FFMPEG Question - Upside down videos & stretching. - GoFuckYourself.com

JSWENSON · 07-19-2015, 08:22 AM

Trying to figure out the best FFMPEG command to use.

I have this

Code:

$ffmpeg_command = "-acodec libfaac -keyint_min 20 -r 20 -vcodec libx264 -crf 22 -b 1000k -bt 1000k -y -v 0 -bf 16 -vf 'scale=-640:480' -threads 0"; //settings for ffmpeg encoding

but some videos are upside down

and vertical videos are stretched all funky.

Any suggestions? Thanks in advance.

Could be the player too I suppose. MechBunny defaults.

Remove -vf parameters replace with -vf 'crop=240:0:1440:1080,scale=640:480' change sizes to your params hard to see your code ond my phone scrolling that fucking "code" box

Note: if it's just Iphone videos flipping use this Safari code to correct "-metadata:s:v rotate=0"
