Question

Agora local video preview stopped working on last repo code changes.

shoebkhan88 opened this issue 10 months ago · comments

Describe the bug
Local video preview was working both on android and ios using version 6.2.2. After the last code changes done on Agora-Flutter-SDK, local preview turned black screen. Remote video is fine.
Scenario:
Caller:

Can see remote user video
Cannot see local video (but local video transmitting)

Receiver:

Can see remote user (caller) video
Cannot see local video (receiver-side but local video transmitting)

This issue is only for engine.startPreview() where local preview has been broken.

Framework: Flutter
Tests performed on real device (Android and IPhone)

Console log:

After the last code changes done on Agora-Flutter-SDK

Do you mean the code on the main branch?

BTW, can you try our example to see if there same issue?

Can you please verify that UID range is incorrect ??????

### I believe this issue has to deal with Agora SDK primary camera access along with internal localAudioTrack.
Also can you please help me understand what it means by CallbackOnError errCode 1166 ??? Could not find reference

Closing this thread as fixed by changing following configuration:
Behavior changes: Apps targeting Android 13 or higher

Adding below in android manifest

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO"/>
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO"/>

Reference: https://developer.android.com/about/versions/13/behavior-changes-13

LocalPreview VideoCanvas only takes local uid=0, even if local uid is dynamic in other code logic.
Pass 0 to videocanvas.

Thank you @littleGnAl. Closing this thread as solved.
