    1919== When to produce VOB files [Resolved] == 
    2020 
    21 Raised by GM - 2010-08-02 
     21Raised by GM - 2010-08-02 - Resolved, then revised as the prototype was created & information provided by ch.psal 
    2222 
    23  * The current design has the transcode daemon system producing VOB files for every video in a Plumi system 
     23 * The original design has the transcode daemon system producing VOB files for every video in a Plumi system 
    2424 * The benefit of doing this is that it means that when a DVD ISO is being assembled by the Burnstation system, there's no need to encode VOBs, making it faster. 
    2525 * The problems with this approach are: 
     
    2828  * If the eventual system is to produce DVDs or VCDs, will VOBs be suitable for a VCD ISO? (see issue above re: prototype producing VCDs as well as DVDs) 
    2929 
    30 '''Decision made''' by Unweb & agreed by EM: Prototype will produce VOB files of all videos as space will not be an issue for prototype systems running in test environments. 
     30It was decided that the prototype would produce VOB files of all videos as space will not be an issue for prototype systems running in test environments.

    32 NOTE: Need to review this in final system design as if Burnstation is deployed on a large production site, space requirements for transcoded videos will increase significantly. 
     32Following development, the process was revised to: 
     33 
     34 1. Transcodedaemon creates an mpeg2 encoded version of all videos loaded into a Plumi system running Burnstation 
     35 1. When the burn process is started, system will create the VOBs (& other files) directly from the mpeg2 files (VOBs are based on mpeg2 encoded files) 
     36 1. Create the ISO of the DVD from the VOBs, BUPs and IFOs created in the step above 
     37 1. Serve the ISO to the user for downloading & burning 
     38 
     39NOTE: Need to confirm that if Burnstation is deployed on a large production site, space requirements for transcoded videos will not increase significantly.

    4047 * If not, how we will verify that the prototype is working correctly? On demo.plumi.org?

     49UPDATE: 2010-08-30 - Setting up Burnstation initially on testing.plumi.org for initial acceptance & verification.
