white line

[Moreje 16]

Hello,

I've noticed a white dotted line, just at the limit between image and lower black band, for some of my 4K movies, when playing on my Android 4K OLED TV.

This does not occurs when playing the same movies on my computer.

Any ideas if it is an android app bug or not?

thank you

Hi.  Can we please look at specifics of an example?  You may just need to adjust the overscan on that monitor.

thank you for your response,

I've just sent a debug log using the app option (20:10 French time)

I don't know what you mean by adjust overscan. it is not a monitor, but a Philips OLED TV (model 55POS9002).

Hi.  There should have been an ffmpeg log on your server that went with that as well. 

Most TVs have some sort of "zoom" or size adjustment on them to account for overscan at the very images of the video content.

this is the ffmpeg log:

I've also checked any zoom/overscan setting in my TV, but the is no option like this

If you turn off the option in the app to convert the audio to Dolby Digital, do you still see this artifact?

[Moreje 16]

yes, still present (but no sound anymore)!

if I choose an external player (kodi), this artifact desappears...

Okay, so that means it is not related to ffmpeg and the stream copy.

My guess there would be that the player is actually cropping the video slightly to avoid it but hard to be sure.

You are running the app on the TV itself, not a separate box?
