Intel Graphics Technology GPU accelerated video decoding

Mar 12, 2019

Feem coob GPUs ua txij thaum 1995 txhawb lub YUV qhov chaw xim thiab kho vajtse overlays, tseem ceeb rau cov video playback, thiab ntau GPUs txij li ntawm 2000 kuj txhawb MPEG primitives xws li kev them nqi zog thiab iDCT. Qhov txheej txheem ntawm kho vajtse accelerated video decoding, qhov twg ntawm cov txheej txheem yees duab thev yees duab thiab video tom qab ua haujlwm tau raug tso tawm rau kev kho vajtse GPU, feem ntau hu ua "GPU accelerated video decoding", "GPU pab video decoding", "GPU kho video decoding "los yog" GPU kho vajtse pab suab seev suab ".


Tsis ntev los no cov ntawv teev lus graphics txawm hais txog high-txhais yees duab ntawm daim npav, tshem tawm cov chav ua haujlwm ua haujlwm. APU feem ntau rau GPU ceev suab seev suab yog DxVA rau Microsoft lub operating system thiab VDPAU, VAAPI, XvMC, thiab XvBA rau Linux-raws li thiab UNIX zoo li operating systems. Tag nrho tsuas yog XvMC muaj peev xwm hais tau cov yeeb yaj duab encoded nrog MPEG-1, MPEG-2, MPEG-4 ASP (MPEG-4 Tshooj 2), MPEG-4 AVC (H.264 / DivX 6), VC-1, WMV3 / WMV9 , Xvid / OpenDivX (DivX 4), thiab DivX 5 codecs, thaum XvMC no tsuas muaj peev xwm ntawm decoding MPEG-1 thiab MPEG-2.
