Stream videa - ffmpeg

[Ondrej Koala Vacha]

DObry den,

jako druhy server po Helios jsem zkousel ffmpeg 
http://ffmpeg.sourceforge.net.


# ffserver -f fconf.conf 
ffserver started.
127.0.0.1 - - [Wed Feb 16 10:17:33 2005] "GET /ld2004.ffm HTTP/1.0" 200 8245
127.0.0.1 - - [Wed Feb 16 10:18:29 2005] "GET /stat.html HTTP/1.1" 200 1863

Prvni problem byl, ze s dodanym ffmpeg.conf se to nechtelo rozjet, z mne 
neznameho duvodu tam musi byt pritomna sekce pro avi stream.


# ./ffmpeg -vd /dev/video0 http://localhost:8090/ld2004.ffm

Pokus o cteni ld2004.avi vsak skonci padem ffserver-u :(


Nemate prosim nekde stream videa do netu rozbehany nebo vite o nejakem 
hezkem HOWTO? Netrvam ani na Helix ani ffmpeg.
