meglio players come winDVD e PowerDVD o Media Players?

Premettendo che attivo la DXVA meglio players come winDVD e PowerDVD o Media Players?

Media Players ha più possibilità di intervento:

Utilizza renderer del mixer video
Utilizza sovrapposizioni
Utilizza modalità alta qualità

Renderer video precedente
Utilizza inversione YUV
Utilizza inversioni RGB
Utilizza superfici primarie

Mentre sugli altri players il renderer non viene menzionato in alcun menù; come si fa quindi a capire in che modalità sta funzionando l’accelerazione video?

Inoltre le voci sopra menzionate cosa significano e cosa comportano all’atto pratico?

Mi accontento anche di una risposta sintetica. :rolleyes:

Non utilizzo nessuno dei players citati, quindi non posso dirti nulla in merito.

Utilizza renderer del mixer video = VMR (Video Mixing Renderer) 7 o 9
Utilizza sovrapposizioni = Overlay
Utilizza modalità alta qualità = Non conosco il player

Renderer video precedente
Utilizza inversione YUV = conversione spazio colore
Utilizza inversioni RGB = conversione spazio colore
Utilizza superfici primarie = ?

Un saluto. Leo!

Lo scopo dei player alternativi a WMP e' proprio quello di semplificarti la vita.
Sono gia' preimpostati per fornirti la miglior qualita' , questo in teoria.

Per WMP il manuale lo trovi qui':

I concetti di cui si parla non sono immediati , come vedi sotto:

Advanced video acceleration settings
You can use the Video Acceleration Settings dialog box to customize Digital Video (DV) resolution, video acceleration settings, and DVD video settings. The default settings are appropriate for most users. You should only modify these settings if you fully understand the capabilities of your video hardware.
The following options are displayed in the Video Acceleration Settings dialog box.
Digital video option Description
Digital video Specifies the resolution for playback of digital video. Resolution settings include four default options: 88x60, 180x120, 360x240, and 720x480.

Video acceleration option Description
Use video mixing renderer
Enables advanced video rendering capabilities. This option determines which video renderer to use. If you select this option, Video Mixing Renderer-7 (VMR7) is used. If you clear this option, the legacy video renderer is used.

Use overlays
Enables the graphics/video display card to display and scale video from an alternate source on top of the image displayed on the monitor. If you select this option and overlay hardware is available, video is displayed using the overlay hardware of the video card.

Use high quality mode
Specifies use of VMR7 in YUV mixing mode. This mode improves color accuracy, deinterlacing, and scaling on newer graphics/video display cards.

Legacy video renderer - Use YUV flipping
Specifies the use of YUV surface formats when using the overlay. If you clear this option, YUV surface formats for overlay is turned off.

Legacy video renderer - Use RGB flipping
Specifies the use of RGB surface formats when using the overlay. If you clear this option, RGB surface formats for overlay is turned off.

Legacy video renderer - Use primary surfaces
Specifies the use of primary surfaces. If you clear this option, primary surfaces for video overlay is turned off and the Windows Graphical Device Interface (GDI) is used for video display.

Drop frames to keep AV in sync
Synchronizes the audio and video components when the video component lags behind the audio component of a file as the file is rendered to the monitor. Poor synchronization of video and audio components is common in systems with slower CPUs. If you select this option, a large number of video frames may be dropped to maintain synchronization of audio and video in a file.

Enable full-screen mode switch
This option may change the resolution of the monitor when viewing videos in full-screen mode. This option is principally used for older graphics/video cards. Screen resolution returns to its original setting when leaving full-screen mode.

Display full-screen controls
If you select this option, the full-screen controls are displayed on top of the video currently being played.

Use video smoothing
If you select this option, low frame rate files (<15 frames per second) may be interpolated to create a less choppy and a smoother-viewing file.

Video border color - change
Allows you to select the border color for the video.

DVD video option Description
Use video mixing renderer
Enables advanced video rendering capabilities. This option determines which video renderer to use. If you select this option, Video Mixing Renderer-7 (VMR7) is used. If you clear this option, the legacy video renderer is used.

Use overlays
Enables the graphics/video display card to display and scale video from an alternate source on top of the image displayed on the monitor. If you select this option and overlay hardware is available, video is displayed using the overlay hardware of the video card.

Enable full-screen mode switch
This option may change the resolution of the monitor when viewing videos in full-screen mode. This option is principally used for older graphics/video cards. Screen resolution returns to its original setting when video viewing is complete.

Display full-screen controls
If you select this option, the full-screen controls are displayed on top of the video currently being played.

Optimize performance for batteries
In low battery situations, the DVD playback uses a viewing method that requires less power. This option is not available if the power supply is a line supply. If you select this option, the less power-consumptive option is used, DVD frame capture may be unavailable, and DVD video image may degrade.

Preferred decoder - Hardware
Decoders decode audio, subpictures, and MPEG-2 format for DVD playback. Hardware decoders may be built into your computer. They perform well with CPUs of less than 500 MHz because they require less CPU usage. If you select this option, your computer's hardware decoder is used. If the designated hardware decoder is not available, the software decoder is used.

Preferred decoder -
Software Decoders decode audio, subpictures, and MPEG-2 format for DVD playback. If a software decoder is installed, it is the default decoder unless otherwise specified.
