Playback of 4k60 Quicktime files

Having a bit of bother playing back 4k60 files filmed using an iPhone.

The file is currently sat on a windows share, which is mounted in fstab, it starts to play back initially ok (albeit upside down) then starts to stutter, then stops entirely.

I should add that, i have just retired the video and it played ok, from both the windows share and a local usb drive. however still plays upside down, is there anyway to fix the orientation?

3

Quick googleing and i come up with this:

4

I appreciate the link, but i was hoping to avoid anything that resulted in having to re-encode a 4k60 video because i filmed something in a different orientation to what Apple deem as the correct one.

In essence the video plays perfectly on my MacBook, unfortunately my windows PC is currently out of commission, otherwise i would test it there. However, i am well aware of the long-standing issues with iPhone videos/photos and orientation issues.

I should also add that the preview image in Kodi/OSMC shows correct, its only when you play the video that it doesn’t

5

We had a similar topic 1 year ago. But at that time there was a orientation flag set in the file which I can not see to be set in your mediainfo. Without that info I am not sure how Kodi can fix playback.

6

Well i did see this in the media info, is this not the same thing?

Display aspect ratio : 16:9
Rotation : 180°
Frame rate mode : Variable

7

I didn’t see that in your posted info. If that is there than there is some hope.

  1. Can you upload a short part of the video (or record a short new one with the same mistake)
  2. Can you try with hardware acceleration disabled (might not play smoothly but at least could tell if it is upside down)
8

Correct. It will let us know if we’re ignoring something we shouldn’t be ignoring; or whether ffmpeg also fails to detect the proper rotation.

9

Ok, I am not going to upload any part of the original video as it is my children Nativity play, but i can try and recreate the “error” if it is still needed.

However, when i tried to playback the video with hardware acceleration turned off, the video play in the right orientation albeit extremely slowly and choppy as we would naturally predict for a file of this nature without hardware acceleration.

10

Can you record another video which reproduces the problem using the same device of something else, like filming a magazine or paper?

I have filmed a 5 second clip that has the error but its doesn’t play well because of the screen adapting at the start. I can film a longer clip if you want? Also can i send it to you privately as it contains meta-data i don’t want shared on an open forum.

Sure, just send me a private message.
