Trying to combine two RTP streams...

[batrick]

Hi,

I'm trying to combine an audio stream and a video stream using:

Code: Select all

cvlc --ipv4 screen:// --screen-left 0 --screen-top 0 --screen-width 1920 --screen-height 1200 --screen-fps=60 :input-slave=rtp://127.0.0.1:46998 --sout '#transcode{venc=x264{keyint=60,idrint=2},vcodec=h264,vb=3000,acodec=mp4a,ab=32,channels=2,samplerate=22050}:file{dst="/home/batrick/foo.mov"}'

The input-slave rtp stream is just audio (from PulseAudio actually; this is a huge workaround because I can't get :input-slave to work with alsa or pulse).

The above command seems to execute fine but it quickly consumes all of my system memory (there's a bug in there somewhere?). Any idea what's wrong? Is this command even going to do what I hope?

If I do this, the audio works just fine:

vlc rtp://127.0.0.1:46998

I believe you can't sync RTP and screen capture. They do not use consistent timestamps.

Unfortunately, I have not had time to write a PulseAudio input, and nobody beat me to it either.
