FFMPEG and libavfilter
21 mars 2012, par SergioWith the currently installed ffmpeg I can't post watermark on converted videos. Can the reason for that be that I have not installed libavfilter library ?
Currently # ffmpeg -v looks like :

libavdevice 52. 2. 0 / 52. 2. 0As you can see I'm missing libavfilter ? How can I add that library to FFMPEG and successfully add watermark on videos ?
Thanks for any help.

23 mars 2012, par user974435I am using followng command to convert video to webm format
ffmpeg -i video/ds2.mp4 -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b:a 345k -s 640x360 video/ds2.webmI am receiving following errors :
1) incompatible sample format 's16' for codec 'libvorbis'
2) strptime() unavailable on this system, cannot convert the data string

FFmpeg - Concatenating videos with different resolutions
7 août 2017, par JillI currently have an android app where the videos get combined using ffmpeg’s concat. That works fine. However, when I add text (using drawtext) to one of the videos, after combining the videos again, the combined video gets distorted. The video with the drawtext shows up fine, but then the videos without text switches orientation.
I think the problem roots from the fact that a vertical video on my android phone has the resolution of 1920x1080, however if I use that for the scale when executing drawtext, it becomes horizontal.
I think an example might help explain this better. Let’s say I have 2 vertically recorded videos, and I combine them with concat. The combined video shows up fine. Then if I add text to the 1st video using drawtext, the combined video will then show the first video (with text) at normal orientation (vertical). However, when it transitions to the next video, it first stalls for a couple seconds and then the 2nd video is shown at a horizontal orientation.
Also, I tried this also with having the aspect ratio as 1:1 so it wouldn’t matter, but the second video’s orientation still changed counter clockwise.
Thanks for the help, and happy to add more clarification if needed.
This is for adding the text :
ffmpeg -i input.mp4 -vf drawbox=y=ih-200:color=black@0.5:width=iw:height=200:t=max
,drawtext=fontfile=RobotoRegular.ttf:text='Text':x=(w-text_w)/2:y=(h-text_h)-100:fontsize=70:fontcolor=white
