Max 7 64bit Windows - High Performace Video Playback through DirectShow


    Feb 08 2015 | 11:28 am
    Hi there,
    I read in the "Max 7 64 bit Issues and Limitations" found here:
    that jit.movie uses DirectShow for playing videos and that we should install codecs for that as described on the Ableton page here:
    There is a link to the CoreAVC codec, which claims to move the decoding onto supported graphics cards:
    Now I wonder if this remains true for the use in Max? Can we use output_texture for that? Are other DirectShow codes like the HAP Codec supported as well?
    This would be very awesome, since the only way on Windows to get high performance HD playback at the moment is to use the jit.gl.hap (thank you Rob), which only exists as 32 bit external. Since it interrupts playback when reading files, it is necessary to preload all the videos, what leads to RAM shortage quickly...
    If this is not possible, consider this a feature request. For me it's the only thing missing, before jitter becomes the greatest live video software there is. oh, and easier multi-threading support ;)
    To all the Cyclists: Keep up the great work!
    Any comments are much appreciated.

      I just found out, that the jit.movie @output_texture attribute is not working on Windows 64bit :( But I'd still like to know, if there would be a benefit of using a codec like coreavc, that claims to do the decompression on the graphics card.
      I had no luck downloading the free codec from the Ableton homepage, since one of the links is down...

      hi django. yes, output_texture is not supported on win-64 for the time being.
      i just checked, and both necessary links on the ableton page are working (the Haali Media Splitter and the ffdshow). that is what you should install to support mp4 playback with win-64 jit.movie. the coreavc codec is probably useful as well. i'd be interested to hear if the directshow hap-codec works with win-64 jit.movie, but i haven't tried it.
      good luck.

      for windows 64 video support, you should check out the viddll-beta package, available via the Max 7.1 package manager.
