How can I out text and time over mosaic screen?

new channel1 broadcast enabled
setup channel1 input v4l:/dev/video0:term=PAL:channel=0:size=400x300:colour=32639
setup channel1 output #duplicate{dst=mosaic-bridge{id=1,height=300,width=400},select=video}

new channel2 broadcast enabled
setup channel2 input v4l:/dev/video1:term=PAL:channel=0:size=400x300:colour=32639
setup channel2 output #duplicate{dst=mosaic-bridge{id=2,height=300,width=400},select=video}

new channel3 broadcast enabled
setup channel3 input v4l:/dev/video2:term=PAL:channel=0:size=400x300:colour=0:palette=0
setup channel3 output #duplicate{dst=mosaic-bridge{id=3,height=300,width=400},select=video}

new background broadcast enabled 
setup background input fake:
setup background output #switcher{files=/X/bin/image.uyvy,sizes=800x600,command=1}:transcode{sfilter=marq:time:mosaic,vcodec=mpgv}:bridge-in{delay=400,id-offset=100}:duplicate{dst=display}

control background play
control channel1 play
control channel2 play
control channel3 play

time and text at "back" of mosaic, like mosaic -> text+time -> background
I don't see text

And can I put out diferent text or time on each frame of mosaic?

How to out picture to display with out comression? I tryed to remove vcodec, but so no picture out

only "late picture skipped"

Sorry for my English..

I tried some mosaic + logo + marq filters together, and it seems that mosaic and the others don't work well together. I've 'solved' it by transcoding the other filters for the second time, but that's a very CPU-consuming solution. A code snippet from my conf file:

Code: Select all

setup background output #transcode{sfilter=mosaic,vcodec=mp2v}:transcode{sfilter=logo:marq,vcodec=mp2v}:bridge-in{delay=400,id-offset=100}:duplicate{dst=std{access=udp,mux=ts,url=localhost:1234}}

(btw, with the latest dev version, you can remove the switcher part and add a --fake-file <background>.png to your command line to get a nice background to render on)

Perhaps someone from the dev can look into why a mosaic subfilter doesn't work properly with the other filters together (using sfilter=mosaic:logo for instance)?

A little bump, I'll clarify my question again.

I tried some mosaic + logo + marq filters together, and it seems that mosaic and the others don't work well together. I've 'solved' it by transcoding the other filters for the second time, but that's a very CPU-consuming solution. A code snippet from my conf file:

I'd like to do this with a single transcode:

Code: Select all

setup background output #transcode{sfilter=mosaic:logo:marq,vcodec=mp2v}:bridge-in{delay=400,id-offset=100}:duplicate{dst=std{access=udp,mux=ts,url=localhost:1234}}

First render the mosaic, then add a logo and a marquee. But the logo and marquee don't appear when the mosaic filter 'goes first'. If i put them like this: logo:marq:mosaic, no mosaic is rendered (also not as you would expect).

Anyone from the dev team know what's up with this behaviour of mosaic?

i've had the same problem. I'll try to have a look at what might be wrong.
