error checks are "< 0" in ffmpeg unless something else is dicatated
by external API

also this fails build:

ffmpeg/libavcodec/pngenc.c: In function ‘encode’:
ffmpeg/libavcodec/pngenc.c:463:46: error: ‘row_size’ undeclared (first use in this function)
ffmpeg/libavcodec/pngenc.c:463:46: note: each undeclared identifier is reported only once for each function it appears in

Many that live deserve death. And some that die deserve life. Can you give
it to them? Then do not be too eager to deal out death in judgement. For
even the very wise cannot see all ends. -- Gandalf
