• hwcontext_vdpau : implement av_hwdevice_get_hwframe_constraints()

  hwcontext_vdpau : implement av_hwdevice_get_hwframe_constraints()
  In addition, this does not allow creating frames contexts with sw_format
  
  for which no known transfer formats exist. In theory, we should check
  
  whether the chroma format (i.e. the sw_format) is supported at all by
  
  the vdpau driver, but checking for transfer formats has the same effect.
  Note that the pre-existing code adds 1 to priv->nb_pix_fmts[i] for
  
  unknown reason, and some checks need to account for that to check for
  
  empty lists. They are not off-by-one errors.

• 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 !

• Xuggle build failed on ubuntu x64 ?

  3 avril 2012, par beginner

  After downloading the source code from GIT hub I setup the enviroment variables
  as Xuggle YouTube Video said so

     export XUGGLE_HOME=/usr/local
  
     export PATH=$XUGGLE_HOME/bin:$PATH
  
     export LD_LIBRARY_PATH=$XUGGLE_HOME

  Then I simply started the ant test by command

  ant run-tests

  Which gave me following output with error in the end ..
