[FFmpeg-user] FFmpeg record RTMP to FLV

[shacky]

Hi.
I'm trying to record some RTMP stream with FFmpeg to a FLV file or
something else.

I'm trying the following command:

ffmpeg -i "rtmp://94.47.147.130:1937/live/livestream" -f flv -t 60 test.flv

But I receive a 6 byte file which seems to contain only one frame.

This is the output of ffmpeg:

ffmpeg -i "rtmp://94.47.147.130:1937/live/livestream" -f flv -t 60 test.flv
