Would be great to get update for null safety now that Flutter 2 has been released.

I am getting the below issue when I use the camera_with_rtmp as a component. However when I run the example given in the github folder, it seems to be working without issue. I'd appreciate some help. This working yesterday and suddenly it stopped working.

I am an experienced Flutter developer but new to streaming and interested in learning how to use this plugin for streaming video. Would it be possible to use the example app to stream video directly to my Windows computer with Media Player, or to another mobile using VLC for Android, or something like that? I. e. without having to set up a media server or learning Wowza for example. Simple step by step instructions for running the example app like that would be much appreciated! (If it is possible.)

While trying to build for Android I get the following errors.

I think you are building this plugin with a really old version of Flutter.
I think you need to upgrade your version of Flutter/Xcode/Android. (developer of this library)

Hi,

I've successfully implemented this library into a test project. First of all, thanks for making this!

Broadcasting works fine, except there is an issue with the front facing camera, at least on the Android devices I am able to test on. The preview in the app looks correct, however the resulting stream has the front facing camera upside down. I did some digging and found that the issue doesn't stem from your library, but rather Android itself, however I thought it might be worth letting you know to see if we can brainstorm a fix.

Affected devices: Pixel 3a, Pixel 2XL (potentially more?)

The problem derives from an issue in the CameraManager class, part of Android's camera2 API, which this library uses. The CameraCharacteristics you get thinks the orientation of the front facing camera is 180 degrees off of the rear facing camera for some reason. I was able to log it here:

2020-06-29 21:50:24.707 29763-29763/com.example.rtmptest D/===RTMP Test===: name: 0; lens direction: back; orientation: 90
2020-06-29 21:50:24.710 29763-29763/com.example.rtmptest D/===RTMP Test===: name: 1; lens direction: front; orientation: 270

The method you can use to see this is this:

CameraCharacteristics characteristics = manager.getCameraCharacteristics(camera);
int sensorOrientationDegrees = characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);

Where sensorOrientationDegrees refers to 0, 90, 180, or 270. As you can see in the log above, the front facing camera is inverted (270) compared to the rear (90). What's interesting is that this only happens in portrait mode, in landscape, it works fine:

2020-06-29 21:50:22.152 29763-29763/fitness.classmate.rtmptest D/===RTMP Test===: name: 0; lens direction: back; orientation: 180
2020-06-29 21:50:22.154 29763-29763/fitness.classmate.rtmptest D/===RTMP Test===: name: 1; lens direction: front; orientation: 180

I've dug around for solutions to this but haven't had any luck with what little I've found. The library you derived the Android solution from also faces this same problem, so it's not just you. Given that I can use Hangouts and other video apps on this device without being upside down, I know there is a solution, I just can't find it yet. I just wanted to create this issue here so that others might be able to see that they're not crazy if they run into this wall like I did, and hopefully spark a conversation that can lead to a solution.

Thanks!

Hi owner, this is an awesome plugin. I can work with IOS perfectly. But in Android, after I click startVideoStreaming, I check my server is not found image video so I guess it has the same problem as this issue: pedroSG94/RootEncoder#721. I notice you have an option androidUseOpenGL in function startVideoStreaming(), but it isn't used in native code

Hello ! I using the example from pub dev .
When I am running the debug app. It shows No camera found and nothing works.
I have tried two phones : One plus 6 and Redmi 8A dual
How to fix this.

My requirement is to capture video by camera then add an overlay at bottom of screen (something like fixed text/message) then want to stream screen output (capturing video + overlay text) on RTMP. Could you please suggest me how can I do this? Thanks a lot.

After installing camera_with_rtmp: ^0.2.2 onto my project, I started to get the following error:

My Flutter version: 1.17.3
My Dart version: 2.8.4

Is there a way to draw on the camera frames and transmit them via the RTMP?

I want to show the date-time on-screen during streaming as well, currently, we have this feature yet?

Hi,

I am exploring this for my streaming project. i am using Wowza cloud. Given example(in this repo) working perfectly. But when i switch the camera while streaming, the stream got disconnecting.

I am using the example which is given in this repo. Can someone help me here.

Note: I don't know whether it is bug or not.

Thank you.

I'm using the youtube live stream api for streaming live videos.
Whenever i start to the live stream, my video becomes dark.

It happens after i enable androidUseOpenGL property. Cannot disable because it leads to video freeze on stream start.

This is how my controller is initialized.
`void getCameraDescription() async{
var cameras = await availableCameras();
cameraDescription = cameras.length > 1 ? cameras[1] : cameras[0];

cameraController = CameraController(cameraDescription, ResolutionPreset.medium, enableAudio: true, androidUseOpenGL: true);

cameraController.initialize().then((value){
  if(!mounted)
    return;
  setState(() {

  });
});

}`

Live stream start code.
`Future startVideoStreaming() async{
if(cameraController == null){
return null;
}
if(!cameraController.value.isInitialized){
return null;
}
String myUrl = "rtmp://a.rtmp.youtube.com/live2/";

try{
  await cameraController.startVideoStreaming(myUrl);
}
catch(e){
  print(e);
  return null;
}

return myUrl;

}`

Disposed system still running in the background. It has a thread doing something since it continues to show debug messages about dropping frames. Need to tear down the rtmp system correctly.

Hi!
I am running your demo app on a physical IPhone and am not able to get the RTMP stream to switch from portrait to landscape.
I really just need the stream to in landscape.

Not sure if this is a bug or intended.

Please make it for web

is there any way to close video stream (or send picture) and only send audio data when make streaming. Because some apps like whatsapp, user can close camera and only make audio stream . I reviewed your source code but i cant figure out.

Issue description

Attempting to record video crashes app on iOS. Android is unaffected

How to reproduce

Version Info

• flutter_rtmppublisher : bec8781
• Xcode: 11.5 (11E608c)
• Flutter: Flutter 1.17.3 • channel stable
• Device: iPhone 6s (12.3.1) AND iPhone Xs Max (13.3.1)

Steps

1. Run example via Xcode
2. Select either front or rear camera
3. Ensure audio is enabled
4. Press Icons.videocam
5. App will crash w/ exception

Exception:

I try to run example app, but it crashes on
await controller.startVideoStreaming(url);
No messages, app just disappears
iOS 12.4, camera and microphone privileges are given

Stream part is ok but Is there any way to show another rtmp stream in video player? It can be useful for video chat applications.

I am trying to browser overlay, something like OBS but with ffmpeg i am getting very less frames. I can convert my html into image but can i merge it with the camera stream?

When I have been testing code I found one problem. After taking one photo I cannot take another or start a stream.

How to stream camera and preview Camera stream is you have any idea please tell me

I want use both camera feeds at the same time in my app, have any option for that?

Need to put this in the app.gradel file
packagingOptions {
exclude 'project.clj'
}

It comes from the dependency on the rtmp library being used, not sure how to get rid of it in the library. Tried a few things but it kept turning up, putting this in your android file itself fixes the problem.

When I start example app and select camera the preview shows camera picture ok.
But when I start rtmp streaming, the camera picture freeze, and one cannot see on the phone what is streamed.

The system stops sending correctly and doesn't try and recover if the network stops working correctly or if the user resets up the system by doing a camera switch. Fix to make it work twice.

Hello, thank you for the plugin, we tried the plugin on both platforms, and seems on IOS query arguments in rtmp URLs erased i think here: https://github.com/pinkfish/flutter_rtmppublisher/blob/master/ios/Classes/FlutterRTMPStreaming.swift#L38 on Android rtmp urls with query works fine.

I tried to put the wrong RTMP url and it's still record streaming, it's supposed to be a streaming error.
the code controller.startVideoStreaming(url) is not get catch although we put the wrong RTMP url.
How to detect that RTMP url has valid or invalid?
Thank you

We are working with livepeer (https://livepeer.org/) and are facing an issue in development. The livepeer sends an EOF when the connection state resets. This is the type of behavior that most RTMP sdks expect. However, flutter_rtmppublisher closes the connection if EOF is received. It would be great if the connection stays open on EOF.

Now that Flutter has desktop support in the dev channel, is there a plan to add desktop support to this package?

The camera plugin has a Zoom feature (flutter/plugins#3315). Will this be imported to the package?

Zoom feature was introduced on version camera 0.6.2.

I want to add date-time into the video during streaming like this, I can add it as Text Widget over VideoPreview but sometimes the viewer they’re not using Mobile App there might be used the web to view the video stream of publishers, any solution help, please

Hey, I love that you created this library, really wish I could pay you somehow cause you are saving my ass.

Anyhow; I have some build errors when trying to build this for iOS. Something to do with the POD Logboard, perhaps it just needs updating.

I think you need to upgrade your version of Flutter/Xcode/Android. (developer of this library)

Running the sample on a physical iPhone 6S, and the video streaming does not work. I am trying to stream to an RTMPS URL online and the livestream simply does not appear. No errors appear in the console.

Android works just fine.

Can anyone advise?

There is ndk level bug that manifests while dispose() method calls.
com.whelksoft.camera_with_rtmp.Camera.kt

fun dispose() {
  close()
  flutterTexture.release()
  orientationEventListener.disable()
}

flutterTexture.release() method causes exception but it is impossible to catch it in kotlin since it is lower level exception. Example of exception log:

Steps to reproduce (Android 8.1):

1. User starts streaming (creates controller)
2. User switches camera (disposes prev controller and creates new one synchronously)
3. Exception occurs after 1 or more switches.

For iOS
Also, I can't record video. Application on iPhone crashes and closes

@pinkfish Can You check the ability to store video locally?

Hi,
I am a novice in RTMP.
I'd like to upload the camera recording on the phone into the MediaLive of AWS.
I have found the below in your sample codes.

TextEditingController(text: "rtmp://34.70.40.166:1935/LiveApp/815794454132232781694481");

If I change the above rtmp url into the MediaLive of AWS, do it can upload the camera recording?

Hi,
The aspect ratio on the camera preview is fine but not on the output of the stream. The output is a bit cropped and doesn't respect the aspect ratio.
Do you have any solution for this issue ?
Thanks,
Gaël
