How to convert a lump set of PPM files to a single .mp4 video using ffmpeg
4 août 2021, par Nash G-LI'm trying to convert some
.ppm
files into a single video using ffmpeg. The images are listed asimage10.ppm
,image20.ppm
, all the way up toimage2000.ppm


Essentially, there are 200 images following the format of
image(1-200)0.ppm
in a single folder.

I've navigated to the correct folder containing the images using
cd
and the terminal displays this folder as the directory I'm in.

Inputting the following command into the terminal :


ffmpeg -r 10 -f image2 -s 500x500 -i image%04d.ppm -vcodec libx264 -crf 25 -pix_fmt yuv420p presentation_video.mp4



I get the error that says :


[image2 @ 0x7ff36180ba00] Could find no file with path 'image%04d.ppm' and index in the range 0-4
image%04d.ppm: No such file or directory



What am I missing ? I've just downloaded ffmpeg and am fairly new in general to command line interface.

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 ?

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.
