[FFmpeg-user] Create thumbnails from RTMP stream

Tue Apr 26 19:49:28 CEST 2016

I've simplified the command to try and get one thing working at a time.

Also, I've got it to a place where I can input the rtmp url into vlc
player, and it'll play the video I'm streaming. This rtmp url is the same
input source that the server command uses, but with `localhost` replaced
with the domain.

Local command (works)

ffmpeg -re -i testVideo.mp4 -r 29.97 -ar 44100 -c:v libx264 -f flv
rtmp://xxxxx:1935/osc-simple-ingest/cumin/mp4:cumin_1000

Server command (produces unreadable file)

/usr/bin/ffmpeg -report -i
"rtmp://localhost:1935/osc-live-packager/cumin?offsetFromLive=10,userID=testUser1/mp4:rebroadcast_testUser1"
-y -r 29.97 -threads 4 -c:v copy -c:a copy ./cumin_1000.mp4
