Question

我正在使用libstreaming库并尝试使用RtspClient和MedicaCodec API进行流式传输。我正在测试一个带有android 4.4的galaxy s3。问题是，无论我使用缓冲区来缓冲还是表面缓冲，我都会收到此错误：java.lang.IllegalStateException: The decoder input buffer is not big enough (nal=181322, capacity=65536).和java.lang.RuntimeException: The decoder did not decode anything. MediaRecorder api工作正常，但质量很低我无法判断我面前有一只猫或一条狗。

这是我的代码：

请帮忙！我绝望了！

更多数据的请求来得晚，但我找到了解决方案。很多帖子都说我必须修改libstreaming库。我改变了：

public MediaStream() {
        // code change
        mRequestedMode = MODE_MEDIACODEC_API_2;
        mMode = MODE_MEDIACODEC_API_2;
    }
public synchronized void start() throws IllegalStateException, IOException {

        if (mDestination==null)
            throw new IllegalStateException("No destination ip address set for the stream !");

        if (mRtpPort<=0 || mRtcpPort<=0)
            throw new IllegalStateException("No destination ports set for the stream !");

        mPacketizer.setTimeToLive(mTTL);

        // code change
        encodeWithMediaCodec();
}

并且必须调用表面方法mSession.getVideoTrack().setStreamingMethod(MediaStream.MODE_MEDIACODEC_API_2);并且必须将我的配置限制为这些值：http://developer.android.com/guide/appendix/media-formats.html#recommendations 或者它会崩溃或绿屏或其他什么。
