Hello,
any hints about the setup would be great. My aim is to stream with
ffserver webcam video which is delivered and encodey by ffmpeg.
Iam setting up ffserver with this config:
Port 8090
BindAddress 0.0.0.0
RTSPPort 5004
RTSPBindAddress 0.0.0.0
MaxClients 10
MaxBandwidth 40000
NoDaemon
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 5M
ACL allow localhost
ACL allow 192.168.0.0 192.168.255.255
</Feed>
<stream webcamvideo.mp4>
Feed feed1.ffm
Format rtp
VideoCodec libx264
VideoFrameRate 15
VideoBufferSize 40
VideoBitRate 500
VideoSize 640x480
# which value?
VideoGopSize 15
NoAudio
# i had problems with videostreaming with file. player said that
header were corrupted, so i used this config, but it doesnt help. i
still let it in.
AVOptionVideo flags +global_header
</Stream>
<Stream stat.html>
Format status
ACL allow localhost
ACL allow 192.168.0.0 192.168.255.255
</Stream>
<Redirect index.html>
URL http://www.ffmpeg.org/
</Redirect>
Starting the server with, which is working
ffserver -d -f ffserverwebcam.conf
Now I want to use ffmpeg to deliver the webcamvideo with
ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -an -vcodec
libx264 -vpre default -bf 5 http://localhost:8090/feed1.ffm
ffmpeg doesnt encode the video and ends with this output

Thats it...
ffmpeg is always telling me
[libx264 @ 0x2807500]broken ffmpeg default settings detected
[libx264 @ 0x2807500]use an encoding preset (vpre)
I put all libx264-*.ffpreset to [home]/[user]/.ffmpeg so ffmpeg should
find the presets. He will lookup to .ffmpeg-folder concatenate the
string of the ffmpeg params -vcodec with -vpre and with ".ffpreset",
so it should find a "libx264-default.ffpreset". But its still
complaining that it doesnt find it. But it runs, so I think its ok ?!
The next message is more problematic
Error while opening encoder for output stream #0.0 - maybe incorrect
parameters such as bit_rate, rate, width or height
ioctl(VIDIOC_QBUF
Any hints and help would be appreciated...
Thank you,
Ali Ayhan D.
