I know this is not programming related, but I have a scenario.
Each video streaming site has a flash video plugin and upon viewing the source I can find the link of the flv file it is streaming. Now I wanted to make an application or work on an existing one, where I can copy and paste the url of the flv file and it streams it for me. Something like an application which can stream flash videos for me.
Take an opensource flv player and plug it into your website and put the url of the flv files you want to stream.
Should work in most cases, in cases it won't work, you have the source code, so change it to overcome any issues :).
On the client side you can use this flash application to render the flv (works on any flv file) http://www.longtailvideo.com/players/jw-flv-player/ . Needs a license for commercial use (quite cheap).
On the server side you have to build an application which will stream flv files - but i guess that, if you want to use existing online flv files, you don't need this part.
Use Adobe Flash or the Flex SDK.

How do I download an m3u8 file from live streaming source on a mac. I do not want to lose any frame or bitrate or compromise on quality at all. I want audio and video to be in perfect sync like they are on the browser and want to save file as mkv or mpv extension. I browsed the internet and found out about ffmpeg but I do not know the exact way to do that without compromising on quality
Would really love any help here
I am trying to convert from wmv to mp4.
First of do I need to implement my IMFTransform to do this ?
Do i need to convert the video to MFVideoFormat_I420 ?
As far as I know if you create the topology correctly this should be handled automatically.
So I created my profile showed in the
http://msdn.microsoft.com/en-us/library/windows/desktop/ff819476%28v=vs.85%29.aspx
but i get a MF_E_TRANSCODE_NO_MATCHING_ENCODER.
I have windows 7 so, i should have the encoder.
Also Does anyone know where the source code for that tutorial is. It is not under SDK samples.
Thanks.
You don't show code - noone knows what is wrong.
Take a look at this transcoding sample, which comes with source code and does exactly what you are trying to do: transcoding from ASF into MP4.
http://blogs.msdn.com/b/mf/archive/2009/12/02/mfsimpleencode.aspx
MFSimpleEncode.exe - This is a command line tool that transcodes files
from one media format to another. The source code is provided to use
as a reference if you write your own transcode application. This tool
uses the Media Foundation transcode API, which was introduced in
Windows 7.
Examples:
Transcode ASF to MPEG-4:
MFSimpleencode.exe –i Input.wmv –o output.mp4 –p TranscodeProfileMPEG4.xml
Can anyone suggest me webplayer which can play MP3 files in Firefox browser?
I tried jPlayer, however it needs ogg files. I tried converting MP3 to OGA using FFMPEG, however, even the generated file is not being played in JPlayer.
Is there any alternate player which can play MP3 files in Firefox.
I don't want to use Flash.
..alternate player which can play MP3 files in Firefox.
Combine these 3 for an answer.
Java Sound for the ability to play audio.
The MP3 plug-in SPI of JMF, to supply support for MP3, which Java Sound does not support by default.
Applet - to embed that ability in a web page.
Note
I am pretty sure there are easy ways to embed sound in web pages that does not require Java, or requires plug-ins that have higher usage (like Flash). If there is not something custom you wish to do, I recommend investigating alternatives.
How can I playback an audio stream from a Icecast on WP7
I have tried SMF, SmoothStreaming Client and the MediaElement.
None of these have worked. The formats are either asx or and wma.
Edit:
Recently I found a new stream. this stream works when I'm in the designer. But it does not work on the device. On the device the stream is opened and closed immediately.
this stream is from an IceCast server in MP3 format. with a ?.mp3 extention. or without.
When you are streaming live radio, the stream may be encoded by an IceCast server or ShoutCast server. To read these streams, you will need to decode the stream in memomry and pass it to the MediaElement once it has been decoded.
have a look at Mp3MediaStreamSource
and Audio output from Silverlight
I lost tons of time on this, and this is the best solution I found so far.
Having had a quick look at the Icecast web site (I'm not familiar with their service) it seems that most of what they offer for streamed audio is offered in MP3 format, but that they provide this as playlists in either M3U or XSPF format. You can't provide this to any of the built-in controls or classes in the WP7 framework, but you can parse the contents of the file and pass that to a MediaElement to play individual files.
The M3U file is a simple list of the consituent URLs, so is the simplest to deal with, but the XSPF format (which is an XML format) provides more information, such as the title. You can easily use the XDocument class to parse the XSPF file and then use LINQ to query the contents.
You're not adding the ?.mp3 to the pls file right, to the embedded URL? IF you are using the URL you get from the PLS/M3U file, you might need to append a file extension to it. You can often do this by adding ?ext=.mp3 or ?file.mp3 to the URL and it should play with MediaElement, as I read on the MS dev boards that people had been getting that to work with Shoutcast streams.
Does your stream work on the device when you unplug it from the computer? Media playing doesn't work while you're plugged into the Zune sync center.

I have a mp4 file which is to be used in an application. Currently i am in the stage of figuring out the technology to be used for this job. I am familiar with flex and am hoping that i be able to use it for the application. But i can not figure out a way to play the file in flex. I have been able to play the file only in windows media player and that required the installation of three codecs : Mp4Audio.ax, Mp4Video.ax, Mp4Src.ax.
As i see it, it will be very convenient if i could embed a windows media player plugin in flex or i could specify the audio and video codecs in the flash player.
Else i will have to learn .Net, i guess.
Kindly help me out. Thanks in advance.
If you are creating an air app then you are able to start the windows-media-player using the NativeProcess. Anyway if you have a flex web app then you do not have any options on this. :(
My recommendation: Convert the video file to a valid mp4 file that can be played by flex. I suggest you to check ffmpeg library (and you could use it to convert the file to H264 format)
