Hello,

I'm having problems with audio/video synchronization. I debugged it in multiple ways and I still can't pinpoint the problem.

First of all I want to mention that the demo application (spydroid) also has the delay between audio and video, i.e. the video is about 1.2seconds late. The problem appears both when using spydroid as a RTSP server or when using the library to stream to a wowza server and then connect with a player to the wowza stream.

AFAICT the packets sent over the rtcp protocol should solve any sync problems. The packets are sent by the phone and received by the player (I tried with vlc and a flash player). It would help me a lot if you game me some debugging ideas or if you could tell me if it works on your end.

I want to also mention that I tested on a Nexus 4 and a Samsung Galaxy S3.

Thank you

I tried encodeWithMediaCodecMethod2 in HTC M8 device,
but it failed when I click recording, and I can not find the reason.

I want to capture an image from the camera while streaming is running. How can I do it with libstreaming?

Video stream is always rotated by 90 degrees even with using of MediaCodec API (I know that it is impossible to set correct rotation with MediaRecorder API). Is there any way to rotate it?

Hi,
first of all i'd like to say that your library is awesome and helped me a lot. Actually this is not really an issue but since Android 4 you can provide a SurfaceTexture instead of a SurfaceView as Preview. A big advantage of this method is that you don't have to add a SurfaceTexture to an activity to be a valid preview. I tried that by just replacing every call to setSurfaceView by setSurfaceTexture and it works perfectly on my Nexus 4. I'm actually not sure wether this is already supported by your library as i did not review the complete code. Just thought in case you don't know this might be interesting.

Best

I have done some research and it seems to be a problematic issue. I have not found a clear answer.

Thanks in advance.

I am having issues streaming audio and video with the MediaRecorder option, MediaCodec works fine. The issue i see is that both AudioStream and VideoStream try to open and start media recorder. How would that work since only one instance of Media recorder can work at one time.

.setAudioEncoder(SessionBuilder.AUDIO_AMRNB)
.setVideoEncoder(SessionBuilder.VIDEO_H264);

Your response would be greatly appreciated.

It seems from the examples that launching the app the first time, it works well.
Closing and relaunching it, the video preview is black and it doesn't start until pressing the start button (before the preview was automatic when the app was launched).

Hello,

I am attempting to stream via RTSP from an Android device to another Android device. I have encountered the following problem however: on select wireless networks, i receive this error:
W/SystemClock﹕ time going backwards: prev 1895085352768999(ioctl) vs now 1895085352738482(ioctl), tid=31682

I have no idea what to do about this, and i'm using example 1 as the backbone for the streaming service.

Is there a way to save a rtsp stream as a playable file (i.e. mp4)?
I want to separate a stream into different files, that's why I'm not using androids MediaRecorder directly.

Thanks.

hy everyone
i am using libstreaming for streaming from Android device to Wowza server, but the issue is whenever i move my camera while streaming the video it shows blocky and jaggy patches in the stream, any suggestions???

We have incorporated your library into out app to stream a short video to our Wowza server similar to your example 3. This is working but we consistently get videos like the following:

https://www.dropbox.com/s/w3hcblfctmkko3p/libstreaming.mp4

The 3 problems we are consistently getting are the following:

• The first second of video doesn't change
• There are strange glitches in some frames
• The quality starts very bad but gets very good by the end

I can see that the kbps is variable and we need it to be fixed. For us, it is much more important that the entire video is good quality rather then it keeping up with real-time. Is it possible to fix the video quality and buffer if it cant keep up with the stream?

Any idea why some of the frames have glitches? It is very important that we get a good quality video.

We have tested this on a Samsung Galaxy S3 and Nexus 4.

Many thanks.

Although I have added:
< uses-feature android:name="android.hardware.camera.autofocus" / >

The camera still cannot autofocus
how to fix it?

camera.getParameters().setFocusMode(android.hardware.Camera.Parameters.FOCUS_MODE_CONTINUOUS_VIDEO);
may have to be set but I do not know how to access the camera instance of libstreaming

Is it possible to control the parameter of camera myself?

In onDestory of activity,
super.onDestroy();
mClient.release();
mSession.release();
have been added.
And other coding almost exactly with example 3.

but when I get into this activity again,
the surface view does not show anything.
(I have checked and confirm that the onDestory is run when I get back to the previous activity)
what's wrong?

Hi!

I am using this library for doing streaming for my android phone to VLC.

In a local network, I get to watch the streaming in VLC OK, but when i disable wifi and i Use 3g/lte, I don't get to watch the streaming in VLC.

I am using example 1 of libstreaming-examples

Is it possible? And how? Thanks!

hi,
i am using your library and my app has stopped. This is my error - http://pastebin.com/9Zdxgs3G
My device is a rooted tablet Asus Transformer TF101 with custom rom 4.3. App crashed when SurfaceView was instantiated. I must mention that this error appears only on tablets, On phones works well but i don't have a phone with Android 4.3 for testing.

In libstreaming-example-master of February 21th 2014, the example works correctly with the libstreaming-4.0.jar in libs directory. If I try the same example code with the last libstreaming-master.zip code, I've always the 'Callback buffer was too small !'
I need to use the libstreaming-master.zip because of some edits I did on it... so can't use the old .jar file in my project.

I really don't know where's the issue...

Hi! I'm using your library to stream to wowza server.

I have problems connecting to wowza:

Problem occurs on line:
mClient.startStream(1);

Wowza server is reacheable (I can ping it) and ip_address:1935 is visible from phone.

Do you have any workarounds?

Both preview and streaming is working fine for me with libstreaming until the view that I'm using for it is recreated, either by starting the activity a second time, or tilting the phone so that it changes between landscape and portrait.

The output is showing the message "sending message to a handler on a dead thread", and it's caused on the Session.Startpreview() method.

Both example2 and example3 downloaded here have the same problem when I modify them to allow screen rotation.

Anyone else who has/had this problem?

I am developing a simple app that let you record video/audio using this library and stream it over network. App has basically two SurfaceView (one for recording/preview and other for playback) . What I am doing is as follows

1. Start RtspServer service
2. Create SessionBuilder instance and configure it.
3. Create a session using SessionBuilder and start it (for preview and recording)
4. Create a MediaPlayer passing url "rtsp://127.0.0.1:8086" . Set the second Surface view for display and start
5. Connection is made to RtspServer but when "SETUP" request is sent, RtspServer start() the session created by the same SessionBuilder (as of step 2) in DESCRIBE request. It throws error in play().

Kindly let me know simple way of achieving the task of recording and playback on same device using RTSP. I checked spydroid camera but its code is right now complex for me to understand as I m short of time.

Callback buffer was too small ! Expected 518400 bytes, but got 38016

Quantity 640 x480 work but crash on resolution remain .

Using example 1 if I set:

.setAudioEncoder(SessionBuilder.AUDIO_AMRNB)
.setVideoEncoder(SessionBuilder.VIDEO_NONE);

How can I stream audio only with no video?

To facilitate easy and automated inclusion in other projects, libstreaming should use Maven, at least as an option.

Thanks for this great library and example apps! :)

I want to record the streams sent to Wowza (v3.6.3) using your example 3 app. I have followed these instructions:

https://github.com/fyhertz/libstreaming/wiki/Using-libstreaming-with-Wowza-Media-Server

But changed to rtp-live-record in live/Application.xml which seems to be the documented way to record streams. The app connects to Wowza fine and I get connect rtsp, create stream, unpublish stream, destroy stream and disconnect rtsp messages in the logs but no video file appears. If I add another folder to the rtsp path it creates a folder of that name in the applications/live/sharedobjects folder but that is it, no data.

I have tried changing many settings in Wowza and in your app but cant get the video data to be saved. I had to disable digest authentication to get the streams working but I cant see why that would cause the video files not to save. Do you have any idea what I need to do to save the streams as flv or mp4 files?

Any help you can give will be greatly appreciated!

Many thanks :)

I've been trying to stream videos to wowza in portrait mode. Setting preview orientation doesn't seen to have any effect. Is there any correction available to make it work?

Hello,

This is really a question on functionality probably rather than an "issue".

I just started investigating the API after a few failed attempts to build similar by scratch. My intention is to stream the camera preview from one Android device to another Android device with WifiP2pDirect. Any thoughts on the ability to do that? I started building my own activity which handles the p2p and will include the libstreaming code. Before I got in over my head I thought I'd check out the examples.

Based on my needs I thought example 2 would be the best route. I'm a little confused on what control I would send the stream to though. I know a SurfaceView is required for the camera, but what about the other end; how do I pipe the stream into the client control? I'm trying to run through the source, but there's a lot and I'd prefer not to waste too much time on a incompatible solution. The distance between the devices will be short and the stream will have to be as close to real time as possible.

Thanks for any help.

Hi,
I tried to read the stream with another phone using mediaplayer api:

• using h263 the mediaplayer stop with an unknown error code (1)

• using h264, I fixed some warning (like port number that has to be even and source declaration) but couldn't get it to work. The stream start I got a buffering event but the busser never get anything in it. And I see nothing bad in log appart from this:

  I/MyHandler( 174): dropping damaged access unit.
  I/MyHandler( 174): dropping damaged access unit.
  I/MyHandler( 174): dropping damaged access unit.
  I/MyHandler( 174): dropping damaged access unit.
  I/MyHandler( 174): dropping damaged access unit.

which happens a lot but diving in the Android sourcecode for this error did not ring any bells for me...
I don't know if you are aware of this issue or if you have any idea that could help me...

Regards,
Martin

I am having a color problem in the preview (the streaming is fine). The displayed color is wrong. It looks like the red and blue values are inverted. Once in a while the colors are correct (maybe 10% of the time). Should I look at how I am creating the rendering surface?

Hey,

This is an excellent library and it was really easy to setup and work with.

I've this small problem, when connecting using VLC there is a delay in the video (up to 2 seconds).

1. The android device and the PC are on the same WIFI network.
2. I tried both h.263/264 with and without audio
3. Frame rate set to 15
4. resolution 320x240
5. Tested with Galaxy S2 / S3

Ideas?

I'm interested in commercially licensing this library. I've reached out with the email that you provided, but haven't heard back. Can you provide a contact email address for discussing this?

Thanks,
Adam

As the heading states, the audio is not playing back on the VLC player, tried example 3...video is working pretty awesome.

Sorry, but I am not clear, is it ok that stream video have delays near 5-10 second on worse quality of video? And if yes, how we can decrease this delay?

I'm trying to streaming with the following quality:

"320x180, 30 fps, 250 Kbps";
"320x240, 30 fps, 250 Kbps";
"320x240, 25 fps, 600 Kbps";
"640x360, 30 fps, 600 Kbps";
"640x480, 30 fps, 600 Kbps";
"320x240, 30 fps, 300 Kbps";

but always the output on wowza is blocky and with some resolution is green screen. What the best parameter for a discrete streaming ?

Hi..

I am using Example 3 to stream from Nexus 7 to Wowza Server. I am using MediaCodec for encoding audio and video. I am using AUDIO_AAC for audio.

Initially audio-video are in sync. But with time video lags audio and the lag increases.
For example, after 20 min the video lags audio by 4 sec.

What is the issue? Can anyone help me to sync audio and video.

Thanks
Alan

Hi, I followed these instructions in Section 3. Creating Android Project to create a new project using libstreaming as a library:

http://www.androidhive.info/2014/06/android-streaming-live-camera-video-to-web-page/

Then I followed example2 to try and stream H.264 without RTSP. I deploy this app to my Galaxy Nexus and it fails with "The decoder did not decode anything." This is using VideoQuality.DEFAULT_VIDEO_QUALITY. If I use a larger resolution (640x480, supported according to a log entry from VideoQuality), the error changes to "The decoder input buffer is not big enough (nal=91280, capacity=65536)." Every combination of resolution, fps, and bitrate I've tried results in one of these two errors.

I've been struggling for days and cannot get libstreaming to work for me. Where do these errors come from and what do I need to look at to get them resolved?

Question also asked here, with code and log outputs: http://stackoverflow.com/questions/24128279/libstreaming-errors-decoder-buffer-not-big-enough-decoder-did-not-decode-anyth

(Somewhat unrelated, but I had to deviate slightly from example2: I'm building the session in a button click, not in onCreate(), because findViewById() was always returning null for my SurfaceView if I called it from onCreate().)

Thanks!

Hi @fyhertz, can I use this library as RTSP broadcasting server(not in Android phone) ? And if yes, can you provide some basic example ?

I have used example 3 for live broadcast from mobile. Now we have a requirement to publish the recorded video to wowza server. Can we do that using libstream?
Please share your thoughts..

I can't get voice working while streaming to wowza. I am using AAC codec. Here is some interesting bits of wowza log:

Wowza recognizes H264 and AAC codecs correctly. But in the player I am getting only video. Actually it only happens on some devices.

Any ideas what might go wrong with the sound?

I am following steps mentioned at:
https://github.com/fyhertz/libstreaming/wiki/Using-libstreaming-with-Wowza-Media-Server

when i start embedded JW player from localhost-apache, it says ID not found on server.

Do i have to create test.stream file in woowza and publish it using stream manager? if yes what should be the content of this stream file?

Hi.
I'm new to android but I'm trying to make an application that streams the audio form the mic through rtsp (part of school project). But somehow i'm not able to figure out how to make it.

in my onResume() i have:

    Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
    editor.putString(RtspServer.KEY_PORT, String.valueOf(myPort));
    editor.commit();

    SessionBuilder.getInstance()
    .setSurfaceView(mSurfaceView)
    .setPreviewOrientation(90)

    .setVideoEncoder(SessionBuilder.VIDEO_NONE)
    .build();

    this.startService(new Intent(this,RtspServer.class)); 

but how do i get the audio from the mic?

I've read that it needs a "hack" to write MediaRecorder on LocalSocket but how should i do it? And how i set it as the source to stream?

Thanks for your response and help.

Running Example 2 on Samsung Galaxy SII running Android 4.04:

After running example2 a few times, it operates normally just after clicking the start button, but when I click the stop button about 3/4 of the screen is about a one second loop of the last frame or so while the remaining portion is a live view of the camera preview but with a bad color format.

Hey!

I want to stream in the background, and as a service with this awesome library? Is it possible, if so how should i do it?

Thanks, Jonas

I am having an issue with TCP. It stops sending packets after a few minutes. If I stream to Wowza I can see that the connection is still open, but the data rate goes to zero and the app stops updating the debug console with sending messages (it only shows birate updates). Any ideas.

Hi, i'm trying to stream the audio from microphone in AAC-ADTS format.
I have the :

server = new LocalServerSocket(LOCAL_SOCKET_ADDRESS);
sender = new LocalSocket()
sender.connect(new LocalSocketAddress(LOCAL_SOCKET_ADDRESS));

and my MediaRecorder records into it:

myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.AAC_ADTS);
myAudioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
myAudioRecorder.setOutputFile(sender.getFileDescriptor());

I also have a LocalSocket receiver:

receiver = server.accept();

I also have the code to build the Session and Start the server:

SessionBuilder.getInstance()
.setContext(getApplication())
.setAudioEncoder(SessionBuilder.AUDIO_AAC)
.setAudioQuality(new AudioQuality(44100,128000))
.setVideoEncoder(SessionBuilder.VIDEO_NONE)
.build()
thisActiviry.startService(new Intent(thisActiviry,RtspServer.class));

I am checking the code of this libstreaming library but i can't find where can I connect the stream coming from this local socket to the one that goes out as a stream.

Can you please give a help how should i do this hack to stream the audio?

Thank You!
Gabriel.

hey hi, i was trying the example 2 application that uses this library with VLC on the other end as client playing using the sdp file. VLC recognises the audio track but its not receiving any audio blocks to decode. i guess something is not right with the audio streaming package. the spydroid app also had the same problem. i tried with both AAC and AMR. no use.

I'm trying Example 3 with Wowza .
All works fine on local network, but I have problem if smartphone try to connect on wowza by server public ip address.
I have set port forwarding for my wowza port, and when I click on start button, streaming starts, and in wowza manager I can see this connection in incoming streams.

The problem is that wowza not receive packets from android client.
If I see Network Throughput section, it show this :
bytes in 0 , bytes out 0
and of course video not shown.
From smartphone I can ping my public wowza's server ip, port 1935 is open and forwarded to local address of server. What I miss ? I must open and forward some other ports ?

smartphone android 4.1.2
wowza server on windows 7 (firewall disabled)

I tried to encode 640x480, but dequeueInputBuffer always fail,
so it change to mediarecoder method. but its quality is poor.
my question is

1. can mediacodec support 640x480 or it is just impossible?
2. how can i improve mediarecoder encoding quality (skip frame, not stable) ?

I really like this project and it is awesome!

How can we add auto focus to surfaceview while Recording stream

The manifest has minSdkVersion set to 9, but when I try to build it against version 15, it fails (android.media.MediaCodec wasn't added until 16).

What's the actual minimum version? Any chance it could be made to work for 15?

Thanks.

I am currently testing out the libstreaming library for use in recording videos to Wowza in the same way that the Example 3 works.

The recording of the videos works great, but the final video output seems to have some inconsistencies.

80% of the time the videos are recorded and playback correctly. The other 20% of the time, there is 8-10 seconds of the video in the beginning that doesn't have any metadata associated to it. When I play any of those videos in VLC, they play correctly but do not show any progress information or duration. When I try to play them back in Android using a simple VideoView, the video does not play at all.

What might cause this to happen?

Here is an example of a video that was recorded, and shows the issue that occurs: http://sharesend.com/wuk0lm1m

Here is an example of a video that I recorded a few seconds later that does not have any problems: http://sharesend.com/xbaks1fc

Also, here is the full implementation of the libstreaming library in my VideoRecorder class: http://sharesend.com/9pbac4nn

Finally, the device logs during playback: http://sharesend.com/am45eh1e

If I can provide any more info, just let me know.

Any help would be appreciated.
