Got FFplayout working, but can't seem to get my ffmpeg argument quite right..

I have ffmpeg compiled good and can play out the Decklink SDI 4k board fine, using this file and line:

ffmpeg -i /home/matt/VideoTests/720ts_6DK01H_tru720og.ts -pix_fmt yuv420p -f decklink -vcodec v210 "DeckLink SDI 4K"

The same file is streaming fine out ffplayout rtmp and can be viewed in VLC with:

In ffplayout there are 2 fields I need to get right, ffmpeg_param and stream_output..
Currently trying:


-c:v mpeg2video -g 1 -b:v 58982.4k -maxrate 9000k -bufsize 18000k -pix_fmt yuv420p -c:a s302m -strict -2 -ar 48000 -ac 2 -f mpegts


-flags +global_header -f flv rtmp://localhost/live/stream -pix_fmt yuv420p -vcodec v210 -f decklink "DeckLink SDI 4K"

The defaults are:

-c:v libx264 -crf 23 -x264-params keyint=50:min-keyint=25:scenecut=-1 -maxrate 1300k -bufsize 2600k -preset medium -profile:v Main -level 3.1 -c:a aac -ar 44100 -b:a 128k

-flags +global_header -f flv rtmp://localhost/live/stream

If you have not tried ffplayout, it is pretty awesome..

Apologies in advance, I know it's not a 100% ffmpeg question but hoping maybe someone will have some ideas..  Thanks!!

Subject: Anyone using FFplayout?

I have it installed from the Docker set up but cannot get anything to play from the playlist/ gui.  Is there any sort or forum or anything on setting it up?  Not much info on the Git page.  Thanks!
