CCN-VLC-AccessModule

The CCN 1.0 version of the VLC access module that enables streaming of movies over CCN

This code was tested against the VLC-2.1.6 [1] using gcc-4.8 and g++-4.8. Using significantly later versions (e.g. 2.2.4) will cause compile errors, as there were VLC API changes (and it also requires gcc-5).

You should generally follow the instructions in src/README.install. The differences are:

  • Use VLC-2.1.6 [1].
  • You may use the Athena forwarder, rather than metis. Either should work.
  • Use CCNx_Distillery/usr/bin/ccnxSimpleFileTransfer_Server instead of CCN-Tutorial-Demo and tutorial_Server.
  • Use "ccnx:" everywhere instead of "lci:" in URI.
  • The instruction on how to use ln -s was incorrect and causes a bad link to be placed in the VLC plugin/access directory. Please remove the bad link and use the updated command ln -s /home/USERNAME/CCN-VLC-AccessModule/src/libaccess_ccn_plugin.so /home/USERNAME/VLC-Built/lib/vlc/plugins/access/libaccess_ccn_plugin.so

To use ccnxSimpleFileTransfer_Server:

  • Compile CCNx_Distillery following its instructions.
  • Create a directory with a movie in it, e.g. BigBuckBunny [2].
  • Start the server (after metis or athena). Note that the VLC plugin hard-codes the namespace ccnx:/ccnx/tutorial so we need to use that.
USERNAME@sautte:~$ CCNx_Distillery/usr/bin/ccnxSimpleFileTransfer_Server -l ccnx:/ccnx/tutorial -s 1200 ~/movies
Server Configuration: 
  namePrefix:    [ccnx:/ccnx/tutorial]
  doPreChunk:    [false]
  directoryPath: [/home/USERNAME/movies]
  chunkSize:     [1200]
  beVerbose:     [false]
ccnxSimpleFileTransfer_Server: now serving files from /home/USERNAME/movies
  • In a new terminal, verify the server is operating:
USERNAME@sautte:~$ ./CCNx_Distillery/usr/bin/ccnxSimpleFileTransfer_Client -l ccnx:/ccnx/tutorial list
Client Configuration: 
  namePrefix:    [ccnx:/ccnx/tutorial]
  doSaveToDisk:  [true]
  beVerbose:     [false]

  Command: [list] []

Directory Listing follows:
  BigBuckBunny_320x180.mp4  (64657027 bytes)
45 bytes transferred in 8 ms (0.005 MB/sec)
  • You can then try the VLC plugin:
VLC-Built/bin/vlc ccnx://BigBuckBunny_320x180.mp4

NOTE: You must use two "//" forward slashes here, otherwise VLC will try to use a local file path.

  • If you have problems, try running metis with debugging: CCNx_Distillery/usr/bin/metis_daemon --log processor=debug and it will show you the URI names in the Interest messages.
