I have an mp4 video on my Dropbox. I was able to watch it earlier with the Dropbox app, but now it asks me whether I want to view it with the Photos app or Video Player... and neither appear to work.

I have tried saving the video to my device but still no luck. I am able to watch the video through VLC player with no issues but I am trying to post the video to Instagram, and Instagram can't understand it either.

I can also view the video on my iPad... and I've tried force stopping my Android apps and restarting my phone but still no luck

    Sounds like some problem with codecs maybe. Did you recived android update near time when videos become unplayable? Do you use custom rom? Feb 27, 2017 at 20:39

I realised the problem was there because the video was 1200 x 1200 — I'd exported it from Photoshop — I then resized to 600 x 600 and then it seemed okay, and could post it to Instagram


Try using VLC, it plays most videos other players cannot and has a good interface. However, if this still doesn't work, try using Video Converter, Compressor and select the file then change it to an MP4 (I know it's already MP4, but this may fix any issues).

VLC: https://play.google.com/store/apps/details?id=org.videolan.vlc&hl=en

Video Converter, Compressor: https://play.google.com/store/apps/details?id=com.xvideostudio.videocompress

  • thanks, I'd tried VLC player as per my post but had also tried the converter / compressor to no avail unfortunately!

  • That's a shame, but I'm glad to see it works now through Photoshop!
