The command look like :
ffmpeg -i bg.jpeg -i img_%d.png -filter_complex overlay=5:H-h-5[b]-shortest testvid.mp4

The input
-i img_%d.png
meansimg_0.png
,img_1.png
,img_2.png
, ...But I have custom sequence like this :
{img_0.png, img_1.png, img_1.png, img_2.png, img_1.png, img5.png, img_4.png}

How to speedup image processing (e.g. resizing, jpeg compress, encode) using ffmpeg command line utility from python on windows
28 mars 2020, par MSD PaulI am running ffmpeg commands to downsizing and jpeg compression of a 4K image using command prompt on windows 10. But its taking a long time. To downsize, jpeg compress and finally encode to a video file it takes more than 500 ms.
I can’t do the processing on images on batch but I have tried -hwaccel and -threads option (also -loglevel quiet for suppressing the logs being printed) in order to speedup the ffmpeg processing. Can someone please guide me towards how can I possibly speedup the ffmpeg command processing.
Is it possible to pass the image files already read into memory using read() API to the ffmpeg command ?
Please also let me know if there exists any other possible speedup techniques.
