[FFmpeg-user] No luck with live stream from ffmpeg to ffserver

Discussion:

I haven’t had much luck deploying ffserver, nothing works out for me
streaming live from ffmpeg to ffserver. Had different problems, I don’t
know if my configuration is correct but, can’t really get ffsever to do
what I need and things are just frustrating me.

The last error message I’m getting is av_interleaved_write_frame(): Unknown
error along with Past duration too large. I’ve read somewhere saying that
it might be incompatible versions of ffmpeg, which I found odd and stupid.

I believed ffmpeg should work with any current version.

First, I’m trying to do a live stream using a capture card I’ve installed
and/or using VidBlaster but, haven’t been able. Audio can be done easily
but not Video.

Here’s my ffmpeg conf:

<Feed channel2.ffm>

File /root/channel2.ffm
FileMaxSize 64M
</Feed>
<Stream channel2.sdp>
Feed channel2.ffm
Format rtp
VideoCodec libx264
# VideoFrameRate 30
# VideoSize 640x360
VideoBitRate 1000
# Audio settings
AudioCodec libmp3lame #libfdk_aac
AudioSampleRate 41000
AudioBitRate 96
AudioChannels 2 #this is creating problem
# AVOptionAudio flags +global_header
MaxTime 0
AVOptionVideo me_range 16
AVOptionVideo qdiff 4
AVOptionVideo qmin 4
AVOptionVideo qmax 40
#AVOptionVideo good
# AVOptionVideo flags +global_header
# Streaming settings
PreRoll 10
StartSendOnKey
NoDefaults
</Stream>

When I send the feed to the server I get the previous mentioned error. What
exactly am I doing wrong? I’ve tried different combinations to send the
feed but nothing works, this is the last conf to send to the server:

Ffmpeg –re –rtbufsize 1500M –f dshow –I video=”input”:audio=”input” –acodec
libmp3lame –ar 44100 –ab 96k –vcodec libx264 –f flv
http://ip:8090/channel2.ffm

I've even tried feeding a video from my pc to the server, and still no luck.

Please guide me to the correct path to get this working, thanks.

Can someone please guide me to get this working.

I can easily stream to rtmp server: ustream and even nginx but can't really
feed ffserver and get

av_interleaved_write_frame(): Unknown error

and have run out of patience trying to get this working. I'll really
appreciate if someone can please help me out with this problem.

Thanks in advanced for your time.

Hi,

My suggestion would be a minimum ffserver config and put all transcode
parameters in ffmpeg with -override_ffserver.
That way it is easier to find out what goes wrong while ffserver keeps
running.

I assume your input stream is ok as you say you stream to other servers.
Otherwise test with 'ffprobe <input stream>'.

Setup ffserver.conf like this:
HTTPPort xxxxx
HTTPBindAddress 0.0.0.0

<Feed channel2.ffm>
File /tmp/channel2.ffm
FileMaxSize 64M
</Feed>

<Stream channel.ts>
Feed channel2.ffm
</Feed>

<Stream status,html>
Format status
</Stream>

Run ffserver in daemon mode and see what is going on on the status page
<serverip:port/status.html>

Then start to feed it with ffmpeg command like

ffmpeg -v debug -i <input stream> -c:v copy -c:a copy -override_ffserver -f
mpegts <ffserver ip:port/channel2.ffm>

You can easily change the transcode settings. I am not sure what you want
to do.
From your previous email I assume your input is RTMP and you want change it
to RTSP. My example has a MPEG-TS output.

This way you isolate what goes wrong. FFserver keeps running and ffmpeg
will give you some clue.

Thanks W Jansen for replying.

I've done what you requested, I would like to do a live stream from my pc
to our network. My PC has a video capture card and would like to send the
feed to a server in our LAN so, others can watch certain videos during a
seminar.

I started with a simple configuration and still can't get it to work.

Here's the output of the command you requested, I'm still lost.

Definitely, I get the same problem with any file even capturing video from
capture card. But, here's the link to the file so you can download it and
test: http://www.figureo56.com/images/david-diaz.mp4

I first tested with files in case that worked I would proceed to live
stream with capture video.

Thanks a lot for taking time to help me out on this. I really appreciate it.
