737-29894: Radeon HD 2xxx AGP Series - High CPU usage or system crash during HD playback

The information in this article applies to the following configuration(s):

* PowerDVD, ZoomPlayer
* Catalyst Display Driver 7.9
* Radeon™ HD2900 series
* Radeon™ HD2600 series
* Radeon™ HD2400 series
* Windows Vista 32-bit Edition
* Windows Vista 64-bit Edition
* Windows XP Professional
* Windows XP Home Edition
* Windows XP Media Center Edition
* Windows XP Professional x64 Edition

Symptoms:
On AGP versions of the above mentioned graphics cards the Hardware Acceleration does not get enabled. High CPU usage, stuttering HD playback or even system crash are expected behaviours, although DXVA (DirectX Video Acceleration) is enabled by the application.

Solution:
The root cause of the problem has been identified and a resolution will be available soon. The Catalyst 7.12 is the anticipated driver version to resolve this issue.

Je zaujimave, ze sa jedna o karty HD2xxx AGP, pre ktore sa dorabaju ovladace... ale pre radu X1950 AGP by uz ovladace mali byt odladene, ci nie? ved to muselo v nejakej starej verzii catalystov fungovat! co som pozeral recenzie na webe, tak tam mali dxva funkcne... grrr... myslim, ze to bola verzia 7.6. soudruzi museli nekde udelat chybu...

ATi UVD již podporuje hardwarové přehrávání .mkv

Na tohle čekalo docela dost lidí

návod:

1. ujistěte se, že máte UVD Radeon (tj. jakýkoli HD krom HD2900) s nainstalovanými aktuálními ovladači
2. stahněte si Media Player Classic "Home Cinema" (MPC-HC): http://mpc-hc.sourceforge.net/
3. spusťte MPC-HC
4. View -> Options -> Playback/Output: ujistěte se, že je pro DirectShow Video vybráno EVR (Vista / .Net3)
5. View -> Options -> Internal Filters: Enable all
6. můžete přehrávat

Pokud je v MPC-HC položka EVR (Vista / .Net3) zašedlá a nelze ji označit, nainstalujte si Microsoft .net Framework 3.0 (pokud možno včetně service-packu)

Jak poznáte, že to funguje? Vytížení procesoru by mělo být pod 10% (samozřejmě záleží na konkrétním videu, ale pro 720p by tomu tak mělo být) a pokud si stejné video spustíte v Microsoftím Windows Media Playeru, mělo by být vytížení CPU výrazně (několikrát vyšší).

dík no-xi za upozornění, včera a dnes dopoledne jsem se v tom trochu vrtal, výsledek je zde:
Zprovoznění hardwarového dekódování x264.mkv videa!

Zaujima ma ovsem o kolko % klesne zataz pri pozerani 1080 videa ?
EDIT: Odpoviem si sam, rovnake

Treba doplnit cez treba skopirovat subor MPCVideoDec.ax do system32 a zaregistrovat ho.
Ovsem u mna na HD3870 so vsetkym ako ma byt nefici DXVA

[Mymak]

Toz jsem dnes taky zkusil tu novou ficuru (jinak normalne pouzivam KMPlayer), a k memu udivu kleslo nejen vytizeni CPU, ale i vytizeni GPU. Test na HIS HD3850, 720p i 1080p.

PS: Visty Ultimate & Catalysty 8.5 s CCC

AMD Responds ATI AVIVO Video Converter Feedback



Q: What are the specific issues users of ATI Video Converter may encounter?
A: Users running 32-bit software on 64-bit systems are encountering issues getting quality output from the encoder and 32-bit users have also experienced some anomalies in the playback. It was not released for support on 64-bit operating systems. Our engineering teams have been alerted of the 32-bit issues and are currently working to address them. We have a defined roadmap for the application and plan to add new baseline functionality, ease-of-use and stability in coming versions.

Q: Why are reviewers seeing so little GPU processing during transcoding?
A: The ATI Video Converter uses the GPU for only a portion of the video encoding. Specifically, the GPU currently offloads only the motion estimation portion of the encoding pipeline which is the most compute intensive part of the encoder. The GPU is particularly well-suited for this task. Given that a fixed workload is being offloaded to the GPU the load on the GPU may be relatively low or high based on the specific model of GPU.

Q: When will the stability and quality of the ATI Video Converter improve in a new release?
A: We have a defined roadmap for the application and plan to add new baseline functionality, ease-of-use and stability in coming versions. We are evaluating now when we can most quickly offer those improvements, and will update you as soon as we have more information.

Q: Why did AMD release such a buggy software application into the market?
A: The ATI Video Converter is a basic utility that introduces users of Catalyst to the capabilities of Stream processing on 32-bit operating systems. While it isn’t perfect, The level of functionality and quality is appropriate for maximizing the conversion speed on the most widely used video formats. Improvements are already being made and users can expect to have a much higher quality experience with future revisions.

Q: Why does ATI Video Converter not work on 64-bit operating systems when so many PCs are moving in that direction?
A: While the move to 64-bit is well underway, 32-bit OS’s satisfy the mainstream consumer and the ATI Video Converter was to fill that segment first. We are evaluating our roadmap for future improvements, including the possibility of offering a 64-bit solution.
