I have received QTVR files (Panorama files) from my client and I was supposed to convert it to mov, and later convert it to mp4.
Does anybody know any softwares to convert them? I have used Pano2Movie, but it seems my trial version is already outdated, so I can't use it again.
You should try QTVR2MOV
(Sorry, missed the part, where you mentioned you had Pano2Movie already)

I would like to implement zip decompression without using external frameworks. I think that Compression framework from iOS SDK should be ok for this, but I'm not sure. I was looking for some examples on how to extract files using this but found nothing. I wan't to extract all files from zip to some directory (not Data object). Can someone help me starting this? Maybe some tutorials I haven't found? Any help will be appreciated.
zlib, which is already there, provides the raw decompression and CRC calculation engines. From there you can write your own code to interpret the zip file structure, which is documented in the PKWare appnote. It is relatively straightforward.
I want to decode a file that has the extension .pwi but I am not having any luck at all. It looks like white squares and other characters.. An example is down below. I really want to decode it, I have searched Google now for hours but still can't find the solution.. Decoding it to Hex, MD5 or whatever Google says I have to do doesn't work. I know that it's from my notes on my old Windows phone. But I don't have one anymore.
I am looking to encode a jpg sequence into an mpeg format on an iphone project I am working on. My google searches are coming up pretty short. Does anyone happen to know of a library that would let me do something like this?
have a look at ffmpeg
(more characters required)
Hope You all are fine and also in one of your best of moods!!
Hope You all are Enjoying iPhone development.
I herewith one issue that i am not able to solve, may be i don't know the depth concept of iPhone.
So Its my humble requet to you to guide me or suggest or share your ideas.
I do find an issue with getting an image from Bytes array.
I am calling a webservice which returns an image in form of Bytes Array as response.
I have Converted this bytes array in to form of NSData, Now i have NSData, But When i Try to get an image from this NSData, It shows nil.
I Did lots of R&D and Find one suggestion to use base64 encoder, But unfortunately because of not proper guidance I was not able to Implement that.
I was also suggested to use OPenSSL Library for base64 from url http://www.cocoadev.com/index.pl?BaseSixtyFour
But again i was not able to include #include #include these two files. as in Newer Version of SDK 3.X family Apple has depreciated those (as i guess).
So Now i need help from you guys. kindly help me if you have solution or if you know the steps to solve these.
Looking Forwards.
Regards,
Arun Thakkar
Using OpenSSL on the iPhone seems like a very heavy-weight solution if all you need is Base64 encoding/decoding. Look at this post for how to use a category for NSData to add base64 encoding/decoding. You want the second section of this blog post as the first deals with OpenSSL :)

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.
