IP CAM RTSP re-streaming adding audio

[cruisher]

Hi All!

I have an IP camera,the camera RTSP stream does not contain any audio stream. I would like to add audio to the IP camera RTSP stream from a microphone connected to the sound card, then re-stream this new stream to a wowza server.
I'm using VLC on windows 7 os. How can i do this?
Thank u for your help!

Basically, you can't do that. There would be no way to synchronize the video with the audio signal.

Thank you for your answer!

Hi, sorry to bring this up again.

Is this possible now with the newer version of VLC? Same question as OP, is it possible to restream a RTSP stream using VLC and adding an audio track via "mic in" input on the PC?

RTSP (Video only) ----> VLC + MIC IN or LINE IN ----> RTSP (Video and Audio)

Because both streams are "live", I would assume video and audio would be captured synchronized and then restreamed. Thanks in advanced.

It depends if your audio is synchronized in VLC. Usually, this is not the case.

Thanks Jean.

Can you let me know how to add the "mic in" option when i'm at the "Network" tab under "Stream" menu? I can try this out and post back my findings.

Edit: found it but i can't get it to work properly. I get black screen and audio ticking when streaming from the network but when i stream on the local machine i see picture but can't confirm audio because I am remoting to it.

:sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://:554/test} :sout-keep

Anybody know why I can't even get video to show?

Hello All,
same problem : i need to restream in rtssp an rtsp video source (rtsp://) with a directshow "usb microphone"....

tried :
C:\Programmi\VideoLAN\VLC\vlc.exe -vvv -I rc dshow:// :dshow-adev="USB Microphone" :dshow-vdev="None" :live-caching=300 :network-caching=1000 :input-slave="rtsp://192.168.0.10:554/user=admin&password=XXXXXXX&channel=3&stream=0.sdp?real_stream--rtp-caching=100" :sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://:8554/test.sdp} :sout-all :sout-keep ttl=128

and this work with audio but NO VIDEO.

tried :
start C:\Programmi\VideoLAN\VLC\vlc.exe -vvv -I rc dshow:// :dshow-adev="USB Microphone" :live-caching=300 :network-caching=1000 :input-slave="rtsp://192.168.0.10:554/user=admin&password=XXXXXXX&channel=3&stream=0.sdp?real_stream--rtp-caching=100" :sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://:8554/test.sdp} :sout-all :sout-keep ttl=128

and this work with audio and Directshow WRONG video (another capture device in my pc and not rtsp source)

tried also :
start C:\Programmi\VideoLAN\VLC\vlc.exe -vvv -I rc "rtsp://192.168.0.10:554/user=admin&password=XXXXX&channel=3&stream=0.sdp?real_stream--rtp-caching=100" :live-caching=300 :network-caching=1000 :input-slave=dshow:// :dshow-adev="USB Microphone" :sout=#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://:8554/test.sdp} :sout-all :sout-keep ttl=128

and this work with rtsp video but not USB Microphone Audio.....
and give me [00e1e164] main input error: demux doesn't like DEMUX_GET_TIME always in loop

Someone have a solution ? Tried also to search unsuccesfully a free "directshow rtsp capture device" to have only direct show source....

Thanks a lot
Dario

Unfortunately, this is a VLC limitation, when the 2 sources are missing timings.
