Combining multiple image files into a video while using filter_complex to apply a watermark
14 décembre 2017, par GeuisI’m trying to combine two ffmpeg operations into a single one.
Currently I have two sets of ffmpeg commands that first generate a video from existing images, then runs that video through ffmpeg again to apply a watermark.
I’d like to see if its possible to combine these into a single operation.
# Create the source video
ffmpeg -y \
-framerate 1/1 \
-i layer-%d.png \
-r 30 -vcodec libx264 -preset ultrafast -crf 23 -pix_fmt yuv420p \
output.mp4
# Apply the watermark and render the final output
ffmpeg -y \
-i output.mp4 \
-i logo.png \
-filter_complex "[1:v][0:v]scale2ref=40:40[a][b];[b][a]overlay=(80):(main_h-200-80)" \

ffmpeg_kit_flutter operation not permitted for audio operations
25 août 2023, par Black Eyed BeansI'm trying to trim an audio file using
ffmpeg_kit_flutter
but I keep getting the error :

audio/path/output.mp3: Operation not permitted.



This is the ffmpeg command that I'm using :


final cmd="-y -i \"$audioPath\" -ss $audioStartTime -to $audioEndTime -c:a libmp3lame $outPutName";



And I've also tried :


final cmd="-y -i \"$audioPath\" -ss $audioStartTime -to $audioEndTime -c copy $outPutName";



But the error is still the same.
I'm using the
ffmpeg_kit_flutter_full_gpl
package.

How to stack several videos using ffmpeg ?
13 juillet 2019, par JohnI have four cameras that are recording videos and wand to stack all videos into one video file. The final video must be a 2x2 grid.
THE HARD PART is that sometimes cameras are not recording simultaneously.
Here you can see one situation of how cameras are recording :
Camera 1 timeline: |recording....................................|
Camera 2 timeline: |stopped....|recording........................|
Camera 3 timeline: |recording.........|stopped....|recording.....|
Camera 4 timeline: |recording..................|stopped..........|Explanation :
- Camera 1 is recording all time.
- Camera 2 is starting recording later.
- Camera 3 is recording, then stopped a period of time, then again recording.
- Camera 4 is recording a period of time, then stopped.
In the final video I want to synchronize each video by timestamps.
If a camera is stopped a period of time then at its position must be a black portion.
How can I do this ?
