Scaling & audio issues with 1.0.0

[garyfritz]

I just installed VLC 1.0.0. While it seems to work fine for many things, I have hit two issues:

• The scaler seems to be terrible. I played a 720x480 clip ripped from a DVD, scaled to fullscreen on my 1680x1050 screen. The image was very blocky with lots of artifacts, as if it was just stretched with no scaling/smoothing. Windows Media Player and Media Player Classic both scaled much better. Even at native resolution it showed artifacts, and WMP/MPC looked much better. I could not find any settings that affected this. Am I missing something?
• I tried playing a WMV generated by a screen-capture program, probably Camtasia or something similar. VLC did not play any audio for these clips, while WMP and MPC did. Unfortunately the clips are internal material belonging to a client and I can't post them, but the Media Information says the audio is in stream 0, codec: wmas, channels: 1, sample rate: 22050Hz, bits per sample: 16, bitrate: 20 kb/s. The statistics show decoded/displayed rates for video, but all zeroes for audio.

All settings are at defaults right after a clean install. I'm running on Vista Home Premium SP1.

Any suggestions?
Thanks,
Gary

You need dmo to playback wmas files.

[garyfritz]

I see. OK, am I likely to encounter wmas frequently? I.e. should I just use MPC to play these particular clips and assume I won't see wmas very often? Or is it worth it to go install DMO? (Presumably at http://support.microsoft.com/kb/324290 ?)

Thanks!
Gary

[Jean-Baptiste Kempf]

wmas are quite rare.

[garyfritz]

Cool. Then I will not install the driver. Thanks!

Any suggestions for the scaling issues?

Does it help if you change video output module and/or disable overlay?
http://wiki.videolan.org/WindowsFAQ-1.0 ... _output.3F

[garyfritz]

Nope, I don't see any significant difference.

Here's a pic that illustrates the difference. I grabbed a piece of a scene (an eyeball of an animated character) scaled to full-screen on my 1680x1050 monitor. WMP scales it pretty nicely -- I'm pretty sure the edge effects are part of the image, not edge enhancement -- but VLC looks terrible. Help?

And you tried WinGDI, OpenGL and DirectX outputs? (save and restart after changes)

[garyfritz]

No, because the FAQ page said to use DirectX3D for Vista.

OK, I tried them. OpenGL was better but not as good as WMP's native mode. WinGDI and DirectX were no better than the default settings.

I really don't care if OpenGL disables Aero, but why does VLC have to disable Aero to get worse results than WMP gets in its normal mode?

[VLC_help]

VLC doesn't disable Aero. DirectX or GDI API does that automatically. I might have fix for Direct3D output quality, but because I don't have this issue, I cannot test it.

[garyfritz]

Wonder why you don't get it? Are you running Vista?

I'd be willing to help you test a fix if you want to try running it in my environment.

[VLC_help]

Vista32. I can provide test builds later if you want to test it out.

Slight bump I suppose.. using version 1.0 I had this issue too. Changed video output to directx, restarted vlc, looked good, so i changed back to standard and now it looks good and doesnt shut aero off.. weird.

same problem on Win7 x64 RC1

and same problem in cristal player, i found how to fix it
in Video Renderer menu i change "nearest resample" to "bilinear resample"

may be this option available in vlc?

[VLC_help]

may be this option available in vlc?

Nope. VLC doesn't use DirectShow. Starting VLC in XP compatibility mode should also fix the issue.

Nope. VLC doesn't use DirectShow. Starting VLC in XP compatibility mode should also fix the issue.

no, it does not help. i run VLC with XP SP3 compartible mode.

i just playing with zoom player. it allow to change render
without pixelization works:
haali video renderer.
experimental VMR9 renderless
and EVR

can you add EVR render?

[VLC_help]

Nope. EVR requires use of DirectShow playback chain.

Just registered to say this fixed it for me. When can we expect to see it incorporated into the proper versions?

[VLC_help]

RC is already done.
