请教一下 MediaCodec 解码视频流问题

需求是一直接受后台返回的视频流数据，使用 MediaCodec 解码视频 SurfaceView 播放。后台数据只有宽、高、mimeType 、时间戳 pts 、数据包；我该怎么配置 MediaFormat ？当前遇到的问题是有一台定制平板什么视频都播放不了，dequeueOutputBuffer 一直返回的是-1，其它的设备都是能够正常播放；麻烦各位帮忙看看。

代码：

收到后台数据

                Object[] objects = message.getObjects();
                int res = (int) objects[0];
                int codecid = (int) objects[1];
                int width = (int) objects[2];
                int height = (int) objects[3];
                byte[] packet = (byte[]) objects[4];
                byte[] codecdata = (byte[]) objects[5];
                long pts = (long) objects[6];
                String mimeType = Macro.getMimeType(codecid);
                int length = 0;
                if (packet != null) {
                    lastPushTime = System.currentTimeMillis();
                    length = packet.length;
                    if (!saveMimeType.equals(mimeType) || initW != width || initH != height || mediaCodec == null) {
                        //有变更则重新初始化 MediaCodec
                        if (mediaCodec != null) {
