playback

问题 I want to work on Adaptive playback the new feature in android 4.4. But I am confused how will I test the same. I will be using HTTPS links for video. Has anyone worked on it and can help how did they achieve it. Thanks in Advance. 回答1: CTS has adaptive playback as one of its tests: AdaptivePlaybackTest.java. You should be able to reference AdaptivePlaybackTest.java for ideas on how to implement the test in your own software. Otherwise, compiling the CtsMediaTestCases package in CTS should

问题 When I click the play button, it just goes to the end of the timeline. But if you drag the ticker somewhere in the middle (or anywhere really) it plays the video. So why won't it play initially? It works in every other browser other than firefox. Im using Firefox 17 I appreciate the help. Thanks. heres the link http://www.lonestarveincenter.com/ 回答1: Sorry for the necromancy but I found the answer to this problem.

问题 So I have dynamic tableview and each row have play image. If I select the row image will change to pause icon. But what if I select another row, I need the image on previously selected row to have play icon again. How to handle such functionality? All I have is: class ViewController: UIViewController { var stations = [ (stationIcon: "rr_icon", stationName: "Radio1", urlString: "http://.._320", isPlaying: false), (stationIcon: "mm_icon", stationName: "Record2", urlString: "http://../_320",

问题 I have a storm in my game, and so I've made an ambient audio file which slowly grows into a storm and rain fades in, which then becomes a loopable storm audio file. Here is how I've done it: // Play intro clip and merge into main loop var introTime = stormIntro.length; AudioSource.PlayClipAtPoint( stormIntro, Vector3.zero, 0.7 ); Invoke( "StormMusic", introTime ); The way I'm currently trying to do it is get the length of the storm_intro audio clip, play the clip, and then invoke storm_loop

问题 I would like to change song on my MediaElent from track1.mp3 to track2.mp3. And here is the code: MyMediaElement.Stop(); Uri u = new Uri("track2.mp3", UriKind.Relative); MyMediaElement.Source=u; MyMediaElement.Play(); The MediaElement change the source but just won't start. What could possibly be wrong with this code? 回答1: Try setting MyMediaElement.AutoPlay to true, as soon as the source changes it should play. You could also investigate using the MediaElement.SetSource() method which takes

问题 I just wondering if anyone can explain to me how I would go about recording audio, modifying it (pitch?) and playing it back to the user on iPhone. I'm not asking for someone to do this for me, just a few hints on how I should go about it. looking through the docs it seems like I should be using AVAudioSession , AVAudioRecorder and AVAudioPlayer ( AVFoundation.Framework ) for the recording playing parts. Or should I be using the CoreAudio.Framework ? and then there is the question regarding

问题 I wanted to create a simple gui with a play and stop button to play an mp3 file in python. I created a very simple gui using Tkinter that consists of 2 buttons (stop and play). I created a function that does the following: def playsound () : sound = pyglet.media.load('music.mp3') sound.play() pyglet.app.run() I added that function as a command to the button play. I also made a different function to stop music: def stopsound (): pyglet.app.exit I added this function as a command to the second

问题 So, I know that this has been done with a few Android apps before, but I cannot for the life of me figure out how, since it's not currently possible through the API. How does one adjust the playback rate of a sound played through MediaPlayer; either with or without adjusting the pitch is fine for now, though the latter is definitely preferred. If someone can point me in the direction of an open source app that I can use as guidance, that would also be fine. Thanks in advance. 回答1: Looks like

问题 I am developing an application where I need to start the default music app and play all the songs. I have tried a number of approaches, but nothing seems to work. Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage( "com.android.music.MediaPlaybackActivityStarter"); startActivity( LaunchIntent ); and Intent intent = new Intent(); ComponentName comp = new ComponentName("com.android.music", "com.android.music.MediaPlaybackActivity"); intent.setComponent(comp); intent.setAction

问题 I've got an android app that listens to music broadcasts. It receives track change notifications using the following ApplicationManifest.xml (snippet): <receiver android:name=".music.AndroidMusicBroadcastReceiver"> <intent-filter> <action android:name="com.android.music.metachanged"/> <action android:name="com.android.music.playbackcomplete"/> <action android:name="com.android.music.playstatechanged"/> <action android:name="com.htc.music.metachanged"/> <action android:name="com.htc.music
