  • Progress Bar findviewbyid returns null

    1er avril 2017, par ziad kiwan

    Help me please it’s getting frustrating !

    i’m doing a chat application where i’m adding views to a linear layout programmatically each time a user press the send button the code is below :

    public  void appendToMessageHistory(String id,String uname, String messa,String messageType, final String filepath, String DownloadStatus,boolean internet,int type) {


       //TextView tv=new TextView(Messaging.this);
       LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(Width, LinearLayout.LayoutParams.WRAP_CONTENT);
       lp.setMargins(0, 10, 0, 0);

       View v = getLayoutInflater().inflate(R.layout.message_entity, null);


       TextView mess;
       TextView time;
       final ImageView iv;
       final ProgressBar progressBar;
       ImageView statusiv;
       if (friend.userName.equals(uname)) {

    okay now to the problem when i call the findviewbyid for the progress bar in sendvideomessage ffmpeg onsuccess callback it returns null even though the findviewbyid for the the imageview which is in the same layout it returns the view ! so please tell me what is the problem

    public void onSuccess(String message1) {
                   Log.w("Zipping","Success");
                   RelativeLayout v = (RelativeLayout) mEssageBox.findViewById(rowid.intValue()); ;

                   ImageView iv = (ImageView) v.findViewById(R.id.message_entity_right_imageview); // returns the view
               //  progressBar.setVisibility(View.GONE);
                   Bitmap bitTh = ThumbnailUtils.createVideoThumbnail(ZippedVideoPath, MediaStore.Images.Thumbnails.MINI_KIND);
                   iv.setImageBitmap(bitTh);
                   progressBar.setVisibility(View.GONE);
                   iv.setOnClickListener(new OnClickListener() {

  • av_video_decode2 RETURNS THE VALUE -1094995529 in the threaded function

    24 mai 2014, par Whoami

    I am developing rtsp streaming player, and followed the below approach.

    1) Read packet, decode, display -> works perfectly.

    while (1) {
       if ( av_read_frame(pFormatCtx, &amp;packet) >= 0) {
           if (packet.stream_index == videoStream) {
               retDecoder = avcodec_decode_video2(pCodecCtx, pFrame, &amp;frameFinished, &amp;packet);
               if  ( retDecoder &lt;= 0)
                   LOGD (" Unable to Decode...retval %d ", retDecoder);
               if (frameFinished) {
               }
           }
           av_free_packet (&amp;packet);
       }
    }

    Whereas,

    I introduced two threads, one is reading and pushing into the queue and the second one is reading from the queue.

    My problem is while reading the same packet, and decode, i m unable to decode, the return value of the av_video_decode2 is -1094995529.

    Below is the short description of code. Kindly help to solve this issue ?.

    AVPacketList *firstNode=NULL, *lastNode=NULL;

    int pushPacket (AVPacket * pkt)
    {
       AVPacketList *newNode = av_malloc(sizeof(AVPacketList));
       newNode->pkt = *pkt;
       newNode->next = NULL;

       SDL_LockMutex (rwMutex);

       if (lastNode != NULL )  {
           lastNode->next = newNode;
           lastNode = newNode;
       } else {
           firstNode = lastNode = newNode;
       }

    SDL_UnlockMutex (rwMutex);
    }

    int pullPacket ()
    {
       AVPacketList *tempNode;
       AVPacket *pkt;
       int res=0;

       SDL_LockMutex (rwMutex);
       if ( firstNode != NULL ) {
           tempNode = firstNode;
           *pkt = tempNode->pkt;
           res = avcodec_decode_video2(pCodecCtx, pFrame, &amp;frameFinished, pkt);  // HERE IS THE PROBLEM.
           if (frameFinished) {
               LOGD (" fRAME DECODED.. %d \n", counter++);
           }

           if (firstNode->next != NULL) {  
               firstNode = firstNode->next;
           }
           else {
               firstNode = NULL;
               lastNode = NULL;
           }
           av_free (tempNode);
       }
    }

    In Thread 1 :

    int PacketReader (void *ptr)
    {
       AVPacket pkt1, *rpacket;
       rpacket = &amp;pkt1;
       while (globalQuit != 0)  {
           if ( av_read_frame(pFormatCtx, rpacket) >= 0) {
               if (packet.stream_index == videoStream) {
                   pushPacket (rpacket);
               }
               av_free_packet(rpacket);
           }
       }
    }

    In thread 2 :

    while (1) {
      pullPacket ();
    }
