[SOLVED] Easy Movie Texture + 3DCeption (2 Big Ears) sound clicks

If you use H.264 or 265, the video will be decoded in hardware. You can also attach Unity's profiler to see what's consuming CPU. Clicking sounds are sometimes due to audio buffer underruns - what kind of filtering are you doing with TBE? Does the issue repro with the Oculus spatializer?

Video is HEVC (H.265), stereo, 2048x2048. I checked with profiler and there are spikes happening on CPU around the times the sound gets glitchy. Most of CPU time is spent on VR.WaitForGPU during these glithces. This takes anywhere from 14ms to 24ms. If I understand that correctly, this is the time CPU waits for GPU to update?

I made a clean project with the same video and audio and results are pretty much the same. 

I'm using Unity 5.4.0p3, Oculus Utilities 1.8.0 and TB Audio Engine 0.9.9. with Easy Movie Texture.
Video and Sound (tbe format) are loaded from SD card. I'm using Galaxy S6, Android 6.0.1.

Is there a way to play tbe file format using Oculus spatializer?

> If I understand that correctly, this is the time CPU waits for GPU to update? 

Yes. Can you send the output of adb logcat? That will include the time spent on GPU.

> Is there a way to play tbe file format using Oculus spatializer?

Not directly. You would have to target Unity's built-in audio system and then set the spatializer plugin to Oculus in the project's audio settings.

Okay, here is the logcat output from clean project.

This is almost double the recommended number of polygons, which can lead to stalls and dropped frames. Given the low numer of draw calls, my guess is you're drawing a finely-tessellated sphere. Any chance you can use a cubemap projection or lower-res sphere?

Yeah I used the default spheres from Easy Movie Texture and forgot to move each sphere to it's own layer, so they were both renderer twice per each eye. Sorry for that.

I replaced the spheres with the one I'm using in my real project (1224 polygons) and result is the same. I disabled the video and sound is still glitchy. I have a scene where a guy bangs on gongs and this is where it gets the worst. 

I am using default Unity audio settings, same for TBE.

In Audio Settings, can you try setting DSP buffer size to "Default"? There is a known issue if you use "Best Latency".

Hi, I tried with all available options under Audio Settings > DPS buffer size. I tried to disable Default Unity audio and this results in much better sound, no clicking until it reaches the part with gongs. The sound in this part "vibrates" and echoes and it's quite loud.

I am starting to suspect that something is wrong with the tbe file itself. Default one that comes with TBE plugin works great.

Hey tomazvovk!

The official support group for the Spatial Workstation and the SDK is here: https://www.facebook.com/groups/1812020965695437/

Would you be able to follow through there? The issue you are facing is likely caused by distortion on the device. Turning the mix down before export or changing the volume of the TBSpatDecoder object should help.

I tried lowering the volume from 1 to 0.5 and then to 0.1. No change. I joined the Facebook group, waiting for confirmation.

Thanks!
