Either use -flags -global_header or -f ssegment

I am using ARM processor (DM8168).
The total memory available is 256 MB.
Also, there are several other processes going on in the system like live
streaming of 4 streams.
In this scenario system does not always have enough memory to support 138 MB
allocation.
Thanks,

I seem to remember reading that Youtube uses (Or at least used to use)

I guess this would be a similar situation.

You may only use FFmpeg if you agree with the

Hi,
Not sure if this is the place to ask but I have a licensing questing

Can I create an encoding workflow that incorporates ffmpeg in the process in
a corporate environment?
The "Encoding Workflow" product that uses ffmpeg would only be used in house

Hello, I have Blackmagic Intensity Pro video card and I want to stream video

Yes FFmpeg can feed static file to ffserver.
Is it possible that FFmpeg will listen multicast data packets from VLC and
simultaneously feed these packets to ffserver?
