Re: [Linphone-developers] how to use mediastreamer2 tutorial program-- mediastream.c

[Wu Shan]

Hi,

       I figured out that if I want to make example program, mediastream work, 

I should issue command at two different machines:

Machine A  ./mediastream --local 5010 --remote 10.10.104.199:6014 --payload 110

Machine B  ./mediastream --local 6014 --remote 10.10.104.198:5010 --payload 110

thus these two machines should have an rtp session with codec speex_nb[1] then machine A and B 

should be able to talk to each other. 

reference: http://blog.sina.com.cn/s/blog_59d649610100diua.html

[1] payload type index is set by function rtp_profile_set_payload( ) defined in payloadtype.h 

        rtp_profile_set_payload(&av_profile,110,&payload_type_speex_nb);

        rtp_profile_set_payload(&av_profile,111,&payload_type_speex_wb);

        rtp_profile_set_payload(&av_profile,112,&payload_type_ilbc);

        rtp_profile_set_payload(&av_profile,113,&payload_type_amr);

        rtp_profile_set_payload(&av_profile,114,args->custom_pt);

        rtp_profile_set_payload(&av_profile,115,&payload_type_lpc1015);

#ifdef VIDEO_ENABLED

#if defined (__ios) && defined (HAVE_X264)

        libmsx264_init(); /*no plugin on IOS*/

#endif

        rtp_profile_set_payload(&av_profile,26,&payload_type_jpeg);

        rtp_profile_set_payload(&av_profile,98,&payload_type_h263_1998);

        rtp_profile_set_payload(&av_profile,97,&payload_type_theora);

        rtp_profile_set_payload(&av_profile,99,&payload_type_mp4v);

        rtp_profile_set_payload(&av_profile,100,&payload_type_x_snow);

        rtp_profile_set_payload(&av_profile,102,&payload_type_h264);

        rtp_profile_set_payload(&av_profile,103,&payload_type_vp8);

  Please let me know if I understand it in a wrong way. Thank you very much !!

Hi all, 

         I was trying to learn how to use mediastreamer2 library to make an easy

rtp program to send and receive the rtp packet. Based on the usage instruction, 

I issued command

#less /proc/asound/cards 

and figured out my sound card's name is  ENS1371

then I run the program with following input command:

#sudo ./mediastream --local 222 --remote TargetIP:222 --capture-card ENS1371

and it throws following ortp warning messages to me:

Remote addr: ip=TargetIP port=222

ortp-message-Mediastreamer2 2.8.2 (git: 2.8.2-120-g985da5a) starting.

ortp-message-Registering all soundcard handlers

ortp-message-Card 'OSS: /dev/dsp' added

ortp-message-Registering all webcam handlers

ortp-message-Webcam StaticImage: Static picture added

ortp-message-Loading ms plugins from [/usr/local/lib/mediastreamer/plugins]

ortp-message-Cannot open directory /usr/local/lib/mediastreamer/plugins: No such file or directory

ortp-message-ms_init() done

ortp-warning-no card with id ens1371

ortp-warning-cannot set noise gate mode to [0] because no volume send

ortp-warning-cannot set echo limiter to mode [0] because no volume send

Please teach me how to issue to correct command, so I can run this example program...

thanks in advance!!

                                                                                                                                           cheers!!
