.jpg files as frames to generate a .mp4 video file with FFMPEG

[Quentinnod]

Hi, I am creating an app which would allows the user to generate a video with the images that compose the video. I succeeded in doing this on my computer with FFMPEG cmd and three pictures :

ffmpeg -framerate 1/5 -i img%03d.jpg -c:v libx264 -r 30 -pix_fmt -yuv420p out.mp4

But when I execute the following command I get no result:

cmd = ['-framerate', '1/5', '-i', '/storage/extSdCard/DCIM/Camera/img001.jpg /storage/extSdCard/DCIM/Camera/img002.jpg /storage/extSdCard/DCIM/Camera/img003.jpg', '-c:v', 'libx264', '-r', '30', '-pix_fmt', '-yuv420p', '/storage/extSdCard/DCIM/Camera/out.mp4'];

VideoEditor.execFFMPEG(ffmpegSuccess, ffmpegError; {cmd: cmd});

Is it possible to execute this command with the plugin ?

Thanks a lot !! This plugin would be an awesome solution I i can do what I want to do.

Is the ffmpegSuccess or ffmpegError called? If the error callback is ran what is the error? Anything helpful in logcat?

[Quentinnod]

Thank you for your fast answer !!

Here is my logcat:

I cut this part of logcat to get more readability before the "shellOut": 05-17 13:24:44.765 31433-31728/com.quentin.myAppTest D/VideoEditor: + shellOut...

The logcat stops at the last line and nothing happens...

It works with one image as input (with success callback)but when I want multiple input image files it stops.

Thanks a lot Ross

[Quentinnod]

Do you have an example using multiple input files as image frames to generate a video ?

[rossmartin]

There is an example in the android-ffmpeg-java library I'll dig it up later.

Can you try adding -y before your -i in your ffmpeg command?

'-framerate', '1/5', '-y', '-i', '/storage/extSdCard/DCIM/Camera/img001.jpg /storage/extSdCard/DCIM/Camera/img002.jpg /storage/extSdCard/DCIM/Camera/img003.jpg', '-c:v', 'libx264', '-r', '30', '-pix_fmt', '-yuv420p', '/storage/extSdCard/DCIM/Camera/out.mp4'

[Quentinnod]

Thank you for your answer. Adding -y to my cmd was very helpful !! I succeeded in generating a .mp4 file but only with .png images.

Helpful link : https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

Do you know how to use .jpg files ?

Moreover I had to change the file path name by /storage/extSdCard/DCIM/Camera/img%03d.png to add all the images with a imgxxx.png file format name. I took 5 png pictures named img001.png img002.png img003.png img004.png img005.png. And it works by executing the following command:

'-framerate', '1/5', '-y', '-i', '/storage/extSdCard/DCIM/Camera/img%03d.png', '-c:v', 'libx264', '-vf', 'fps=30', '-pix_fmt', 'yuv420p', '/storage/extSdCard/DCIM/Camera/out.mp4'

Thank you again !

Did you manage to get this to work with Jpg files?

I am looking into creating an MP4 file from images taken with the camera - which are JPEG. Is this a viable option? Did it work for you?

[Quentinnod]

Yes it's possible. You can do it with ffmpeg with a command line. You put in parameters the pictures jpg and the parameters like the frame rate. I don't have the code with me but you would find it on the web

wow thanks for reply.

Did you do this from within a cordova android app? Thats what I am trying to do and at the moment failing (with another project that converts to webm format first).

I can get the images together, but need to be able to play them as a movie on the device, full screen.

[Quentinnod]

I used it within a Cordova app but it works only with android because the plugin which allow ffmpeg command line is only available with this OS

If you want to make a movie with the images used like video frames you would get bad quality and the time to produce such a video is very long and it consumes a lot of CPU.

But if you want just a slideshow it would be good

what is the difference between movie and slideshow? I have just got it running, but yes it is slow. I need to stitch 30 camera images together to make an MP4 file - 3 seconds each.
