ffmpeg encoded video has video/audio sync delay when uploading to Facebook & WhatsApp
13 décembre 2019, par royherma"fluent-ffmpeg": "^2.1.2",
"ffmpeg": "^0.0.4",
node : 8Code to reproduce
let command = ffmpeg()
.input(tempFilePath)
.input(watermarkFilePath)
.complexFilter([
"[0:v][1:v]overlay=W-w-20:H-h-20"
])
.videoBitrate(2500)
.videoCodec('libx264')
.audioCodec('aac')
.format('mp4')
.output(targetTempFilePath)When applying the ffmpeg encoding command on the attached video, it plays fine on a local device - the issue however is when uploading to Facebook/WhatsApp the audio/video becomes out of sync
Any ideas on what i need to change in terms of the video/audio settings so that the audio + video are in sync, even when uploaded to the various social networks ?
Here’s a link to the 3 video files (original, post ffmpeg, post whatsapp upload that includes delay) if you want to get a better idea !

how to add overlay at the end of video without knowing time duration of video file - ffmpeg
13 décembre 2019, par Luka mikicI have a bunch of video files to which I add animated overlay at the beginning of video, but I would like to add it again at the end of it t-13 seconds. This is my bash script :
do
ffmpeg -i "${f}" -i /app/logo/lower.mov -i /app/logo/logo.png -filter_complex \
"[0:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:x=(1280-iw)/2:y=(720-ih)/2:color=black[bg0]; \
[bg0][1:v]overlay=10:10[bg1]; \
[bg1][2:v]overlay=10:10,drawtext=fontfile=/app/logo/Courier Prime.ttf:text=$(basename "${f}" | cut -f 1 -d '.'): \
fontcolor=white:fontsize=25:x=256:y=h-th-130:alpha=1:enable='between(t,2,15)'" \
-c:v libx264 -crf 21 -preset ultrafast "${f%.*}.mp4" -y
doneIs there any way to do this ? I know how to extract the duration with FFProbe, but do not know how to add duration dynamically to a variable and then apply it to code I have.
