[FFmpeg-user] Programmatically convert a sequence of jpeg files and a wav file into a video file

[Pierrick Chabi]

Thank you Moritz,

Thank uou for the "script". So, to achieve the "prgramatically" part of my
request, is there a way to write a c program ( thatlink it to ffmpefg
libav* libs) that executes that script (not in command line mode) ?

Cheers,

P
