Android MediaCodec/MediaExtractor-尝试将InputBuffer从第二个MediaExtractor排队到第二个解码器时出现libexynosv4l2错误

在我尝试将视频与MediaCodec连接的过程中，我尝试使用两个

MediaExtractor

s，每个都与

MediaCodec

s配对作为解码器。我尝试本地化提取器和解码器循环，使它们看起来像这样：

private void videoExtractorLoop(MediaExtractor localVideoExtractor, MediaCodec destinationDecoder, ByteBuffer[] destinationDecoderInputBuffers)
{
    boolean localExtractorIsOrig = (localVideoExtractor == videoExtractor);
    boolean localDoneIndicator = localExtractorIsOrig ? videoExtractorDone : videoExtractorAppendDone;

    while (mCopyVideo && !localDoneIndicator && (encoderOutputVideoFormat == null || muxing)) {
        int decoderInputBufferIndex = destinationDecoder.dequeueInputBuffer(TIMEOUT_USEC);
        if (decoderInputBufferIndex == MediaCodec.INFO_TRY_AGAIN_LATER) {
            if (VERBOSE)
                Log.d(TAG, "no video decoder input buffer");
            break;
        }
        if (VERBOSE) {

                    + decoderInputBufferIndex);
        }
        ByteBuffer decoderInputBuffer = destinationDecoderInputBuffers[decoderInputBufferIndex];
        int size = localVideoExtractor.readSampleData(decoderInputBuffer, 0);
        long presentationTime = localVideoExtractor.getSampleTime();
        if (VERBOSE) {
            Log.d(TAG, (localVideoExtractor == videoExtractor) + " video extractor: returned buffer of size "
                    + size);
            Log.d(TAG, (localVideoExtractor == videoExtractor) + " video extractor: returned buffer for time "
                    + presentationTime);
        }
        if (size >= 0) {
            if(localExtractorIsOrig)firstDecoderFinalFrameTimestamp = presentationTime;
            destinationDecoder.queueInputBuffer(decoderInputBufferIndex, 0, size, presentationTime, localVideoExtractor.getSampleFlags());
        }

            //videoDecoder.queueInputBuffer(decoderInputBufferIndex, 0, 0, 0, MediaCodec.BUFFER_FLAG_END_OF_STREAM);

        }
        break;
    }
    //Video Decoder code end
}

我在通常的ExtractDecodeCodeTest中分别使用这些函数来代替提取器代码和解码器代码。我只需传入我想要使用的

媒体提取器

和解码器

媒体编解码器

，我希望该函数能与所述提取器和解码器进行通常的提取/解码循环

当我将这些函数用于第一对提取器-解码器时，它们工作得很好。但是，当我在第一个提取器-解码器对的工作完成后立即将它们用于第二个提取器-解码器对时，我从行

destinationDecoder.queueInputBuffer（decoderInputBufferIndex，0，0，MediaCodec.BUFFER\u FLAG\u END\u OF_STREAM）中得到以下异常：：

W/System.err:android.media.MediaCodec$CodecException:Error 0xfffffff3

编辑：

我仔细查看stacktrace，发现了这些：

我需要在解码器设置中更改什么？
您找到解决方案了吗？
