URL-Problem

[Christian Marsch]

Hi

I am using FOBS4JMF for a video-player (only videos, no sound) based on JMF.

the player should be able to take screenshots and save them as a picture while playing, which works quite well.

there are problems if a filename (and the generated URL)
-is not located on local drive (netpath)
-contains german umlauts (like ä ö ü)
-contains space characters

the player works in that way:
get a file, get its URL and create a processor.

first i was using file.toURI().toURL(). when using file.toURL() the player could play filenames containing space-characters.
this seems to be because the space chars are not replaced by %20.
not a nice workaround but it works. the other two problems stay.
the funny thing is that in JMstudio it works, when using a realized player it works to. When creating a processor i get the following:

Code for producing the file open error:

try {
    p = Manager.createProcessor(ml);
} catch (Exception e) {
    p = null;
    return false;
}

a more detailed view of the code can be found here (my program is based on this):

I am using
JRE 1.6. Update 3 (same goes with Update 6 or 7)
FOBS4JMF 0.4.2
Windows XP (SP3) , same could be reproduced on VISTA
the movie could be MPEG2 or even MPEG4

My question is:
is there any workaround for this or any other way
to get a valid URL out of a filename?

Thanks for reply,

Christian

HI,

I have also encountered this issue.
It seems that file.toURI().toURL does not work correctly.

Try to create your URL using rather:

String filePath = file.getPath();

      URL myUrl=new URL("file:/"+filePath);
      p = Manager.createProcessor(myUrl);

I have the same error :
With jmf alone I can open a file located like that :
"D:/vidéos/test.mov";
but using fobs I cannot use an URL with accents.
Is there any solution to use FOBS4JMF with URL with accent like é,à,è…?
Thanks a lot.
