[FFmpeg-user] re-streaming rtsp on arm

[ryan lindsay]

Hi
I am trying to take an rtsp stream and send it to ffserver, and have that
transcode it to webm
I have got the version 1.2 from the website and compiled from scratch on my
beagleboard
and it's running ubuntu 12
When I run ffmpeg I get
root at arm:~/ffmpeg-1.2# ffmpeg -i rtsp://
192.168.1.45:8557/PSIA/Streaming/channels/2?videoCodecType=H.264 -f alsa
-ac 2 -i hw:0 http://localhost:8090/feed1.ffmffmpeg version

Segmentation fault

I'm a little confused why it segfaults, and also wondering what the
Seems stream 0 codec frame rate differs from container frame rate: 60.00

refers to
I have set the frame rate to 30 in the ffserver con-fig, because I know the
frame rate coming from the camera is 30fps
Is the segfault related??
