Hi Roger,
I've written a static image watermarking filter using vfilters.
I'm not sure if this would help you.

Hi,
I have an application that uses a FastVDO SmartCapture device to
stream live video to a Wowza server. On the server, it is being
streamed live and also recorded for archive.
I would like to be able to add a watermark image to the video either
before it is sent to the server or as it is being recorded. I have
tried to add a watermark after it has been recorded which was
successful but the process takes too long and is too resource
intensive to do on any sort of scale. I couldn't find a way to just
add the watermark without having to re-transcode the video.
The broadcast client is running in java on a windows netbook. It
communicates with the fastVDO device using jni and receives the raw
video & audio packets which it then packages into an rtp stream to
send to the server. If possible, I would like to be able to pass
the raw video packets through the ffmpeg avfilter, to add the
watermark image, before they are added to the stream if this is
possible.
The other option would be do it on the Wowza server and intercept
the video packets there and do the same thing.
I am also open to other suggestions.
Roger.
