Why does Mosaic with VLC 2.0.x stop after 9 seconds?

[slimjim]

I am trying to create a 2x2 mosaic with VLC 2.0.3 on W7 x64 using this code:

mosaic.conf

Code: Select all

new channel1 broadcast enabled setup channel1 input "f:\video\test1.mp4" setup channel1 output #duplicate{dst=mosaic-bridge{id=1,height=576,width=720},select=video,dst=bridge-out{id=1},select=audio} new channel2 broadcast enabled setup channel2 input "f:\video\test2.mp4" setup channel2 output #duplicate{dst=mosaic-bridge{id=2,height=576,width=720},select=video} new channel3 broadcast enabled setup channel3 input "f:\video\test3.mp4" setup channel3 output #duplicate{dst=mosaic-bridge{id=3,height=576,width=720},select=video} new channel4 broadcast enabled setup channel4 input "f:\video\test4.mp4" setup channel4 output #duplicate{dst=mosaic-bridge{id=4,height=576,width=720},select=video} new background broadcast enabled setup background input file:///background1440x1152.png setup background output #transcode{vcodec=h264,vb=0,scale=0,sfilter=mosaic}:bridge-in{offset=100}:duplicate{dst=file{dst=f:\video\test.mp4},dst=rtp{sdp=rtsp://:5544/rtsp}} control background play control channel1 play control channel2 play control channel3 play control channel4 play

mosaic.bat

Code: Select all

"vlc.exe" "--vlm-conf=./mosaic.conf" "--mosaic-width=1440" "--mosaic-height=1152" "--mosaic-keep-picture" "--mosaic-rows=2" "--mosaic-cols=2" "--mosaic-position=1" "--mosaic-order=1,2,3,4" "--ttl=12" "--udp-caching=800" --file-logging

The stream and the file both work for pretty exactly 9 seconds, then VLC crashes. The log file says

Code: Select all

main error: url still registered: /rtsp/trackID=1 stream_out_mosaic_bridge error: image conversion failed

I tried this with different inputs (RTSP streams, files) and on different hardware, the symptoms are the same.
With VLC 1.1.11 (code adapted for the versions < 2), the mosaic will not stop, but I get audio issues there ...

Any help or hints to helpful documentation is gladly appreciated.

this occurs because background is a picture and picture playing stops after 9 seconds. Try this option on background in config file and it will be fixed

setup background option image-duration=-1

also you have to set vb (video bitrate) a valid value for example 10000.
your scale also must be a valid value such as 1 or 2 , 1.5 and so on. This value specifies the resolution of output image as scaling factor to statndard resolution 640*480.
