[FFmpeg-user] Error and understanding issue: using ffmpeg to real time publish FLV file to Red5 and real time download FLV from Red5

[Kajari Ghosh Dastidar]

There is an in-built demo in Red5 called oflaDemo, where a client can
record an FLV file from the server. I have tried it and it works fine. I
know there are other standard apps also, which does FLV with Red5.
