• Is there an effective and cheap/free way to host video for a mobile app that must be approved by an admin before going live ? [on hold]

  9 août 2013, par user2658775

  We are building a mobile app for the iOS and Android operating systems. The app is to be a communication platform for members within an organization. Content is generated by users and submitted to the admin. Once approved by the admin the content is pushed to the app. One feature of the app is the ability to upload video.

  We are having a tough time attempting to figure out the best way to do this. Because the app will be representing the organization, the organization must have control over the approval process.

  So far we have come up with the following options :

  Option 1 : purchase a dedicated server from hosting service provider. The basic package with Blue host is $150/month which is fairly expensive.

  Option 2 : have the users post to YouTube using their personal accounts. Upon posting to YouTube (via the app) the app would send a notification to the admin that a new video has been posted. Admin would review the video and if acceptable admin would user url link to post video to app. This option, while free, requires many steps that will bog down the submittal process.

  Does anyone know of an effective way to post video to an app that requires approval by an admin ?

• Stream video from mobile camera to ffmpeg with NDK

  19 juillet 2013, par user2598307

  I need to create an application that captures video from a camera phone and send it to ffmpeg. Everything should be done only NDK level without SDK and Java
   The phone can be Root

  I am trying to open camera on my android device with this function "avformat_open_input()". I give this function a reference to device folder "/dev/msm_camera/" or "/dev/video0".

  I try like this :

        void Java_com_example_camera_MainActivity_testVideo(JNIEnv *env, jclass jc, jstring *filename)
  
  {
  
          av_register_all();
  
          avcodec_register_all();
  
          avformat_network_init();
  
          AVFormatContext* context = avformat_alloc_context();
  
          int video_stream_index,ret,i;
  
          AVInputFormat *input_format = NULL;
  
          const char formatName[] = "mpeg"; //for example mpeg
  
          const jbyte *str;
  
          str = (*env)->GetStringUTFChars(env, filename, NULL); //filename = "/dev/msm_camera"
  
          input_format = av_find_input_format(formatName);
  
          ret = avformat_open_input(&context, str, input_format, NULL);
  
          if (ret < 0){
  
             LOGE("Not open");
  
          }else{
  
             LOGI("camera was open");
  
          }
  
          if(avformat_find_stream_info(context,NULL) < 0){
  
             LOGE("No stream");
  
          }
  
          for(i =0;inb_streams;i++){
  
             if(context->streams[i]->codec->codec_type == AVMEDIA_TYPE_VIDEO)
  
                 video_stream_index = i;
  
          }
  
          AVPacket packet;
  
          AVFrame *pFrame;
  
          av_init_packet(&packet);
  
          pFrame = avcodec_alloc_frame();
  
  
  
                  //open output file
  
          AVOutputFormat* fmt = av_guess_format("avi", NULL, NULL);
  
          AVFormatContext* outputContext = avformat_alloc_context();
  
          outputContext->oformat = fmt;
  
          avio_open2(&outputContext->pb, "/sdcard/test.avi", AVIO_FLAG_WRITE,NULL,NULL);
  
          AVStream* stream=NULL;
  
          AVFrame * frame;
  
          frame = avcodec_alloc_frame();
  
          int cnt = 0, frameDecoded;
  
  
  
                  //start reading packets from stream and write them to file
  
          av_read_play(context);
  
          while(av_read_frame(context,&packet)>=0 && cnt <300){ //Here function return -1
  
            if(packet.stream_index == video_stream_index)
  
            {//packet is video
  
              if(stream == NULL){
  
                 //create stream in file
  
                       stream = avformat_new_stream(outputContext,context->streams[video_stream_index]->codec->codec);
  
                       avcodec_copy_context(stream->codec,context->streams[video_stream_index]->codec);
  
                       stream->sample_aspect_ratio = context->streams[video_stream_index]->codec->sample_aspect_ratio;
  
                       avformat_write_header(outputContext,NULL);
  
               }
  
               packet.stream_index = stream->id;
  
               av_write_frame(outputContext,&packet);
  
               cnt++;
  
             }
  
             av_free_packet(&packet);
  
             av_init_packet(&packet);
  
          }
  
          av_read_pause(context);
  
          av_write_trailer(outputContext);
  
          avio_close(outputContext->pb);
  
          avformat_free_context(outputContext);         
  
   }

  As I know, we cannot get access to camera because my program has not root permission. So how I can give my program root permission ? Or how I can go around this problem ?

  I also tried to interact with the device driver using ioctl commands on C\C++, but I did not succeed because I have no experience and examples in Google.

  Thank you !!!
