The below script is just some info about how I have created this file.



#!/bin/bash

cat noSignal.ppm \
| ppmtoy4m -F 25:1 -A 4:3 -I p -r -S 420_mpeg2 -v 2 -n 2 \
| cat >noSignal.y4m

cat noSignal.y4m \
| mpeg2enc -f 8 -a 2 -q 1 -n p -T 120 -o noSignal.m2v

tcmplex -i noSignal.m2v -p noSignal.m2a -o noSignal.mpg -m d -d 2

cp -a noSignal.mpg /space/win

rm frame_???.??

/soft/src/x/a.out < noSignal.mpg

cat *.c0 *.e0 > noSignal.pes



I've started with a 720x576 pixel image in ppm format. Attached you'll 
find a short piece of silence and the source of a.out.

I hope you get it working ...

BTW: be aware that noSignal.pes should be no larger than 64 kB. 
Otherwise vdr-xine will only play the first 64 kB which will result in 
bad behaviour.

This file serves for two needs:
A) xine needs a short initial stream to show the OSD (e. g. when VDR is 
in remote learning mode)
B) It is used to get xine into a proper state before the next channel's 
stream starts.

But the later succeeds only for 99% of typical usage. It's likely that 
B) get's dropped once I'll find a better / correct way in xine.

Bye.
