 ffserver is started with a simple config file (ffserver.conf) that defined
 only libx264 flv output and ffmpeg is started to feed the ffserver after
 which the error is received, which I don't know how to get around, because
 I don't know how to set "-vpre" or "-preset" in ffserver.conf file (when I
 try to set -vpre or -preset at ffmpeg's command line, I get the same error
 as provided here):

 ffserver.conf:
 {{{

 Generally, when I start ffmpeg only (without ffserver) no matter what
 libx264 options I give at cmd line, ffmpeg will fill out other (missing)
 options, like bitrate, width/height, etc with some default values. When I
 use ffserver with same ffmpeg cmd lines, I usually get this kind of "vpre
 error" mentioned above. How can I work around that error?

 Please help, thanks in advance.
