Hello:
I need to generate keyframes inside an FLV.
I'm doing a small web app that records the webcam onto a Red5 server.
I need the resulting FLV files on the server to have at least 2
keyframes per second.
I'm using *setMode*, *setQuality* and *setKeyFrameInterval* to attempt
to control the quality and framerate of the uploaded video
When I record within a LAN, everything is fine. I get a lot of keyframes
on my FLV files.
But when I record on the internet (e.g. 128kbps upstream) I get
keyframes every 5 or 6 seconds.
I know I can't challenge physics, so I think there's a way to generate
additional keyframes on the server side FLV.
I don't care if the file size is increased because I'm planning to
download the files via HTTP.
I just need to be able to jump from any "second" to any other second,
and I belive I need 1 keyframe per second to achieve that.
I know Flash Media Server has the "enhanced seek" feature that forces
the server to generate keyframes on demand, so it is possible to "seek"
to any given frame in the video.
Anyway i think this feature only works when playing back a video via rtmp.
So what I actually need is a way to generate keyframes inside an FLV
file that was previously recorded. I can be a process that runs after a
video was recorded.
Any ideas?
Thanks,
JulianG
