Hello.
I am making good use of the library you provided.

I am experiencing an issue with a device running Android sdk 16 specifically, the Galaxy Camera (Samsung EK-KC120L)—where the transfer does not seem to be working.
Could you please look into this?

private boolean prepareEncoders() {
    int width = 640;
    int height = 480;
    bitrate = 500 * 1024;

    boolean prepareVideo = rtmpCamera.prepareVideo(width, height, 30, bitrate, CameraHelper.getCameraOrientation(this));
    boolean prepareAudio = rtmpCamera.prepareAudio();
    return prepareVideo && prepareAudio;
}

if (prepareEncoders()) {
      rtmpCamera.startStream(ffmpeg_link);
}

public void startStream(String url) {
    streaming = true;
    if (!recordController.isRunning()) { <--- this is null
      startEncoders();
    } else {
      requestKeyFrame();
    }
    startStreamImp(url);
    onPreview = true;
}

I have attached the test source code. The preview is included in the camera setup, but the preview only appears when startStream is called, at which point the following error occurs. Could this be due to the device's low specifications?
Could you please look into this issue?

Hello,

Did you tried using a lower resolution? (320x240). Maybe your device encoding is really limited and support really low resolutions. At least that is the case using an emulator.
If the problem persists, can you share a full logcat when you call startStream method?

[oertion]

When I set it to 320 x 240, the preview doesn't even appear. This log is from a run at 640 x 480. Thank you.

Hello,

Try this version:
d27a7d2

Also, could you get the log this way? The previous one was filtered by your app package, so the native crash of the mediaserver process (which maybe is what kills the camera) is missing from it.

Please don't use the Android Studio Logcat window, use a terminal. Start this before reproducing:

adb logcat -c
adb logcat -v threadtime -b main -b system > rootencoder.log

Then open the app, let it call startStream, wait until the preview freezes and keep it running ~20 more seconds. Then press Ctrl+C and attach rootencoder.log file.

Right after that, without rebooting the device:

adb bugreport > bugreport.txt

[pedroSG94]

Hello,

Thanks, the log has what was missing. It is not a library bug, it is a bug in your device's hardware encoder.

In rootencoder.log (line 2739 and the tombstone that follows):

F/libc: Fatal signal 11 (SIGSEGV) at 0x44ce3000, thread 22435 (AvcEncBufPrc)
pid: 20918, tid: 22435, name: AvcEncBufPrc  >>> /system/bin/mediaserver <<<
backtrace:
    #00  memcpy+172                                 /system/lib/libc.so
    #01  SEC_VideoEncodePreprocessor_InputData+732  /system/lib/libsomxcmn.so
    #02  SEC_OMX_VideoEncodeBufferProcess+240       /system/lib/libsomxcmn.so

OMX.SEC.avc.enc (Samsung's hardware H264 encoder) asks for an input buffer of 640x480x3/2 = 460800 bytes, we fill it with exactly that, and then it reads 475136 bytes from it because it expects each plane padded to 8KB. It runs off the end of the shared memory and crashes mediaserver. Since on Android 4.1 the camera lives in that same process, the camera dies with it: that is your Camera server died / Error 100, about 6 seconds later (the delay is just the crash dump being written).

This happens with any resolution, and that encoder only offers color format 19 on your device, so there is nothing to switch to. Nothing the library sends is wrong.

The workaround is to use the software encoder for video instead. Call this before prepareVideo:

rtmpCamera1.forceCodecType(CodecUtil.CodecType.SOFTWARE, CodecUtil.CodecType.FIRST_COMPATIBLE_FOUND);

Also, print the codec list first so you know which software encoder you have and, above all, the maximum resolution it supports (a software encoder on that hardware will be much more limited than the Samsung one):

for (String info : CodecUtil.showAllCodecsInfo()) Log.i("Codecs", info);

Then set a resolution within that limit in prepareVideo.

Could you try it and tell me if it works? If it fails you will see Valid encoder not found in the log, which would mean the device has no software H264 encoder available.

[oertion]

An exception occurs when calling showAllCodecsInfo, and prepareVideo returns false after applying the forceCodecType action.

bugreport.txt
rootencoder.log

    private boolean prepareEncoders(boolean audio) {
        for (String info : CodecUtil.showAllCodecsInfo()) Log.i("Codecs", info);  **<-- Exception occurs**
        int width = 640;
        int height = 480;
        bitrate = 460800;

        rtmpCamera.forceCodecType(CodecUtil.CodecType.SOFTWARE, CodecUtil.CodecType.FIRST_COMPATIBLE_FOUND);
        rtmpCamera.prepareVideo(width, height, 30, bitrate, CameraHelper.getCameraOrientation(this));  **<-- Return value: false**
        rtmpCamera.prepareAudio();
        return true;
    }

VideoEncoder not prepared yet. You must call prepare method before start it

[pedroSG94]

Hello,

showAllCodecsInfo crashed because a codec is break. I did a fix to avoid it. You can try with this version:
15f5a40

Share me the log of showAllCodecsInfo and try with software encoder again. if the problem persists and after get the codecsinfo logs we can know the way to fix it. If possible use other encoder if not, we can try do a custom change only for your case.

[pedroSG94]

If nothing is working. I did a commit that maybe fix the problem with your hardware encoder. Try this version without forceCodecType line:
294385b

Remember that this last commit is not a fix that will be released since it is a device specific fix but will help you work with your device.

[oertion]

I really appreciate you taking the time to look into the issue.

implementation "com.github.pedroSG94.RootEncoder:library:

    bitrate = 460800;

    rtmpCamera.forceCodecType(CodecUtil.CodecType.SOFTWARE, CodecUtil.CodecType.FIRST_COMPATIBLE_FOUND);
    rtmpCamera.prepareVideo(width, height, 30, bitrate, CameraHelper.getCameraOrientation(this));
    rtmpCamera.prepareAudio();
    return true;
}

Attaching the logs.

video transmission is distorting the image.

[pedroSG94]

Hello,

Try this version:
83ef4ab

This should fix the image distortion
