is that file playable using the DLL decoder? (-afm acm) if yes, then upload the file, and bugreport on ffmpeg-devel if not, then it's an encrypted asf/wma file, delete it or use windoze A'rpi / Astral & ESP-team -- Developer of MPlayer, the Movie Player for Linux - http://www.MPlayerHQ.hu

no way STFA the machine (actually the windows registry + DLL) where teh file was downloaded keeps the keys. there is a windows program able to decrypt it using teh windows dll... but don't ask to port it to linux, not possible, as the dll uses teh hardware parameters as key to crypt that, so unless you can do 100% emulation or rev. eng. the whole dll, you won't be able to do that... in short: fsck microsoft A'rpi / Astral & ESP-team -- Developer of MPlayer, the Movie Player for Linux - http://www.MPlayerHQ.hu

I was thinking more along the lines of brute force (or known plaintext?) cracking, or decrypting with a known key you pass on the command line, etc. Perhaps that's best done by a separate standalone program though. Rich
Arpi, I will try to play this file with the Windows Media Player under wine. We will will then know if the hardware thing is needed.

Hi,
[Automatic answer: RTFM (read DOCS, FAQ), also read DOCS/bugreports.html] Arpi, I will try to play this file with the Windows Media Player under wine. it won't work
it won't even work if you copy the file to another windows and try to play there. also won't work if you re-install the windows or change the hw. (it has the goal: copy protection) afaik, a special key is generated using windows serial (and other) numbers, hw parameters/numbers etc. then this key is somehow passed to the server and used to encrypt the file at server side. so only that machine will be able to play the file which downloaded it (after sending its own key to server). i'm not a crypto expert, i'm not even interested (and have big knowledge) on crypto stuff, but imho it's hard to crack. the only(?) simple way is writing an app which runs on teh same machine where you can play it, and "emulates wmp" using the same crypto DLLs and hw/registry/etc info, so it will get it decoded. there exists a such program, using portions of openssl for crypto stuff, and using the same DLLs (including that blackbox.dll) as used by wmp for key exchange. i don't remember the URL, but there was an article about it on register.com, about half year ago.

IMO, the best solution for fixing such files would be to make a wrapper dll for the WMA decoder DLL, and have it log the decrypted WMA stream to disk while it plays on the windoze system with the key. :)) Of course this is getting OT here... Rich

imho not really possible. there is DMO decoder for wma under win, and wmp 8/9 uses that dll for wma decoding. and DMO codecs uses auth/crypt of data between demuxer and codec, just to avoid 'sniffing the wire' or stoling the codec (remember div3).
Of course this is getting OT here... yes

Yes. He has. Or had. The Internal Affairs already apologised him for unlawful arrest on void charges. He was suing government on that ground last time I heard. The case against him finally had to be tried based on codes for ``breaking into computer systems'' clearly designed for busting on cracking into other people systems. The result of the case in Norway, which has explicit provisions for ``reverse engineering for interoperability'' is more than certain. And finally... Regardless of what's said above, one can sue whoever he wants for whatever he wants, right? In the end the one with longer penis^W^Wbetter and more expensive lawyers wins? Wrong, in most European countries the party that loses civil trial pays legal expenses of victor and court's expenses as well. That's the reason people don't sue everybody and their brother with hope of settlement outside of court here. Robert -- Bastard Operator From 149.156.96.35

I'm tired of stupid attitudes like this. Thats why I like projects like mplayer where people engage in what resembles civil disobedience, and find things like Linux where important features get left out to comply with the law "for the purpose of making a political statement about how stupid it is" disgusting.
