• Playing RTSP stream in Android

  9 décembre 2014, par Kamil

  I’m trying to play video stream on Android device. Unfortunatelly I still get the same problem with MediaPlayer/VideoView. I’m searching for a few days, but still haven’t found any working solution.
  For test purposes I’m using MediaPlayer app from API Demos (API Demos/Media/MediaPlayer/Play Streaming Video).
  Here is code snippet for playing stream

  mMediaPlayer = new MediaPlayer();
  
  mMediaPlayer.setDataSource(path);
  
  mMediaPlayer.setDisplay(holder);
  
  mMediaPlayer.prepare();
  
  mMediaPlayer.setOnBufferingUpdateListener(this);
  
  mMediaPlayer.setOnCompletionListener(this);
  
  mMediaPlayer.setOnPreparedListener(this);
  
  mMediaPlayer.setOnVideoSizeChangedListener(this);

  When I try to play stream I get this info from logcat
  http://pastebin.com/5Uib5CH5

  This is configuration of ffserver streaming the video

  Port 8090
  
  BindAddress 0.0.0.0

  If anyone can advise me how to fix it, or at least indicate an mistake, I will be grateful.

• tips needed : aac encode on android using ffmpeg-neon optimization

  13 octobre 2011, par user992537

  there
  I am trying to do some performance improvement about libfaac/libx264 encoder using ffmpeg and neon.seems successfully compiled ffmpeg with neon support,and video encode performance indeed has some improvement,however when it comes to aac encode, it barely can run...Do I have to do some code change about aac specificly ? Does this have something to do with neon`s fft stuff ?Totally clueless, any tips would be greatly appreciated !Thanks

• Encoding Raw PCM data to AAC using ffmpeg in Android

  10 janvier 2012, par NISHAnT

  Now, i m using libfaac directly to convert raw PCM data to AAC in JNI. Frames Encoded successfully still bytesWritten is always 0 it means there will b some problem in code Here is my Code.

  JNIEXPORT
  
  jbyteArray JNICALL Java_com_encodePCMFrame(JNIEnv * env,
  
      jclass clazz,short* data,jint bitRate,jint sampleSize,jint channelConfig)
  
  {
  
  
  
  
  
    faacEncHandle hEncoder;
  
      unsigned long samplesInput, maxBytesOutput, totalBytesWritten;
  
      faacEncConfigurationPtr faacPtr;
  
      char *faac_id_string;
  
      char *faac_copyright_string;
  
      unsigned long inputsamples;
  
      unsigned long maxoutputbytes;
  
      unsigned char* bitbuf;
  
      int bytesWritten;
  
      jbyteArray AACframe;
  
      jsize size;
  
  
  
  
  
      if(faacEncGetVersion(&faac_id_string, &faac_copyright_string) == FAAC_CFG_VERSION)
  
      {
  
        __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "\nFAAC_ID_STRING %s\n\n ", faac_id_string);
  
      }
  
  
  
  
  
      hEncoder = faacEncOpen(sampleSize, channelConfig,&inputsamples, &maxoutputbytes);
  
  
  
      if(hEncoder)
  
      {
  
         __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "AAC Codec Open (samplesize = %d)\n (channelConfig = %d)\n (input Samples = %d)\n(Max OUTPUT BYTES = %d)\n (bitRate = %d)...",sampleSize,channelConfig,inputsamples,maxoutputbytes,bitRate);
  
      }
  
  
  
  
  
      faacPtr = faacEncGetCurrentConfiguration(hEncoder);
  
  
  
      faacPtr->aacObjectType = MAIN;
  
      faacPtr->mpegVersion = MPEG2;
  
      faacPtr->outputFormat = 1; //ADTS
  
      faacPtr->bitRate = bitRate;
  
      faacPtr->inputFormat = FAAC_INPUT_16BIT;
  
  
  
  
  
  
  
      if (faacEncSetConfiguration(hEncoder, faacPtr)==0)
  
      {
  
           __android_log_print(ANDROID_LOG_VERBOSE, APPNAME,"fail to set");
  
           faacEncClose ( hEncoder );
  
           hEncoder =0;
  
      }
  
  
  
  
  
  
  
          bitbuf = (unsigned char*)malloc(maxoutputbytes*sizeof(unsigned char));
  
  
  
         bytesWritten = faacEncEncode(hEncoder,(int32_t *)data,inputsamples,bitbuf,maxoutputbytes);
  
  
  
  
  
      if(bytesWritten<=0)
  
      {
  
              __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "Can Not Encode Frame... bytesWritten = %d ",bytesWritten);
  
              faacEncClose(hEncoder);
  
      }
  
      else
  
      {
  
             __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "Bytes Written = %d ",bytesWritten);
  
  
  
             __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "Encoding frame %d ",bitbuf);
  
      }
  
  
  
  
  
      AACframe = (*env)->NewByteArray(env,maxoutputbytes);
  
  
  
      (*env)->SetByteArrayRegion(env,AACframe, 0,maxoutputbytes, bitbuf);
  
  
  
      __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "Buffer AAC Frame == %d    Allocated...  Size == %d ",AACframe,maxoutputbytes);
  
  
  
  
  
      return AACframe;
  
  
  
      av_free(bitbuf);
  
      av_free(data);
  
      (*env)->ReleaseByteArrayElements(env, AACframe, 0, JNI_ABORT);
  
  
  
   }

  Thanks in Advance.
