FxPlugWrapper uuids: _ vs. -

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hello all, I have an FxPlug effect that I am looking at in an XML exported from FCP. Its effect id looks like this: <effectid>FxPlugWrapper:744E7D2B_F361_4FA7_9DC7_83720F463C98</effectid> However, in the info.plist for the FxPlug I specify this uuid: D750D5F0-A2CA-4273-8F77-1AC84F132A82 The difference is that my - turn into _ in the XML. This is not really a problem, but somewhat unexpected. Is this the way it's supposed to behave? In my XML processing I am now relying on seeing _ in the effectid, so I don't think I am asking for this to change.

Re: drawing in an FXPlug Filter

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Thanks, Darrin, that's good to know. Always helps to get re-assurance when you're shooting in the dark... Just tried the first way - re-setting dataPtrs, that yields a black image in software render in FCP (that's all I am interested in anyways), for whatever that's worth. So, the second way it is!

Unfortunately, the first way will likely get you into big trouble. In Motion, at least, the app owns the data for the input and output images, and knows when it can dispose of each.

Yes, it's convoluted and slower, but we don't have a mechanism that says, "This plug-in can operate in-place." That might be really handy some day. Most of the color correction filters (in fact, anything pixel independent) should theoretically be able to do that. (I'm not sure how OpenGL would handle that in hardware, though. I think I just might have to ask the OpenGL folks about that!)

Re: API for Accessing FCP Session files?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi Tim, The Final Cut project file format is not documented. Exporting to XML is the way to get a readable representation of what's in the project. You can send FCP an Apple Event that will return the XML data, if you want to avoid having the user manually export XML. But FCP must be running for this to work.

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Bump - I can't tell if this actually got posted to the list previously. Hi Folks, I've been digging through the documentation that I can find, but I haven't found an answer to the question of if there is an API available for accessing FCP session files. I'd like to be able to more elegantly parse a session file to determine the actual disk files used in the project. Is there a C/Obj-C or Applescript API that I could call into play?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Oh, now that you put it in those terms, this is ringing some distant bell in my head. If they're using ftp for the transfer, then it could be that most ftp clients won't give you the progress info, or you can't guarantee that you'll be able to get it, or something along those lines. I'm totally speculating on that, but I have this vague memory of that being a stupidly difficult thing to get out of ftp (and probably some other protocols, too).

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com This info does not seem to be tracked by Final Cut Server. If you open other types of jobs in Search All Jobs you can see the progress as a percentage, but it remains at 0 for uploads. In the Administration Log, it shows that it is in RUN status but no progress is reported. You can confirm it by checking /Library/Logs/Final Cut Server/fcsvr_stored_XXXX.log, which shows for every upload log entry progress=0 and PROGRESS = -1 I guess this is because Final Cut Server (the server) doesn't know the progress - only the client knows. You may want to file a bug/feature request, or post to the Final Cut Server group at discussions.apple.com to see if other people have workarounds for whatever you're trying to do. -- john f whitehead / +1 646 320 3727 / jfw(a)mediaflowdesign.com / www.mediaflowdesign.com On Mar 14, 2011, at 21:22, Darrin Cardani wrote: > > On Mar 10, 2011, at 8:49 AM, Michael DeMattia wrote: > >> Is there a way to see real data when uploading files to final cut server? >> >> Right now is there only a blue bar for status >> >> I would love the ability to see how much data has been sent or how much time is left >> >> Any idea would be great > > I asked someone from the FCS team, but have not gotten a response.
