when I play test.ts from a client do I need 'fed' the feed to
ffserver by an instance of ffmpeg simultaneously or can i fed the feed
now and play the file temp.ts later.
I have tried this exercise. sometimes the client plays the file
test.ts,sometimes it does not.
One more question I want to ask is suppose I started feeding the feed
now and I start the client some time later.will the client be able to
play the file test.ts from start?
If I fed the feed to ffserver by an instance of ffmpeg muliple times
and try to play test.ts from client I start getting following errors:
Following is the command line output:
# ffserver -f /etc/ffserver.conf &
