Here is my code;

FFmpegRecorderActivityParams.Builder paramsBuilder =
        FFmpegRecorderActivityParams.builder(RabonaChooseVideoActivity.this)
                .setVideoOutputFileUri(destFile);

paramsBuilder.recorderParamsBuilder()
        .setVideoSize(new ImageSize(640, 480))
        .setVideoCodec(EncoderParamsI.VideoCodec.H264)
        .setVideoBitrate(100000)
        .setVideoFrameRate(30)
        .setVideoImageFit(ImageFit.FILL)
        .setVideoImageScale(ImageScale.DOWNSCALE)

        .setAudioBitrate(100000)
        .setAudioChannelCount(2)
        .setOutputFormat(EncoderParamsI.OutputFormat.MP4);

Intent intent = new Intent(RabonaChooseVideoActivity.this, FFmpegRecorderActivity.class);
intent.putExtra(FFmpegRecorderActivity.REQUEST_PARAMS_KEY, paramsBuilder.build());
startActivityForResult(intent, REQUEST_TAKE_CAMERA_VIDEO);

@alcntml When does this happen? Could you describe your interactions with the phone before the error?

• Is it right after you stop recording?
• Is it after the first clip or after multiple?

facing the same error right after I stop recording the first clip.
