[FFmpeg-devel] [PATCH] lavc/speedhqenc: Require width to be a multiple of 16

["Tomas Härdin" <git@haerdin.se>]

Stop gap solution. I don't know enough about mpegvideo_enc to provide a
proper implementation, nor do I have access to NDI hardware to feel
comfortable with it. This patch at least prevents us from outputting
files that we know are broken
