Record Pluzz.fr from linux

bibichouchou · #1 04-15-2012, 11:36 AM

Hello,

I would like to write a small program (bash, python, anything

) in order to download videos from www.pluzz.fr, a French catch-up website.
I wrote one that used to work but they changed their authentication system in february/march and since then, i have been stucked.

here is a video that may work abroad:
http://www.pluzz.fr/jt-13h.html

They used adaptive streaming from Adobe. The problemn I encounter is the getting of the authentication token, mandatory to download video segments. As far I know, no solution exists for linux.

Any help is welcomed.

PS: i posted also in the French section.

how do you suppose to play or join those segments? do you know about any player or decoder which can do it. AFAIK there isn't any player or decoder available except Flash Player / Strobe Player. until you can find a solution to play or decode them there is no point trying to download them.

Hello KSV,

First, thanks a lot for your PHP script for playtv.fr. It is great !
Yes I can join the segments and reconstruct the video (and play it with vlc or mplayer). I used to do it until end of February when they changed their protocol. The only thing preventing me to get the video is a token. I don't know how it is generated or how i can retrieve it. I can see it when I use a Firefox add-on.

cheers

@chap

ok thanks. I gave a wrong example because for this specific video 2 means are used to broadcast it: a "classic" mms video and an hds (http dynamic streaming) video.

if one goes to this page:

http://www.pluzz.fr/appftv/webservic...usion=62158552

one can see the two links leading to the video: the mms link you gave and the http link pointing to a file called manifest.f4m
The content of this file describes the video (different qualities available...) and looks like:

Code:

as they use geolocalization, maybe only the mms link is available abroad.
of course, most of the video use the hds method

KSV · #6 04-15-2012, 01:55 PM

i haven't checked the site yet but value of pv-2.0 in your manifest file looks like authentication token. if possible can you share your method of joining HDS fragments.

bibichouchou · #7 04-15-2012, 02:27 PM

@KSV

no the value of pv-2.0 does not work. I tried to use it but never could download any fragments with it.
of course, i can share the joining method. to be honest, i have to precise that i am not the original author

KSV · #8 04-15-2012, 02:55 PM

i will take a look at site tomorrow. it shouldn't be too hard.

KSV · #9 04-19-2012, 03:35 PM

i have finally solved the mystery of token generation. analyzing a VM (Adobe Alchemy) within another AVM (ActionScript Virtual Machine) isn't an easy thing to do. PVToken (Player Verification Token) generation was easy stuff but the hardest part was to generate the hmac value to sign the player verification response.

i can share my method with you if you can share the method of joining HDS fragments. i am asking this because i have literally spent hours on this and i don't wanna help someone who is just gonna use my method to rip and embed those streams into his own site.

saadeva · #10 04-19-2012, 04:08 PM

Hi there.
What you're saying is just wonderful. I reaaaallly hope this chap will share his method because I think you're awesome news

Those "pluzz" people, they've been changing the protocol and access and all a lot lately and people who were doing the software to get the videos, they got pissed off and so the existing software development is kinda stalled.

I myself don't understand everything, but I'll give you some link, hopefully it helps, even if I think that would be more than welcome if the original poster of this thread would share technical details with you directly.

http://code.google.com/p/tvdownloader/downloads/list
the software is called pluzzdl and its able to get the fragments and put em back altogether. It's opensource python, maybe you can have a look at it later, if you don't get your answer here, so maybe, if that was okay with you, you could share with pluzzdl team...

Sorry to be bothering, I'm just an end user who'd really like this (free as in freedom and people working together, giving credit and all) software to work once again
