Re: [rtmpd:6207] Live Stream from ffmpeg to crtmp doesn't streaming live (and also laggs)

[C++ RTMP Server]

Hi,

That is because ffmpeg/avconv may have packets dropouts. Remember, -f rtsp assumes UDP for transport. Search how to force RTP over TCP and I'm sure it will give superior results.

An alternative, would be:

ffmpeg …… -f flv -metadata streamName=test1 tcp://localhost:6666

Best regards,
Andrei

With vlc or (on Android) via VideoView I can watch the stream. First of all my crtmp-config and the ffmpeg-instruction:

The video also has many failures (perhaps in en/decoding the video). The most bad part is, that a change of the input.jpg (on the machine, which runs ffmpeg) needs more than 10 seconds to take effect on the stream in vlc-player.
