Hi, I have started on an activity to get a basic Video call working on iPhone. It needs be be over RTP, preferably with H.264 codec. Has anyone written a video client with PJSIP specifically for the iphone? Are there any road blocks? ( I know PJSIP doesnt support video for now, but I plan to extend it - my question is more in the iPhone side). Prelim. analysis shows I can pass H.264 streams to the iphone media player framework and it can instantiate the appropriate player. My approximate plan is to send audio + video data using PJSIP, then extend PJSIP to support video decoding and pass the decoded H264 buffer to the media framework of iphone.

Hi, FYI we are also working on video and it is planned for the upcoming 2.0 release. Have a look at our roadmap in the trac site.

Hi Benny, 2.0 will be released on (01/01/2011)?

Hi Benny, Yes, I know PJSIP also plans to support it - but for this project, I cannot wait for that update, so I plan to do it myself. Since you may be ahead of me, I was curious if there are any restrictions in the iPhone APIs itself that will inhibit PJSIP (or any other stack) to not work with video. For example, it looks like I cannot use the Movie Player class as it expects a URL.For this to work, we will need frame/frame encode/decode and display support on the iPhone. thanks!

I also noticed that your roadmap says it will initially be for windows. My requirement is for iphone. I guess my question is not really a PJSIP question, but rather to developers who may have used PJ to make video work on iPhone - just wanted to check if it is doable or impossible today due to some iphone restriction :) On Sat, Dec 4, 2010 at 8:42 AM, Rob Wilkes <wilkrob@gmail.com> wrote: > Hi Benny, Yes, I know PJSIP also plans to support it - but for this > project, I cannot wait for that update, so I plan to do it myself.

Hello Rob We have implemented video call with PjSip 1.8.5 on iPhone. Best regards, Dima.

Hi Dima, I learned that the iPhone sdk does not publish the H.264 codec API, so developer can not use hardware decoder to decode raw H.264 stream directly, how can you do that? You decode video in soft way? Thanks in advance!

Now this is very interesting, Dzmitry. I thought I have to fiddle with iOS core media framework. So you are suggesting that I construct a UIImage from the raw decoded H.264 buffer and pass it to UIImageView for each frame? I thought this would be very slow, but I guess you've done it!

You could check it. Try to load array of images and renew UIImageView with images from array for different FPS. You could also try to play with image size and UIImageView size (fit image to screen for different orientation mode).

Dzmitry, I now have an iphone build for x264. Just as a quick clarification, I only need libx264.a - I can discard the ffmpeg and xvid libraries, right? Did you find any easy tutorial on how to use x264 libraries? As my first test, I am planning to write a small iphone program that just picks up some encoded frames in H264 and I want to pass it to x264 to decode as raw so I can construct and display an UIImage. Once I have that, I will integrate with PJ. X264 is completely new to me. thx On Sun, Dec 5, 2010 at 10:01 AM, Dzmitry Yablonski <grizlik@gmail.com>wrote: > You could check it.

Dzmitry- > Yes, we use x264 ( from http://www.videolan.org/developers/x264.html) > for decode h264. This is using the ARM core? I would think that using the ARM core instead of the media (DSP) core would overload the ARM and cut battery life.

Yes, once you have libx264.a built, you need to add it to your project and #include "x264.h". It provides you with x264_encoder_encode x264_encoder_decode APIs. But documentation seems very hard to find.....

Sorry, wrong statement below. I downloaded the H264 decoder from here: http://sourceforge.net/projects/p264decoder/ and created a wrapper in x264.h for it to make it look uniformed. It is not included as part of x264 it seems... Again, I have just reached a state where I can compile all of this stuff. Haven't actually dont the real check to see if it works. Maybe Dzmitry can throw insights.
