Understanding avconv console output-Collection of common programming errors

I’m using avconv to broadcast a video on justin.tv from my Raspberry Pi.

I get it (weakly) working a very few times. Most of the times justin.tv is not being updated and says “disconnected”.

The command is:

avconv -f video4linux2 -s 640×360 -r 10 -b 350k -i /dev/video0 \
-f flv rtmp://live.justin.tv/app/live_520myKey

After transmitting a few frames my console keeps printing:

frame=    3 fps=0 q=2.0 Lsize=79kB time=8043.93 bitrate=0.1kbits/s dup=0 drop=1 
frame=    3 fps=0 q=2.0 Lsize=79kB time=8043.93 bitrate=0.1kbits/s dup=0 drop=2
.......
frame=    3 fps=0 q=2.0 Lsize=79kB time=8043.93 bitrate=0.1kbits/s dup=0 drop=4000

Frame number does not change but drop keeps increasing.

Does this mean:

1. The video stream is not created/crashed (by some webcam/system) fault?
2. The video stream is not transmitted due to some problem with my internet dongle (e220)?

What I understand is frame number 3 was not transmitted and avconv is trying to transmit it repeatedly. Some times this is 3…some times 6…10 like that and it stops there and just repeats increasing the drop=xx number.

Can you please tell me what’s happening here?
