2010-02-03 10:57:48     problem with video streaming (camserv or ffserver)

Hi,

ffmpeg works for me. I can stream a videosignal to a single pc with ffmpeg .... udp:ip_pc:1234

 

But what I need is a streaming server solution.

 

I try camserv, because it works nice for me on a x86 system. On the blackfin (537) I allways get this error:

 

[main] Picture taker could not be created!

 

Next I tried ffserver. But if I start ffmpeg after ffserver I get this error:

 

L1 allocation failed!

 

can't map 'usr/lib/libavcodec.s0.51'

 

I think that ffmpeg and ffserver can not start at the same time.

 

I need a simple streaming server solution for the blackfin. Maybe somebody can help me. Thanks!

Please free more L1 memory from the kernel config and try again.

 

You can also try VLC instead of ffserver.

I did what you say and it seems to help. Now I can start ffmpeg and ffserver together. Unfortunataly I still get no stream. I think there must be a configuration problem...

 

Does anybody know why camserv not work? I think it is a very nice little streaming application.

Unfortunataly I found out that the ffserver.conf file was right. It works on my notebook with this file all right. So it must be special problem on the blackfin, that ffmpeg and ffserver can't run together. Maybe it is a performance problem. I have already free the L1 from eathernet rx/tx packets. Can I do more?
