My command for my H.264 encoded web cam is :
 /usr/local/bin/.libs/lt-test-launch ( v4l2src device=/dev/video0
always-copy=false !
image/jpeg,width=1280,height=720,framerate=(fraction)30/1 ! rtpjpegpay
pt=26 name=pay0  alsasrc device=hw:1,0 ! audioresample !  
audio/x-raw-int,channels=2,rate=48000 ! audioconvert ! vorbisenc !
rtpvorbispay pt=97 name=pay1 ) 16200 192.168.1.170

When I use totem to play the camera its about 50/50 if I will get a
picture or not. I would think that being a "stream" of data if it cannot
decode the stream it would toss a bad frame or packet and wait for one
it can  decode.

If I connect again I'll eventually get a picture again.
how/what can I do to reliably connect to the H.264 encoded web cam?

Thanks - so much.

Jerry

Hello Jerry,

If I understand correctly your webcam outputs H264 encoded video data ?
If yes then you need to make some changes in the v4l2src element, so that it can support h264 caps on the src pad.

So your pipeline should look like this
/usr/local/bin/.libs/lt-test-launch ( v4l2src device=/dev/video0 always-copy=false ! video/x-h264 ! h264parse ! rtph264pay pt=26 name=pay0  alsasrc device=hw:1,0 ! audioresample !  audio/x-raw-int,channels=2,rate=48000 ! audioconvert ! vorbisenc ! rtpvorbispay pt=97 name=pay1 ) 16200 192.168.1.170

Best
Kapil
