Videos not working? Convert to WebM!

  • 1
  • Announcement
  • Updated 3 years ago
For anyone using our Rise Vision Chrome App Player, you have likely noticed that since upgrading Google Chrome to version 33 or higher, MP4, MOV and FLV videos have stopped playing. We are aware of this issue and are trying to determine the best course of action now.

In the meantime, to get your videos to play, the best option would be to convert them to the WebM video format. WebM's don't rely on Flash to play, and instead use the HTML5 Player to show in your Presentation.

Instructions on how to convert a video to WebM can be found on our Video help page here, and if you have any questions, please let us know.

Thanks!

Hopefully, this is not a permanent solution.

Do we have an ETA as when this issue is going to be resolved?

Maxim,

While we still recommend WebM, I am able to get MP4, MOV, and FLV playing on my Chrome Players.

Can you check to ensure that you are running on version 34 (or higher)?

Thanks.

Ironically, I am currently having issues with WebM format videos... If there are 3+ videos in the playlist, only a certain number of videos (2 specific videos) actually play. It lags out throws up a white box at the top of the screen (like the window is not responding) during the transition (there are no transitional effects) from 1 video to the other. Then it shows 1 frame out of the video for the remainder of the time of the video as a still frame, then goes blank to white and starts eventually playing one of the working videos after the others have elapsed. Its a strange problem and difficult to describe, but only happens when a certain number of videos in the playlist have been reached.

Matthew, off the top of my head, the behaviour you describe sounds as though your hardware might be having problems playing the videos.  Are the videos large in terms of file size?  Can you switch to 3 small videos (there are some samples on the 'net if you search for WebM sample videos) to compare?

Interestingly enough it works better with larger files than short ones. 17mb file [30+ sec] plays fine, while the 1.2mb file(s) [16 seconds] are glitching. I've tried several different configurations to debug the problem but nothing seems to serve any valuable evidence or clear variables in the matter. I was able to workaround the problem by combining the video files into a single video file so that there are only 2 items in the playlist. As soon as a third/fourth item are added it quits playing properly. The videos play fine in preview mode on my computer, but the devices with the Rise Chrome player running Windows 8.1/4gb RAM/100+GB SSDs/Intel Celeron with Integrated Graphics the issue occurs on a device in the field and a local device we used to replicate the original problem (laggy mp4 files)... I converted them to WebM files to improve the quality and performance issues we were encountering with the Google Spreadsheet  Dual Screen with Full Screen Video. Its running a Menu with a full Screen Promo both at 1920x1080 pixel resolutions.

Matthew, are there any other transitions taking place in your Presentation when the third (or fourth) video starts to play?  I did see one instance where somebody had multiple placeholders each with large images that changed every few seconds and they noticed that the video "glitches" coincided with when the images changed in the other placeholders.  What happens if you just test a presentation with the videos in it and nothing else?

If I understand you correctly, the two machines this is happening on are the same hardware, is that correct?  Also, are you using the Video item or the HTML 5 Video widget and where are the videos stored, ie Rise Storage or somewhere else?

Rise Vision Storage

Video Item only...

Same Hardware, & Tested on Similar Hardware
However, the presentation plays fine on that hardware using the Preview mode and only about 30% to 40% CPU even with other applications running simulat

Has no issues with MP4s of the same videos

Matthew, I am not sure what the issue is off the top of my head, and I have not had this experience with playing 3 or more videos.

I think you said above (it wasn't 100% clear) that you tested this with a presentation with only one placeholder with only videos in it using the Video item, correct?  And, have you tested with other videos that you didn't create - ie my suggestion about some of the samples you can find in a Google search?

If you send me a link to the presentation I can put it up on my own test display and let you know if I see the same issue and I will let you know.

Hi Matthew,

I was able to take a copy of the Full Screen Only Videos and put it on my Win7/Chrome Packaged App display and I am not seeing any problems with video playback performance.  It was also tested on a Win8 machine with no issues.  So the issue appears to lie somewhere in your environment, but I can't say where.

As an aside, I am unable to play the other presentation because I don't have a dual display but you did say the issue happens with only the videos so that doesn't seem necessary.

Well the screen that is currently running at the clients location is the one with the spreadsheets. The issue is present in both situations. I simply made one without the spreadsheets to see if that fixed the problem and as a backup for performance reasons in case we needed to isolate them on separate displays to resolve the original MP4 sluggish performance problem. Which led me to convert the files to WebM format. Which led me to this thread with this problem.

When I encountered this issue, I choose to convert MP4, FLV, etc to WebM. I think this way is easier for people who are Newbie just like me.

When it comes to how to how to convert MP4, FLV, MOV, etc to WebM, I couldn't help recommending this step by step guide to you. Works like a charm.

Tried downloading Miro and I get the error that it is a virus site. Please advise and suggest another option.
Thank you.

Michelle,

I have personally only used Miro converter. There are many options online for converting videos to .webm, you might want to take a look at google for some recommendations.

We are encountering problems with MP4 videos glitching or not playing at all.

(i) Is this a problem that you guys continue to see with the Rise Chrome player?

(ii) Are you still working with Google to improve flash/mp4 functionality or would you recommend WebM as a permanent solution to an ongoing issue?

Taylor,
Are you encountering problems with MP4 only, and not WebM?
It is also dependent on the hardware. For example, if you are running the Rise Chrome App Player in ChrOS vs the Chromebit. We haven't really tested on Chromebit. As for ChrOS, we are still currently evaluating Chrome Application development. The latest version can be downloaded at https://chrome.google.com/webstore/de... with the last update being November 2015.
Thanks

Thanks for the prompt reply. We are using the Chromebit and the latest version of ChromeOS. We are encountering problems with MP4. We are testing WebM today.

We converted our videos to WebM.

We have three 15 second videos files playing (as well as static slides). The WebM videos play smoothly (no glitches).

Is Rise Vision working on a solution to improve the way that MP4 files play?

Dependent on your hardware (ie Chromebits). I know of other presentations that have played MP4s but are on different hardware (ie NUCs).
