So I have a Roku channel that is completely powered by Vimeo. However, the other day Vimeo changed around some of their links that are included in the API call. Now, all the links have an ampersand in the URL to the videos.
In the past when we had our own CDN I could create scripts and links at will to not include an ampersand. However, I am still using the simple video player example that came with the Roku SDK examples and for some reason video links with ampersands will not play.
Is there something in the Brightscript code that I need to change to play links with ampersands?
How can I change this channel around to work with video URLS that contain ampersands?
Hmmm, i cannot think of a reason why Roku won't load files with & in the URL.
But i have a suspicion the reason may be somewhere else: do you by any chance pass the content (list of videos etc) to the player as XML? You should make sure ampersands in text and attribute values for XML are escaped to & - otherwise roXmlElement.parse(xmlText) acts unreasonably. And by "unreasonably" i don't mean it loses the & or shows error, rather it silently drops whole elements or subtrees.
Pro tip: if parsing XML on Roku and suspecting something might have got lost in parsing, use myXmlElem.genXML() to dump it back to console.

I am developing a web application, where a mp3 player is present and user can play the music. Issue that i am facing is how to keep the music playing (and the player untouched) even when I change the URL - go to a different page? The same thing as Deezer or SoundCloud do. You can browse the web and listen to the music meanwhile. Please point me a direction how to implement it. Thank you all!
On soundcloud they don't actually change the page they just change some of the body content with javascript. You can simply do the same, by adding a hidden div for the music, and a div for the content, which calls an api (recommend jquery.ajax) to fetch the content relative to the url in the address bar.
With rewriterules inside the .htaccess file, you can make it so it ignores all query strings etc. So it will always load the index.php file.
In short, this is no rocket science, has nothing to do with html5 nor soundmanager2. For more info you should use the .htaccess and jquery tag.
Is it possible to get the download URL of currently playing video from source of YouTube webpage?Thanks in advance.Please help me.
Actually I have a downloader but it is not working now.When I have tried with the URL provided by the downloader in browser it returns an error page says "Access to the webpage was denied".The Url that I got for a video is as
" http://r14---sn-h557snel.c.youtube.com/videoplayback?gcr=in&ip=121.241.181.70&upn=OOcjKEO_S6I&cp=U0hUTFZQT19KU0NONF9OSlNGOmFRT2JSUUs2bDVi&ipbits=8&fexp=900148,920704,912806,928001,922403,922405,929901,913605,929104,913546,913556,908496,920201,913302,919009,911116,901451,902556&ms=au&mt=1357625350&mv=m&id=31a79fcdbfc6c2f6&sparams=cp,gcr,id,ip,ipbits,itag,ratebypass,source,upn,expire&expire=1357651559&itag=18&key=yt1&newshard=yes&source=youtube&ratebypass=yes&sver=3"
Few months before the format of URL was

So I don't know whether the downloader gives the correct URL. Please help me
Sorry I looked around and I couldn't find a way to directly download the source file from the youtube link. There are some guides out there but they all are around 2009; and since youtube changes their code a lot currently none of them work.
Although there are many websites, addons, apps that allow you to download videos; but I do not think they work from a code from the link. Since to watch a video you have to temporarily download it I think they all use a method of opening the page, playing(downloading) the video and actually saving it. I would list those websites and addons but since those sources are not that hard to find; I assume you are trying to build your own downloader and not use one that is already out there.
Also on another note if you could somehow get a link to a videos source file. I am sure youtube has permissions blocked access on all folders and files on their backend for security measures; only allowing those files to be forwarded and displayed on the actual player page. And if you think embedded videos would somehow work they still just make a request to youtube which youtube then gives back video-feed-data so there still is no direct connection to the file.
You should use the player API https://developers.google.com/youtube/js_api_reference#Retrieving_video_information
player.getVideoUrl():String
Returns the YouTube.com URL for the currently loaded/playing video.
I have written a simple python code that can fetch youtube href from html code.
hope it can help you:
#!/usr/bin/env python
import re
pattern = '.*<(iframe|param).*(src|value)="(?P<link>http://www.youtube.com/(embed|v)/[a-zA-Z0-9/\.\?&;=\+_-]+);?.*".*>.*</(iframe|param)>.*'
action = re.compile(pattern)
result = action.findall('<div><iframe.....></iframe><param......></param></div>')
print result

I have a webpage that offers dynamic downloading of mp3 files through mobile phones. I would like to add a feature where someone can listen to the song through their desktops before downloading the file.
The challenge is, I don't want the mp3 file link to be displayed in the page code, I would prefer a different url e.g
<a href='http://mysvr.com/getfile/121233444/'>Preview song</a>
which is passed on to a player that expects an mp3 file source and get it to play the file.
I don't want the person previewing the file not know the real url of the file that is playing to prevent unauthorised downloads.
What do I need to do?
First deny all the access to the directory which has mp3 files through the internet. Then write a handler file to play the mp3's. The handler file will get the name of the mp3 from query string and play the file on player. Taking the url , parsing and playing will be done in codebehind so users wont be able to see the url of the mp3
hope it helps.
This would depend on your setup. The only real way to not make it visible would be to use server side code (php, asp etc). Any client side code is by definition visible to the end user. You could try to obfuscate the link e.g. using some minimized JavaScript hidden away somewhere, but it will always be visible to anyone who searches hard enough.
I've been able to play media with a html5 audio element but the duration of the song never displays correctly, and when it plays the progress bar just fills up, although it does play fine. This is what I've been doing. I'm using ogg vorbis files.
Started with jPlayer, had this problem.
Heard the problem might be related to my Jetty server so I switched to Tomcat, but I still had this problem.
Tried using the plain html5 audio element and the problem persisted.
Put a video in my page with an html5 element, and that had the correct duration.
I imported all my audio from CDs using the same program, so although I can see the duration any number of other ways I thought I might try files from some place else. So far every file I try has the problem.
I've been hearing about an Accept-Ranges header but I don't know how to see if I'm using that header, how I would make sure to use the header, or when I would use the header(do I send it with the html page, do I send with with the audio itself? Can I add a header to a file?)
I'm very new to web programming and figuring out the ropes have been tough. In the end I just added the "Accept-Ranges" : "bytes" to every response my server returned. I thought I would have to be careful what responses I added headers to but this is working out. In clojure with compojure which is the language and framework I'm working in I just use a middleware that adds "Accept-Ranges" : "bytes" to the response map under :headers and it looks like there is a setHeaders function in the response object in Java.
I would like to know whether it a possible to detect whether a HTML page contains a video.
I know that one possible way is to look for ".swf" in the HTML source code. But most of the pages do not contain the file name.
For example, given following URL and possibly its source code, is it possible to find out whether it contains a video:
http://www.cnn.com/video/
There are many ways to embed Video into a HTML page - as Flash Video or instances of Platform-Specific players through <object> and <embed> tags (but not every one of those tags is a video! The same holds true for .swf - it's just the file extension of Flash files, Video or not), the new HTML 5 <video> tag... They are not impossible to find out but it's a lot of work to catch all possible player types, formats and embed codes, and will result in a lot of false positives / negatives.
Then, there are JavaScript libraries that initialize players after the containing page has loaded - those are almost impossible to detect.
It's still a very complex issue to get video into a web page reliably, and subsequently, it's even more complex to find it out. Depending on what you are trying to achieve, I would consider dropping it.
For your case (CNN site) you can parse Open Graph micro-markup for a video information.
Meta tags such as og:video:type, og:image will help you.
Video hosting services usually support micro-markup, e.g. open graph or scheme.org.
So you can parse these markups.
Check if an <object> tag exists in the DOM and check its content type and parameters. You will find the pattern by yourself.
You can also search for .flv, or .mp4 in the source code.
