[laskos]

Εχω χ1950 προ και οποτε παιζω μεσω hardware acceleration ενα hd αρχειο με οποιον player υποστιριζει hardware acceleration στο κατω μερος του video bgainei mia gri γραμμη. Exv dokimasei polloyw drivers gia thn vga και πολλους Players αλλα συμβαινει παντα. Μεσω software decoding το προβλημα δεν εμφανιζετε ομως το pc δεν εχει την δυναμη να σηκωσει το video και ετσι hardware acceleration ειναι μονοδρομος. Εχει κανεις αλλος αυτο το προβλημα?

Δεν έχει καμία σχέση η κάρτα.

Εχει να κάνει με το encoding των Μpeg-2 αρχείων.

 

Η λύση από το abhdtv.net:

 

One of the more commonly asked questions is why there is a thin white band across the bottom of the picture with 1080 pictures?

 

This occurs regardless of its aspect ratio and is a direct result of using mpeg2 encoding. MPEG needs to be encoded at resolutions that are multiples of 16.

 

Therefore the only resolution where you get the 8 pixels bar is 1080i/p. 480' date=' 576, 720, 1280, 1440 and 1920 are multiples of 16, whereas 1080 is not. Therefore video has to be encoded to 1920x1088, giving you that infamous line.

 

A properly implemented decoder should not display the line, but most manufacturers seem to not care about that too much. After all, most displays used to hide that bar in their overscan area.

 

On CRT PJs, as well as on many new digital PJ's and flat panel displays, you will however see the line and have to find a solution that allows you to get rid of it.

 

On a CRT PJ you can usually use blanking.

 

Software players that reliably hide the line are Theatertek 2 and WinDVD6 - that is without adjustments as you would have to do in ZP.

 

Zoomplayer allows you to use its blanking function to blank the bottom 8 pixels (hit "K" to access the controls for that).

 

Lastly, there is also a tool called FIX1088.exe that can supposedly fix this. However, it can sometimes mess up the stream so use it at your own peril.

 

 

Update 13 Oct 2005:

 

goose posted the following instructions:

 

It is possible to use the crop filter and the deinterlace filter at the same time in VLC

 

make a shortcut to the exe and change the properties thus:

C:\Program Files\VideoLAN\VLC\vlc.exe" vlc --filter=crop:deinterlace --crop-geometry=1920x1072 --deinterlace-mode=blend

 

its exactly the same for bob etc:

"C:\Program Files\VideoLAN\VLC\vlc.exe" vlc --filter=crop:deinterlace --crop-geometry=1920x1072 --deinterlace-mode=bob

 

Just make different shortcuts for the different options

after i started using purevideo, the thin line etc just got away!

THIS WORKS ALSO FOR ATI TO FOR PUREVIDEO IS USING DirectX!
