Question

我正在编写一个解码视频样本并播放解码样本的应用。为此我使用MediaExtractor API。配置解码器时我收到错误。这是我的日志

这是我的代码

    for (int i = 0; i < videoExtractor.getTrackCount(); i++) {
                    MediaFormat format = videoExtractor.getTrackFormat(i);
                    String mime = format.getString(MediaFormat.KEY_MIME);
                    if (mime.startsWith("video/")) {
                        videoExtractor.selectTrack(i);
                        videoExtractorForSeek.selectTrack(i);
                        videoDecoder = MediaCodec.createDecoderByType(mime);
//error is in below line
                        videoDecoder.configure(format, surface, null, 0);
                        break;            
                    }
                }

此代码适用于Android 4.2及更高版本。并在4.1.2中失败
