FFmpeg : Combine video files with different start times
18 mai 2016, par FabianI have two webm files with audio and video recordings of a video conference session. Both files only contain one side of the conversation. They are not of the same length (someone has joined before the other one), but I have the unix timestamp in milliseconds of the start time of each video file.
On a timeline they look like this :
webm 1: -----------------------------------------------
webm 2: -----------------------------or like this :
webm 1: -----------------------------------------------
webm 2: -----------------------------I would like to combine these two video files into one file so that :
- They appear next to each other (using the hstack option), and
- That they are mixed with taking the time stamps of the start times
into account. The final video should then look like this :
Target result : --------------===========================----
The beginning and the end of the new video would show a black placeholder for the video file that has no data at this time of the mixed stream.
At the moment I use this command :
ffmpeg -i 1463408731413703.webm -i 1463408880317860.webm -filter_complex \
"[0:v][1:v]hstack=inputs=2[v]; \
[0:a][1:a]amerge[a]" \
-map "[v]" -map "[a]" -ac 2 -c:v libvpx output.webmThis creates a video like this :
Not good result : =====================------------------
i.e. the conversation is out of sync.
How can I combine two video streams with different length and different start times using ffmpeg so that I will end up with "Target result" above ?
Thanks a lot !
