AFAICT, ffmpeg seldom updates any doc that isn't auto-generated from the
source code. OTOH, it's free software.
And you probably know by now that a full command output is almost always
needed.
ffmpeg -f image2 -i image.jpg -vcodec libx264 -b:v 200k -t 30 out.mp4
Error initializing output stream 0:0 -- Error while opening encoder for
output stream #0:0 - maybe incorrect parameters such as bit_rate, rate,
width or heigh
[no output included]
(The encoder doesn't know about the desired frame rate/etc; you need to
specify them. Look at the -target option; unfortunately the parameters it
actually sets are only documented in fftools/ffmpeg_opt.c).
z!
