In the command line below,
I will eventually insert a screen maker --+
¦
separatefields,scale=height=2*in_h:sws_flags=neighbor,--HERE--,tblend=normal[D]
but first, I need to persuade 'tblend' to accept the 2 frames made by 'separatefields' (and scaled
by 'scale').
But as you can see in the next section (extracted from the log), though the 'height=2*in_h'
directive works (i.e., the 1920x540 frames from 'separatefields' are scaled to 1920x1080), ffmpeg is
not happy. Is it because the SARs don't match? How can I overcome that?
Thanks!
