition for at runtime composing one video out of the two (or N) you need to play back. Note, this works only on locally stored videos and not on remote (streaming or progressive download). Then use AVPlayer for the playback.
It's not possible. If the video assets are in local file system, consider AVComposition.
this is my first question, but I've readed StackOverflow for years.
Well the thing is that I must concatenate a set of videos (MP4) in a particular order, and the last one must loop continuously. Okay, let's try AVFoundation.
I've defined all the elements such as AVComposition, AVURLAsset and AVPlayerItem. Then I build the AVPlayer and the AVPlayerLayer. Everything is okay and the videos are played in the correct order but... (and here comes the problem)
I can note a tiny flick when the AVPlayer passes from one video to the next one. I can ignore that one, but when AVPlayer reaches AVPlayerItem's end, and the selector is called for AVPlayerItemDidPlayToEndTimeNotification, I use seekToTime to move the reading head to the correct and then play it again. Works fine, but a GREAT flick is repeated when using seekToTime and playing again. I cannot allow that.
Does anybody know how to repeat the last asset on AVPlayerItem continuously and without flicks?
Thank you all.
Absolutely stupid,
Friends, when making video manipulation apps be sure that the videos don't have annoying black frames. That was the root of all problems. [AVPlayer seekToTime:] works perfectly.
Thanks for your time and patience
I have a problem not sure how to solve this. Hmm I am developing a game, a multi touch game, I already can make everything working fine, except a small issue that I want to show messages on the playing screen, each time the player makes actions. like his finger moves right the message says : "this finger moving right" nicely at the bottom of the screen, then if the finger move left, then it says the his finger moves left... something like that, can anyone show me how. I am using Cocos2D , it shall be much easier in Cocoa.
Thanks a alot for any help.
You'll probably need to be more specific with your question, but for now, here's a general answer:
Handling touch events on the iPhone and Handling touch ("trackpad") events on the Mac.
You'll receive and process the events per the above, then you'll display the results somehow. For testing, you'll probably just want to log the results to the console. For the final version, you might have a label or even a custom view that draws the "instruction" in some fancier way. If the latter is the case, you'll want to read up on custom views and drawing for whichever platform you're using (or both).
