Making a native website iPhone app (converting a website to an iphone app) I want to stream this rtsp link: rtsp://67.85.223.199:110/cgi-bin/rtspStream/1 (there is no file extension I don't know why) if you enter that as a url on quick time it works. I can't embed it correctly for the iphone for it to work. I figure if I can stream it to a browser without active x it should be compatible for the iPhone. Tried a bunch of way to do this, hoping someone out there as the answer :)

Judging by your URL, you are streaming with an IP camera. That can easily be restreamed to iPhone, Flash players, Android, anything, really. You may need to make sure your camera can stream H264 and AAC if you want audio. Our company is doing something similar with NetroMedia. http://www.netromedia.com/

Firstly, as this is essentially a multi-disciplinary question, please feel free to submit answers which only answer one part of the post - I will upvote answers which satisfy any of the questions below.
Hi, we are putting together an installation in which:
Audio comes in through a microphone to an FM transmitter
Transmitted to receiver
Receiver is plugged into computer's Line In
Audio is recorded/streamed as an .m3u stream, or recorded, and then uploaded(?)
Stream is accessible by scanning QR code on iPhone/Android.
I have a few questions around the subject that I was wondering if people could help with.
This is kind of a minor first question, if you are able to answer the second question, but is the best way to deal with incoming audio to record it 'before' uploading it, resulting in a delay, or is it to stream it?
I'm not sure of the best way to host the upload, as I suppose that it would be either an .m3u stream or some kind of progressive .mp3 that would need to be uploaded somewhere that supported this. Any advice? Is this kind of thing possible with free webhosting solutions? It would preferably be above 128kbps, too.
Initially, I presumed that the easiest way to have an audio stream linked to a URL that allowed for QR code linking was to build a very simple webpage with a media player on it, so that the end user wouldn't have to download any external application, and it could be done through the Android/iPhone browsers. Is this the case? Is the easiest way of doing this with something like <video> or <audio>, or is the HTML5 support for the mobile browsers not yet good enough? What are the alternatives? Something like jPlayer looks like it would work?
Thank you for your responses, I can give any necessary technical information you may find relevant, but these are quite broad questions. We can run the stream from either OSX 10.7 or Windows 7, as we have both, so recommendations for suitable software for either platform are welcomed.
Thanks again!
EDIT: Information from jPlayer.org -
HTML5 Audio Streams
HTML5 browsers and their support for audio streams. (Note that, jPlayer's Flash fall-back for non-HTML5 browsers works with MP3 streams.)
Audio streams work on:
Firefox (OSX, Win): OGA
Safari (OSX): MP3
Mobile Safari (iOS4 iPad/iPhone/iPod): MP3
Opera (OSX, Win): OGA
Chrome (OSX, Win): MP3, OGA
IE9 (Win): MP3
No mention of iOS5 or Android, but I used my android phone to check out the jplayer 1.2 stream demo they have up on their site, and it works. Seems like this could be the answer, but I need to know a little more about hosting, and perhaps iOS5 compatibility, though I'm sure it must work going forward. Anyone?
I recommend going with a standard SHOUTcast/Icecast setup.
First, you need an encoder. I recommend Edcast if you're doing this under Windows. The encoder is responsible for listening to your sound card, and encoding/compressing the raw PCM data into MP3, or whatever format(s) you need.
Next, you need a server. Again, SHOUTcast or Icecast will work great for you. No, you typically cannot host this on any free web hosting provider. Fortunately, hosting for SHOUTcast streams is cheap, and readily available. You can also host the server yourself, if you have the necessary bandwidth. It doesn't take much CPU/RAM.
Finally, you need a player. Your jPlayer will work just fine. For iOS, I usually just link to the playlist file and let it play. On Android, you can do a Flash player. HTML5 compatibility is there though, and jPlayer would be the way to do it.
Also note that there is no such thing as a ".m3u stream". A .m3u file is nothing but a playlist file, that contains the URL to the streaming audio. That's all.
For the QR code, just link to a web page URL that contains your player. That's all you have to do.
If you have more specific questions as you go, you should post them as separate questions here.
I'd like to stream video from the camera on an iOS device to a receiver via wifi, in effect turning the device into a wireless webcam. Is there a way to build a small app that captures video input on an iOS app and sends it via an RTSP stream or similar?
As this is an ad hoc experiment, I'm not concerned about App Store guidelines and can jailbreak if necessary.
If I interpret your question correctly you more or less need to solve four problems:
Get the camera feed.
Convert/encode this to the right format.
Stream the data.
Prevent the phone from locking itself and going into deep sleep.
The first one is fairly simple and Apple has as always provided good documentation and examples -> API link. Make sure you check out their example in the end as you will get a CMSampleBufferRef data object back.
For the second and third part, you should check out the CFNetwork framework and specially CFFTPStream for streaming using FTP.
If your are only building this for yourself then you can always turn off the Auto-Lock feature in the settings. If you on the other hand would like to distribute this to other users you could use a trick to play a mute sound every 10 seconds. This is more or less how all the alarm clocks work in the App Store. Here's a tutorial. =)
I hope I helped a little bit at least.
Good luck and best regards!
I'm 70% of the way to doing the same thing. Here's how I did it:
Capture content from video input
Chop video into files for use in HTML Live Streaming.
Spin up a web server on the iPhone and make the video files available.
Connect to the IP address of the phone and viola! you've got live streaming video.
Last time I touched the code I was trying to debug my Live Streaming not working. I'll try and get my source code posted on github this weekend, if you'd like to take a look.
I am building this iphone app for a client and they have a large set of flash video files that they need to play/stream to the iphone. I understand that the iphone doesnt natively support flv playback but isnt there anything I can do to get around this problem?
In case it helps, they are using the akamai flash player on their website to play these video files.
Thanks in advance.
Yes! - You can convert all the videos to m4v format.
There's a javascript hack available, but it will only work if it's installed on the clients web server. It's also pretty clunky and slow and will likely murder battery life.
A workaround, since you're working with video, is to convert to mp4 format.
Short answer: no flash, but conversion will do what you need.
akamai actually supports "auto-packaging" of h.264 content which may be your best option here. By uploading 1 or more h.264 files you can use those to both serve your Flash player, and akamai will also auto-package them for iPhone (chunking them into .ts files and creating an .m3u8 reference file for dynamic mobile streaming).
This allows you to not have separate encodes for mobile and web, thus saving money and time so you can leverage your existing archive.
I have run into a bit of a problem. I built an iPhone app that streams my podcasts via the MPMoviePlayerController. Apple will not approve it because it can use too much bandwidth over the Carrier Network. So their workaround is to use a Stream Segmenter. I am unable to install a stream segmenter on my server. Are their ANY other solutions people have come up with that can help me stream my podcast to iPhone devices? Even if I have to make it a Web Application as opposed to a native application.
Thanks,
John
You could use a simple service like Encoding.com to create iphone segmented ondemand versions of your files for multi bitrate adaptive playback. You could also provide a high and low quality and only display the high when the reachability class shows that your using wifi. I had to do the second option to get one of my apps to pass approval. Hope this helps!
Well if you don't want a native app, I think you can just put a video link on a webpage and when the user clicks it Quicktime will take over and play the file. It will play the file as it downloads it.
I don't have any experience streaming large files over the iPhone, so I can't help guide you on alternatives and keeping it a native app.
I am working on an application that will stream music from a server of mine from an iPhone application.
This is my first iPhone app so I am a bit confused :
What would be the best way to do
this?
Is there something already built in
that I could use, like a MP3 player
that I just need to point toward the
correct server?
Do I need a streaming server to do
so?
I'm relatively new to Objective-C/Cocoa (touch), but I have read an article on the cocoawithlove site titled "Streaming and playing an MP3 stream" and tested the sample code on my iPhone and it works perfectly. I don't know about the licensing or anything, if you would be able to use it, but I'm sure someone or even you can figure that out.
Sorry again for not being able to provide any more information or even a link. This is my first answer on SO and cannot post hyperlinks :(
