Pic in pic with videomixer but i haven't audio

[Ivan Bortolin]

Hi, i want make a pic in pic for conference's streaming.
I write this cose:

gst-launch -e  dv1394src ! decodebin ! ffvideoscale ! video/x-raw-yuv, width=320, height=240 ! mix.sink_0 videotestsrc ! video/x-raw-yuv, width=1024, height=720 ! mix.sink_1 videomixer name=mix sink_0::zorder=1 sink_0::sync=false sink_1::xpos=0 sink_1::ypos=0 sink_1::alpha=1 sink_1::zorder=0 ! ffmpegcolorspace ! jpegenc ! queue ! tcpserversink port=5000

and this work wery well, but how i can put the audio from the alsasrc in this streaming?
Thank

I try this solution.

gst-launch -e  dv1394src ! decodebin ! ffvideoscale ! video/x-raw-yuv, width=320, height=240 ! mix.sink_0 videotestsrc ! video/x-raw-yuv, width=1024, height=720 ! mix.sink_1 videomixer name=mix sink_0::zorder=1 sink_0::sync=false sink_1::xpos=0 sink_1::ypos=0 sink_1::alpha=1 sink_1::zorder=0 ! ffmpegcolorspace ! jpegenc ! mux. alsasrc device=hw 0 ! audio/x-raw-int,channels=2,rate=44100 ! audioconvert ! queue ! faac mux. avimux name=mux ! queue ! filesink location=vli.avi

But after 3 seconds i have this error:

gstbaseaudiosrc.c(828): gst_base_audio_src_create
(): /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0:
Dropped 12064 samples. This is most likely because downstream can't keep
up and is consuming samples too slowly.

What can i do? Thank

1.) aac in avi is not the best idea, use mp3 for avi or use aac in mp4
2.) look at your cpu load

Ivan,

Your latest pipeline didn't make sense to me. So I applied my handy debug wrapper and generated a few pictures of your pipeline. See attached. This helped me make some changes to fix the mux. My example replaces your DV source but you can plug that back in and it should fly.
