• Cannot play video in TextureView Android

  26 octobre 2014, par Billda

  I have a problem with playing video on some devices. I am using textureview with mediaplayer, every methods of SurfaceTextureView are called but when I just call mediaPlayer.start(), immediately the listener with completition of playing is called. In log is this error :

  E/MediaPlayer﹕ error (1, -2147483648)

  When I list log from all applications, I can see some errors and I dont know if it is somehow related http://pastebin.com/rRxxQgdJ

  This log is from CyanogenMod with Android 4.3.1 but on some other devices like Samsung Galaxy S3 mini this error is happening.

  On my Nexus 4 everything works fine. I’ve tried convert that video with mp4 codec for android H.264 and even with ffmpeg but the result is still the same. I am using TextureVideoView implementation from here :
  https://github.com/dmytrodanylyk/video-crop/blob/master/library/src/com/dd/crop/TextureVideoView.java

  Thanks for any advice

• How to make video (of any format) compatible to play in android's default player ?

  24 janvier 2014, par Aarti

  I want to play video urls from server in device's video player,but unable to play all videos
  Testing on HTC Desire (4.1.1), Panasonic (4.1.3), Samsung G S2(2.3.6).

  I've already gone through following links

  Sorry, this video cannot be played - streaming mp4 to android and
  How to Play Streaming Audio/Video from a url ?
  but did not found working solution.

  I understand few imp things from above,

  1. Video must be baseline H264 encoded for playing successfully on all devices
  2. For encoding any kind of video to H264, we need to integret ffmpeg

  My questions are,

  1. How exactly I can convert any format of video to H264 baseline support ? Examples are appreciated.
  2. Is there any alternate way for FFMPEG ?
  3. How can I check if video is baseline H.264 ?

  I have tried playing videos with both Intent ACTION_VIEW & MediaController, result was same for both.

  Its very urgent. Any kind of help or hint appreciated. Thank You.

• 3 seconds latency while streaming with Wowza Server

  18 mai 2015, par kaizen_labs

  I’m trying to develop a live streaming application with RTSP protocol.

  On the PC with the Wowza Server, I execute the following command :

  Code :

  ffmpeg -f dshow -i video="Name_Of_My_Cam":audio="Name_Of_My_Microphone" -vcodec
  
  h263p -f rtsp -muxdelay 0.1 rtsp://:1935/live/test

  And I’m trying to play this stream on a VideoView on my Samsung Galaxy Note 3 Lite. Here is the code :

  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
      VideoView vv = (VideoView) findViewById(R.id.videoView);
  
      // Receive RTSP video from Wowza Server
  
      vv.setVideoURI(Uri.parse("rtsp://:1935/live/test"));
  
      vv.requestFocus();
  
      vv.start();
  
  }

  I managed to read the video and the sound but it makes 3 secondes (or more...) to start and I keep this delay during all the streaming. It is very annoying because I want to develop a call session.

  Does anybody know how to reduce this delay ? Is it a Wowza issue ?
