How can I resize an overlay image with ffmpeg ?
28 novembre 2020, par Andrei DascaluI am trying to add an overlay to a video using the following command


ffmpeg -y -i "$videoPath" -i "$overlayPath" -filter_complex "[0:v] [1:v] overlay=$overlayPosition" -pix_fmt yuv420p -c:a copy "$outputPath" 



However, I would like to be able to resize the overlay I am about to apply to some arbitrary resolution (no care for keeping proportions). However, although I followed a couple of similar solutions from SO (like FFMPEG - How to resize an image overlay ?), I am not quite sute about the meaning of the parameters or what I need to add it in my case.


I would need to add something like (?)


[1:v]scale=360:360[z] [1:v]overlay=$overlayPosition[z]



This doesn't seem to work so I'm not sure what I should be aiming for.


I would appreciate any assistance, perhaps with some explanation.


Thanks !

Converting bin& format to mp4 with ffmpeg fails
31 octobre 2017, par VincentI am trying to download videos from Wistia and I managed to download them but in .bin& format ; I’d like to convert them to .mp4 in order to use OpenCV. For this I am calling ffmpeg with subprocess on Python but I get 1 as the value for the return code, meaning the process has failed. Any idea why, and how I can change this...?
Code is the following :
import subprocess
infile = filename #a bin&amp file
outfile = filename[:-7]+'mp4'
subprocess.run(['ffmpeg', '-i', infile, outfile],shell=True)I get :
CompletedProcess(args=['ffmpeg', '-i', '58c63bccfcc1c150646c261caad97a58ced4b5e3.bin&amp', '58c63bccfcc1c150646c261caad97a58ced4b5e3.mp4'], returncode=1)
Also, it works in the command prompt...
Thank you for your help,
Sincerely,
