[FFmpeg-user] Cannot stream live in FLV format. SWF works. Why?

[Roger Pack]

> I would like to generate a live videostream using ffmpeg/ffserver under linux. The stream originates from a sequence of images which are rendered in realtime by processing several sensor data. The images are written as jpegs to the named pipe "jpgpipe" (created by mkfifo) at a rate of 5 fps by a separate process. My problem is that I don't know which is the best format for live streaming with as little latency as possible?

You'd think that with straight images there wouldn't be much latency,
though I'm not sure how ffserver deals with latency.
My previous thoughts on it I wrote up here:
