[FFmpeg-user] Error while opening encoder....

[Mike Kavanagh]

Hi 

 

I believe this is a fairly basic problem I am having as I am just starting
with ffmpeg.

 

I am creating a video from a set of still images and have been getting an
image size problem which I have tried to solve with a '-vf pad' control
parameter. The pad values I have put in are designed to make the width
divisible by 2 as required and yet not mess up the aspect ratio.

 

Below I provide the report output with the three problem lines in bold - i
am running this on a PC with Windows Vista. 

 

ffmpeg -vf "pad=1340x886" -i "%06d.jpg" -y movie.mp4 -r 1 -b:v 9600 -report

Error while opening encoder for output stream #0:0 - maybe incorrect

Thanks for your help in advance.
