• 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 !

• FFMPEG : Position images in video when creating slide show

  29 décembre 2015, par Jimmy

  I’m using FFMPEG shell utility in an Android app to convert users pictures to video, here’s an example command :

  cat *.jpg | ffmpeg -f image2pipe -r 10  -vcodec mjpeg -i - -vcodec libx264 -s 1280x720 -preset ultrafast slideshow.mp4 

  I used to crop images when the user import it in the app but now I would like to allow the user to reposition the image later, here’s an example :

  

  So the user could drag or zoom the image to position it in the clear area (video ratio).

  So using the ffmpeg shell command can I specify the image coordinate for each image and position the image in the video.
