[ffserver-user] streaming from file

[cozzn]

Hi all,








thanks for all help,
Philippe.

I'm looking for a way to stream a file which is being transcoded. ffserver seems suited for the job but I'm having difficulties to configure it correct. My questions are: 1) How do I configure the server so the stream starts at the beginning of the file being encoded? Using the preroll maybe? But how do I set it to the beginning of the file? How do I determine this value? 2) No packets are sent although it seems from the vlc output that the RTSP connection is setup correctly. What can be the problem here? Maybe I immediately jump to the end of the feed so nothing can be send.

ffserver_test.conf
Description: Binary data

This is my setup:

start a server:
./ffserver -d -f ffserver_test.conf
(config file is attached)

start an encoder:
./ffmpeg -i /data/samples/berlitz_junior.mp4  http://localhost:8090/feed1.ffm


start a player (vlc):
rtsp://10.211.55.3:5454/test1-rtsp.mp4


This is output server (when starting the encoder and then the player):
