由 廉价感情. 提交于 2019-12-06 09:00:39
问题 Is there a way to play audio obtained from MediaStore through the use of the MediaPLayer, Or am I going in the completely wrong direction? I've looked and MediaStore.Audio so far but nothing is really helping me. I just need to know if I'm on the right track 回答1: First, I assume you have basic knowledge of querying a ContentProvider and working with Cursors. If you dont, I suggest you research it here Once you have a basic knowledge of how to use a ContentProvider, query the URI MediaStore

MediaPlayer making APP not responding

由 a 夏天 提交于 2019-12-06 07:43:37
I have an activity that's using a MediaPlayer to play video content. The activity simulates a TV device by playing different HLS video streams on key up/down presses. After watching some video for a longer time (approx. > 15 mins), when I press any key the APP is not responding and is getting to a Force Close screen. Here's what I'm doing on every key event up/down: //I'm creating the media player object only once, after every channel switch i do: if(mMediaPlayer.isPlaying()) { mMediaPlayer.stop(); mMediaPlayer.reset(); } try { mMediaPlayer.setDataSource(app.channels.get(current_index)

ffmpeg av_seek_frame with AVSEEK_FLAG_ANY causes grey screen

由 有些话、适合烂在心里 提交于 2019-12-06 07:36:35
问题 Problem: omxplayer's source code calls the ffmpeg av_seek_frame() method using the AVSEEK_FLAG_BACKWARD flag. Although not 100% sure, I believe this seeks to the closest i-frame. Instead, I want to seek to exact locations, so I modified the source code such that the av_seek_frame() method now uses the AVSEEK_FLAG_ANY flag. Now, when the movie loads, I get a grey screen, generally for 1 second, during which I can hear the audio. I have tried this on multiple computers (I am actually

Gapless Playback with android MediaPlayer

由 守給你的承諾、 提交于 2019-12-06 06:37:50
问题 I'm trying to repeatedly play a audio continuously, without any gap. I've tried, mediaplayer.setLooping(true); But it gives a gap between repeat time. And tried this, mediaplayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { mediaplayer.start(); } }); It gives a gap also. I've tried with different audio format. But neither way worked for me. Is there any other way in android? 回答1: When a playback finishes, the player

Add Custom Controls to MoviePlayer in iPhone 3.0 SDK

由 时光总嘲笑我的痴心妄想 提交于 2019-12-06 04:58:12
I'd like to add custom controls to the mediaPlayer control view much as this asker: Add Custom Controls to MoviePlayer However, the solution posted in the above question is depreciated in 3.0. Does anyone know of a way to do this with the new SDK? So far I have added an overlayView to the moviePlayer view and can display my own controls on touch, but I can't seem to pass the touch on to the moviePlayer view to get it to display the native controls. I've been using touchesBegan and touchesEnded to no avail. Any help is appreciated. look at this sample project http://developer.apple.com/iphone

How to set up Streaming audio with MediaExtractor and MediaCodec?

由 旧巷老猫 提交于 2019-12-06 03:51:15
问题 I am trying to stream incoming AMR_NB. I can't use MediaPlayer directly because it requires a seekable file. I would like to use MediaCodec, but to use MediaCodec I need (I think... please correct me!) MediaExtractor to give me things like the presentationTime. Is that true? Can I use MediaCodec without MediaExtractor? MediaExtractor seems to require seekable files. The documentation only specifically says so for one of the setDataSource operations but when I tried to use any of the others it
