Is it true or there are still some problems? In this article we are going to compare performance and playback quality of various video formats, starting from MPEG2 to the latest H.264/AVC. But capacities of the latest video cards for hardware acceleration of decoding H.264 indicate theoretical solution to the problem of playing such files. For example, not all low-end chips have sufficient capacities for the highest resolutions, the level of hardware support depends on a card model and its GPU. There are some limitations for various chips. According to ATI and NVIDIA, their latest video chips help processors decode the most resource-intensive H.264 format in addition to already popular WMV and MPEG2, including high resolutions.

And now even some state-of-the-art CPUs cannot always meet requirements for decoding such a modern format as H.264 in high resolutions, for example in 1080p (progressive 1920x1080). Computers could play DVD only relying on hardware support of video cards. But when DVD Video just appeared, typical processors did not cope well with decoding MPEG2. There are currently no performance problems with playing low-res MPEG2 video (up to DVD 480p/480i resolution). We'll examine it in this article as well.

Not long ago, this year in spring, there was released a high-quality software decoder of the H.264 format, called CoreAVC. For the last two years there appeared DXVA H.264 decoders, CyberLink being one of the first. At first there appeared DXVA decoders for hardware MPEG2 acceleration, then there was released an addon to WMP10 that supported DXVA for decoding WMV9 format. You will need special decoders (ATI DVD Decoder, PureVideo Decoder, CyberLink MPEG2 and H.264 video decoder) and players that support DXVA, such as Windows Media Player 10. Video decoding features of the latest GPUs from ATI and NVIDIA support the following formats: MPEG2, WMV9, and H.264. It allows to use a video processor in decoding and post processing video (deinterlacing, noise reduction, etc). The technology that uses GPU features for video playback is called DirectX Video Acceleration (DXVA). Modern GPUs from ATI and NVIDIA incorporate programmable units to accelerate decoding and post processing of various video formats. The main load falls on a CPU, but modern video cards take up part of decoding and post processing calculations. Playing HD Video (HD stands for High Definition) in modern compression formats, which have high requirements to system resources, is a resource-intensive task even for powerful computers. So we decided to analyze the situation with hardware accelerated video decompression and playback. Either ATI and NVIDIA fine tuned their support for video decoding, mentioned in our theoretical article, or they just grew tired of this task. And now everything seems to settle down a bit. So it was difficult to compare GPU performance, as the situation would change every month.

It had to do with the fact that both ATI and NVIDIA were developing support for video decoding in drivers so actively, that nearly each release introduced lots of new features.

But we had no time to test hardware accelerated video playback.
