Rc buffer underflow error when streaming from webcam

Asked By 10 points N/A Posted on -


I am having trouble with mp2v stream. I’m streaming from my webcam which gives an MJPEG video as output. After connecting the stream I get the following underflow error:

"rc buffer underflow"

This error leads to the application crashing every time. The only way I can prevent it from crashing is to either lower the video resolution to something very small like 320×240 or to increase the bitrate to something that’s very high, around 4000. I cannot afford such high bitrate on my bandwidth.

Can anyone please suggest a solution to my problem? I would ideally want the resolution of the video to be 640×480 with a bitrate that’s not bandwidth intensive.

Hi Ms. Preety, 

I'm sorry to hear that you are having problems with utilizing your webcam, hopefully the ff steps might help you out. 

Run a video (any video especially mpeg or mpg).

Look at the programs running on the fly (usually located with the icons near where the clock on your desktop is located- usually on the lower right hand corner)

you will most likely see a video converting program such as ffmpeg. 

Uninstall that program or disable it whenever you are going to use your webcam and you should be good to go. 


I hope I was able to help!
