watch videos in portrait orientation?

[zaboron 0]

Hi lately I have been using emby to watch downloaded instagram videos. They're all filmed in portrait orientation and I'd like to play them back that same way. Unfortunately emby always automatically flips to landscape mode during playback, making them super tiny. Can you make this a bit smarter please?

The issue is the original recordings are incorrect - emby is simply reading the media header and doing what it does with all the other media and orientating it correctly.  ie Emby IS being smart 

 

You can edit the header in the source file and trick it to become portrait, but I doubt you'll want to do that for every video you download.

 

ffmpeg.exe" -i landscape.mp4 -map_metadata 0 -metadata:s:v rotate="90" -codec copy portrait.mp4

 

.. will rotate the video 90 degrees without re-encoding it.

are you sure?

here is the media info:

 it seems the media header is correct and emby is being dumb.

hmm ok - perhaps the Android app is ignoring the orientation flag - we need @@ebr to comment here as I only tested the above in a web browser.

 

What is the orientation for standard landscape media use in comparison ?

landscape media is played correctly in landscape orientation

landscape media is played correctly in landscape orientation

 

"Orientation: Top left"

 

Is this the same for landscape media ?

the emby android mobile app simply always uses landscape orientation and tries to fit the video as good as it can into that. of course a portrait oriented video fits much better into a portrait orientation. Unfortunately there is no way to switch between the orientation mode in emby's video playback.

ok - so this is exactly my point.  How do you expect emby to magically know that this particular video is an 'instagram' video and should be played portrait - when it has been 'told' to play landscape ?

 

I can get a video to play in emby web in any orientation I choose using the ffmpeg rotate function - I'm going to try it in the android player to see if it works via that player as I'm now curious ..

I don't want emby to magically know how to play the video, I want myself to be able to tell emby in what orientation to play a video.

This works perfectly well - I just tried it on my android phone .. ?

 

I just added another version of the same file - phone held in portrait.

 

original copy - as expected, emby flips the video to play in landscape, meaning I need to now hold the phone in landscape.

modified version - as expected, emby flips the video to play in landscape, but as it is now already the correct orientation, I do not need to hold the phone in landscape.

 

Yes, this is a workaround but it works.

 

Maybe suggest this as an option in the suggestion thread - possibly a 'per library' option but it would only work for transcoded (ffmpeg'd) streams I think.
