Hap Direct Show windows problems

Fred

@DusX no I just play the file and it flickers. Using a flip actor doing nothing in between fixes it. I saw something like this when I had incorrectly set double buffering on open gl....

@Fred
Interesting. Thanks

@Fred @DusX

I have no software that will allow me to compress HAP on Windows. I suspect this problem shows up for high resolution clips, and I can't make one. Is there a way to get a short (10 sec) high resolution clip that might allow me to reproduce this issue?

In the meantime, it seems that adding a GPU actor after the output solves the problem, right? I would use that as a workaround until I can offer you a real solution. (Perhaps it's a good idea to put this GPU actor inside a user actor; then you can then edit the User Actor to remove the GPU actor later to get rid of the extra copy.)

Best Wishes,

There are also, many test files at: PathToIzzyCloud\ISADORA\QAandSupport\Media

Thanks Fred. Very helpful. I have added these to our test file base.

@mark Keeping the flip in is my solution for the moment, but with flip I get around 70 cycles and without I get 200, so for this project at this stage it is OK (I am just planning and designing), but I have a month to get it going and am a bit nervous about these glitches getting solved in time.

Fred

@DusX Out of curiosity, did you try these files? Do you also get the flickering?

If you can get me 10 seconds of test file I'll solve it before you're show. Send me an email about this and we'll figure out a way.

P.S. I've also downloaded the open source compressor created by Render Heads. I want to figure out why a normal HAP movie is twice as big on PC as on the Mac.

I have tried with 2.5.2 and it plays the file ok, when I launch isadora after installing, this is with the preferences set to 30 fps. Once I bring the framerate up and the srervice tasks to 4 then the flashing comes back. Using an inactive flip actor still solves this.

Dear Fred,

We were too close to the release to fix this for v2.5.2, as it might have introduced show-stopping bugs. It is now at the top of our priority list.

Best Wishes,
