Overlay two sequences of png's and turn them into a movie
12 mai 2014, par Lau LlobetI’ve found how to turn a png sequence into a movie and I’ve found how to overlay two movies using transparency but I don’t know how to do both things at once (using png’s transparency).
The bottom layer of png’s is smaller than the top one and needs to be stretched to a certain resolution and also have a padding to be centered.
The output doesn’t have to have alpha (black for alpha is ok). I’m a bit confused by the abundance of filter options.
For the moment I’ve found :
./ffmpeg -i ./seq1/%d.bmp -vf "movie=./%d.png [a]; [in][a] overlay=0:366" combined.m2v
It works, now I’ve got to find the padding and resize things

Amazon Alexa Audio Encoding- Few audios are not playing [closed]
3 mars 2023, par Vijayanath ViswanathanI am encoding audio for Alexa audio using ffmpeg like below,



ffmpeg -i -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 




The problem is few of the audios are playing properly but few are not. I am using same Project Rate and Quality (Project Rate 16000 and Quality to 48 kbps) for all audios which needs to be converted. Anybody knows is there any basic quality for source.mp3 to encode to Project Rate 16000 and Quality to 48 kbps ?



The response I am getting from alexa for faulty file is, "There is a problem with skill response".
