make a .flv from a bunch of jpeg-s

Question

I have a bunch of jpeg and want to make a single flv video file from it.

I need flv/mp4 (vp6/h264 codecs).

Could you please tell me how to do it?

It must be done via console command on Linux.

Answer 1

I dont have ffmpeg to try but...

Join images to movie

First, rename your pictures to follow a numerical sequence. For example, img1.jpg, img2.jpg, img3.jpg,... Then you may run:

ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg

Notice that %d is replaced by the image number.

Convert mpg to flv
ffmpeg -i <input-file> -acodec mp3 -ar 11025 -f flv -s 320x240 -y <output-file>

I suspect you can skip the two step process and convert directly to flv in the first step but can't experiment on this computer.
