[Live-devel] RTP PCMU-audio and H263-video problem?

[Ganesh V]

Hi Wei Su,

>From your query, it appears that you are trying to add multiple media sub-sessions to a media sub-session. There is a previous post on the same topic. Kindly refer to http://www.mail-archive.com/live-devel@lists.live555.com/msg03995.html for the same.

Please let me know if this helps or you still face problems.

Cheers,
Ganesh

P.S: I haven't looked at the latest code in Livemedia. Pardon me if there are some changes to the same as compared to my earlier post.

hi *Ross:*
*I need some help!
*
*I recently use live555 to implement a RTP streaming relay, I have to relay
PCMU-audio and H263-video from a media server to RTSP client,*
*when I only relay PCMU-audio or H263-video it works ok, but when i want
relay both of them it works weird,*
*it can send aduio in 2 seconds, and then re-cache the rtp streaming, then
the audio can't be send
*
*, but video works well. I am sorry my english is not good.*
*this is frame work of my PCMU-audio  relay:*
*1. I use SimpleRTPSource::createNEW() to get the RTP streaming.*
*2. I use SimpleRTPSink::createNEW() to create audioSink.*
*3.I use audioSink to play audioSource. *
*and it works well.*
*
*
*this is frame work of my H263-video relay:*
*1. I use SimpleRTPSource::createNew() to get the RTP streaming.*
*2. I use H263plusVideoStreamFramer::createNew() to create video source.*
*3. I use H263plusVideoRTPSink::createNew() to create video sink.*
*4. I use videosink to play videosource.*
*an it works well.*
*
*
*but after relay both of them. it woks weird.*
*1. ServerMediaSession* sms = ServerMediaSession::createNew(*env, 8554).*
*2. RTSPServer* rtspServer = RTSPServer::createNew(*ene, 8554).*
*3. sms->addSubsession(PassiveServerMediaSubsession::create(*audiosink,
audioRTCP)).*
*4. sms->addSubsession(PassiveServerMediaSubsession::create(*videosink,
videoRTCP)).*
*5. rtspServer->addServerMediaSession(sms);*
*6. audioSink->startPlaying(*aduioSource, afterPlaying, audioSink);*
*7. videoSink->startPlaying(*videoSource, afterPlaying, videoSink);*
*
*
*
*
