    Since dxva is not working in combination with a postprocessing filter such as DirectVobSub (vsfilter), would it be possible for mediaportal to handle this without a external filter the same way as mediaplayer classic does?



    Since hardware accelleration seems to work with live tv + teletext subtitles, my guess is that this could be done?!

    I'm courious to this also... And a bit supprises that this doesn't come up more. I cannot play a DXVA accelerated MKV within the native mediaportal player.. Even if I choose to not use subs.

    So.. Good idea I think..

    The underlying problem is that MP yet doesn't have parser for .srt text subs or internal support for .sub/.idx subtitles so for MKVs MP just loads Haali-splitter that will internall load VSFilter.dll(DirectVobSub).

    We would need volunteers to code support for those subtitles. The problem doesn't exist on DVD/MyTV side as there we have our own renderer for subs.

    At best this will be post 1.0-version feature and it will require that some MP developer add it as Feature Request in Mantis-bug tracker or we find volunteer developer that will submit code for inclusion.

    Fixed for me.

    Steps:

    1. Install k-lite codepack
    2. k-lite codepack menu -> configuration -> haali media splitter -> enable autoload vsfilter

    Now I can see .mkv files with embbebed subtitles on media portal

    Please don't install k-lite. If you must install codec pack install the least destructive. That being CCCP.

    Or just install Haali-splitter+VSFilter/VobSub and follow FAQ:

    You don't get it. We are not talking about DIVX but About DVXA, we mean Hardware accelerated H.264 acceleration. The problem is when there is another renderer linked to the video decoding, the hardware is disabled. That's why we are asking for an internal subtitles engine, without any external filter, like in Media Player Classic HC.

    Me too. This is for me the best new goal for Media Portal.
    MP use a custom version of evr . I saw it in a filtergraph and evr with 3
    entry pin. With Ati new graphis cards (these one)

    Radeon HD 3800 Series
    Radeon HD 3600 Series
    Radeon HD 3400 Series
    Radeon HD 2600 Series
    Radeon HD 2400 Series
    Radeon HD 3200 IGP / AMD 780G Chipset
    Mobility Radeon HD 3600 Series
    Mobility Radeon HD 3400 Series
    Mobility Radeon HD 2600 Series
    Mobility Radeon HD 2400 Series
    Mobility Radeon HD 2300 Series

    Uvd in supported so hw gpu upscaling support, enhanded imaging ecc.
    h264/avc1 is absolutly fantastic better imho than ffdshow classic decoding.
    so could be very interesting a subtitle engine embedded in MP . Using the
    free MPC video decoder the dxva or dxva2 support should be fully. Also for
    Mpeg-2 and dvd too.

    thanks a lot.
