Hi,


Thank you for this plugin, it seems to work OK.

Recently I am playing some blueray backups (changed container from M2TS to TS), and it seems they have some different resolutions like 1920x816.
It seems that the DM800 simply stretches it to 1920x1080 and that is not good.

1) Is it possible to set the DM800's output resolution to something custom like 1920x816 ? Or can it only handle the regular formats like 1920x1080 ?

2) If the output resolution cannot be something like 1920x816 then the DM800 needs to add black bars to it and change res to 1920x1080.
(It must not stretch it as it is doing now.)


Thank you anyways,

H2Deetoo

Hi all,

Just start the script below from init.d and run it in the background.
Output resolution will change according to the resolution of the stream being watched. Feel free to modify it to suit your needs. Should work with any image (even old ones)!!

Enjoy!

thanks, das plugin ist super !
habe es jetzt seit einiger zeit am testen und läuft bisher ohne
probleme. auch die umschaltzeiten von sd->hd von box und tv sind auf
meinem plasma recht erträglich...

achja, das plugin läuft bei mir auch nach ausschalten > stromlos > neustart
ohne es neu zu aktivieren.. habs ein paar mal getestet.

hi
thank's for this nice and usefull plugin
my TV have a "cinema mode" to see 4/3 in full screen without image deformation, this mode work only in 480 or 576 , if i use 720 or 1080 TV is automatic in full screen 16/9 mode
so i have do a modification at the original script to use this function

while [ 1 ]
do
aspect=`cat /proc/stb/vmpeg/0/aspect`
res=`cat /proc/stb/vmpeg/0/yres`

case $aspect in
3)
case $res in

echo 1080i > /proc/stb/video/videomode

echo 720p > /proc/stb/video/videomode
;;

echo 720p > /proc/stb/video/videomode
;;

2)
echo 576p > /proc/stb/video/videomode

i put all time my TV on "cinema mode" , when it's 4/3 576 picture i see in full screen without pan&scan or deformation , when it's 16/9 576 picture , TV is switched in resolution 720 so Tv is automatic in full 16/9 screen , and sure if 720 or 1080 , natural resoltion is used
like this all time i have picture without deformation or bad pan&scan and without black border

it will be nice to add this trick, in the python plugin,

@nightmann
sure
problem is only aspect ratio in 576 ,
if aspect ratio = 16/9 in 576 forcing a TV in 720 or 1080 like this TV is in 16/9 mode and picture aspect is ok without change aspect ratio on remote control's TV
if aspect ratio = 4/3 in 576 , use 576 like this TV set is on default aspect ratio ( for mine TV set is nammed "cinema mode") and picture is ok full screen without deformation or bad & scan (on video mode on eningma setup i use just scale option for 4/3 picture) .

I have the same wish as equeorto2.

On my Philips LCD, I prefer watching 4:3 programs in [14:9] mode (the top and bottom of the picture are slightly cropped, but the left and right black bars are thinner, the picture is not distorted and the screen surface is better used).
Unfortunately, in [14:9] mode, the Philips considers 16:9 programs as if they were 4:3 and squashes the picture horizontally. In [auto] mode, 16:9 programs are correctly displayed, but 4:3 programs are then streched horizontally. This means that I must manually change the TV mode according to the program aspect to get the image I want.
In 720p mode, the [14:9] mode is not available, so 16:9 programs are displayed correctly, but 4:3 programs have wide left and black bars.

As the Philips remembers the scaling mode independently for each reolution mode, the ideal situation would be :
- 576i 4:3 programs use 576i and [14:9] mode -> OK
- 576i 16:9 programms use 720p and [auto] mode -> OK

For test purposes, I have patched the autoresolution plugin so that it behaves as stated above.
The patched plugin works OK for me.
The only drawback is that the 576i -> 720p conversion impacts the image quality (deinterlacing + scaling by the DreamBox) - so it is a tradeoff between having to manually change the TV settings or suffering a non optimal picture.

If somebody is interested, I can publish my changes.

yes i'm very intersted Marder , thank's to post your change , i use yet the simple script i have posted before , work fine but sure it will be better a real plugin
thank's

Ok, here it is.

As it is experimental, there is no install package.
You have to install it by :
- unziping the 4 files in the archive
- copying them to the /usr/lib/enigma2/python/Plugins/SystemPlugins/AutoResolution directory, overwriting the existing files (it might be wise to backup them first).
- restarting Enigma2

In the AutoResolution setup menu, there will be a new resolution named "576iw", with "w" as "wide" or 16:9. You can assign it a different mode than the plain "576i".
The 576iw mode will be used when the program is broadcasted in 576i and the aspect ratio is 16:9. The plain 576i mode will be used for 576i 4:3 programs.

This has been compiled for and tested on a DM8000 with the latest CVS. It should work on a DM800 too, but I cannot guarantee it.

Enjoy.

M.

thank's a lot

work perfect here
