Re: [Red5] Red5 Bad Quality and Time Lag

[Salil jain]

I am posting all the converation again as I see that some comments were missing due to my stupidity...if they are not i hope its ok to post it again

 

We are trying to run a live feed using red5. We have installed red5 on a linux box. Its running fine. But with video and audio feed we are having a lot of lag. And also the video is of pretty bad quality. Are there some parameters in server configuration which we can set to get better quality?
Looking forward for your suggestions eagerly. (also this one)
Thanks
Salil

AFAIK, Red5 does only transport the video from red5 to client or vice
versa. So the quality only depends from the flv file you have at the
server or the webcam / mic  you have at the client, unless red5 drops
frames when required bandwith exceeds porvided bandwith (not implented
yet at version 0.4.x, I think)

Hi,
Thanks a lot for response. Ok here is what we are using. We have one computer which you can say at a place A and it has a camera attached and its connected to publish a live stream on a server at location B and we are checking at a location C (just receiving). Its only one broadcaster and one receiver. Though we have tested following cases and it works fine:
1) broadcaster at C server at C and receiver at C while everything was on different machine on local network (it works ok)

2) broadcaster at C server at C and receiver at C while broadcaster and server are on same machine on local network (it works good ..better than previous case..best among all configurations)
3) broadcaster at A server at A and receiver at C while broadcaster and server are on same machine on local network (it works ok but worse than 1 and 2 case)
 
Geographically A and B are near and C is quite far.
I hope this helps.
Best Regards
and thanks again

Hi,
Can you please explain which bandwidth you are talking about? broadcaster, server or client?
Thanks
Salil

Particularly because it works well when everything is at location C,
then the connection to the outside world must be the weak link.  How
high of quality and bandwidth are you trying to achieve and what kind of
Internet connections do you have at each location?

Hi,
Thanks for your response. I will look into the bandwidth issues now. I would like to know if we use FMS will it

give similar results (which are bad) if bandwidth is an issue. I would guess the answer is yes..but I am not an

expert and seek your answers (thats why i am posting here at)
Thanks again for all your responses.
Best Regards
Salil

it is likely a bandwidth spike issue.
give us info about frame size, fps and setQuality parameters.
