The decoder did not decode anything on Marshmallow

[alexbatashev]

I'm trying to get libstreaming work with Marshmallow. However, it doesn't encode anything.

Here is how I'm doing it:

        Camera tmpC = Camera.open();
        List<Camera.Size> sizeList = tmpC.getParameters().getSupportedVideoSizes();
        tmpC.release();

        VideoQuality vq = new VideoQuality(sizeList.get(0).width, sizeList.get(0).height);

        mSession = SessionBuilder.getInstance()
                .setContext(ctx)
                .setAudioEncoder(SessionBuilder.AUDIO_AAC)
                .setAudioQuality(new AudioQuality(128000,44100))
                .setVideoEncoder(SessionBuilder.VIDEO_H264)
                .setVideoQuality(vq)
                .setSurfaceView(surfaceView)
                .setPreviewOrientation(90)
                .setCallback(this)
                .build();

Any suggestions?

Which device are you using? Nexus 5, 6, and 7 2013 work on marshmallow for me. However, alot of weird devices, like a specific htc desire, suffer this problem. I think there's something wrong with the encoder debugger detection. We should really figure this out.

I tested it on my HTC One M8 with SkyDragon ROM.

[alexbatashev]

I'm still unable to get it work. Tried different ROMs, but all I get is that error message and this strange screen.

Is that the direct camera preview or after it's rendered in opengl? If it's what's rendered in opengl then I would guess it's a hardware problem.

That's a camera preview. The picture is moving and I can recognize objects around. So, it is just a distorted image. When I click record button, everything freezes.

Try using resolution 720 x 480. Looking at the android compatibility document, it's the only resolution guaranteed to be supported on all devices. I have a sneaking suspicion that this is what the default resolution should be for this library. I've ordered some devices in the mail that users are reporting problems on. I'll update if I find solutions.

[alexbatashev]

That seems to be working for me. However, I hear no sound while playing the video with ffplay. Anyway, that's better than nothing. Thank you very much.

@sbaar Is this issue solved? I also met this issue when I use resolution 1920x1080

[sbaar]

There has been no work done on the library in a long time, so no. Are you getting this on 320 x 180 640 x 360 and 1280 x 720 too? On every resolution your camera supports?
