I try to create video stream with ffmpeg and ffserver. I would like to use flv or mpeg1video encoders because looking at local ffmpeg alone those encoders provide pretty decent speed.

But when I try any of them with ffserver I get either "rc buffer underflow" error (when bitrate is smaller) or "HTTP error 503 Server too busy" (when I increase the bitrate to avoid the first error).

Is there some magic option which allow me to pass data to ffserver and avoid those errors?

My current config:

<Stream live.ts>
Feed feed1.ffm
Format mpegts

NoAudio

VideoCodec flv
VideoSize 600x600
VideoFrameRate 30
VideoBufferSize 5

AVOptionVideo flags +global_header
AVOptionVideo qmin 2
AVOptionVideo qmax 56
PreRoll 5
StartSendOnKey
VideoBitRate 1000
</Stream>

FFServer returns 503 Server too busy when the bandwidth is exceeded. You can check the bandwidth usage on http://localhost:8090/stat.html (assuming the server is on localhost).

If you want to increase the bandwidth, just change the MaxBandwidth setting at the top of the config file, before the streams and feeds.

For example

MaxBandwidth 10000

sets a 10 Mb/s bandwidth, which should be more than enough for your stream.
