Hi
I'm trying to stream audio file from rtsp using below command:
ffmpeg -re -i song.mp3 -f rtsp -muxdelay 0.1 rtsp://192.168.0.3:8554/live.sdp
But it is doing nothing. Can you please tell what I'm doing wrong?
Thanks Regards
Laxmi Khatri

Hi, I found solution for my problem. I made a fresh install of Blackmagic
drivers and got Decklink Video and Audio Capture on DirectShow devices
list. Now everything work as it should.

Subject: Re: [FFmpeg-user] Blackmagic Intensity Pro - how to capture video
with audio?
does it use a crossbar interface do you know?
there are some patches on ffmpeg-devel list [uncommitted as of yet,
sorry!] that might help...

Hello, I have Blackmagic Intensity Pro video card and I want to stream
video from that card to multicast using ffmpeg. But my problem is that
I can get only video from that card, no audio.
Ok, time for some commands.
List of my dshow devices:
-=-=-=-=-=-=-
ffmpeg -list_devices true -f dshow -i dummy
[dshow @ 04437720] DirectShow video devices
[dshow @ 04437720] Blackmagic WDM Capture - it is
Intensity Pro card
[dshow @ 04437720] DirectShow audio devices
-=-=-=-=-=-=-
As you can see Intensity Pro does not provide a separate DirectShow
audio device.
Blackmagic WDM Capture options:
-=-=-=-=-=-=-
ffmpeg -f dshow -list_options true -i video=Blackmagic WDM Capture
[dshow @ 043e7720] DirectShow video device options
[dshow @ 043e7720] Pin Video Capture
[dshow @ 043e7720] pixel_format=uyvy422 min s=1280x720 fps=50
max
s=1280x720 fps=50
[dshow @ 043e7720] Pin Audio Capture
-=-=-=-=-=-=-
As you can see THERE IS a pin called Audio Capture. But how I can
use it?
So here is my question: how I can map that Audio Capture pin as a
ffmpeg audio input?
I tried following commands (ffplay):
ffplay -f dshow -i video=Blackmagic WDM Capture - I can see only
video, no sound
ffplay -f dshow -i video=Blackmagic WDM Capture:audio=Blackmagic
WDM Capture - error: [dshow @ 02a8f480] Could not find audio
device.
Is it possible or Intensity Pro is not compatible with ffmpeg?

Cheers!
