[FFmpeg-user] create video from image

[juan carlos]

I already indicated in another email that since the release of ffmpeg 
4.0 the project does not take seriously the work of updating the 
documentation, no command posted in the different pages referring to the 
project works correctly, in the previous one I tried to use a format 
that according to you It was not supported anymore, but it is not 
mentioned anywhere so I can not know if that is true, this time I have 
errors trying to create a video from an image

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
