Re : TVDownloader: télécharger les médias du net ! [2]

@ 11gjm

Je vais être franc, je me contente de faire un mediainfo sur les vidéos téléchargées, et je ne savais pas qu'il y avait plusieurs versions, VF, VOST...

Je vais regarder.

Re : TVDownloader: télécharger les médias du net ! [2]

Bonjour!

@11gjm: Merci pour tes conseils; je pensais modifier la boucle de téléchargement du script pour ne pas avoir à le relancer à la main, mais k3c nous fournit déjà une nouvelle version parfaitement fonctionnelle smile
Concernant les versions VOST/VF: je préfère les VO mais les VF sont disponibles (pour l'épisode 15: rtmpe://wske.wat.tv/ondemand/mp4:vod/H264-384x288/37/29/10433729.h264) mais juste en 384x288 apparemment...

@k3c: Merci pour cette nouvelle version avec le nouveau hash swf! je reste curieux de savoir comment tu l'obtiens (la redirection avec iptables et rtmpsrv ne m'a rien donné) big_smile

Re : TVDownloader: télécharger les médias du net ! [2]

@ k3c
à mon tour de te remercier pour la maj ! je me demandais si on ne pourrait pas intégrer le calcul des hash du lecteur flash dans le script pour éviter ces désagréments. Est-ce que tu les as calculés toi-même ou les as-tu récupérés d'un autre programme ?

@ 11gjm
les version françaises et originales sont des vidéos différentes : il ne s'agit pas d'une option comme c'est parfois le cas par exemple pour la qualités de la vidéo (qualité standard ou haute), il y a bein une adresse différente pour chacune d'elle. Exemple S02E18 VF et S02E18 VO.
Il suffit donc d'utiliser le bon lien comme argument du script. Comme signalé, la vo est en SQ et HQ tandis que la vf est uniquement en SQ.

--
		playerDataUncompress = self.decompressSWF( playerData )
		# Perform sha256 of uncompressed SWF player
		hashPlayer = hashlib.sha256( playerDataUncompress ).hexdigest()

Re : TVDownloader: télécharger les médias du net ! [2]

Bonjour,

Je vous propose ma petite contribution qui intègre:

  • une correction d'indentation qui empêchait le script de sortir à l'issue du téléchargement

  • une conversion ffmpeg pour corriger le conteneur de la vidéo téléchargée (qui rendait la lecture impossible sur notre téléviseur roll)

  • la suppression de quelques print

J'ai utilisé os.remove pour supprimer le fichier temporaire de façon à rester indépendant de l'OS, puisque je crois que ffmpeg/avconv existe aussi pour windows et macOS.

Par contre je n'ai pas encore réussi à recalculer le hash du swf: j'ai récupéré le player à l'url http://www.wat.tv/swfnt1/264128nIc0K1110456151 et utilisé le code de PluzzDL.py, mais la chaîne obtenue ne correspond pas... hmm
Ce n'est peut-être pas la bonne url, ou il faut lui passer des arguments?

Re : TVDownloader: télécharger les médias du net ! [2]

@ pacome

Ca fait plaisir de voir des personnes contribuer ! Surtout quand chaoswizard et vermouth semblent abandonner le projet.

Extrait de
http://stream-recorder.com/forum/rtmpdu … ight=flasm

SWF Verification
Download the swf player you want to use for SWFVerification, unzip it using
Code:
$ flasm -x file.swf
It will show the decompressed filesize, use it for --swfsize

Now generate the hash
Code:
$ openssl sha -sha256 -hmac "Genuine Adobe Flash Player 001" file.swf
and use the --swfhash "01234..." option to pass it. e.g.
Code:
$ ./rtmpdump --swfhash "123456..." --swfsize 987...

Et ça fait longtemps que je ne l'ai pas fait, en grand paresseux, je me contente de lancer un téléchargement par Captvty, puis je fais un

wmic process get commandline

Sinon, je vais proposer une modif mineure du script, le test pour savoir si on est sur TMC ou TF1 ... est mauvais.
/sujet à  problème. Il faudrait utiliser urlparse et tester juste la bonne partie de sys.argv[1], pas soup.

Re : TVDownloader: télécharger les médias du net ! [2]

Bonjour ,

@k3c : lors de la tentative , pour essayer la v0.9.3 , je n'ai pas pu tester .

J'ai un problème avec le fichier "urllib2.py" qui date du 10/04/2012 .
Au niveau des lignes : 126,378,400,418,1177,1207.

Est-ce que quelqu'un pourrait le copier et le coller ICI , entre code et /code ? MERCI .
Je n'ai pas envie d'effectuer l'install , vu que je suis sous Windows .

A+ .

Enjoy (en théorie 1463 lignes, je ne suis pas sûr que tout y soit)

"""An extensible library for opening URLs using a variety of protocols

The simplest way to use this module is to call the urlopen function,
which accepts a string containing a URL or a Request object (described
below).  It opens the URL and returns the results as file-like
object; the returned object has some extra methods described below.

The OpenerDirector manages a collection of Handler objects that do
all the actual work.  Each Handler implements a particular protocol or
option.  The OpenerDirector is a composite object that invokes the
Handlers needed to open the requested URL.  For example, the
HTTPHandler performs HTTP GET and POST requests and deals with
non-error returns.  The HTTPRedirectHandler automatically deals with
HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler
deals with digest authentication.

urlopen(url, data=None) -- Basic usage is the same as original
urllib.  pass the url and optionally data to post to an HTTP URL, and
get a file-like object back.  One difference is that you can also pass
a Request instance instead of URL.  Raises a URLError (subclass of
IOError); for HTTP errors, raises an HTTPError, which can also be
treated as a valid response.

build_opener -- Function that creates a new OpenerDirector instance.
Will install the default handlers.  Accepts one or more Handlers as
arguments, either instances or Handler classes that it will
instantiate.  If one of the argument is a subclass of the default
handler, the argument will be installed instead of the default.

install_opener -- Installs a new opener as the default opener.

objects of interest:

OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages
the Handler classes, while dealing with requests and responses.

Request -- An object that encapsulates the state of a request.  The
state can be as simple as the URL.  It can also include extra HTTP
headers, e.g. a User-Agent.

BaseHandler --

exceptions:
URLError -- A subclass of IOError, individual protocols have their own
specific subclass.

HTTPError -- Also a valid HTTP response, so you can treat an HTTP error
as an exceptional event or valid response.

internals:
BaseHandler and parent
_call_chain conventions

Example usage:

import urllib2

# set up authentication info
authinfo = urllib2.HTTPBasicAuthHandler()
authinfo.add_password(realm='PDQ Application',
                      uri='https://mahler:8092/site-updates.py',
                      user='klem',
                      passwd='geheim$parole')

proxy_support = urllib2.ProxyHandler({"http" : "http://ahad-haam:3128"})

# build a new opener that adds authentication and caching FTP handlers
opener = urllib2.build_opener(proxy_support, authinfo, urllib2.CacheFTPHandler)

# install it
urllib2.install_opener(opener)

f = urllib2.urlopen('http://www.python.org/')


"""

# XXX issues:
# If an authentication error handler that tries to perform
# authentication for some reason but fails, how should the error be
# signalled?  The client needs to know the HTTP error code.  But if
# the handler knows that the problem was, e.g., that it didn't know
# that hash algo that requested in the challenge, it would be good to
# pass that information along to the client, too.
# ftp errors aren't handled cleanly
# check digest against correct (i.e. non-apache) implementation

# Possible extensions:
# complex proxies  XXX not sure what exactly was meant by this
# abstract factory for opener

Re : TVDownloader: télécharger les médias du net ! [2]

Pour le fichier
saison-2-episode-18-le-passage-7927329-846-10434745.t.mp4
La commandertmpdump -e -r ...etc
est tout de suite suivie de

Erreur : le sous-process s'est terminé avec (le code d'erreur est 1)

qui se répète à l'envie.
Pour le fichier de tf1, j'ai la même erreur, que j'ai stoppée après la deuxième répétition du message et là j'obtiens une info supplémentaire :

^CTraceback (most recent call last):
  File "Bureau/fichiers_TVDownloader/tf1-tmc-v093.py", line 145, in <module>
    main()
  File "Bureau/fichiers_TVDownloader/tf1-tmc-v093.py", line 130, in main
    time.sleep(3) 

Pour hercule Poirot, même comportement que pour tf1

@k3c: La disponibilité de chacun est variable avec le temps et d'autres facteurs (famille, santé, boulot, projets, etc.), mais tant mieux si je peux contribuer à améliorer ces outils qui me rendent bien service wink

Ceci dit...

@11gjm: je crains que ce soient mes modifications, et plus précisément l'appel à ffmpeg, qui provoquent les erreurs que tu rencontres.
Je n'ai plus de windows depuis bien longtemps, je ne pourrais donc pas t'aider beaucoup de ce coté-là, mais as-tu installé ffmpeg (windows build) sur ton système? si oui il faudra modifier l'appel pour lui donner le chemin complet ou la casse (FFmpeg?); v0.9.3 ligne 133:

                    # conversion ffmpeg fName.t.mp4 → fName.mp4 (pour corriger le conteneur)
                    cmdFfmpeg='ffmpeg -i "%s.t.mp4" -acodec copy -vcodec copy "%s.mp4"' % (fName, fName)

Comme ffmpeg est utilisé dans PluzzDL.py je ne me suis pas posé la question, mais il faudra que je rajoute un test pour vérifier qu'il est là et un petit message explicite si ce n'est pas le cas...

J'ai bien l'intention de creuser cette histoire de hash swf aussi (merci pour le lien k3c) puisque je n'ai pas de windows tongue!

@thom83: Je viens de re-tester et je n'ai aucune erreur; essaye de copier-coller le script à nouveau pour être sur.

Bonjour ,

Nouvel essai après modifications :

_ encodé le fichier "TF1_TMC_NT1_HD1_v0.9.3.py" en utf-8
_ ajouté ffmpeg
_ ajouté rtmpdump (v2.5)

Résultat pour "fringe/saison-2-episode-18-le-passage-7927329-846.html" :
Aucune anomalie constatée .

Re : TVDownloader: télécharger les médias du net ! [2]

j'ai les mêmes erreurs que toi et je crois que cela vient de la version de rtmpdump
Avec Ubuntu 10.04 en version amd64, j'ai rtmpdump  2.4~20110711.gitc28f1bab-1 et n'en ai pas trouvé de plus récent.
J'ai refait l'essai avec le dernièr script qui porte le numéro 0.9.3 qui lance la commande

rtmpdump -e -r "rtmpe://wske.wat.tv/ondemand/mp4:vod/HD-1280x720/65/85/10456585.hd" -c 443 -m 10 -w 0818931e9bfa764b9c33e42de6d06f924ac7fc244d0d4941019b9cdfe8706705 -x 352043 -o "episode-13-saison-02-le-dernier-metro-7929103-10456585.t.mp4"

Comme indiqué précédemment, cela se termine par

Erreur : le sous-process s'est terminé avec (le code d'erreur est 1)
^CTraceback (most recent call last):
  File "fichiers_TVDownloader/tf1-tmc-v093.py", line 145, in <module>

  File "fichiers_TVDownloader/tf1-tmc-v093.py", line 130, in main
    time.sleep(3) 
KeyboardInterrupt

Par curiosité, j'ai utilisé, pour la même émission, le fichier touvé au # de ce fil. Il me donne la commande suivante

rtmpdump -e -r "rtmpe://wske.wat.tv/ondemand/mp4:vod/HD-1280x720/65/85/10456585.hd" -c 443 -m 10 -w b23434cbed89c9eaf520373c4c6f26e1f7326896dee4b1719e8d9acda0c19e99 -x 343427 -o "episode-13-saison-02-le-dernier-metro-7929103-10456585.mp4"

Quand je la lance, cela se termine par

Il est à noter que ce qui suit le -w n'est pas identique dans les deux commandes...

Re : TVDownloader: télécharger les médias du net ! [2]

@thom83
je pense que tu fais référence à la version que j'ai postée, donc au premier message de ce fil.
le script devrait être encore fonctionnel à condition de changer les hashs du lecteur flash donc les chaînes qui se trouvent après les options -w et -x de la commande rtmpdump. regarde dans la nouvelle version du programme et édite la version précédente en conséquence...
je n'ai pas testé la nouvelle version du programme mais d'après ce que j'ai lu, c'est un peu de cosmétique et rien de fondamental, non ?

Je viens de passer sous Ubuntu 12.04 avec aussi rtmpdump 2.4~20110711.gitc28f1bab-1.
Le dernier script de k3c charge l'émission de tf1 sans se plaindre. Le script du 20 mars n'est plus adapté en effet.

Re : TVDownloader: télécharger les médias du net ! [2]

Bonjour,

J'ai ré-essayé d'utiliser les fonctions de calculs du hash swf de PluzzDL.py dans le tmc_tf1.py, mais il doit y avoir un truc qui m'échappe parce que je ne récupère pas le hash qui fonctionne... et puis à force de l'avoir devant les yeux régulièrement j'ai fini par voir cette option de rtmpdump: --swfVfy|-W url   URL to player swf file, compute hash/size automatically roll

Je vous propose donc une nouvelle version qui intègre:

  • l'utilisation de l'option -W <URL Player swf> (j'ai trouvé sur www.wat.tv un autre player que celui proposé par JUL1EN094, mais je n'ai pas automatisé cette recherche)

  • la vérification de la présence des programmes externes requis (il faudra que je revois la vérification des versions)

  • et du coup l'utilisation optionnelle de ffmpeg (si il n'est pas installé c'est pas grave big_smile)

  • la déclaration de variables concernant ces points en début de code (c'est plus facile à modifier si nécessaire)

Re : TVDownloader: télécharger les médias du net ! [2]

Bonjour ,

@pacome : Merci pour ton travail .

J'avoue être un peu dépassé , par tes recherches .
Mes essais avec la V0.9.3 sont concluants .

Existe-t-il d'autres points qui nous empêchent d'obtenir les vidéos ?

Cordialement .
