iPhone and iPad - black/blank video playback

Hi there,
I use Apple devices.
Recently the video playback starts in black/blank screen. Only controls appear, the video itself doesn’t.
I have to switch to PiP and back.
My affected devices are

  • iPhone SE (3rd), previously it was good, I use it for 2 years.
  • iPad 9 (I use it since december, black screen issue exists since first usage)
    iOS and iPadOS versions are latest.

Another user had the sort of same issue Playing video recording from library on iOS app show black screen

Thank you for your help.

  • I didn’t change anything for several months.
  • Just bought a new iPad.
  • I have 2 Hikvision x265 cam, and 1 old mjpeg EasyN


  • I logged in webclient as recommended (with my iPad’s browser)

  • I watched one of x265 videos from the library in webclient: OK (iPad)

  • I watched that video in NCS application on my iPad: OK

  • I watched one video from mjpeg camera in NCS application on my iPad: BLANK

  • I watched the good video in my iPhone application: OK

  • I watched the bad video in my iPhone application: BLANK

  • I watched the bad video in webclient on my iPad
    … and voila everything is good everywhere.

But. It is working now.
Thank you

The playback on my iPad is black again :frowning:
update: and on my iphone too

I have the same problem. iPhone 15pro, iPhone 14 and an older iPad. Live video works fine on all, black screen when playing recording in the app. All work on web.

Any new on this?

I have an update. The problem seems to be that the played image is behind… the background in the app. When minimizing the app while playback that shows black screen the image appears.
This may suggest that the app needs an update.

I have this problem occurring now also. Black video playback. Can someone please look into the app and rectify this?

thank you

Sorry, but no feedback from developer yet. Suggest using the web client.

Thanks Henrik. That’s not really a good alternative as it’s quite clunky to use the browser on the phone for this purpose. That’s why there is an app that should really be maintained and not a “build and forget” attitude. There is obviously some issues with the app under the newer ios and it would be responsible for the developer to maintain the status of the app.

Has anyone found a fix…I have sam eproblem!

I am having problems with only iphones viewing the mjpeg stream from NCS just recently…not sure if this is related.
The stream just flickers real fast.

Could you just recompile or what, just update the client?
I see in the Store that the latest version has been issued 2 years ago, meanwhile there was a lot of OS upgrade (and new SDK too, I think).
A year ago we could use it without any issue, but since last fall we can’t watch recordings on our devices.
I don’t think webclient is a good alternative solution, especially on small phone devices.

Hi All. So I was the other user Henrik mentioned in the first post. The work around that I found works for me; when you open the app on iOS and you click through to ‘library’ and ‘list’, if I just clicked a recording it would bring up a blank screen, so instead, hold your finger on the video until it slightly pops and becomes a few pixels bigger. Once you have done this, click any video you like and it plays as normal.

Obviously your mileage may vary, but for me this works all the time.

Is it slightly annoying, yes, but at least I can see the videos without having to use the pop out video to watch them.

Hope this helps people.

Unforunately it doesn’t work with my iPhone SE 3rd, iOS 17.5 and iPad 9th, iPadOS 17.5
(on iPad it was good for one try, but never again)
@Henrik , please, can we expect any update?
