Wokspace Preset Locks on trigger

Support

Hi,
Seeing if anyone else has this issue with VTDecoderXPCService taking really high CPU? I’m getting a really long freeze between triggering workspace presets and I’m making the connection to this high cpu task.

2017 Macbook Pro
Mac OS 10.12.5
Chipset Model: Radeon Pro 560

VDMX licensed version
Version b0.8.7.1.0

More info:

  1. Tried ‘killall’ on VTDecoderXPCService task
  2. Running x 3 layers with Photo JPEG codec
  3. Limited effects in my patch

Two notes…

  • Unrelated, but you may want to update to the latest VDMX
  • VTDecoderXPCService is the process in which the OS does decoding of certain video streams, such as PhotoJPEG. You’ll probably get better performance switching to a more modern codec codec, especially for HD footage. In particular you may want to try HAP.

vdmx: b0.8.7.1.7
macOS: 10.14.6

I post here since is related.
I usually use HAP codec but I don’t remember VDMX not working at all with propres.

Hi,
Yea, it looks like VTDexcoderXPCService is a process that eats a huge amount of CPU when playing back videos. It’s part of the Mac OS and there is no one to disable it from what I could find.

I found @davidlublin 's comment above to fix it. The only way that service doesn’t turn on and use a huge amount of CPU for me is when I convert and run videos as HAP codec (I believe because that utilizes the GPU).

VDMX works fine with ProRes, but it uses up more system resources to playback than HAP. Depends on your use case, quality vs number of total layer / maximum resolution.
