Decent Hap video playback solution for vvvv [GPU video decoding]

Hi everyone!
The Hap player is up and running! We worked a lot on stability, fixing all the memory leaks (including GPU ones) and crashes. However we’re still in closed beta testing and some functionality is missing (audio output and precise external clock synchronization to mention)

Anyone wants to join our betatesting? If yes, drop me a line to, or to skype: leavittx. I think we need 2-3 people more right now. Especially interested in someone who’ll be doing some VJ stuff with dynamic videos list change!

It is a bit less modular compared to what @elliotwoods proposed, but I find it modular enough


Will the plugin aoutput audio to the VAudio engine?

@sunep yes!

Latest news everybody. Several people have already made really good testing of the plugin. With the awesome feedback they’ve provided over last few weeks, I’ve decided to start public beta-testing today!

Here you go (fresh 64-bit vvvv and dx11 pack are needed, VAudio for audio output)
Known issues are listed in the readme file!


Wow…native HAP …Thanks Lev.

Quickly encoded some of my clips and boom…4 sd videos off my hdd.

.!..might even come out of VJ retirement
because of this…

Need an ssd in my x64 machine now…

Not tried the Vaudio part yet.

A new version of Hap player is ready!

What’s new:

  1. Experimental support of non-multiple of 2 video resolutions
  2. Accurate computation of the current frame index
  3. The image queue size was increased to 10 frames/100Mb, which gives slightly better performance in some cases
  4. Don’t seek to the first frame when the playback is finished
  5. Loop pin of HapAudioClock now accepts a boolean (on/off)
  6. Fix Opened/Playing outputs of HapState: don’t reset to false when opening a single video from the input Path spread
  7. HapReaderNode: make number of ouput slices equal to maximum slicecount of (Path, Open) input spreads
  8. You can open one video multiple times, or open a video using arbitrary Open slice, without opening all the slices prior to it in the Open spread
  9. Now works with vvvv 45beta34.2

Downloads: x64 version, x86 version


niiiice! great news! if you deal with hap there’s a high chance you do that on a 64 bit CPU. so I wouldn’t bother with x86

@microdee i’d like to politely disagree. I have to use a plugin only available in 32bit, but I would have to run hapvid as a sub routine and share the texture, which, given its unreliabilty, isn’t an option for me,

So yes Lev, a 32bit plugin would be appreciated if it isn’t too much trouble.

I’ve just noticed that actually there were 3 more important changes in this version! Please take a look at the updated “What’s new” section of my previous post. Also attached a link to the 32-bit plugin version for those who need it!

Please note that for 32-bit applications there exists a per-process memory limit of 2Gb (by default), so don’t try to preload to memory large Hap files, as it might crash vvvv. So 64-bit is much better choice here.

Will work on better help-patches and post them soon!
