[vdr] Re: Image viewers

[Onno Kreuzinger <onnok@web.de>]

Hi,

as of march 2003 i have a script which uses the dvd drivers stillimage tool, 
the mjpeg tools and netpbm-tools. It works using the mplayer-plugin 
"interface" (a script gets called, the dvb device gets released to be used 
from the script, the script does all the mana).

BUT:
it's dirty, only bash scripting, uses irexec and shell IPC to control the 
slideshow.
more drawbacks:
it needs a patch for mplayer-plugin and i dropped active support due to work 
load (all further work is soley done because i need it for my personal 
uses); most development docs are either english or german.

Advantage:
higher quality, fast, no ffmpeg, works w/o vdr, is documented (engl.), 
everybody can extend it [but no one did ...] and the next version will get 
rid of the last dependecy on ImageMagick (identify for pixes sizes)


for the intressted, older versions are found here (pls. DO use 0.2.6! 0.2.7+ 
is broken) a new update (0.2.8) will come next weekend, my tester will 
report in at that time.

the image handling is based on the old image plugin [convert.sh], but 
decoding, conversation, re-encoding, aspect handling and some navigation 
stuff is re-done. as said the dvb drivers test_stillimage is used, vdr 
should use the same code, but i did not test [but wrote a scritp to get my 
digicam pictures to my vdr and have them pre-converted].


Regards Onno
