Using FFMPEG Args

[eskapiste]

Hi there guys! I am trying to setup a restream to various platforms, including Instagram. The problem with instagram is that, originally?, i have 16:9 video (1920*1080) and by default it appears in instagram without rotation and that means that i can only see a small portion of original frame. I tried to rotate my video by 90 degrees in OBS and it does the trick, but the thing is that i need my video to be restreamed without rotation to platfroms such as Facebook, Youtube etc and with 90 degrees rotation to Instagram. I tried to use FFMPEG args but it didnt work, it does not send anything to any platfrom if i write some specific arguments. I tried these combinations

ffmpeg -c:v copy -metadata:s:v rotate="90" -c:a
ffmpeg -i input -vf transpose=2 output ffmpeg -c:v copy -vf transpose=2 -c:a

i dont have enough knowledge about using arguments so i want to ask for your advice how to use it properly to rotate my video for only one destination.

Thanks!

Did you have ffmpeg in the arguments? Try removing that

nope, i didnt use ffmpeg at the beginning. the only arguments that work are "-c:v copy -c:a copy" but those are default ones. how should i insert a rotation argument in here?

i tried these options - none of them work:

-c:v copy -metadata:s:v rotate="90" -c:a copy -c:v copy-vf transpose=2 -c:a copy

Unfortunately, I'm not familiar with how to stream video to instagram, what they're expecting, etc. Last I checked they don't have an public API for live video.

I do know if you're doing a video filter (-vf transpose=2), you can't use the copy codec, you'll have to re-encode.

I would suggest making a pre-recorded video locally, and figure out how to stream to instagram with ffmpeg locally first, like:

ffmpeg -re -i some-premade-video.mp4 -c:v copy -c:a copy -f flv rtmp://whatever/the/url/for/instagram/is

That -c:v copy -c:a copy section is the part of the CLI you'll want to edit and paste into your ffmpeg arguments.

lets put IG aside. i tried these strings for youtube too,

-c:v copy -metadata:s:v rotate="90" -c:a copy -c:v copy-vf transpose=2 -c:a copy

it didnt wor.l.

i ll try your option for sure. and what should i put instead of "some-premade-video.mp4" if i am restreaming live video?

I've been considering discontinuing this project for some time now. I'm sorry I couldn't solve your issue, but I just don't enjoy working on multistreamer anymore.
