Problème lecture video flashplayer

Bonjour,
j'ai un problème de lecture des vidéos sur internet avec flashplayer sous firefox.
En gros voilà ce qu'il se passe :
     - lancement de la lecture
     - début de lecture (son + video)
     - le son se coupe après 3-4 secondes
     - l'image se fixe 3-4 secondes plus tard
     - la video ne reprend pas
     - la video continue à charger
     - si je clic pour aller plus loin dans la video sur la barre de lecture, la video reprend mais reblocage comme précédemment
j'ai essayé toute les instructions de la page
      http://helpx.adobe.com/fr/flash-player/kb/flash-player-games-video-or.html
j'ai relancé firefox et redémarré mon ordi.
je n'ai pas le problème sur internet explorer (mais préfère utiliser firefox).
une solution ??
merci

Cannot sync iTunes U lecture videos to iPad Air

iTunes U lecture video link
https://itunes.apple.com/us/itunes-u/image-processing-reconstruction/id547294162 ?mt=10
I have this problem that cannot be fixed, no matter what I tried.
For most of the videos downloaded from iTunes U, I can sync from iTunes in Windows 7 to iPad Air fine. However, the videos from the link above can only be synced for the 2nd lecture while the rest have the error "were not copied to the iPad ... because they cannot be played on this iPad".
So, I tried to convert first using iTunes, make iPad version. That didn't work.
I downloaded Handbrake and used the preset "iPad" and "Universal", and that also didn't work. (at this point, I tried to encode using Handbrake with different presets for at least 4 hours).
It keeps saying "... because they cannot be played on this iPad".
So I tried to do the last thing on my mind, download the video lectures directly through my iPad. It worked, it kept the all the files (except the 2nd lecture which is "Processing" indefinitely, ironically).
However, the next time I synced it with iTunes to transfer more files (PDFs), the video lectures downloaded directly were wiped since it didn't download it through iTunes (the first time it copied the files from iPad to iTunes while the second time it wiped the video lectures from my iPad, except for the 2nd lecture that can be transferred).
My problem is... how is it possible that iPad can play the file yet iTunes still report an error that it cannot be played? Please keep in mind I tried re-encoding it numerous time already.
How can I keep the video lectures file on my iPad without downloading it through my iPad everytime I want to watch it after I sync my iPad with iTunes?

Stumbled onto information from another forum. MAYBE this is the problem, but what are solution options? What I did confirm is that ALL of the podcasts and iUniversity files that will not sync are MPEG 4 files. Let me know your thoughts.
Taken from another conversation to someone having a similar issue:
I just downloaded a full HD podcast video from iTunes to my iPad and desktop computer. Both of these videos play just fine. When I synced the iPad to my desktop computer iTunes would not transfer the video to the iPad. The video is 1920x1080, this outside the guideline for iTunes to transfer the video to the iPad.
The iPad is capable of playing a 1080p videos. When i need to send a 1080p to my ipad I use the GoodReader app to do so. It is iTunes (on the desktop) that is placing these restrictions on the videos that can be transfer to the iPad.
If you want to you can voice your opinion to Apple:
http://www.apple.com/feedback/ipad.html
*H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

College lecture video (H.264 M4V) says not compatible

I have a lecture video from blue review that is H.264 M4V, which should be compatible and has played on my mac before, however now it is saying it won't play. All of my software and itunes are up to date. What should I do?

Hi cdonley21,
What's the exact error displayed when you try to play the file in QT? Did you test it in VLC player?
Maybe your clip has got corrupted somehow. Check whether any other copy of the file is able to play.
If no other copy is available then you could check whether the file can be repaired using Treasured. Best of luck!

Split 3 hour lecture video into a 3 part series...

Trying to figure out how can I maintain quality and send it to youtube? Would you split the video up more into maybe 6 parts? I dont wont to loose any quality and I need the full 3 hours of video because its lecture. I want to put it on youtube. What is the maximum size that i can upload to youtube? I have uploaded over a gig at one point. I recorded my video at 60i in MXP mode with my canon xa10.

AFAIK, you could load the full lecture. Check to ensure that your account permits videos longer than 15 minutes and upgrade if it doesn't. A three hour video file at FCP's default YT setting should weigh in at about 12 GB. Huge to be sure, but in theory it should still be OK. I would export from FCP and then use their uploader; definitely would not try to upload it through FCP.
As a practical matter, however, you might want to break it into parts – just to guard against the possibility that a connection glitch might occur after hours of uploading. That would be frustrating, so why tempt fate?

Problème lecture visa RS 232

Bonjour,
Dans le cadre d'un projet, je dois récupérer diverses mesures de pression, débit ou températures. Pour la mesure de pression, j'utilise une connexion série via un RS 232.
Après avoir configuré le port série (Baud, nombre de bits...) j'ai effectué une lecture sans problème. Sauf que je ne récupére pas les mesures de la bonne voie. Pour ceci, j'essaye d'écrire la commande avec l'aide de la documentation du capteur. Je n'obtiens d'ailleurs pas d'erreurs dans l'écriture, ni en lecture seulement un warning 1073676294 et surtout je n'arrive plus à obtenir la moindre mesure.
D'avance merci

Problème Lecture/Ecriture fichier binaire

Bonjour,
Mon objectif est de créer un programme qui permet de lire un certain nombre d'octets dans une trame qui se répète plusieurs fois dans un fichier A . Il faudrait que je puisse enregistrer ses données dans un autre fichier binaire B.
J'ai réalisé deux VI, un permettant la lecture et le filtrage des données, un autre permettant l'écriture des données dans un fichier à part.
Celà fonctionne presque... En fait lors de l'écriture des données dans le nouveau fichier B , 4 nouveaux octets apparaissent sans qu'ils ne soient présent dans les données que j'envoie à la fonction "Ecrire dans un fichier binaire". Après quelques tests, je me suis aperçu que ces 4 octets représente le nombre d'éléments que je récupère à la lecture du premier fichier A..
Par exemple, si je décide de lire 4 octets par trame dans le fichier A, le traitement se passe correctement; et j'enregistre ces données dans un tableau.
Ensuite lorsque je transfert les données de ce tableau dans le fichier B, devant chaque élément je trouve 00 00 00 04. J'ai aussi remarqué que ces octets sont au format Big-Endian alors que je travaille au format Little-Endian.
Exemple en images :
Le fichier départ est octets_départ.jpg << En rouge les 4 octets que je sélectionne.
Le fichier final est octets_final.jpg << En rouge les 4 octets sélectionnés précedemment, en vert les 4 octets non demandés !
Je peux fournir les fichiers VI si besoin.
Merci d'avance à ceux qui prendront la peine de me lire,
Cordialement,
English :
I want to realize a program who read binary file and keep only words I want. So I wrote two VI for this. One who read the first binary file A, and one who write these data in a binary file B.
My problem is when I write the data from the file A, I write 2 words I don't want to write too. Apparently, these words represent the number of words I select in the first binary file A.
These images show that.
The first picture : octets_départ.jpg << In red the words I want to keep.
The second picture : octets_final.jpg << In red the words I keep from the file A, in green the words I don't want and I don't know.
I can send the VIs if it's necessary..
Best regards,
Thanks for your attention.

J'ai trouvé la solution.
La fonction "Ecrire dans un fichier binaire" intègre une entrée permettant de choisir si l'on veut ajotuer la taille ou nom de ce que l'on écrit. Je n'avais pas câblé cette entrée, et donc par défaut, il m'ajoutait la taille.
Il faut rajouter une commande ou une constante booléenne de valeur "FALSE" pour éviter le problème que j'ai décrit plus haut.
Merci quand même.
Cordialement;

I have found ! The function "Write to binary file" include an entrance to specify if you want to add the Size of the data you write. I had put nothing on this entrance, so the default value was to add the size.
I add a constant value to FALSE in this entrance and I didn't have the problem
Thanks for your help.

No sound for Faraday Institute Lecture Videos

I've recently begun to explore the lectures by the Faraday Institue and I've come across a problem.
I can access and listen to all the lectures which come with a video but there are some lectures which do not come with a video (so it seems for me anyway). All other iTunesU files work fine except those lectures.
Thanks for any help!

is the switch on the side of the phone set to silent? did u try the vol+ in the app itself?

Problème lecture vidéos Flash

Bonjour
J'ai un petit problème pour lire certaines vidéos Flash sur un site.
Je tiens d'abord à préciser que sur le site d'adobe il est bien indiqué que je possède la derniere version de Flash Player, et tout marche parfaitement sur Youtube and co.
Donc au lieu d'avoir la dite vidéo, je n'ai qu'un fond blanc, pas de barre de lecture ou autre, non, juste un fond blanc...
Quand je fais un clic droit dessus, j'ai 2 choix:
- Animation non chargée (Grisé, impossible de cliquer dessus)
- A propos d'Adobe Flash Player 10...
Est ce que quelqu'un saurait comment je peux faire pour lire ces vidéos?
OS: Windows 7 Pro 64
Navigateur: Chrome ou IE8 (même problème)
Merci

ITunes U video content shows in Movies app

Hi,
The iPod touch doesn't seem to properly handle iTunes U content. The most notable and annoying aspect of this is the iTunes U videos which are on my iPod. They show up in the "Movies" app alongside my actual (theatrical or self-produced) movie files, and apparently in alphabetical order - so my movies appear in the middle of a series of lecture videos.
I have probably 50 iTunes U videos and 15 or so normal videos. The iTunes U videos drown out the normal ones when browsing the iPod!
The iTunes U files do show up correctly in the iTunes U section of the Music app. But I don't want them to appear anywhere outside of the iTunes U section. Can I do this?
Firmware 3.1.3, iPod touch 32GB 3rd gen

I had already tried that. iTunes says that it cannot convert the specified file because it is already in the necessary format... or some such thing!
FWIW: I can share my library and watch the "U" videos on other Macs just fine.
Thanks for suggestions.

Safari 6 lost audio in HTML5 videos

I used to be able to play HTML5 videos in Safari without a problem--but as of the past week or so, I get no audio. I did a couple of courses through Coursera this summer and the HTML5 videos worked fine. But now that I've started new courses, I have to use Chrome (which I don't like) or use the Flash versions of the video which are not as good. Anyone else encountering problems with HTML5 videos audio?
I've seen older posts about Safari not playing nice with Youtube HTML5s; but that's a long time ago and my Safari was working fine with HTML5 until the last week or so.
My MacBook Pro is mid-2012 and running : OS X 10.8.4 (12E55)

I was just searching for a solution to this exact problem before posting it here myself.
I am also a regulat Coursera student and had managed to watch and hear the HTML5 option videos without problem.
It must be difficult to visualise for people who aren't signed up to Coursera but not unlike YouTube, there are both Flash and HTML5 versions of lecture videos with inline content often in the form of quizzes (or tests, as we call them in the UK!). However, unlike YouTube, it is possible to change settings on the video page.
Just recently (probably aroung the same time Dominique noticed problems) the audio ceased functioning using the HTML option and the in video content and quizzes stopped using the Flash option.
I reported the problem to Coursera but got a pretty unhelpful response.
From Coursera:
Sorry to hear about this, and thank you for letting us know.
We have not had an unusual amount of students reporting issues with the video playback. If its a specific Video, please let us know which one so we can check it. If its the same for all videos on this site, and the problem is slowly getting worse, it sounds like an issue with your browser or cookies and cache.
First, could you please try clearing your browser’s cookies and cache and then let me know if the problem persists? You can find instructions on how to clear various browsers here.
(Link to page which lists the following)
Google Chrome (newest)
Note: Ubuntu users may have to install the chromium-codecs-ffmpeg-extra package to make the videos work in Chromium.
Firefox (23)
Note: The video speed change feature for lecture watching is not yet supported in Firefox.
Safari (newest)
Internet Explorer (9 or newer)
Also, could you kindly tell me what happens if you try this in another browser? You can find a list of Coursera’s supported browsers here.
If those suggestions don’t work, would you mind sending me a screenshot of the problem that you encountered? This will help us better diagnose the issue.
I got the feeling from the response that they hadn't read my message properly as it is not really possible to send a screenshot of either missing quiz or audio.
Anyway, for the record, I had already tried disabling extensions etc. and have cleared cookies and cache as Coursera suggested which has not brought the HTML5 audio back.
Every now and then, I do get an in video quiz using Flash but it's only about one in ten lectures. But the problem is extremely fustrating because it means that I have to load the video lectures multiple times (depending on how many quizzes etc. there are to watch the video in Flash until it reaches a quiz then reload it in HTML5 then reload it in Flash until the next quiz etc. etc.
