问有没有办法从MPEG TS文件或HLS直播流中提取元数据

EN

MediaExtractor extractor = new MediaExtractor();
extractor.setDataSource(MEDIA_PATH);//MEDIA_PATH is your http path of mpeg ts file
for (i = 0; i < extractor.getTrackCount(); i++) {
                MediaFormat format = extractor.getTrackFormat(i);
                String mime = format.getString(MediaFormat.KEY_MIME);
                /*if (mime.startsWith("audio/")) {
                    extractor.selectTrack(i);
                    decoder = MediaCodec.createDecoderByType(mime);

                    if(decoder != null)
                    {
                        decoder.configure(format, null  /*surface*/ , null  /*crypto*/ , 0  /*flags*/ );
                    }

                    break;
                }*/ //this commented code may not useful for you. If you wanna you can use..
