[SOLVED] Background MOSAIC image (fake://) in VLC 2.0

[mucc]

Hi all,

I use the following VLM code for generate a mosaic without problem since VLC 1.0 :

Code: Select all

del all new monitoring broadcast enabled setup monitoring input udp://@239.0.0.1:3000 setup monitoring option programs=7202,7220,7221,7222 setup monitoring option audio-visual="visual" setup monitoring option effect-list="spectrum" setup monitoring output #duplicate{dst=mosaic-bridge{id=1,height=240,width=240,name="Channel1"}, select="es=192", dst=mosaic-bridge{id=2,height=240,width=240,name="Channel2"}, select="es=160", dst=mosaic-bridge{id=3,height=240,width=240,name="Channel3"}, select="es=176", dst=display,select="es=260"} new mosaic broadcast enabled setup mosaic input fake:// setup mosaic option mosaic-width=960 setup mosaic option mosaic-height=480 setup mosaic option mosaic-yoffset=60 setup mosaic option mosaic-position=1 setup mosaic option mosaic-order="1,2,3" setup mosaic option mosaic-rows=2 setup mosaic option mosaic-cols=2 setup mosaic option fake-file="C:\VLC_monitoring\background.jpg" setup mosaic option fake-caching=50 setup mosaic option fake-width=960 setup mosaic option fake-height=600 setup mosaic option fake-fps="20" setup mosaic option fake-deinterlace setup mosaic output #transcode{deinterlace,sfilter=mosaic,vcodec=mp2v,vb=10000,acodec=none}:bridge-in{id-offset=100}:display control monitoring play control mosaic play

The same script with VLC 2.0 do not work.
I read that the fake module do not work in version 2.0 , it is correct?

How can I generate a mosaic with a background image?

Thanks

yes, fake is gone. Use the image demuxer.

I have modified the preview code with the following:

Code: Select all

del all new monitoring broadcast enabled setup monitoring input udp://@239.0.0.1:3000 setup monitoring option programs=7202,7220,7221,7222 setup monitoring option audio-visual="visual" setup monitoring option effect-list="spectrum" setup monitoring output #duplicate{dst=mosaic-bridge{id=1,height=240,width=240,name="Channel1"}, select="es=192", dst=mosaic-bridge{id=2,height=240,width=240,name="Channel2"}, select="es=160", dst=mosaic-bridge{id=3,height=240,width=240,name="Channel3"}, select="es=176", dst=display,select="es=260"} new mosaic broadcast enabled setup mosaic input "C:\VLC_monitoring\background.jpg" setup mosaic option mosaic-width=960 setup mosaic option mosaic-height=480 setup mosaic option mosaic-yoffset=60 setup mosaic option mosaic-position=1 setup mosaic option mosaic-order="1,2,3" setup mosaic option mosaic-rows=2 setup mosaic option mosaic-cols=2 setup mosaic output #transcode{deinterlace,sfilter=mosaic,vcodec=mp4v,vb=10000,acodec=none}:bridge-in{id-offset=100}:display control monitoring play control mosaic play

But the result is not the same with fake module:

1. The video mosaic is to small.
2. After few seconds the mosaic window closes
3. For transcode mp2v not work. Now I use mp4v

What am I doing wrong?

[Sébastien Escudier]

try the image-duration option

[mucc]

Thanks for the suggestion.

I have added "setup mosaic option image-duration=-1" , now the mosaic do not close!

But I have another problem, the option mosaic-* are not working.
The mosaic is shown as:




The dimension,yoffset, order of flow... are ignored.

What's wrong in my configuration?

Code: Select all

del all new monitoring broadcast enabled setup monitoring input udp://@239.0.0.1:3000 setup monitoring option programs=7202,7220,7221,7222 setup monitoring option audio-visual="visual" setup monitoring option effect-list="spectrum" setup monitoring output #duplicate{dst=mosaic-bridge{id=1,height=240,width=240,name="Channel1"}, select="es=192", dst=mosaic-bridge{id=2,height=240,width=240,name="Channel2"}, select="es=160", dst=mosaic-bridge{id=3,height=240,width=240,name="Channel3"}, select="es=176", dst=display,select="es=260"} new mosaic broadcast enabled setup mosaic input "C:\VLC_monitoring\background.jpg" setup mosaic option mosaic-width=960 setup mosaic option mosaic-height=480 setup mosaic option mosaic-yoffset=60 setup mosaic option mosaic-position=1 setup mosaic option mosaic-order="1,2,3" setup mosaic option mosaic-rows=2 setup mosaic option mosaic-cols=2 setup mosaic option image-duration=-1 setup mosaic output #transcode{width=960,height=480,deinterlace,sfilter=mosaic,vcodec=mp4v,vb=1000,acodec=mp2a,ab=128}:bridge-in{id-offset=100}:display control monitoring play control mosaic play

[Jean-Baptiste Kempf]

-1 means forever.

[mucc]

Yes -1 means forever!
I wanted that result, that's great!

Now the problem is the mosaic options: as you can look in the screenshot posted above, I can not modify mosaic dimension,yoffset, order of channels ....
I think that the problem is in the following part of code:

Code: Select all

new mosaic broadcast enabled setup mosaic input "C:\VLC_monitoring\background.jpg" setup mosaic option mosaic-width=960 setup mosaic option mosaic-height=480 setup mosaic option mosaic-yoffset=60 setup mosaic option mosaic-position=1 setup mosaic option mosaic-order="1,2,3" setup mosaic option mosaic-rows=2 setup mosaic option mosaic-cols=2 setup mosaic option image-duration=-1 setup mosaic output #transcode{width=960,height=480,deinterlace,sfilter=mosaic,vcodec=mp4v,vb=1000,acodec=mp2a,ab=128}:bridge-in{id-offset=100}:display

Why "setup mosaic option mosaic-xxxxx" commands are ignored in VLC 2.0.0?

[Sébastien Escudier]

I don't know why, but you can give the mosaic option at startup with :
--mosaic-height=
etc...

Hello,

I have a similar problem with the new VLC 2.0.0 final release when I use the fake option.
For example, this playlist content code doesn't work anymore :

Code: Select all

#EXTM3U #EXTINF:0,PICT - My Picture #EXTVLCOPT:fake-file-reload=1 fake://http://192.168.1.10/my_picture.jpg

How can I translate this playlist to work with the image demuxer ?

Best regards

[Sébastien Escudier]

remove fake:// and use to image-duration option for how long you want it displayed

[KingKebab]

remove fake:// and use to image-duration option for how long you want it displayed

Thanks Sébastien, you're helpfull
Now I can read image file with VLC 2.0.0 !!

I'll try to transcode my picture to MPEG2 streams, is there something special to know about image demuxer streaming ?

[mucc]

I don't know why, but you can give the mosaic option at startup with :
--mosaic-height=
etc...

Thanks Sebastian! Now work fine!
I had not thought this solution!!

My vlm conf, if it be helpful:

Can you edit the wiki too?

Trying to do much the same thing. We have a mosaic with a background image and a full screen video. When the video stops we see the background image until we get video back again. Under VLC 1.1.11 this worked fine. Now that 'fake' is gone I simply removed that and it won't show the video anymore, only the background image.

Here is what I have for VLC 2.0

Code: Select all

del all # Background new bg broadcast enabled setup bg input "c:\LOS.png" setup bg option image-duration=-1 setup bg option sub-filter=mosaic setup bg output #bridge-in{offset=100}:display # Mosaic setup bg option mosaic-alpha=255 setup bg option mosaic-height=480 setup bg option mosaic-width=704 # setup bg option mosaic-align=5 setup bg option mosaic-xoffset=1 setup bg option mosaic-yoffset=1 setup bg option mosaic-vborder=1 setup bg option mosaic-hborder=1 setup bg option mosaic-position=1 setup bg option mosaic-rows=1 setup bg option mosaic-cols=1 setup bg option mosaic-order=tracking setup bg option mosaic-delay=0 setup bg option mosaic-keep-picture # Tracking Stations new tracking broadcast loop enabled setup tracking input "rtsp://PATH TO LIVE STREAM" setup tracking output #duplicate{dst=mosaic-bridge{id=tracking,width=704,height=480},select=video,dst=bridge-out{id=0},select=audio} # VLM Control control bg play control tracking play

And here is what I have that works under VLC 1.1.11

Code: Select all

del all # Background new bg broadcast enabled setup bg input "fake://" option "fake-file=LOS.png" option "fake-width=704" option "fake-height=480" option "fake-ar=4:3" setup bg option sub-filter=mosaic setup bg output #bridge-in{offset=100}:display # Mosaic setup bg option mosaic-alpha=255 setup bg option mosaic-height=480 setup bg option mosaic-width=704 # setup bg option mosaic-align=5 setup bg option mosaic-xoffset=1 setup bg option mosaic-yoffset=1 setup bg option mosaic-vborder=1 setup bg option mosaic-hborder=1 setup bg option mosaic-position=1 setup bg option mosaic-rows=1 setup bg option mosaic-cols=1 setup bg option mosaic-order=tracking setup bg option mosaic-delay=0 setup bg option mosaic-keep-picture # Tracking Stations new tracking broadcast loop enabled setup tracking input "rtsp://PATH TO LIVE STREAM" setup tracking output #duplicate{dst=mosaic-bridge{id=tracking,width=704,height=480},select=video,dst=bridge-out{id=0},select=audio} # VLM Control control bg play control tracking play

Am I missing something simple here?

[Sébastien Escudier]

mosaic options must be in the command line, the wiki has been updated
