    Default Codec video HD de la ATI

    Cei ce au o placa video de la ati seria X1000 pot folosi codecul AVIVO impreuna cu DVBdream.
    Eu am un HD 3850 si sunt foarte multumit.
    PROtv hd se vede super in aceasta formula.Calitatea imaginii e mai buna, decat daca folosesc CoreAvc 1.6.5.0..
    Pe lcd-ul calculatorului nu se simte diferenta dintre cele doua codecuri, insa pe plasma de 106 cm se vede.

    Diferenta e data de faptul ca coreavc decomprima software H264(calitate slaba, foloseste la greu procesorul) iar celelalte 2 folosesc decodorul hardware h264 al chipseturilor ati (calitate imagine net superioara, mai ales la imagini dinamice gen sport).

    [email protected] Intr-adevar am observat la fotbal de pe PROtv HD. Se simte diferente dintre codecuri la imagini dinamice.
    Pe procesorul meu Intel CORE DUO, codecul de la ATI utiliza 30 max 40%,iar CoreAvc-ul folosea 70% din procesor.

    Trebuie sa mearga si pe placa ta ati hd2600. Codecul de la ATI nu e vazut de Altdvb. Merge cu Dvbdream ultima versiune.

    De codecul ati nu stiu dar cyberlink stie sa foloseasca decomprimarea hardware, procesorul sta la 4-6%, imagine reala intr-adevar(asta cu altdvb, signal refresh anulat - altfel procesorul creste cam cu 20%).

    Cyberlink este singurul codec cu suport DXVA acceptabil si ofera decodare H264 integrala pe GPU pentru placile cu chipset'uri nVidia G84, G86, G92, G94 si ATi RV610/RV620, RV630/RV635, RV670. Placile ATI ofera in plus si decodare VC1 integrala. Restul de placi decodeaza partial.

    ATENTIE: Toate functiile de decodare hardware merg DOAR cu ajutorul unor filtre DirectShow/Playere care stiu sa le foloseasca (Cyberlink, InterVideo, Media Player Classic Home Cinema).
