Hi Tiago, I've added negotation to receive H264 streams,is it interesting for you? Tell me your problem and if it's possible I can help you. Emanuele Bottegoni

It would be very nice to see an official video support inside PJSIP. Videoconferencing it's now quite a common stuff, and basically it's simply an additiona RTP stream? emanuele bottegoni wrote: > Hi Tiago, > > I've added negotation to receive H264 streams,is it interesting for you? > Tell me your problem and if it's possible I can help you. > > Emanuele Bottegoni > > > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >

Hi; Did you able to start two way stream with 264 . I have some port issues .. video stream is using audio streams port.. i will be handling it soon i guess.. and what are you using for displaying stream , ? VLC or ffmpeg .? muge On Thu, Oct 9, 2008 at 4:27 PM, Perry Ismangil <perry@pjsip.org> wrote: > emanuele bottegoni wrote: > >> Hi Tiago, >> >> I've added negotation to receive H264 streams,is it interesting for you? >> Tell me your problem and if it's possible I can help you. >> >> Emanuele Bottegoni >> >> >> > Hi Emanuele, > > Certainly, adding video support is always interesting.

Hello all, Thanks for your responses. My Idea is to make some kind of videoconference. It should be signaled with SIP, and stream via RTP. I'm able to capture video using directshow libraries, and it would be great to use transport functions of PJSIP to do the rest. What do you think?

Hello everyone, I'm using VLC for video streaming in pjsip. I haven't completely finished it yet but i can now make some video calls between PCs. In the callback on_call_state() in pjsua_app.c when i get an incoming call i check if it has video media. I do this by grabbing the local_sdp and remote_sdp using call_id, acquire_call, pjmedia_sdp_neg_get_active_local(), pjmedia_sdp_neg_get_active_remote(), etc. I also had to change a few things in negotiating SDP's. If i have video media i just grab the remote IP and port number out of the remote_sdp, put these values in the commands buffer for VLC and start playing from remote stream and streaming off my webcam using the VLC functions: VLC_Create(), VLC_Init(int, int, char **s), VLC_Play(int), VLC_AddIntf(int, char *s, int, int), VLC_Die(), VLC_CleanUp(), VLC_Destroy(), VLC_Pause(int), VLC_Stop(int), VLC_FullScreen(int). It works fine but as soon as I get two video calls up on my PC my CPU usage jumps really high and stays there for the duration of the two calls. Is it because I'm using the wrong type of video codec? I'm currently using H264. Any ideas would be greatly appreciated.

Hi Hubert; Haven't you created another stream for video ? As far as i understand after SDP negotiation you get if there is video stream or not... This is my OK answer form pjsip to another sip client m=audio 4000 RTP/AVP 3 a=rtpmap:3 GSM/8000 m=video 4002 RTP/AVP 98 a=rtpmap:98 H264/90000 a=recvonly Everything seems pretty. But after streams are created Pjsip mixes the ports with audio and video and it all crashes ... How is your point of view to audio and video streams in your application.

Hi Mugo, No i don't create another stream for video. I just make sure the port ranges for audio and video don't overlap. For example for audio i do the usual pjsip thing, start the port range at 4000 and with a maximum of 32 calls it'll go up to 4063. For the video i've got a config file that pjsua_app.c reads at startup. In there i specify what port video should start at. And i usually put it at 6000. When the application runs it checks if those ports are free or not and starts using them. This way my audio and video ports don't overlap. When i create my SDP, and before i send the offer, the initial port for video is the one that i specified in the video config file. After having sent the offer and read the incoming remote_sdp, what i pass to VLC is just the port number to transmit to, IP address to transmit to, transcoding codec, video bit rate and the mux type. I pass it to the commands buffer of VLC and use the functions VLC_Create(), VLC_Init(int, int, char **s), VLC_Play(int),VLC_FullScreen(int), etc... So to answer your question no i don't let PJSIP handle the video streams. I use PJSIP only for SDP negotiation that's it. I leave PJSIP to take care of all the audio streams and ports. And i keep the video part to VLC, including its transport and everything else. PJSIP doesn't touch that part. I can see you're using H264. I am too. Did you ever have two incoming H264 streams on your PC? How was your CPU usage?. When i have more than one on my PC my CPU usage doesn't look too good..

Hi Hubert; Actually my implementation is quite different from yours. I want pjsip to stream h264 from one side to other.. You choose VLC to do it.. I changed pjmedia_session_create and pjmedia_stream_create functions as well as SDP negotiation. I want vlc to decode this h264 stream with file.sdp which includes remote ip and port information with codec. Did you install Microsoft Platform SDK for direct show headers ?

Hello Muge, Yes my implementation sounds different. I guess i took the easiest and quickest way to get video working. I do write the file.sdp file just like you and get VLC to read and decode the sdp file, but i also use VLC to stream. To answer your question yes i did install Microsoft Platform SDK... Hmmm... i can't remember which version though. Quick question. Since you are already using VLC to decode, why not use it to stream as well? You won't have to take care of streams, ports, transports, etc... It might be easier for you. I mean you are already using VLC to decode, might as well use it to encode. Makes your life easier. Maybe i'm missing something that you want to accomplish. What do you think?

Hi Hubert; I do understand your curiosity :) Yes it seems meaningless .. But my aim is not only succeeding pjsua to pjsua calls.. i want to have video calls between pjsua to other software clients and voip phones.. They use their hardware or software h264 encoding and transmitting through rtp or srtp stream to pjsua .

Hi Muge, Oh that tutorial. Yeah i started off that tutorial. My implementation of video is very very similar. I use the commands buffer, VLC_Create(), VLC_Init(), VLC_ADDINTF(), etc. But i found the guide a bit too complicated/confusing and overloaded for what i wanted to do. Especially his definitions in the vlc.h file. Don't need all that. What i do is just get the remote IP, port, codec from remote_sdp and use a couple of VLC functions to stream and decode. Done. That tutorial i found was too much for what i simply wanted to do. Plus, i was never good at spanish. ;) Hubert On Wed, Oct 15, 2008 at 5:27 AM, P.Muge Ersoy <muge.ersoy@gmail.com> wrote: > Hi Hubert; > > I have a question for you .. > > Did you use the below tutorial for vlc display inside pjsip? > http://wiki.videolan.org/LibVLC_Visual_C > > > Muge > > > > On Tue, Oct 14, 2008 at 12:51 AM, Hubert Langevin <hubertlangevin@gmail.com> > wrote: >> >> Hello Muge, >> >> Yes my implementation sounds different.

yeah i am not getting anything also.. may i ask which version of vlc you are using?

Hi Muge, Yeah that's why i didn't follow that guide. It's got some good tips on which functions you use but the whole thing is a bit too confusing for me and just didn't work for me. I am using the old version of VLC, i'm not sure how to call it. It's at this link below. Again the old version is simple for what i want to accomplish. http://www.videolan.org/developers/vlc/doc/doxygen/html/group__libvlc__old.html I was reading what you mentioned earlier, about the fact that you want video calls between pjsua to other software clients and soft phones/ VoIP Phones. Can't you do that already using VLC both ways? I mean for video calls all you need is modify your outgoing SDP so it contains video media at a certain port that you specify at startup so the remote video phones can read it and you read their corresponding SDP and start one instance of VLC that reads and decodes at the same time. I do that using VLC_AddIntf() for multiple video streams incoming and outgoing. The audio is still handled by pjsip during that same sdp exchange and the video by vlc. For any re-invites, for example change of remote video port or remote video codec, just destroy the vlc instance in on_call_media() callback and re-create it using the new values from the re-invites. I mean it is still a video call that i make to other video phones. I did a test from my pjsua to an eyebeam (x-lite) video phone and everything was fine. Audio was fine and video was showing as well. Actually video was very pixelated, even though I did specify H264 from Eyebeam and pjsua. Maybe eyebeam and videolan have different implementations of H264 i'm not sure. But video calls between pjsua <===> pjsua works perfectly. And VLC does support SRTP from what i've seen. I'm using pjsua too. Are you using libvlc.lib and libvlc.dll?

Hi Hubert; I tried your way of vlc video call.. I guess the problem at your cpu is because of loading to many dll ( vlc and plugins) during the call.. My computer was forced also.. I am using VStudio so i am using libvlc.dll... actually i ve tried to make .def filen and convert libvlc.lib but lib didnt work.. I guess it was because new api of vlc.. Did you code to get SDP information from pjsua_app.c or is there any Pjsua api to get active sdp information ? muge On Wed, Oct 15, 2008 at 2:07 AM, Hubert Langevin <hubertlangevin@gmail.com>wrote: > Hi Muge, > > Yeah that's why i didn't follow that guide.
