[FFmpeg-devel] [RFC] ffserver stream checks
Thu May 20 16:03:31 CEST 2010
I was thinking it would be a good idea for ffserver to rewrite the ffm header
of its feed file based on what actually got used by ffmpeg. Ran into an issue
with the audio codec frame size, since it won't be known until the codec is
actually opened. So I've also dropped the check of the frame size for the
Likewise, it would be nice to be able to have a single stream definition that
works with whatever frame rate the source video used, so I've removed that
check as well. I'm looking for feedback on any downsides to this approach.
Ideally I'd like to be able to run an ffserver stream definition with
essentially the behavior of "-vcodec copy -acodec copy" but currently there
doesn't appear to be any way to express this in ffserver.conf. Also I'd like
to be able to treat the ffserver config as more of a template, and allow the
ffmpeg commandline to override some of the settings, or at least fill in
missing ones. Currently it looks like whatever ffmpeg receives from ffserver
completely replaces all of ffmpeg's option settings. Suggestions?
