iPAD Streaming video to a ffmpeg server. front facing camera
6 décembre 2011, par IrishGringoThis is a video chat type program.
My project is to write a native ObjC app that will stream video from the front facing camera to a server. This server will format and relay to be sent to another location.
In a related question, I want to display video streaming from the server. The video server will probably be running ffmpeg for formating.
But this question is just asking advice for the iPAD project. I wanted to get comments about issues I need to be thinking about.This is my strategy :
I was thinking of using AVFoundation framework to stream from the cam to a URL server. I don't know if I will be formatting on the client or no, so some comment there would be interesting. http://developer.apple.com/library/mac/#documentation/AVFoundation/Reference/AVFoundationFramework/_index.htmlFor streaming the video, I was going to be using :
http://developer.apple.com/library/IOs/#documentation/AVFoundation/Reference/AVCaptureSession_Class/Reference/Reference.html#//apple_ref/occ/cl/AVCaptureSessionso if someone has some ideas/suggestions... extra code I can look at. I would appreciate it.

Video upload size
16 mai 2014, par Jonas mI’m having a hard time figuring this one out, so hopefully, some of you who has tried this before, will take the time to reply and share your knowledge.
I’m working on a site, which after release, will be feeded in the television and other commercial places. The site asks the user to upload a video with a story, and we expect alot of people to do so.
My problem is the whole storage/space talk. A normal, unencoded iPhone recording easily fills around 100-120 MB for a minute or two.
I’ve tried setting up and using FFMPEG to re-encode the movies, but the problem is, that one encoding sucks up 100% of the CPU, leaving the site inaccisible for anybody else.
Is there anything you could suggest, which would be sufficient for such a site ? The client is on a budget, so price is a consideration aswell. Best of all would be a free alternative to etc. FFMPEG, but with less CPU usage.
My specs are as follows
CentOs 6 on a
1GB ram DigitalOcean cloud service with nginx + php-fpm and mysql.Im hoping for some cleaver folks to answer this !
Thanks in advance.

How to utilize hardware decode for audio ?
20 mars 2014, par jAckOdEI have a buffer that contain packets read by ffmpeg from a video file encoded using H264/AAC
According to Apple document, audio stream encoded in AAC can be decode with hardware support,how to decode the audio stream with hardware support ?
UPDATE : I use Audio Queue Service to output the audio. Right now i decode AAC packet using ffmpeg and send LPCM audio to AQS. According to the Apple document, I can send directly AAC audio to AQ and it will take care of decoding task. Does it decode with hardware ? Do i need, and how to set Audio Queue's parameter to enable audio hardware decoding ?
