ffmpeg Loop the short video so it can match the duration of the a long audio [closed]
16 avril 2024, par andrew cumminsI have a list of mp4 files and mp3 files in a directory. I need the following


- 

- loop the short mp4 so it can match the duration of the mp3 file
- export mp4 file with new audio.
- But we want the mp4 in portrait mode.








ffmpeg -stream_loop -1 -i video.mp4 -i audio.mp3 -map 0:v -map 1:a -preset slow -shortest -movflags +faststart output.mp4


I have this code in ffmpeg, but i would need to have output in portrait mode.


the code works, but the issue is having the video output in portrait mode without stretching the video.

dockerized python application takes a long time to trim a video with ffmpeg
15 avril 2024, par Ukpa UchechiThe project trims YouTube videos.


When I ran the ffmpeg command on the terminal, it didn't take too long to respond. The code below returns the trimmed video to the front end but it takes too long to respond. A 10 mins trim length takes about 5mins to respond. I am missing something, but I can't pinpoint the issue.
