Do any open source monitoring/multiview solutions exist?

[cang...@gmail.com]

I’m looking one solution for MPEG-TS/ T2-MI multiviewer (open source)

[Andrew Crawford]

I'm guessing opening several instances of VLC, one for each video on a large computer monitor/TV is a bit too messy? :)

i think this command line should work : 

ffmpeg -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -filter_complex "nullsrc=size=1920x1080 [base]; [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; [tmp3][lowerright] overlay=shortest=1:x=960:y=540" -c:v libx264 -preset ultrafast -f mpegts udp://224.0.1.15:5000

or handle this on a raspberry with omxplayer : 

omxplayer --win "0 0 960 540" -o hdmi --layer 5 udp://@:5007 --live

omxplayer --win "960 0 1920 540" -o hdmi --layer 6 udp://@224.0.1.16:5000 --live

omxplayer --win "0 540 960 1080" -o hdmi --layer 7 udp://@224.0.1.15:5000 --live

omxplayer --win "960 540 1920 1080" -o hdmi --layer 8 udp://@224.0.1.15:5000 --live

I have a working mosaic system working based on ffmpeg libs. Just need to fix audio for the vumeters to work.

Interesting. Keep us updated :)

I tried long time ago using something like the proposed "ffmpeg -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -i udp://224.0.1.14:5000?fifo_size=100000 -filter_complex "nullsrc=size=1920x1080 [base]; [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; [tmp3][lowerright] overlay=shortest=1:x=960:y=540" -c:v libx264 -preset ultrafast -f mpegts udp://224.0.1.15:5000"

But unfortunately even if only one of the streams goes down all the mosaic will freeze.

In addition to that, if one or more streams are not present when you start ffmpeg, it will take ages to start monitoring the streams present and, in any case, will not pick up the missing streams when they start again.

I went mad to find a solution, without success :(

Hi Joo,
I'm really in this. Need a Mosaic TV for monitoring..
