[FFmpeg-user] Feeding DVR to ffserver

[Alex Povolotsky]

Hello

I'm working with pretty aged video recorer for surveillance cams, trying
to connect it to zoneminder instead of weird propiertary surveillance soft.

tanidvr gets video stream, but all attempts to send it to ffserver
failed so far.

=== ffserver.conf ===
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 200K
ACL allow 127.0.0.1
</Feed>
=== ffserver.conf ===

than

# /usr/local/bin/tanidvr -m 1 -c 1 -m 1 -t dvr1 -u admin -w admin |
ffmpeg -i - -vcodec h264 -r 1/30 -f lavfi -i aevalsrc=0 -c:a libmp3lame

I'm new to video processing and maybe I'm doing lots of dumb errors, but
googling for error yielded nothing meaningful.

What should I do to feed ffserver with video and what are good codec
params to compress the video?

Where can I find good introduction for video processing with ffmpeg?
