gfx bugs in 2.x with mp4 files

[Jean-Baptiste Kempf]

The issue is ONLY with nVidia and DxVA!

Can you file a bugreport, please?

[Larix]

with gpu decoding and nvidia gpu ?

yes

[Jean-Baptiste Kempf]

Drivers version?

[Larix]

295.73. The latest WHQL Driver.

[Schnuffel]

hmmm
i use this driver too (tried older version too)
with gtx 260

with vlc version
vlc-1.3.0-git-20111222-0002-win32
and older it worked

since version
vlc-1.3.0-git-20111222-0628-win32
it is broken

so there must be a change/bug in source code

[Larix]

I have downloaded the vlc 1.3 and I haven't nothing problems.
What video output module do you use?

[Schnuffel]

default
but happens with all modules

which nvida card do u have ?

[Larix]

Nvidia GTX 460

[Schnuffel]

and u are sure to have gpu decoding enabled in vlc
and u have no errors in the bottom of the video ?

[Larix]

No errors in mp4 files or dvds.

[Schnuffel]

okidoki

one last question
u tried the mp4 file i have uploaded ?

[Larix]

yes

[Schnuffel]

oki

hmmm
i force vsync in nvidia driver
to prevent gfx inductor noise during games
i wonder if this could be the problem....

edit: nop thats not the problem


hmmm may be its best to compare source code of
2.0 final with
vlc-1.3.0-git-20111222-0002-win32 (last working version)

and see if there was a change in mp4 decoding and if yes
just replace 2.0 final mp4 code parts with code from vlc-1.3.0-git-20111222-0002-win32

[Jean-Baptiste Kempf]

This means it is a probable change of code from libavcodec that broke it.
Please trac it.

[Schnuffel]

ok done


i 'll create a trac for the cue/flac compression bug and for the visualisation audio stutter bug too


i heard that vlc was 1st designed for linux only
may be it would be better to create a new vlc from scratch for windows....

hmmm or i should try linux and see if vlc runs better with it

[Schnuffel]

bug has been fixed with 2.0.1
