Moblin support for portrait mode streaming

[fdebbabi]

The stream via Moblin seems possible only in landscape mode. Any idea how to stream in portrait mode
from within the app?

My hack for now is to send it to a middle component that is going to do a rotate for something that should be native I believe.

This is extremely beneficial for portrait live streams (IRL/Outdoor) that target smartphones so that viewers can see a bigger and sharper image and not simply a 16:9 image in a 9:16 canvas (a big part of the frame is black) (check added photo to see how the stream looks on smartphones screens without doing the hack

)

Settings -> Streams -> My stream -> Portrait not sufficient, and rotate 90 degrees in OBS?

Widgets are not supported in "portrait". They will be rotated 90 degrees.

As I stream outdoor for 1-5 hours, my goal is to skip OBS part (that I am doing currently), my goal is to send stream following the first approach as there is less dependency/requirements/things to manage at home and when things fail when I am outside I don't have to stop livestreaming and go back at home and fix things:

1. Moblin(SRTLA) -> Belabox(SRTLA) <- RTMP Relay -> (Youtube, Tiktok and Instagram simultaneously)

2. Moblin(SRTLA) -> Belabox(SRTLA) <- OBS On my PC to rotate -> RTMP Relay -> (Youtube, Tiktok and Instagram simultaneously)

I see. No one is working on adding real portrait right now, so likely not supported anytime soon

[fdebbabi]

Ok, thank you for the information 👍

[eerimoq]

Implemented it. It's in Test Flight soon.

[fdebbabi]

That was extremly fast 😅 you know that portrait streaming is the only reason I keep using Larix Broadcaster (I bet a lof people need this for IRL)

[eerimoq]

It's in test flight now in case you wanna give it a try. Just enable it in Settings -> Streams -> My stream and go live. Let me know if it works

[fdebbabi]

I have just checked (on iPad), one question, how to enable it in Settings -> Streams -> My stream, I can't find a button to rotate stream or proper 9:16 resolution, i only find rotate in display.

[eerimoq]

it's only supported on iphone

[eerimoq]

can probably be added to ipad

[eerimoq]

was easy to make it work on ipad. will be in test flight in 15 minutes

[fdebbabi]

Stream is working fine, some minor issues I sent via testFlight

[eerimoq]

I need more details on the problem that parts of the video is outside the screen. It's not like that for me on iPhone or iPad. What is you setup? What camera are you using as video source?

[fdebbabi]

Using iPhone SE natif back camera (there is only one)

[eerimoq]

fixed the resolution names

[eerimoq]

looks good on iphone x as well. not sure why the video is partly outside the screen. you got any widgets or anything else you think could affect it?

[eerimoq]

Update to latest testflight again. should have resolution fix

[fdebbabi]

Yes, all of the issues mentioned are now fixed on both ipad and iPhone SE (even the camera that was out of the screen in portrait mode).
One minor issue still left is that icons in portrait mode are slightly cut/out of the screen in iPHone SE (I sent photo using test flight)

[eerimoq]

ok! yeah, the buttons are slightly cut on Mac as well. not sure how to fix it, as I don't want to add padding on phones where it already looks good.

[fdebbabi]

Yes, for me everything is perfect :) that would be good also to share it in discord once accessible directly in app store (multiple people were asking also for it)

Note: I tested on iPhone SE because it is the only iphone I had accesible tonight, iPhone SE is really not for streaming (can't take the stress)

[eerimoq]

fixed the buttons as well. was easy.

[eerimoq]

You can read the release notes in moblin discord server, the releases channel.

[eerimoq]

it's in test flight now

[fdebbabi]

I will check that tomorrow

[fdebbabi]

Buttons are working fine now, portrait mode seems not working when using external camera (DJI Action 4) in iPad, i didn't check the resolution received by the stream, for now I am speaking only about the UI, i believe it should rotate.

[eerimoq]

Added rotation setting in Settings -> Scenes -> My scene just now. It's in test flight.

[fdebbabi]

Now it rotates properly, but when in portrait mode it does not fill enough space in the screen, it would perfect if it is a little bit bigger

[eerimoq]

odd it's not like that for me

[fdebbabi]

I on iPaid Air Model, I will in chech again one hour

[fdebbabi]

Everything works fine now 🤩

[eerimoq]

Goood!

[fdebbabi]

One question, when using external camera, does moblin decodes the received stream from the camera to show it on screen, than re-encodes the decoded one to send it to the destination, or does it send as it is from the source?

[eerimoq]

Everything leaving Moblin is encoded by Moblin.
