Yes, unfortunately it doesn't work on some vivo devices: https://github.com/Genymobile/scrcpy/pull/3757#issuecomment-1454326127 https://github.com/Genymobile/scrcpy/issues/3791#issuecomment-1465214771

[rom1v]

Following the discussion from #3791 (because here is the right place for this issue).

I asked to pull the following .jar:

adb pull /system/framework/framework.jar
adb pull /system/framework/vivo-framework.jar
adb pull /system/framework/vivo-media.jar

Here are the links you provided:

• /system/framework/framework.jar
• /system/framework/vivo-framework.jar
• /system/framework/vivo-media.jar

adb shell ls /system/framework

The class VivoAudioRecordImpl is found in vivo-framework.jar. Here are the relevant parts:

public class VivoAudioRecordImpl implements IVivoAudioRecord {
    // …
    private Context mContext;
    // …
    public VivoAudioRecordImpl() {
        Application currentApplication = ActivityThread.currentApplication();
        this.mContext = currentApplication;
        if (currentApplication != null) {
            this.mAudioFeatures = new AudioFeatures(this.mContext, (String) null, (Object) null);
        } else {
            this.mAudioFeatures = null;
        }
    }
    // …
    public String isSupportSubMixRecording() {
        AudioFeatures.TagParameters tp = new AudioFeatures.TagParameters("vivo_remote_support");
        String mPackageName = this.mContext.getOpPackageName();
        String PackSha256 = getSignInfo(this.mContext, mPackageName, SHA256);
        tp.put(VivoPermissionManager.ACTION_KEY_PACKAGE, mPackageName);
        tp.put("component", PackSha256);
        tp.put(Calendar.CalendarAlertsColumns.STATE, VRequest.COMMAND_QUERY);
        String ret = new AudioFeatures.TagParameters(this.mAudioFeatures.getAudioFeature(tp.toString(), this)).get(Calendar.CalendarAlertsColumns.STATE);
        VLog.w(TAG, "isSupportSubMixRecording:" + ret + " PackSha256:" + PackSha256);
        return ret;
    }
    // …
}

However, I did not find from where it is called. According to your stacktrace, it's from android.media.AudioRecord. This class is available in your framework.jar, but does not call isSupportSubMixRecording().

In any case, the obvious first attempt is to make the context initialized. This is what I did here. However, it was not suffient. So I don't know what to do.

[yume-chan]

isSupportSubMixRecording is being called from AudioRecord's constructor,

        try {
            AudioAttributes attributes3 = attributes2;
            try {
                int initResult = native_setup(new WeakReference(this), this.mAudioAttributes, sampleRate, this.mChannelMask, this.mChannelIndexMask, this.mAudioFormat, this.mNativeBufferSizeInBytes, session, attributionSourceState.getParcel(), 0L, maxSharedAudioHistoryMs);
                if (initResult != 0) {
                    loge("Error code " + initResult + " when initializing native AudioRecord object.");
                    if (attributionSourceState != null) {
                        attributionSourceState.close();
                        return;
                    }
                    return;
                }
                if (attributionSourceState != null) {
                    attributionSourceState.close();
                }
                this.mSampleRate = sampleRate[0];
                this.mSessionId = session[0];
                IVivoAudioRecord iVivoAudioRecord = this.mVivoAudioRecord;
                if (iVivoAudioRecord == null) {
                    i = 1;
                } else {
                    String result = iVivoAudioRecord.isSupportSubMixRecording();  // <--- here
                    if (!"true".equals(result) || attributes3.getCapturePreset() != 8) {
                        i = 1;
                    } else {
                        i = 1;
                        this.mIsLiveApp = true;
                        this.mVivoAudioRecord.notifyGamecube(1);
                        this.mVivoAudioRecord.showNotificationStatus(true);
                        Log.d(TAG, "notifyGamecube start by " + this);
                    }
                }
                this.mState = i;
            } catch (Throwable th2) {
                th = th2;
                if (attributionSourceState != null) {
                    try {
                        attributionSourceState.close();
                    } catch (Throwable th3) {
                        th.addSuppressed(th3);
                    }
                }
                throw th;
            }
        } catch (Throwable th4) {
            th = th4;
        }

But looking at isSupportSubMixRecording, maybe vivo only allows some apps to capture remote submix, Even if we have all methods on context, it might still not work.

The query request was sent to system_server, which should be in services.jar or vivo-services.jar

[rom1v]

isSupportSubMixRecording is being called from AudioRecord's constructor,

I don't have this code in the AudioRecord.java from framework.jar. How did you decompile?

[yume-chan]

I'm using jadx https://github.com/skylot/jadx

[rom1v]

Oh, I used jadx too, but an old version (v1.2.0). With the latest (v1.4.6), I get the same source as you :tada:

[rom1v]

                IVivoAudioRecord iVivoAudioRecord = this.mVivoAudioRecord;
                if (iVivoAudioRecord == null) {
                    i = 1;
                } else {
                    String result = iVivoAudioRecord.isSupportSubMixRecording();

Maybe we can force mVivoAudioRecord to be null :see_no_evil:

[rom1v]

Let's try. @A-viral-dev please replace this binary in the v2.0 release, and run with scrcpy -Vdebug:

[A-viral-dev]

Still no audio

[yume-chan]

The call is in the constructor, must get the instance before the call, doesn't seem to be possible.

Full decompiled source: https://gist.github.com/yume-chan/0e061cc819865d78d717b226513c27e9

Maybe invoke the AudioRecord(long nativeRecordInJavaObj) constructor by reflection (with 0) and do all initialization (native_setup) in Scrcpy?

[rom1v]

The call is in the constructor

Oh, it was so far below that I thought it was in another method. :facepalm:

[rom1v]

That's with a newer build from dev branch. Ibdon't have any solution fornvivo phones.

But

1. ~~The captured video and the device performance become very slow and laggy when scrcpy is running.~~ Its my home wifi, its working fine on usb and other network.
2. Another issue is that the sound from the device is only played on the computer and not on both devices. Maybe WAD.

great sound start to work

Nice. Now let @rom1v decide whether to use this as a fallback path.

the sound from the device is only played on the computer and not on both devices.

Yes this is expected. Remote submix is like a sound output (like a earphone), so all audio outputs are redirected to it.

[rom1v]

@yume-chan Great :+1:

However, I'm a bit worried that it is a very specific/fragile code in the long run. On Android 11 it fails (because missing AttributeSource, but that's probably easy to fix). On Android 13 (non-vivo), it currently works though.

[yume-chan]

I think it should be used as a fallback, if the normal path fails, try this one instead.

It works on vanilla Android 12/13, but if another vendor also added some code to the constructor (that works with Scrcpy now), then the code will break them instead.

So no need to support Android 11, unless another vivo user with Android 11 reported an issue. Also little effort is required to maintain it, if it stopped working, I don't care, we can always declare the device as can't be supported.

[rom1v]

OK, maybe. The code could may be moved in a new method Workarounds.createAudioRecord(), and with native reflection (not to add a joor dependency). I think it may be adapted for Android 11 too (just removing the AttributeSource stuff).

Please tell me if you want to work on a proper PR to implement it. Otherwise, I could do it later.

[yume-chan]

I can create a PR this weekend.

Please try this (only for testing whether vivo has an allowlist for capturing remote submix): scrcpy-server.zip

@631jike Please test this version: https://github.com/Genymobile/scrcpy/pull/3862#issuecomment-1561871804

(To Vivo device users)

The Vivo issue with audio is fixed on dev branch and it should work on the future scrcpy 2.1 release.

However, I'm afraid that a work-in-progress fix (#4015) for another device might break the fix for Vivo phones, so I need you to test the following version to make sure scrcpy 2.1 will still work on Vivo phones.

It basically contains the WIP fix branch and the following diff:
