    Default unlocking videofiles for updating them (Windows 2008R2)

    Dear all,

    we have the recent wowza release running on windows 2008r2. Perfekt so far.

    But we have problems exchanging video files for updates. if the file is in use (being streamed), it is shared locked by the os.

    Do you have any clue how to copy a new version of a video file "over" the old one? we would accept killing the users stream.

    regards

    additional information:

    maybe this ist something for you at wowzamedia, what do you think?

    WORK AROUND

    For jdk7, the workaround is to use new file system API. So instead of new FileInputStream(f) and new FileOutputStream(f), use f.toPath().newInputStream() and f.toPath().newOutputStream().

    Richard,

    is there any chance in the near future, that you include the above mentioned new java file system API into Wowza Media Server? It would help a lot. Everyone running Wowza under Windows in a professional environment should have the problem exchanging files while they are in use.

    could you give us a perspectice?

    regards

    I have this same issue, although I generally chalked it up to bad implementation on my part (trying to overwrite files in use), but sometimes it certainly would be handy. For example, sometimes a speaker requests that we remove part of his recorded presentation -- right now, we have to manually stop the Wowza app or drop users to overwrite the original file. It would be nice if overwriting would simply interrupt users automatically, forcing them to reload to see the corrected video.

    Dear Richard,

    on 01-21-2013 I asked for help regarding "unlocking videofiles for updating them (Windows 2008R2)."

    On the same day I offered a solution, I found on bugs.sun.com

    Is there any chance, that you implement f.toPath().newInputStream() and f.toPath().newOutputStream() ? Or is there any argument against it?

    It would help a lot!


    Regards C. Fischer
