• avformat/http: check the auth string contents not the pointer which cannot be NULL

  14 octobre 2013, par Michael Niedermayer

  avformat/http: check the auth string contents not the pointer which cannot be NULL
  It appears this bug originates from a "work in progress" patch from
  
  ffmpeg-devel that was heavily redesigned by and integrated in libav
  And that patch even had a reply and review on the mailing list pointing
  
  out that it had a bug.
  This fixes a deadlock with ffserver
  See : [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
  
       [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036
  
       [FFmpeg-devel] [PATCH 2/3] Only add Transfer-Encoding header when not in authorization phase, because server will wait (indefinitely) for data when receiving this header Partial fix #3036
  
       [FFmpeg-devel] [PATCH 3/3] Only allow posting data and/or forcing a 200 code, enabling posting isml chunks, -after- we did a possible first request to get a 403 from the server telling us which type of authentication to apply Final part fix #3036

• FFMpeg command in android tutorial

  25 novembre 2013, par Azhagiri

  I want to write a android app that concats two videos

  i tried the following code

      InputStream in=null;
  
      OutputStream os=null;
  
      String appFileDirectory = getFilesDir().getPath();
  
      final String executableFilePath = appFileDirectory + "/ffmpeg";
  
      final String input ="concat:/mnt/sdcard/input1.mpg|/mnt/sdcrad/input2.mpg";
  
      File executable=new File(executableFilePath);
  
      try {
  
          in = getAssets().open("ffmpeg");
  
          os = new FileOutputStream(executable);
  
          int read = 0;
  
          byte[] bytes = new byte[1024];
  
  
  
          while ((read = in.read(bytes)) != -1) {
  
              os.write(bytes, 0, read);
  
          }
  
  
  
  
  
      } catch (IOException e) {
  
          // TODO Auto-generated catch block
  
          e.printStackTrace();
  
      }finally {
  
          if (in != null) {
  
              try {
  
                  in.close();
  
              } catch (IOException e) {
  
                  e.printStackTrace();
  
              }
  
          }
  
          if (os != null) {
  
              try {
  
                  // outputStream.flush();
  
                  os.close();
  
              } catch (IOException e) {
  
                  e.printStackTrace();
  
              }
  
          }
  
      }
  
      executable.setExecutable(true);
  
      Button b = (Button)findViewById(R.id.button);
  
      b.setOnClickListener(new View.OnClickListener() {
  
          @Override
  
          public void onClick(View view) {
  
              try {
  
                  Process p = Runtime.getRuntime().exec(executableFilePath + "-i \""+ input + "\" -c copy /mnt/sdcrd/output.mpg");
  
              } catch (IOException e) {
  
                  // TODO Auto-generated catch block
  
                  e.printStackTrace();
  
              }
  
          }
  
      });
  
  
  
  }

  this code doesn't give any error or it is not crashing but nothing happens when i click the button. I created the ffmpeg build that is compatible with android. So can anyone help me out how to run the command from android java code.

• rtmpproto : Move the flv header/trailer addition to append_flv_data

  3 octobre 2013, par Martin Storsjö

  rtmpproto : Move the flv header/trailer addition to append_flv_data
  update_offset is also called from handle_metadata, where the
  
  packet header sizes is already included in the size.
  Previously this lead to flv_data/flv_size including 15 uninitialized
  
  bytes at the end after each call to handle_metadata, making the
  
  flv demuxer lose sync with the stream.
  Also remove leftover copying in handle_metadata. This is a leftover
  
  from the refactoring in 5840473. (Previously this final mempcy was
  
  the one that copied all the packets at once, while this is done
  
  within the loop right now.) After making sure flv_size is set to
  
  the right size, this write was out of bounds.
