FFmpeg downscale video while maintaining aspect ratio SAR and DAR
12 avril 2023, par SolarisHow can I resize the video (eg 1080x ? to 480x ?) while maintain aspect ratio (SAR and DAR) ?
I want to use the output video to create Dash MPD


I tried multiple filters

-filter:v 'scale=854:480'

-filter:v 'scale=-1:480'

-filter:v 'scale=-2:480'

-filter:v 'scale=854:480:force_original_aspect_ratio=decrease,pad=854:480:(ow-iw)/2:(oh-ih)/2,setsar=sar=1'


But can get exact SAR and DAR , at least ffmpeg
-f dash
doesn't allow both streams to be in same adaptation set

Option to generate a .m4s file every second
15 octobre 2020, par Adrian AngkajayaI am trying to stream my live recording from a camera (web cam/ IP cam) to my web application. The streaming technique I use is MPEG-DASH, which has manifest in MPD format. To generate an MPD format from the web-cam, I use FFmpeg tool in shell command line :


ffmpeg -re -y -f dshow -i video="Logitech HD Webcam C525" -c:v libx264 -c:a libfdk_aac -f dash "manifest.mpd" 



This code will generate a video chunk in .m4s format every 5-8 seconds.


Question is, what FFmpeg option can I use to generate a .m4s file every second instead of every 5-8 seconds ? I suppose it has something to do with segment ?
