mjpeg enc yuvj444p: broken output

[ami_stuff]

maybe because width (the same problem happens with height) is not dividable by 16

Isn't this a duplicate of ticket #1990?

[ami_stuff]

Replying to cehoyos:

Isn't this a duplicate of ticket #1990?

Not exactly, now jpeg created by ffmpeg decodes in other apps (that was not the case in #1990), but the output is broken for sizes not dividable (probably) by 16 (640x480/ 1024x768 etc. is ok).

[Carl Eugen Hoyos]

The output image looks very broken with ffplay, ImageMagick and Gimp, from a user's perspective this is a regression.
