[Live-devel] [live-devel] Too long delay for JPEG live image.

Hello,

I'm trying to developpe a MJPEG live streamer server.
I work with a camera and our specific driver (that I've wrote too) for our
frame grabber.
To do this I've learned about Elphel example.
I've wrote a JPEGVideoSource derivated class then I've overload the
doGetNextFrame function.

Now I can see remotely live JPEG video from camera with a VLC client
program.
But I've observe a delay of 2 sec between images received by the driver and
those received by VLC client.
It seem there is a too big fifo buffer for live image between them.
I've disable our fifo buffer to see what's happened.
Now I copy directly image (30 kB) to FramedSource::fTo data members.
But the problem is always present.

How can I reduce this delay?

Thanks in advance for your help...
