Hey Lord-Grey it started in alpha 10. The debug logs are at the start of this thread but let me know if you need anything else.
As long as I'm able to manipulate the export JSON to set a width and height of 64 at least I'm able to "fix" it, but if I can't do that it'll be unusable.
Just feeding back here that I still get stuttering of video with these settings on 2.0.14.
Stuttering:
Not Stuttering:
So if I manually change the width and height to 64 in the JSON export before re-importing it, the stutter goes away. It appears that both width and height must be the same value to avoid the stutter which is why having width and height available to edit would be useful for me at least, perhaps as an advanced option.
I'm seeing very slight flickering of WS2801 LEDs on the Rainbow Swirl effect for example whereas usually I'm unable to notice the transition of colours. It doesn't happen all the time. This is with 2.0.14 on Pi 2. Not sure if this was a result of upgrading from 2.0.13, but if I get time I can try to revert to that version to test. Having the grabber enabled or not doesn't make any difference to it.
Thanks Lord-Grey but as I wrote before, 30 causes the lags in video playback. So something is different setting both width and height to 64 and decimation value of 8 vs 1920x1080 decimation value of 30.
I ran in to this issue again today after updating Hyperion and realised that the width and height values in the export were set to 1920x1080. I manually changed the export file to width 64 and height 64, reimported and fixed the issue. Could this be available to edit in the web UI?
Maybe you share the url you are using?
https://github.com/hyperion-pr…e/effects/matrix.json#L14
I suspect that effect file needs to be fixed to use a different URL, since that URL resolves to a HTML page containing an mp4 for me in Chrome. Gifer output changes depending on accept header. I've submitted a PR.
Hi
On latest 2.0.12 release installed on OSMC, the "Matrix" effect doesn't appear to work. The image in the effect URL resolves to an animated gif, so the image exists. Any pointers?

Is there any way I can force a width and height of 64, regardless of source dimension? I.e.
https://discourse.osmc.tv/t/vi…yperion-is-running/9577/8
EDIT: Manually changed the export JSON file, setting width and height to 64 and pixelDecimation to 8 and reimported. No more stuttering issues. Not sure why or how this could be done in the Web UI but at least I can run the latest version without issue.
Hyperion 2.0.0-alpha.9 works fine on a Pi 2. I upgraded to that from the old Hyperion.
Unfortunately, the alpha versions after 9 don't work so well and cause video stutter.
EDIT: I Just managed to get the latest version working smoothly by tweaking the config manually.
Unfortunately alpha 11 still causes video lag when the grabber is enabled. I tried decimation values between 20-30 and less frequent capture rates but this did not fix it. It does seem better than the last build, but alpha 9 with width 64, height 64 and frequency of 10 works perfectly.
Testing this on alpha 11
Should I open a GitHub issue or do you have everything you need here?
Tried frequency of 10 and decimation values of 20 and 30 but juddery video/dropped frames persisted. This with 1080p content. Video lags away from audio drastically until the grabber is turned off.
I tried decimation at 30 and a few other values, but I honestly cannot remember which combinations of frequency. I can try 10Hz and 20 decimation. Is that right? I'm confused about how that relates to the working value of 64x64.
Thanks for your help!
Incidentally, I came up with 64x64 for the frame grabber on alpha 9 because of a couple of threads I found like this one where it says it has to be a power of 2 and the same width/height to work: https://discourse.osmc.tv/t/vi…yperion-is-running/9577/7
Not sure if it's possible or necessary to achieve the same on alpha 10, although I didn't get the same HDMI disconnections with alpha 10.
Will providing the respective config JSON files suffice, as I'm on alpha 9 now (working fine) and don't have screenshots of that section in alpha 10.
I reverted to alpha 9 and the stuttering went away. I experienced the HDMI disconnection issues as I did before on that version, but I cured that by setting the framegrabber width and height from 80x45 to 64x64.
I'm not sure where the issue is with alpha 10 but it seems the changes in this area have negatively affected performance.
Another observation on alpha 10 is that on alpha 9 when I cleared the lights (I use an iOS app called Hyperion), they faded off and now they just cut off abruptly.

Would really appreciate some advice because I can't watch anything with v10 installed because the lip sync gets worse and worse until I disable the capture.
Not sure if relevant but only Framebuffer and DispmanX are shown in the drop down. The save button is unavailable if I choose Framebuffer.
Tried with a picture decimation setting of 30 and this makes no difference to the frame loss
On the previous version I used defaults except for the LED config.
grabber-v4l2 has a width and height of -1 and sizeDecimation 8. Are those the values I need to look at? framegrabber has a width and height of 64 and a 10Hz frequency.
