Replying to [comment:3 importinis]:
> In http://ffmpeg.org/ffserver.html#toc-Description I see, that
"ffserver is a streaming server for both audio and video. It supports
several live feeds, streaming from files and time shifting on live feeds
(you can seek to positions in the past on each live feed, provided you
specify a big enough feed storage in ‘ffserver.conf’)."

> So ffserver is streaming server not encoder, so why to ignore servers
params? In this case, params related to streaming server(ffserver) should
NOT be ignored. Maybe you have an answer: How to set Preroll,
StartSendOnKey in -override_ffserver ? I cant find any option.
AFAIK {{{Preroll}}} and {{{StartSendOnKey}}} should be settable even with
{{{-override_ffserver}}}.
{{{-override_ffserver}}} only affects encoding parameters (which are
usually set by ffserver when sending the header to ffmpeg). So for example
AVOptionAudio/Video options will be ignored by ffmpeg when you set the
option, and you will need to specify the corresponding option in ffmpeg.
Now, simple question since I started to look at ffserver yesterday, how
can I reproduce the !Preroll/StartSendOnKey issue? What should I expect,
what happens instead?
