[Android] - [Question] Create video from in memory images?

[vieraleonel]

Hi. I have a Java Android app that writes between 30 to 50 images to disk then produces a mp4 video. Originally I have them in byte[] format but turn them into JPEG Bitmaps that then are written to files. I some conditions, this process is a bit slow, mainly because all the writing and consequent reading of the image files.

Is there any way to pass the in memory list of byte[] or list of Bitmap to ffmpeg input in order to prevent all the initial writing operations?

For reference the command im using is:

-f concat -i imagest.txt -c:v mpeg4 -pix_fmt yuv420p -framerate 50 -b:v 2000k video.mp4

Note: I also can't get to work the command with input 'image%d.jpeg' so I end up using concat with a text file as input.

We don't have that kind of API yet. However, we plan to implement it since many developers have been requesting it.

¿Es posible pasar a el kit, los bitmaps uno a uno para que se construya el video a medida que se va generando los bitmaps y luego que al finalizar el pase de parametros, se construya el video?
