ffmpeg command to convert 720p to 1080p, 1440p, 2160p compatible with YouTube [closed]
24 juin 2024, par Tendekai MuchenjeI have a video that I created in Final Cut Pro. When i uploaded it to Youtube, it only maxes out at 720p. I would like it to have higher options like 1080, 1440 and 2160 even if the quality does not change. Maybe 2160 is impossible, but 1440p would be nice. I have tried this command, but the resulting file is unplayable, it only plays audio.


ffmpeg -i Hey\ Girl.mov -vf scale=3840x2160:flags=lanczos -c:v libx264 -crf 13 -c:a aac -b:a 512k -preset slow hey_girl_hd.mov



I am looking for a command that would make at least 1080 and 1440 work on YouTube. If 2160 can work, that would be great too. If it matters, here is all the info that ffprobe throws out about the file

I send video stream from mobile app over rtmp encoded with hevc to my laptop where running script
ffmpeg -f flv -listen 1 -i rtmp://192.168.0.194/s/streamKey -c:v libsvtav1 -f mpegts srt://192.168.0.167:9998?mode=caller
. On the desktop i have obs with media source inputsrt://192.168.0.167:9998?mode=listener
.

When i run ffmpeg script without video codec option (-c:v libsvtav1) its working fine and in obs i can see video from my phone camera. With the option i can not see video only audio.
I clearly dont understand warning message :
[mpegts @ 0x55ec921d9540] Stream 0, codec av1, is muxed as a private data stream and may not be recognized upon reading.
.
Do I need specify codec (av1) in obs media source or my ffmpeg script is wrong ?
