Video Black Screen but audio, join channel is working fine #53

codesundar · 2019-12-20T14:20:26Z

When I download this example project, it's working perfectly.

but when I create a new flutter project & copy the same code, it only shows a black screen for video. I tried this for the last 15 hours but still couldn't figure out

What I did

Created New Flutter project
Copy the lib folder from this example to the newly created project
Updated pubspec.yaml
Updated Permissions with AndroidManifest.xml
Updated my own APP_ID

After running the app, it shows only a black screen for video. All remaining staff working fine such as audio, join the channel, remove the channel

Flutter Doctor Output:

I found this error when a user joins the channel

@plutoless I have also noticed that the black screen is for local video, where the remote video is working fine

stefanschaller · 2019-12-22T11:00:57Z

Yes, I have switched the camera too, but still facing the same black screen.

As I mentioned before, this repo example is working perfectly. but when I create my own & replace the code, it's not working.

I think some issue with accessing camera because I tried like this

I download this repo & run on one device. (mobile-1)
I created a new project & replaced the code & run on another device (mobile-2)
Now, I can see a mobile-1 video in mobile-2 but mobile 2 video is not showing in mobile 1 (simply black screen & mobile 2 local video also black screen

@plutoless please help me to fix this asap.

plutoless · 2019-12-24T05:37:56Z

when you create the new project. have you granted permissions? is your android project settings aligned with our example?

plutoless · 2019-12-24T05:38:15Z

maybe you can post your project here. i can help take a look directly.

@codesundar i just did a quick investigation with my colleague this afternoon. it seems flutter has changed its embedding mechanism to v2 in latest version. in this case somehow registerWith function will be called twice, which leads to problems.

you can either,

downgrade in your Manifest.xml from 2 to 1
wait till we upgrade our plugin to support v2

codesundar · 2019-12-24T11:54:28Z

@plutoless Thanks for your reply.

can you please help me, how to downgrade?
How long it'll take you to upgrade?

rlee1990 · 2019-12-24T20:52:01Z

@plutoless it seems like this may be the same issue that I am having. I tried changing the Manifest from 2 to 1 but the app will not build once that is done.

plutoless · 2019-12-25T02:20:07Z

@rlee1990 @codesundar maybe you can take a look first how you can generate a new project using v1 flutter tool. we are working on upgrading our module to support v2 embedding for the moment. will provide response as soon as we have

LichKing-2234 · 2019-12-25T02:42:41Z

@rlee1990 @codesundar
please remove this code from your MainActivity
GeneratedPluginRegistrant.registerWith(flutterEngine)
new version of flutter will run this function by itself, I think it's a bug of flutter
Tips: keep flutterEmbedding to v2, when you run flutter, the generated file will change

LichKing-2234 · 2019-12-25T02:46:08Z

LichKing-2234 · 2019-12-25T02:53:04Z

run registerWith twice, will register all of the plugins twice, so it can cause problems

Yes that worked for me also for android now I have to see what happens for IOS.

rlee1990 · 2019-12-31T01:08:57Z

@LichKing-2234 why is this closed the workaround you provided is not a fix, it will cause other packages that use flutter to break.

@anon-000 our sdk have supported v2 plugin. any problem?

anon-000 · 2021-03-02T15:36:24Z

I have removed that generatedPluginregistrant in MainActivity.kt but still that black screen is showing. I have given all the permissions and also checked the tokens and the app id .

When i downgrade the version of the agorartc plugin to 1.* it's working fine but when i use the latest version or the versions above 3 then it's not working.
RtcLocalSurface becomes black.

Please help me if you can otherwise last option for me is to downgrade the version and use it.

LichKing-2234 · 2021-03-03T03:03:18Z

@anon-000 The 1.x version is out-of-date, if you want to use the 3.x version, pls refer to our example to migrate
