Hi
I have a 360 video and I need to rotate the stating angle.
I want to have the same resolution and bitrate, but just rotate the video by 180.
Currently I manage todo so by running this command:
Working... but super slow (about X0.1).Code:ffmpeg -i "FileName" -vf v360=e:e:yaw=180:pitch=0:roll=0 "OutputFile"
I would like to use my RTX3080 capabilities for that,
Any suggestions how?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Specify h264_nvenc as the video codec.
Code:ffmpeg -i "FileName" -vf v360=e:e:yaw=180:pitch=0:roll=0 -c:v h264_nvenc "OutputFile"

Thanks @jagabo!
I've added additional flag to keep the high quality
Code:ffmpeg -i in.mp4 -vf v360=e:e:yaw=180:pitch=0:roll=0 -c:v h264_nvenc -gpu 1 -preset slow -b:v 100M out.mp4

About X16 faster.
But now I have another problem, Seems that h264_nvenc doesn't support large resolution video.
Getting this error when trying to rotate a 5760x4096 video using this command:
Code:ffmpeg -i FirstPart.mp4 -vf v360=e:e:yaw=180:pitch=0:roll=0 -c:v h264_nvenc -gpu 0 -preset slow -b:v 100M FirstPart_flipped.mp4
Code:[h264_nvenc @ 0000019d2ed000c0] Width 5760 exceeds 4096 [h264_nvenc @ 0000019d2ed000c0] No capable devices found Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height [aac @ 0000019d2bf23ec0] Qavg: 262.028 [aac @ 0000019d2bf23ec0] 2 frames left in the queue on closing Conversion failed!

Same RTX 3080? You switched from gpu 1 earlier to gpu 0 now. I'm pretty sure the RTX 3080 supports up to 8K width. Maybe it's a combination of the 5760 width and bit depth, color format, frame rate...

Found a solution with changed the codec from "h264_nvenc" to "hevc_nvenc" that's seems to work.
Although the video isn't playable in windows player even with the right codec :\
