I'm working on a project where I need to batch convert files to multiple media formats, some of which will be streamed to iPhone. I'm using ffmpeg on a CentOS server, and have been using mediafilesegmenter locally to create m3u8 playlists, and it's gone swimmingly, but, in trying to get the process going on the unix server, I can't seem to find a ported/alternative version of mediafilesegmenter to use on a centOS server.
So, here's the question:
Where can I find a ported or open source version of mediafilesegmenter?
in addition, I'll need the same solution for variantplaylistcreator, although if absolutely necessary I imagine I could create a script to generate these.
Any ideas? I believe there is a tool called "segmenter" out there, but it's not in any of my repos, and I can't seem to track down a repo that has it.
You can now segment from ffmpeg directly. see https://ffmpeg.org/ffmpeg-formats.html#segment_002c-stream_005fsegment_002c-ssegment
I'm working at a company with some thousands of (payment) videos.
We are using (for more than 2 years) a segmenter based on Jesse's and works great get it here
PD: Older versions of ffmpeg have relevant bugs
Found this source : http://svn.assembla.com/svn/legend/segmenter/, which is an open source segmenter, on this article: http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/, which has some good info about streaming.
Just in case anyone else has this issue.
Also for anyone in future - have tried both this and another OSS segmenter - and they were causing some artifacts in playback in JWPlayer flash (but not in native iDevices).
Also, according to this Zencoder post - apple segmenter is more efficient with the streams it produces: http://blog.zencoder.com/2011/12/08/announcing-the-clouds-most-efficient-http-live-streaming/
I used Bento4 mp42hls tool to encrypt a media with the FairPlay on Linux.

Greetings & Salutations one and all
I'm new to mixxx been using it for about 4hrs and its a brilliant piece of software so thanks once again for this amazing program. The issues i'm having is that it creates and double m3u.m3u. extension when I'm live broadcasting. I had issues with getting this to work but figured it out with lame.dll which I didn't have to rename as this solution is for version 1 and below.
It works now after putting the lame encoder.dll file into the mixxx folder, which I think might be the issue i'm not sure. the live broadcasting connects successfully and it connects to my icecast server without issue, however when I click on m3u on icecast admin page or connect directly to it the web e.g. http://externalIP:8000/stream it show me the m3u.m3u error, which is causing the streaming error as its creating a double m3u file and as we know only .m3u works not m3u.m3u. so I think its the encoding creating this double extension but I'm not sure hence the post. any ideas??
mixxx m3u.m3u error
Make sure you configure a mount point in Mixxx.
Like /stream.ogg or /radio.opus, depending on the format/codec.
Also make sure that it does NOT end in m3u! The mountpoint is a virtual media file, not a playlist. The server will automatically generate another virtual file, a m3u playlist for it.
I have recently started working with a fresh install of FMS 4.5.0 and am having some issues getting my media to load with the VOD application.
After uploading some of my own FLV/F4V content to "/webroot/vod/", I am currently only able to load the samples from the installation.
Is there some sort of configuration that needs to be made to access my media?
Do I need to create a manifest for each video?
I have been running tests through:
http://www.osmf.org/configurator/fmp/
And have had luck accessing the videos that came with the install by using the following:
Video Source (URL): http://[my host]/vod/sample1_1000kbps.f4v
But when I change this to point to one of my recently uploaded videos it fails everytime.
Another strange note, I was able to play one of the samples but then I changed its name and it was still able to load that one specific video using the same filename when the file's name had changed. This leads me to believe that it isn't really loading the right files or perhaps I am uploading to the wrong directory. But I can't find any other directories that have video in them.
Please let me know if there is any more info you need to help me. I'm fairly new to this and am not sure what to include.
Thanks in advance for any help!
EDIT: This was a pathing issue.
This has been resolved.
Apparently my webroot directory for the server was not set up correctly and after it was pointing to the right directory it was fixed.
I suppose office files(prior MS office 2007) cannot be accessed using open xml sdk2.0 or if they cannot be programmatically accessed using the open xml format.
so is there any way to work or these older version files or can i view the xml content of these files.
or is it that open xml sdk isnt designed for that purpose
See the answer to a similar question I asked when I just started learning this SDK.
No but the open source project POI provides an API to most of the old formats. Warning POI is a bit (not a lot) buggy, does not fully implement the specs, and support is catch as catch can (ie it's open source).
You can use Office File converters to convert to open xml formats and start processing it.

I'm using this for my application. This works for me.
Hope this helps.
I'm writing an iPhone app which downloads a tar-gzipped file from a Webserver, then needs to unarchive this file so that it can be copied into the app's Documents folder.
I'm using tar/gzip because I want to download a whole bunch of small files in one HTTP request, to make everything nice and fast.
I've investigated solutions like http://www.feep.net/libtar/, but as a C/Objective-C newb, I can't get any of them to compile for the iPhone platform.
(I felt like I should just be able to do a system call to "tar -zxvf myfile.tar.gz", but it would appear it's not that easy!)
So is there a simple way to just un-tar a file on the iPhone? Or am I going about this all wrong, and is there a better way to do this?
Thanks in advance!
Nik
This blog post should help you:
http://blog.hawkey.org/?p=332
EDIT: Google cache version of the same page which actually links to a forum post here which links to a Google Code project here, containing some code which implements unzipping on iOS.
Here is a light untar library for iOS : https://github.com/mhausherr/Light-Untar-for-iOS

I took a different approach by building libarchive and bz2lib as a static library for iOS. You can find it here:

Could anybody explain to me the process of uploading to and downloading form and ftp server with the iPhone SDK. If you could just point me in the right direction (e.g. documentation etc.). How difficult is a task like this?
Thanks in advance.
You can use this. It support all the basic ftp operations:
Download file
Upload file
Delete file
Delete directory
Create directory
List directory contents
[DISCLAIMER] I am the developer of the library, I needed a ftp library too in the past and came over this answer. However, I decided to write one myself because s7ftprequest didn't support at that point several operations that I needed.(like download or list directory)
Try this Simple FTP Download
The Apple documentation will provide far more info in general than I could. Have a look at:
http://developer.apple.com/iphone/library/documentation/Networking/Conceptual/CFNetwork/CFFTPTasks/CFFTPTasks.html#//apple_ref/doc/uid/TP30001132-CH9-SW1
which details the FTP information you need. If you prefer a PDF with all the networking info in it, have a look at:
http://developer.apple.com/iphone/library/documentation/Networking/Conceptual/CFNetwork/CFNetwork.pdf
In this, you'll be particularly interested in Chapter 5. Both detail working with FTP sites, including uploading, downloading, retrieving directory listings, etc.
s7ftprequest only for uploading files to FTP.
The below is sample code from apple
http://developer.apple.com/library/ios/#samplecode/SimpleFTPSample/Introduction/Intro.html
Limitations:
FTPS (that is, FTP over TLS)
deleting items
renaming items
other less common FTP commands
custom FTP commands
I ended up using GoldRacoon. It turns out that in iOS/objc land, there's BlackRaccoon as the original FTP client lib, then WhiteRaccoon was forked from that, and then GoldRacoon was forked from WhiteRaccoon (I think)
pod search GoldRaccoon
... will show you.
I ended up making a few changes (in my own fork) so that you can pass in a successBlock & failBlock into any request, so that block-y callers (like my classes) don't have extra work to manage the delegate callbacks. Github link (my fork): https://github.com/xaphod/GoldRaccoon
