• Path to publish FFMPEG video files to Azure Blob Storage ?

  25 janvier 2016, par CG-Guy

  Please kindly help me get out of a bad situation with a very very unhappy client. I am using FFMPEG based app to publish video files to Azure Blob storage, but the files are not going through the network. FFMPEG app has full access to firewall ports. FFMPEG communication shell show files are published without errors. A look at TCP connections shows the app is making connection with Azure account remote address 104.208.XXX.XX and remote port 443. However, it drops the connection and starts repeating attempts over and over. It will then time out after countless attempts and crash the app. Here is my publish point. Is this the correct publish point for this kind of connection ? What is the proper connection string ? :

  https://account-name.blob.core.windows.net/video/video.flv /DestKey :account-storage-key

  I have also tried http:// without success. Same thing happens. It attempts connecting to remote address and port 80. Again, after several attempts it will timeout and crash. System is a Server 2008 R2 unit on-site, not VM. Your help is much appreciated. Thanks a lot !

• How to upload files to Azure Blob Stotage like FTP ?

  25 janvier 2016, par CG-Guy

  I am able to upload files from my ffmpeg app to an FTP using this path :

  ftp://[user:password]@server[:port]/MyFolder/video/video.flv

  How do I achieve the same thing in Azure Blob ? I have tried this path :

  https://[account-name].blob.core.windows.net/video/video.flv /DestKey:[account-storage-key]

  But that doesn’t seem to work. TCP connection shows the app is making a connection with the Azure account to the remote address 104.208.XXX.XX and remote port 443. However, it drops the connection and starts attempts to reconnect repeatedly. It will then time out after countless attempts and crash the app. I have also tried /> without success. The same thing happens. It attempts connecting to the remote address and port 80.

  The FFMPEG app has full access to firewall ports and the app communication shell show files are published without errors. System is a Server 2008 R2 unit on-site, not VM.

• ffmpeg convert any file to any file

  28 mai 2015, par Vishnu

  I Want simple command to convert any supported file to any file with little possible video compression.

  for example

  avi to mp4
  
  mp4 to 3gp
  
  .
  
  .etc..

  I tried below code

  ffmpeg -i infile.flv outfile.3gp

  It works for some but for some other like flv to 3gp conversion it throws error like below and also output file size is very large than input.

  "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height" 

  P:s i compiled with below librareis

  ./configure --enable-version3 --enable-libopencore-amrnb --enable-libvo-aacenc --enable-libopencore-amrwb --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-gpl --enable-postproc --enable-nonfree
