Created because I can't keep up with all the threads discussing
iPlayer hacks on the various sites and forums. I've filled out quite a
bit on the iPlayer already but it could do with more info and there
are stubs for other BBC services there as well.

I think I entirely misunderstood what the point of this mailing list
was. I was encouraged to come here to discuss running the iPlayer on
exotic platforms but now we're actually doing it it seems it's a taboo
subject. Rather than try and work out the bizarre politics of this
place I'll be writing my main discoveries regarding the iPlayer on the
wiki, which is Free (in both regards).

Re: [backstage] iPlayer DRM is over?

2008-03-18 Thread vijay chopra
To play devils advocate:
I don't think it's the politics. From what I understand through recent
discussions on and off list, it's more to do with (as always) keeping
rights' holders happy.
I think that the actual BBC staff would love to hear the various hacks that
people here come up with (be prepared for them checking your wiki), but when
those hacks bypass content protection measures, it puts them in the awkward
position of telling the rights' holders that iPlayer is secure, whilst at
the same time hosting a list detailing how to get around that security.
So go ahead and post iPlayer hacks on this list, just leave the various
forms of DRM in place.
I'm not saying I totally agree with this stance, just explaining it, and
noting that I understand it.

Vijay.

Two scenarios:

Scenario 1:

Guy knocks on your door, walks in past you, urinates on your best rug on the
floor, then hands you a note saying your house smells of piss and walks out.

Scenario 2:

Guy knocks on your door, walks in past you,  hands you a note saying go this
website to read a report on how someone urinating on your best rug can make
your house smells of piss and walks out.

Question: which scenario appeals to you? Note - remembering that the rug
really tied the room together.

I doubt many people on here would put up with a premoderated list, and
for the bbc I imagine it might be financially crippling to employ
someone to premoderate a High Volume mailing list like this.

So you are suggesting this list engages in Self-Censorship so that the
BBC can give the impression that it knows that the iplayer DRM schemes
are:
a) broken
b) pointless
c) designed in a defective manner ;)

I think it would be good to let bbc-backstage know at regular
intervals exactly what the status of the bbc-iplayer drm is.

How broken is it at the moment?

Most of what is on that wiki should be on the Backstage site as  
documentation. There's not enough documentation on what's available  
and how it works. (Although to be fair I'm sure a lot of this isn't  
very well documented internally either ;-)


However it was made very clear from the start that the only thing  
that those discussing iPlayer couldn't do was try to break any  
protections on the content. That's what is causing the problems on  
the list and the only thing on the wiki that is contentious.


(All my personal opinion of course).

Maybe you should explain it to them?

Trying to remove information from the Internet tends to have opposite effect.
Remember when someone tried to remove the HD-DVD encryption key from
the internet[1], how may websites, emails, T-shirts etc. is that
number on now?
Remember recently a US court tried to take down wikileaks, any idea
how may mirrors now hold those files?

Oddly publicity of this information *increased* when people tried to
have it removed.

Would it not be better to invest in proper security?

(A bit of free advise was provided earlier, however from what I have
just read it appears you are making the same mistakes again, if your
engineers are literate, go buy a book on security and look up the term
"Replay Attack" )

I was invited onto this list by a member of Backstage staff who said
that it was a good place to discuss the iPlayer and hacking it to work
on exotic devices, and that's what I've done.

I'm lost as to how this is analogous to knocking on someone's door and

It strikes me as closer to reverse engineering to create interoperable
clients myself, to be frank.

After all, it's a publically funded service which people who have paid for it 
are trying to access - we've never stopped our audience building their own 
recievers - where possible - in the past. Indeed, for Digital Radio Mondiale 
(the other DRM :), it can be fairly common).

[backstage] Google Summer of Code 2008

2008-03-18 Thread Michael
Hi,


This just a short note to say that BBC Research has been accepted as a mentor 
organisation for Google Summer of Code again this year (third year!). Also 
Dirac applied seperately along with the Schroedinger project and as a result 
dirac/schroedinger is also a mentor organisation this year.

As a result, if there's any students on the list who are interested in working 
on something that scratches their itch, and matches the goals of  Kamaelia, 
Dirac, Schroedinger - or any other BBC open source project, please do get in 
touch.

If you're a BBC person who happens to runs or works with a BBC open source
project, and I don't know you and haven't reached you by any other mechanism
and you're interested in mentoring a GSOC Project, please get in touch with
me.

Dirac/Schroedinger's list is here:
http://www.diracvideo.org/wiki/GSoC2008Ideas

Kamaelia's list is here:
http://kamaelia.sourceforge.net/SummerOfCode2008


If you have some interesting ideas for projects (with the caveat that they 
must fit with a BBC open source project) that you can't do for whatever 
reason, please let us know - we'll happily add that to the list of ideas.  
(Can't guarantee it'll get worked on for two reasons : 1) projects are 
proposed by students and accepted/rejected by orgs. 2) there's often many 
many more project proposals than slots)

Bonus points given to project ideas that support ongoing BBC work :-) (or work 
you'd like to see the BBC do :)

People can feel free to contact me off list. (Posting using home email because 
this'd bounce otherwise)

For BBC people lurking on the list that don't generally post...
   * Got an idea you want explored ?
   * Want to see a particular library integrated into Kamaelia? (thereby
  making it usable with everything else)
   * Would you like to mentor a project over the summer ? (The first users of
  Kamaelia didn't tell us until several months after they'd completed
  their project, so this doesn't seem to odd to ask here :)
   * Do you run an existing BBC Open Source project and do you have some
 low hanging but interesting fruit you'd like someone to work on?
   * The ideas on the kamaelia website are currently just of interest
 to me [1] but I can think of many many more, and really interested in
 full system ideas at the moment. The presentation on the the ideas
 page also covers 3 relatively interesting systems.
 [1] They're also targetted in such a way to drop out a significant
 chunk of useful components along the way, all of which would
  be reusable.

If so, please get in touch ASAP. I'll need your gmail account id. The more
we put into GSOC, the more students get out of it and the more we all get out 
of this. Also, many hands make light work, etc :)

Also, to be frank, I'd really like ideas of what you might think can be done 
if you combine a system that can have a built in webserver, with open GL, 
with SDL, Audio in, audio/video out, arbitrary transcoding muxing of DVB, Bit 
Torrent distribution, serving over multiple protocols (tcp/udp/multicast) all 
at once. (seriously, these can all be mixed and matched *pretty trivially* ) 
etc

Due to being written in python this allows us to pull in most C libraries 
fairly easily, and if someone can write a stub application that achieves the 
core of their problem, we can turn it into a component that can be used with 
anything else.

Due to some recent changes it'll also support multicore systems natively (ie 
use all the CPUs) with very light touch changes to top level code. (this is a 
bit experimental :)

Have fun!


Michael.

Oh, just a note - for those that don't realise what Google Summer of Code is - 
it's where google will happily pay someone in (or about to enter) higher 
education for work over the summer on open source projects. The results
are also open source.

Links: http://code.google.com/soc/2008/
  http://code.google.com/soc/2008/faqs.html

Specifically Google pay students $4500 over the course of the summer for
around 3 months full time work. Google also pay mentor orgs a small amount
per mentor, in the past the BBC's waived this for various good reasons. 

The whole idea is to get students involved in Open Source/Free Software during 
their vacations, which they might otherwise spend in a Summer job. For more 
information, please see the website. Overall it ends up being a 3 way win 
normally.

If you have any q's feel free to mail me.

that Andy Halsall dropped onto the list at the start of this whole
thing. (the epc long thing that ian frreser said he would try and get
some answers to, but still hasnt) -ashley doesn't really seem to
understand very much about the issues laid out in this letter and has
really failed to adress any of the issues...
I'll try commenting on the blog, but i suspect you have more influence.

FTA:
"In fact, more than most: the vast majority. Something like just one
twentieth of one percent have accessed a BBC iPlayer programme via a
hack."

The whole point about the recent update is that the server really
can't tell if the client is an iPhone or not, so where does that stat
come from? I'd also like to see numbers regarding actual iPhone visits
Vs the number of people that actually own an iPhone. I would just love
for that ratio to be greater than 1.

Good post though. It really does see like the general consensus from
the Beeb is that they recognise this sort of inquisitive hackery isn't
malicious or harmful, which was always what I thought which just makes
the warning post I got last week from James Cridland seem really odd.

I don't understand why getting media in a loggable, traceable manner
over the internet is somehow more dangerous than getting it from a
nationwide broadcast (at a much higher quality). I probably wouldn't
be bothering with this at all if I could get a digital TV reception in
my house - I'd just be storing the shows to HDD on a PVR like everyone
else.

I look forward to the day when this will seem as ludicrous to BBC
management as it does to everyone else right now.

Cheers,
Iain

Perhaps they are tracking download speeds and guessing from that? Will
the mp4 be pulled at a much faster rate by curl/wget than it would
have been by an iphone that downloads it incrementally for realtime
viewing?

If I was trying to detect this stuff I'd be looking for people with abnormal 
behaviour such as clients that grab an html page and then the mp4 without 
grabbing any other collateral such as style sheets, images and so on.

Can't be hard to figure out given the logs.

Cheers,
Al.

May flag people using caching proxies.
Proxies may not cache the HTML as it changes more frequently and it's
highly unlikely they cache the MP4 stream. They would cache images and
style sheets though.

Way to confuse me! I had to check the To address to make sure this was
backstage and not Ubuntu-UK ;)

> Perhaps they are tracking download speeds and guessing from that?

Someone suggested speed limitng wget to make it look more iPhone-ish.
Most probably pull it full speed

Incidently I am trying to work out how to *stream* as I thought it
might be good to get something running on Android but it will take me
a long while (if ever, why is it no matter how much you know it is
never enough?).

This is true. I don't think you could reliably differentiate between
an iPhone and a script pretending to be an iPhone.

*maybe*, but considering the interface only lets you view video if
you're viewing from a wifi connection and not the phone's data
connection (just a javascript check) then the only difference is, as
suggested Quicktime limiting itself or pulling down a chunk of data at
a time which is entirely possible but doesn't seem very likely.

I don't really know much about Android. Does it have its own native
video player?

The download scripts let you download an entire iPlayer MP4 in a
matter of minutes or seconds. AFAIK, Quicktime on the iPhone streams
the programme gradually, with a read-ahead buffer of a few megabytes
(which is much kinder to the BBC's servers!)

Hence if a programme was downloaded in 5 minutes but the show lasts 30
minutes, it was probably leeched!
