Streaming for a jpg file

Postby Miliow!! » 09 Feb 2007 13:00

Hi to all!!

I'm trying send a stream of jpeg file. I don't know if it's possible.
I have read about it in the forum and I have find something about mjpeg codec. I read in the vlc documentation that mjpeg codec isn't compatible with udp and rs streaming so I use http streaming

I'm trying this command :

Code: Select all

vlc -vvv /home/videolan/stream/foto.jpg :sout='#transcode{vcodec=mjpg,vb=768,scale=1}:duplicate{dst=std{access=http,mux=mjpg,url=0.0.0.0:1234}}'
But this don't work. VLC show me :

Code: Select all

the muxer is mpjpeg, and you should use a live video for the input.

Hello dionoea, thank you for your reply.
I don't understand. Why I should use a live video for the input? Can't I use a jpg file?

Hello dionoea, thank you for your reply.

the jpg format doesn't support streaming because it has low frames per second
using live video is of course better because if its quality :) and speed
maybe there are softwares that support jpg as input, but I'm not aware of them. Any way you can enjoy these sites jemsite.com, thereeftank.com
