Error al instanciar mediaextractor al usar setDataSource ()

Estoy intentando extraer la pista 0 (pista video) de un archivo del avi usando MediaExtract y codificar al formato h264 usando MediaCodec. Así es como configuré mediaCodec

public MediaCodec configure_codec(){ Log.d("OUT","configure starts"); MediaCodec codec = MediaCodec.createEncoderByType("video/avc"); MediaFormat format = MediaFormat.createVideoFormat("video/avc", 320, 240); format.setInteger(MediaFormat.KEY_BIT_RATE, 700000); format.setInteger(MediaFormat.KEY_FRAME_RATE, 15); format.setInteger(MediaFormat.KEY_COLOR_FORMAT,MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Planar); format.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5); //Configure codec for encoding codec.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE); Log.d("OUT","codec configured"); return codec; } 

El problema que estoy enfrentando es en esta parte.

 public MediaExtractor extract_video() { MediaExtractor extractor = new MediaExtractor(); //problem in this line try{ extractor.setDataSource(file_in); }catch(Throwable th){ Log.d("OUT", th.getMessage()); } MediaFormat format = extractor.getTrackFormat(0); String mime = format.getString(MediaFormat.KEY_MIME); Log.d("OUT", String.format("MIME TYPE: %s", mime)); extractor.selectTrack(0); return extractor; } 

Aquí está el registro.

¿Cómo debo solucionar este problema? ¿Qué es libwvm.so? ¿Por qué no se abre?

Aquí es cómo llamé a las funciones:

 public void start() { this.running = true; Log.d("OUT","start starts"); Log.d("OUT", file_in); Log.d("OUT", file_out); codec = configure_codec(); extractor = extract_video(); now_start(); }
