Rotate video according to rotation metadata and strip off metadata using ffmpeg [on hold]
12 décembre 2018, par this.lau_I’ve got a video with the following metadata :
Metadata:
rotate : 90
creation_time : 2018-12-03T16:13:47.000000Z
handler_name : VideoHandle
Side data:
displaymatrix: rotation of -90.00 degreesAnd I would like to remove this metadata and rotate the video by whatever rotation value is found there (in this case -90 but it can be anything).
The result will be a video with the correct orientation and that works with all video players (including those that don’t auto-rotate based on the metadata).
I’ve tried various commands but couldn’t find anything that would work. Any idea how to do this ?

Overlay a video on another video at specific time with FFmpeg
4 janvier 2019, par Tina JI am trying to overlay a video with another video. I followed the original command OP posted here. And it works, but it overlays the video from time 0 :
ffmpeg -i 720480.mp4 -i sdbug.mov -filter_complex "[0:0][1:0]overlay[out]" -shortest -map [out] -map 0:1 -pix_fmt yuv420p -c:a copy -c:v libx264 -crf 18 new.mp4
I tried the correct answer to specify a time, but it is not working for me : 1) the overlay starts at around second
12
, and 2) video is not played after the overlay is finished.ffmpeg -i 720480.mp4 -i sdbug.mov -filter_complex "[1:v]setpts=PTS+10/TB[a]; [0:v][a]overlay=enable=gte(t\,5):shortest=1[out]" -map [out] -map 0:a -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a copy new.mp4
Anything changed recently on
FFmpeg
?! Why isn’t it working ?Here is the output of this command (it finishes very fast) :
