ffmpeg : create a video from images and sounds
27 septembre 2018, par Yuri GusakYou need to create a video from a set of pictures and sounds using ffmpeg.
Set of pictures : frame_% d.jpg
Sounds :
sound1.mp3 (from 0 ms)
sound2.mp3 (from 1000 ms)
sound3.mp3 (from 2000 ms)I can create a video with one sound :
-i frame_% d.jpg -i sound1.mp3 -r 30 -s 1280x720 -preset ultrafast -crf 25 -shortest movie.mp4
and it works.
But I need to add some sounds at different times. How can I do that ? May be -filter_complex will help ?

Converting imges to video
19 janvier 2014, par DanMI am using external camera with my application. The camera takes 9 pictures every second (9fps). The pictures are bitmaps 384x288. I need to create from this pictures a video file.
What I have tried :
- Using Jcodec
The problem : jcodec is relatively slow, and for it to work properly i add the bitmaps to ArrayList and when the record stopped i convert the array to video. I takes to much time. For 30 sec video there is about 1 min rendering time.
- Using native mediaCodec
The problem : I could only generate AVI files (video/avc) that not readable in the original android player. I can not use what is written here : http://bigflake.com/mediacodec/ because I developing for API 16. I have tried using (video/mp4v-es) but the video is corrupted and not playable in any player.
- Using FFmpeg
The problem : Very complicated to implement in android, and I am not sure it will give me the result I needed after spending time to implement this. The result I need is to record video streaming as I get the bitmap without any delay.
What can you suggest me ?
