  FFserver ain’t stream

  Posted by Dominik Reider on March 5, 2011 at 4:54 pm

  Hello all!

  Im struggeling here with an issue and i dont get whats wrong.

  First I started FFserver. In another console I typed my ffmpeg command as follows:

  
domdom@ubuntu:~$ sudo ffmpeg -an -f video4linux2 -s 640x480 -pix_fmt yuyv422 -i /dev/video0 -f mpeg -b 64 -s 160x128 https://localhost:8090/feed1.ffm

  As you can see, the command prompt appears directly without any other lines which shows the streaming… And i dont have a stream… Thats what makes me wondering as the same command works if i put a filename instead of the feed. (I used the original ffserver.conf).

  It seems obvious that i missed something, but i dont find anything anywhere in the web…

  Any ideas?? Thanks for help in advance!!

  cheers dominik
