clip length |
|
|
Is there any way to know the duration of a clip without setting the Windows Media Player's src to the clip?
I have a stack of clips (~400) to deal with, and I'd like to batch process grabbing the duration. However, I think if I just kept setting the embedding video object's source and writing the length to file, it would crash pretty quickly, and take forever to complete.
Anyone have any ideas?

Not without examining the file headers - you'd need I think the WM
Format SDK available to read the file headers, the WMP SDK doesn't
have this functionality without instantiating the player.

Ive done it, it's not so bad - not quick mind, but doesn't crash
either ;-) |

How would it work with the SDK?

Any name of a utility? metadataedit, wmstats and wmvedit don't have that
ability, and besides those I can only see source-code-sample-only tools to
do so.

Try 4000 clips with each length of about 5 to 10 seconds. :-)

Well as I said I can't think of anything : the WMProp console app
might be adaptable (from the format SDK), but I've not used it :
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmform95/htm/sampleapplications.asp
There *are* standalone apps to read this stuff I've seen, but they're
not batchable like you would do with VDub or other software. For
example Sliq do the "WMSnoop" tool currently available for free
download : http://www.sliq.com/default.asp?view=wmsnoop

Hah, don't be such a girl, just get a faster PC ;-)
I guess it depends if the OP has a job which is a one-off and he needs
to process the 400 files once, or if it's a job which needs doing once
an hour. He didn't say.

Huh? The problem is that is simply hangs up because of bugs.
However, one could imagine to use "start utility params" as long as no-one
is working on the machine, so one bad file / error condition doesn't stop
the entire progress.

No, that's not the problem. The OP said and I quote :
"However, I think .... it would crash pretty quickly, and take
forever to complete" : He's saying he hasn't tried it, and I'd agree
it would take forever to complete. Bugs or no bugs, it's not my
experience that a crash is predicated on loading 400 (or 4000) files.

No, you'd use "try ... catch" blocks so that one error condition
results in the loop body being skipped.

Seems to me the best way to do this is to build something server side, like
a web page you could hit that would run a utility to look at the files and
return the clip lengths.
Thanks,
Bill
