[FFmpeg-devel] [PATCH]: Documentation: ffserver.conf -- 1 camera, flv format

[Piero Bugoni]

This is the third of seven pre-canned ffserver.conf
files I put together. I would like to include them,
and edit the ffserver.conf documentation somewhat,
around using them.

P.



----ffserver.conf-1cam-flv below----

# A tested-working ffserver.conf setup
# for one camera on a bttv card across
# 100Mbit capable testbench-LAN.

# Machine was a 1100 Celeron  with 512M RAM.
# ffserver and ffmpeg run on same machine with 
# apache webserver.   


# Global Stuff
#
Port 8090
BindAddress 0.0.0.0
MaxClients 10               # Probably safe, max =
1000
MaxBandwidth 16000          # 16 Mbit/s.

VideoBitRate 5200           # Experiment to get rid of
rc buffer underflow error. Max is 16000
VideoBufferSize 32         # Adjust in conjunction
with q and bitrate. 128 is a safe value
Format swf
VideoSize 352x288           # cif size 
VideoFrameRate 29.97
VideoQMin  3                # adjust bitrate with q
VideoQMax  3                #
NoAudio
</Stream>


# Notes:
#

# ffserver was run with this file, and the following
ffmpeg command
# on the same machine:
# 
# ./ffmpeg  -deinterlace -r 29.97 -s cif -qmin 3 -qmax
3 \
# -f video4linux2 -i /dev/video0
http://localhost:8090/feed1.ffm 
#
# Works with both firefox and IE. 
#
# When dealing with NTSC set frame rate to exactly
29.97 to 
# maintain sync.
#
# The Q	value is pretty important here. Values of
around 5 to 7.5
# give a reasonable compromise between stream width,
and image quality.
# make sure to match the settings in this file with
those on the command line. 
#
#
# Some additional settings: 
# Lower "Q" value means higher quality, but a fatter
stream:
#
# Qmin/Qmax=1, vbr~=12000, vbuf=52(min)
# Qmin/Qmax=2, vbr~=7100,  vbuf=33(min)
# Qmin/Qmax=3, vbr~=5200,  vbuf=22(min) good
quality/stream compromise
# Qmin/Qmax=4, vbr~=4800,  vbuf=21(min)
# Qmin/Qmax=5, vbr~=4000,  vbuf=19(min)
# Qmin/Qmax=6, vbr~=3200,  vbuf=13(min)

# Flash Player has a limit of 16,500 frames
# when using a browser refresh the viewing 
# page periodically


# How does adjusting these options from defaults
affect stream/quality 
# IntraOnly
# VideoGOPSize
