Google Speech Recognition API output errors, unsure why they're occuring
8 novembre 2019, par Requiem_7This is the output for when I feed flac files into Google’s Speech Recognition API. It says that if starts and finishes most of the files but then it gives me these errors when it nears the end. I have checked and all these files are native flac files. I took out a good chunk of the output above "source/out70.flac started" becuase it’s all the same besides the file number.
source/out70.flac started
source/out25.flac started

ffmpeg overlay png on video has color issue
9 janvier 2023, par RichardIm trying a simple overlay command to put a logo on a black video, but find the color a little different in output, the original RGB value of green part of the logo is (0,220,90), but changed to (0,191,88) in output. Looks like the color gets mixed with the black background, any ideas ?


original logo rgb :




rgb after logo overlayed on video :




the command to overlay :


ffmpeg -i video.mp4 -i logo.png -filter_complex "[1:v]format=rgba[s],[0:v][s]overlay=240:1275:format=auto" output.mp4
