[Deepa M]

Hi all,
Is it possible to live stream the video frm videoplayer  (which plays
recorded video )  in android?

Thanks and Regards

Deepa M

Re: [android-developers] Video streaming plus UI control update thread

[Bradley O'Hearne]

Piren, 

Thanks for taking the time to respond. I was able to figure out the problem…but 
I can confirm that Thread with sleep is bad. Handler is the right approach — I 
had something (not obvious) several layers deep in the call chain which was 
causing the problem. 

Thanks again for your help. 

Cheers, 

Brad

 Since i see no reason why it would affect your playback like so, i suggest 
 you just profile your app and see exactly what calls cause the slowdown.

  Hey there, 
  
  I hope everyone’s week is off to a good start! 
  
  I have a pretty simple use case: I am playing video streamed across the 
  network in an app, and I need to update two SeekBars every second, one 
  which tracks the video’s timecode while playing, and the other which tracks 
  the device volume. Simple enough, gun up a background thread, and update 
  both every second (given that to my knowledge, I can’t have the system call 
  a listener specific to either of those functions. In a nutshell, the video 
  streams just fine when this control-updating thread isn’t running, but when 
  it is running, the video is so chunky and slow, and audio garbled, that it 
  isn’t watchable. 
  
  First, the video display is accomplished using a TextureView in combination 
  with a MediaPlayer (the reason is that the TextureView allows scrolling / 
  movement, SurfaceView does not). Second, I have tried a couple of different 
  approaches for the background thread: 
  
  a) I have tried a Runnable in a new Thread which updates the SeekBar 
  controls inside of a runOnUIThread — this keeps a looping background thread 
  and updates the controls on the UI thread, as such: 
  
  new Thread(new ManagementRunnable()).start(); 
  ... 
  public class ManagementRunnable implements Runnable 
  { 
 public void run() 
 { 
 try 
 { 
 updateControlState(); 
  Thread.sleep(1000); 
 } 
 catch (Exception ex) 
 { 
 ex.printStackTrace(); 
 } 
 } 
  } 
  ... 
  public void updateControlState() 
  { 
runOnUiThread(new Runnable() 
{ 
 public void run() 
 { 
  // update the timecode SeekBar 
  ... 
 // update the volume SeekBar 
  ... 
 } 
  } 
  } 
  
  b) I have also tried using a Handler, where it runs on the UI thread, as 
  such: 
  
  new Handler().post(new ManagementRunnable()); 
  ... 
  public class ManagementRunnable implements Runnable 
  { 
 public void run() 
 { 
 try 
 { 
 updateControlState(); 
 handler.postDelayed(this, 1000); 
 } 
 catch (Exception ex) 
 { 
 ex.printStackTrace(); 
 } 
 } 
  } 
  
  public void updateControlState() 
  { 
  // update the timecode SeekBar 
  ... 
 // update the volume SeekBar 
  ... 
  } 
  
  The problem is, the result is the same regardless of which approach is 
  taken — the video is unwatchable. I have tested this on a Samsung Galaxy S2 
  Skyrocket, and in the simulator. I’ve Googled this a fair amount, and it 
  appears that the approaches above are generally the recommended approach. 
  While video decoding and playing isn’t exactly a cheap operation, I’m a 
  little surprised that accommodating a once-per-second update brought the 
  app to its knees, given nothing else taking place in the app. 
  
  If anyone has any insight, I would really appreciate

I test it on Android 2.2.2 (HTC quiet brilliant) and all works fine. When I

But when I test it on Android 4.0.4 (Galaxy S2) Server create file and 
record data from stream to file but not play in VLC (and other players too) 
and give me error 

mp4 error: MP4 plugin discarded (no moov,foov,moof box)
 avcodec error: Could not open �codec demux error: Specified event object 
 handle is invalid
 ps error: cannot peek
 main error: no suitable demux module for `file/:///C:/1345461283455.mp4'


I also try to upload this file to youtube, but after upload youtube give me 
error like file format is unsupported.


But Android 4.0.4 (Galaxy S2) succesfully create and then play file when I 
save it on phone memory (not stream to server)

I think problem maybe on server side, or something changed on android 4.0.4.

Please, help me.

I test it on Android 2.2.2 (HTC quiet brilliant) and all works fine. When I 
press start button Server create file and record data from stream to 
file. After this file is normally play in VLC player and etc.


But when I test it on Android 4.0.4 (Galaxy S2) Server create file and 
record data from stream to file but not play in VLC (and other players too) 
and give me error 

mp4 error: MP4 plugin discarded (no moov,foov,moof box)
avcodec error: Could not open �codec demux error: Specified event object 
handle is invalid
ps error: cannot peek
main error: no suitable demux module for `file/:///C:/1345461283455.mp4'

I also try to upload this file to youtube, but after upload youtube give me 
error like file format is unsupported.


But Android 4.0.4 (Galaxy S2) succesfully create and then play file when I 
save it on phone memory (not stream to server)

I think problem maybe on server side, or something changed on android 4.0.4.

Please, help me.
Thanks in advance.

[android-developers] video streaming UDP to android

[Leonardo]

Hi,

I have an application that makes video stream to an internal network (192 
...) 
and I need to broadcast to all connected devices in the network. Since the 
players
have found to only get android http stream, so does anyone know if there is 
any
player who receives the video stream in udp protocol?

thankful!

[android-developers] Video streaming from android mobile phone to a remote computer

[Christina Loop]

Hello everyone,

The problem I have is in the implementation of a video streaming
application. What I need to do is to stream live what I record with
the androids' camera, to a remote computer. I managed to establish a
connection between the mobile phone and the computer, but I do not
know how to send the video.

 I searched through forums, and I found out that in order to send a
streaming video you have you use the ParcelFileDescriptor. So I
created an instance of MediaRecorder with encoding H263 and .mp4 file
format, I created a Socket and then I created a new
ParcelFileDescriptor connecting it with the socket. If that is correct
then the android application that I created is functional.

 What I don't know now is what to do at the side of the computer in
order to receive and view the streaming video. I tried using JMF, but
it doesn't support .mp4 video files. What do you suggest me to do? Or
where to look in order to find a solution?

Thank you in advance,
Christina

[android-developers] Video streaming from Android

[RFuente]

Hi everyone.

I'm trying to do live-record streaming from an Android phone and got
stuck in a problem quite difficult to tackle. After messing around
with an hex editor, I've found that MediaRecorder class places the
moov atom at the end of the MP4 file. As this atom is necessary to
work with the MP4 file and I'm sending the stream while recording, I'm
'blind' at the server side until the transfer is completed.

The idea is to start playing/coding/whatever the file in the server
side in real time but the received file only contains mdat bytes at
this moment. Has anyone faced a similar problem? Do you have any idea
if this task can be accomplished?

Thanks beforehand.

[android-developers] video streaming in android

is it anyway to obtain raw stream of data that can be given to
encoder?

[android-developers] Video streaming, omx problem

[Faboom]

Hello,
I want to stream video via sdp.
The stream url is set to a MediaPlayer as described in the api sample.
Most of the times it is working fine.
Sometimes, however, i get a black or green screen and the log says:

E/QCOmxcore(   51): OMX.qcom.video.decoder.avc Instance already
exists, return OMX_ErrorInsufficientResources

There isnt even an error callback to notify the user or initiate
appropriate measures.
I think the only way to fix this is to reboot the device, but i hope
there is a more convenient ;) method ..
Cheers,

[android-developers] Video Streaming

[mobilek...@googlemail.com]

Hi, I'm trying to stream a video from an HTTP server to my client. In
order to play it I fire up an action_view intent by providing to it
the uri of the media. The client opens up a new browser window, and
then redirects to the youtube player as expected. However, after a
couple of seconds it throws a 'Cannot play video' error. Has anyone
come across this before? Thanks

[android-developers] Video streaming error in SDK 1.5

[Jason Proctor]

the moov and mdat atoms should already be there, (IIRC) they are 
required for a well-formed movie file.

the moov atom provides metadata for the movie, and the mdat atom 
provides the actual content. however, if the file is being streamed, 
the client needs to know the metadata before the actual content 
arrives, therefore the moov atom must be ahead of the mdat atom. 
can't stream the stuff in the mdat if you don't know what format it 
is.

there are some tools around to swap the atom order so that a file is 
streamable, but doing it yourself is reasonably straightforward. one 
way is to go through the file remembering the positions and sizes of 
the atoms, then reorder the list, and write out a new copy of the 
file with everything in the right place. check the Qt file format 
docs.

i will have to do this too at some point but i don't know whether at 
some point is good enough for your schedule.
