Image widget slideshow crashing displays ... ?

  • Not a Problem
As Picasa is finally gone, and Google Photos won't work for us, last week we uploaded all of the images from our Picasa albums into RV storage. Then we used the image widget to show the full screen contents of this new 'slideshow' folder full screen in our presentation.

But soon after we started getting reports of our Chromeboxes crashing, 4-5 each morning, which then had to be manually rebooted. But it's happening more often and to more units, 6-8 at a time the past few mornings now.

This image widget slideshow, pulling from RV Storage, is about 45 images, totaling about 30 MBs. Is there a limit to the images that the player or the image widget itself can play without having problems?

Or would the problem lie elsewhere ... (eg. file name length)?

Thanks,
Robert

rcruse,

How 'heavy' each image is? RV does not support Chrome anymore. From my Chromeboxes I can tell that sometimes they have issues uploading even smallest images. IMO your best bet would be keeping those images as 'light' as possible. I would use 72-96 dpi JPGs, reduce the size to 720p and apply 60-80% quality compression. The difference should not be all that noticeable on a regular TV display.

The images weigh anywhere from ~300K to 1.2 M. I've also considered breaking the slideshow into two parts to help the load on the player. Would doing that help?

Robert,

I think Darius may be on to something; you may want to check the pictures to see how large they are, and scale them to fit the Placeholder they are in. Another thing I would strongly suggest is converting them to the file format WebP to see if that helps the situation.

You can break down them down to individual images, but there is always the possibility you could run into this issue with the same images. I would try converting to WebP first and see how you make out.

Let us know what happens!

We have a new lead it seems ....

The presentation just before the slideshow is just a 15 second PSA-like video. It's ran in it's own presentation with a MP4 video for months now. But it's now crashed my test box several times lately. Sometimes it just seems to hang when loading the video, then just skips it in the playlist. The next time I may get the sad face screen and the unit reboots.

So I converted the MP4s video to WebM format, just to make sure it's not a video format issue. And it still is not loading and/or crashing the unit.

So I've removed any videos that use the Video widget and are served from RV storage. This is actually the second time we've had to remove a video playing from RV storage using the video widget. But we thought it might have been the size of the video. But this current video it only 15 seconds long, and less than 10 MB.

We've also been experiencing some a second or two of black, then a hiccup, before videos want to begin playing ....

Any ideas to get video playing once again? Is the video widget having issues?

Thanks,
Robert

Robert,

Any chance you could email support@risevision.com a link to your Presentation? I'd like to take a look at the Videos to see if I can recreate the same thing you are seeing. We are going to be releasing an update version of our Rise Cache in the coming weeks that should help with the black flash issue, but i'd like to see what is going on that is causing this issue.

Thanks!

I'll send you the two video presentations I've removed from our playlists.

I've run them on the test signage TV in my office, the past couple of days. I've found that if they don't skip, stutter with playback, or shut down the unit ... after they've run a few times  I often receive a white screen and this error: "There is a problem playing that video. It could be that we don't support that format, or it is not encoded correctly."

This is odd, as we've played these little 15 second video presentations for 6 months or so. And they've only recently started having problems. So to make sure I hadn't just been lucky all this time playing MP4s, I also went ahead and replaced them with WebM versions (which are the preview versions above). But I still see the same behavior.

So ... Is there a memory/cache/buffer limit for the size or number of images in a slideshow using the image widget? Is there one for the video widget?

Thanks,
Robert

Darius,

When they are submitted to me, these videos are about 15 MBs each. So I've pared them down to 10 MBs or a bit less. But even if that's large for a 15 second video, 10 MBs itself is not very large for a single file nowadays. I've played videos that were over 1 GB in video presentations previously with no problems.

Thanks for your feedback,
Robert

Interesting. Thanks for sharing those Robert.

I'll get you an answer as soon as I can if I can recreate them or not.

Thanks!

Robert,

Just wanted to let you know that I am running copies of these Presentations (Wellness Tip 1 and 2) and both run fantastically for me. I will leave them up for as long as I can and let you know if I see anything out of the ordinary, like that message you were seeing.

Thanks!

I thought I had solved the problem by removing the two video presentations. But that was a red herring. Only after a few days, the issues have become worse.

Since I can't know the display status of each Chromebox/TV unit, i have the media techs from each of the campuses walk around and view our signage TVs each morning and email me a status report.
(We don't have CDM, even for it's basic status check screenshot.)

Here is a sample of the many reports I've been receiving over the past week from the media techs:

-- "At least three monitors this evening, at various times, were displaying, "this file does not exist or cannot be accessed."  Just thought I'd let you know. "

-- "For some reason the Chromeboxes seem to get stuck saying they can't locate a file. I had to reboot 4 of them today"

-- "I had to reboot 6 Chrome boxes today.
Lately they seem to be getting more and more buggy."

-- "This morning 3  Chromeboxes had to be rebooted.
One of the common issues I've seen is that there is a message that says "file not found or does not exist". Is this something that can be fixed from your end?"

I've actually gotten more "file error messages" than anything else. I don't know why our slideshows, once we moved them from Picasa to RV Storage have become so problematic?

Could it be the size of the images in my slideshow, as another poster suggested?

if so, what is the recommended individual image size or total slideshow folder size that RV players,  Image widgets, or Chromeboxes can run without memory issues, if that is the case?

If not, how would you recommend tracking down a problem that is 'most likely' the slideshow,  but also could be something else unknown?

The only pattern I could find is they often crashed in the morning, and after restart most would begin playing again fine for a while: some the rest of the day, some would again display the file error or would reboot themselves after several minutes of the next 'hangup'.

(I know CBoxes aren't supported anymore, but I've got to support them until they are eventually replaced.)

Thanks much
Robert

Robert,

Very sorry to read about those issues above. We fixed an issue earlier today that was affecting Chromeboxes that you can read about here. Can you try rebooting to see if this solves the issue on those Displays?

If the size of the images is significantly larger than the Placeholder, OR a very large file size, it is possible there may be issues when trying to show it on the Display. I would suggest converting to the WebP format for all your images, which I have had great success with.

Let me know how you make out with the suggestions above!

The images' dimensions were already the exact size of the placeholder.

Yesterday I ran these all of these slideshow images through Photoshop again, reducing the quality of the JPG export to medium. This seemed to half the size of each individual image, thereby reducing the memory required to display the complete slideshow of images itself.
We'll see what happens.

Thanks for you help,
Robert
