Question

I push rtsp stream with ffmpeg，and then I would convert rtsp stream to rtmp stream internally, does it surpport?

ffmpeg -re -stream_loop -1 -i ./video/bigbuck.ts -vcodec copy -codec copy -rtsp_transport tcp -f rtsp rtsp://localhost:8554/222

##Description
According the doc, my config is as follows:
runOnPublish: ffmpeg -f rtsp -rtsp_transport tcp -i rtsp://localhost:8554/222 -f flv -an rtmp://localhost:1935/live/111

The erros are as follows:

Hello, conversion is automatic, there's no need to add ffmpeg...
You can publish a stream with RTSP and pull it with RTMP.

Could you give an example about the configuration? Thanks a lot. @aler9

The configuration is the default one.

Just publish your video to a path of your choice, with RTSP, to the server

ffmpeg -re -stream_loop -1 -i ./video/bigbuck.ts -vcodec copy -codec copy -rtsp_transport tcp -f rtsp rtsp://localhost:8554/mypath

and pull it with RTMP from the server

ffmpeg -re -i rtmp://localhost:1935/mypath ...
