hardware decoding
on Jul 13, 2009 at 12:07:03 am

Hello, sorry I'm a little noob with hardware decoding and need some help. Not sure if this is the right place for my question, if it's not I'm sorry and I hope you can lean me to the correct place where I can ask my question. I want to know how to tell if my player is using hardware decoding or software decoding. before I continue here is details of my configuration:

1. Computer: Pentuim 4 2.86Mhz, 512MB Ram, 40MB Disk / 250GB Removable USB
2. Operating System: Windows XP SP3
3. Software used: Media Player Classic Home Cinema 1.2.908.0, VLC 1.0, Windows Media Player 9 ( which comes preloaded with Win XP SP3)
4. Source codec: I have .Mov MPEG4 file
5. Destination codec: N/A
6. Type of destination use: N/A

The video card I have is a little old, it's an ATI Radeon 9800 Pro 256MB.

I heard that VLC does not support hardware decoding, is that true?
not sure about Windows media player, any thoughts? I was adviced to try Classic Media player home cinema because it can do hardware encoding.

my card's specs show the following is supported:
# MPEG-2 decoding with motion compensation, iDCT and color space conversion
# All-format DTV/HDTV decoding
# YPrPb component output*
# Adaptive de-interlacing and frame rate conversion
# Dual integrated display controllers
# Dual integrated 10-bit per channel 400 MHz DACs
# Integrated 165 MHz TMDS transmitter (DVI 1.0 compliant)
# Integrated TV Output support up to 1024x768 resolution

this is acording to this Document

So, since it says all-format DTV/HDTV decoding is supported, does that mean it supports MPEG4 and H264 hardware encoding? sorry if my question is silly, I'm a noob with encoding...

Also I used mediainfo on the .MOV file that I want to check, it says it's an MPEG4 file , does that mean it could be H264 or is that something else? here is an image that shows what mediainfo says:


so how do I tell if my player is actually doing hardware encoding or software encoding? thanks...

Hi, I can't seem to be able to edit my message, I want to appologize for my spelling mistakes, please note a little close to the end of my post I said "so how do I tell if my player is actually doing hardware encoding or software encoding?" what I meant to say was "so how do I tell if my player is actually doing hardware decoding or software decoding?", sorry again for the confusion...

Regards
Akram

Your clip is and H.264 (AVC), MPEG-4 .MOV.

Your graphics card is not performing any hardware accelerated H.264 decoding.

so my clip is h264 MPEG4? how could you tell it's H264? I only see MPEG4 and AVC...

also about my card, it does not support decoding of h264 because it's too old correct? my only option is to install a new card then for hardware decoding , correct?

AVC is H.264

http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

Your card simply does not support h.264, it's not just because it's old.

Have a look at the Radeon HD 2900 series.
