[AG-DEV] resurrecting AGVCRtoMPEG2

Hi,
I was working on a project called ViCoVRE which was involved in much the same sort of thing - i.e. taking AG recordings and converting them into other formats.
The project is currently hosted at:
http://vicovre.googlecode.com
There is quite a lot of code in there that will probably do what you want. It is in Java, but makes use of native ffmpeg libraries to do the actual conversion. Feel free to have a look and let me know if you have any questions. I think that the main thing that is missing is a reader for the AGVCR format (it uses its own AG recording format), although there is support for writing AGVCR files. It is also mainly web-based, so I would guess it might need a GUI if you prefer stand-alone execution. At worst, it might give you some hints for your own code ;)
Hope this is useful,
Andrew :)

Hi all
AGVCRtoMPEG2 converts AGVCR recordings to something more useful for playback eg mpeg2 and mp3.
so far the project was abandon 5 years ago https://trac.ci.uchicago.edu/if-media/browser/AGVCRToMPEG2
the code for 5 years ago successfully can extract h261 and audio and produce mpeg2 and mp3's.
I tracked the name of the orginal dev Yifan Lu but it seems he's to have moved on.
In my efforts to understand it a bit better I've run the source through doxygen to get call graphs and a understanding of flow.
http://noronha.id.au/AGVCRToMPEG2/files.html
I've noticed he's copied code from VPC project and VPMedia but then deleted stuff. Is their any active documentation for those projects ? and is any active devs out their able to tell me if the new code will just copy and paste in ?
currently waiting on uchicargo to give me svn access to upload any changes their is already a patch to allow it to compile with newer gcc and some new ubuntu install instructions. 11.04
plans just so you know: (in order sorta)
full codec support h264 h261as and mpeg4
different arrangements for videos 1 large rest small etc..
update to use new ffmpeg functions so not using superseeded functions.
64 bit support
GPU accelerated (dreaming)
new UI (maybe)
yours
